THE SUN

The international Hinode solar-observing satellite captured the transit of Mercury as it passed between Earth and the Sun on Nov. 11, 2019. Transits like this can be used to measure the distance between Earth and the Sun. Hinode is a joint endeavor by the Japan Aerospace Exploration Agency (JAXA), National Astronomical Observatory of Japan (NAOJ), European Space Agency, United Kingdom Space Agency and NASA. These images were taken with Hinode's X-Ray Telescope (XRT), which observes the solar atmosphere at millions of degrees. Additional movies from the XRT are available from the Harvard-Smithsonian Center for Astrophysics and JAXA. Image credit: JAXA/NASA/SAO/Montana State University/NAOJ

Welcome to Amazing Space Videos - This video of one month of solar activity was created using images from NASA SDO - almost 3000 separate photos were used. A few facts about the Sun FACTS ABOUT THE SUN The Sun accounts for 99.86% of the mass in the solar system. It has a mass of around 330,000 times that of Earth. It is three-quarters hydrogen and most of its remaining mass is helium. Over one million Earth’s could fit inside the Sun. If you were to fill a hollow Sun with spherical Earths, somewhere around 960,000 would fit inside. However, if you squashed those Earths to ensure there was no wasted space then you could fit 1,300,000 Earths inside the Sun. The surface area of the Sun is 11,990 times that of Earth. One day the Sun will consume the Earth. The Sun will continue to burn for about 130 million years after it burns through all of its hydrogen, instead burning helium. During this time it will expand to such a size that it will engulf Mercury, Venus, and Earth. When it reaches this point, it will have become a red giant star. The energy created by the Sun’s core is nuclear fusion. This huge amount of energy is produced when four hydrogen nuclei are combined into one helium nucleus. The Sun is almost a perfect sphere. Considering the sheer size of the Sun, there is only a 10 km difference in its polar and equatorial diameters – this makes it the closest thing to a perfect sphere observed in nature. The Sun is travelling at 220 km per second. It is around 24,000-26,000 light-years from the galactic centre and it takes the Sun approximately 225-250 million years to complete one orbit of the centre of the Milky Way. The Sun will eventually be about the size of Earth. Once the Sun has completed its red giant phase, it will collapse. It’s huge mass will be retained, but it will have a volume similar to that of Earth. When that happens, it will be known as a white dwarf. It takes eight minutes for light reach Earth from the Sun. The average distance from the Sun to the Earth is about 150 million km. Light travels at 300,000 km per second so dividing one by the other gives you 500 seconds – eight minutes and twenty seconds. This energy can reach Earth in mere minutes, but it takes millions of years to travel from the Sun’s core to its surface. The Sun is halfway through its life. At 4.5 billion years old, the Sun has burned off around half of its hydrogen stores and has enough left to continue burning hydrogen for another 5 billion years. Currently the Sun is a yellow dwarf star. The distance between Earth and Sun changes. This is because the Earth travels on a elliptical orbit path around the Sun. The distance between the two ranges from 147 to 152 million km. This distance between them is one Astronomical Unit (AU). The Sun rotates in the opposite direction to Earth with the Sun rotating from west to east instead of east to west like Earth.

This episode of Weather News is sponsored in part by 3ric Johanson: http://instagram.com/scubist A new sunspot has emerged on the Earth-facing disk and it has been firing a bunch of mini-solar flares, which could be causing just a tiny bit of noise on the dayside amateur radio bands. As of yet it hasnt launched any solar storms towards Earth, but we are watching it closely. We also have a coronal hole in the southern hemisphere that will be rotating into the Earth-strike zone within the next day or so. Aurora photographers at high latitudes might also be in for some fun as we could get sporadic aurora shows over the next few days from the coming fast solar wind. However, the chances of mid-latitude aurora is pretty fleeting. Despite this new activity, solar flux will remain in the high 60's with poor radio propagation in general on Earth's dayside and GPS reception should remain good, even at low latitudes. Learn the details of the new active region, what to expect with the coming fast solar wind, and see what else the Sun has in store. Want early access to these forecasts and more?

This episode of Weather News is sponsored in part by 3ric Johanson: http://instagram.com/scubist Our Sun remains quiet this week, but a promise of a solar storm is rotating into view! A familiar set of coronal holes have survived their passage on the backside of the Sun and are returning. The last time these holes crossed the Earth-strike zone they sent us some fast solar wind that caused a G1 solar storm and brought aurora deep into mid-latitudes. We will get another chance very soon to see if they can do it again! Meanwhile, solar flux remains low so radio propagation is still poor on the dayside of Earth. However, the low solar flux is contributing to decent GPS reception, even at low latitudes. Learn more about the returning coronal holes, when we should expect another solar storm, how the local satellite environment is doing, and what else our Sun has in store.

Declassified Vietnam War files are showing researchers the unpredictable nature of the Sun and helping them work toward predicting the next big solar storm. » Subscribe to Seeker! http://www.youtube.com/subscription_center?add_user=dnewschannel » Watch more Focal Point! | https://bit.ly/2Z7LHgi Traveling at the near-speed of light, energetic particles shooting out from the Sun can zip through space, smack into our planet’s atmosphere, and cause incredible disruptions. And one of the biggest impacts we know of happened during the tail end of the Vietnam War. On this episode of Focal Point, we hear from Delores Knipp, a space weather scientist and former officer in the U.S. Air Force who uncovered a war mystery that is now connected to a major solar event. And Howard Singer, the chief scientist at the NOAA Space Weather Prediction Center. In 1972, a solar flare, or solar storm, traveled at about 2,800 kilometers per second, which was seven times faster than the norm, and it carried tremendous magnetic field, and mass with it. A dozen sea mines exploded and everyone chalked it up to Vietnam warfare, but it was actually the solar flares. The bits of Sun slammed into the Earth’s magnetosphere within 15 hours and triggered the sea mines. So how much do we know about solar flares and what's the chance another event could happen again?

This episode of Weather News is sponsored in part by 3ric Johanson: http://instagram.com/scubist Our Sun calms down this week as region 2745 rotates off the west limb and on to the backside. We are dealing with a slight enhancement due to some mildly fast solar wind that could bump us to active conditions over the next few days, but only at high latitudes. On a more exciting front, a returning set of coronal holes rotates into view, which could bump us to storm levels with some decent fast solar wind in about 10 days. This should give aurora photographers something to anticipate. Unfortunately, the bright regions that were sandwiched between these coronal holes have decayed severely. They will not boost the solar flux much, if at all, for amateur radio operators and emergency responders. This means radio propagation will remain poor on Earth's dayside for at least another week or (likely) more. At least the quiet Space Weather means GPS users can expect great reception on Earth's dayside and at low latitudes over the next week. Want early bird viewing of these forecasts?

This episode of Weather News is sponsored in part by 3ric Johanson: http://instagram.com/scubist This week our Sun gives us one more reason to believe Solar Cycle 25 is coming! Another new cycle sunspot, this time in the southern hemisphere has not only appeared in Earth view, but it has lingered! It even managed to fire off a couple of B-class flares before going quiet. This may be the first "real" activity that can be officially assigned to the upcoming Solar Cycle 25. In addition to this great news, we also have multiple coronal holes that have (or will be) rotating in through the Earth-strike zone this week. One of them sent strong enough fast wind our way to cause aurora clear down to Wyoming. The next burst of fast wind should hit around Monday into Tuesday. As for solar flux, its in the dumper and will continue to remain in the high 60s for the remainder of the week. This means radio propagation on Earth's dayside continues to be poor for emergency responders and amateur radio operators. However, the low solar flux and low solar activity means GPS reception on the dayside of Earth will continue to be great this week.

This episode of Space Weather News sponsored in part by 3ric Johanson: http://instagram.com/scubist Our Sun may be quiet, but Space Weather is not! This past week we had a meteor (bolide) explode over the skies near Puerto Rico in a spectacle equivalent to a 3-5 kiloton detonation! The size of this meteor was about the same as the meteor that created the new impact crater on Mars so that should give us all pause. On top of that, there is going to be a total solar eclipse over the South Pacific and South America on July 2nd. Be sure to watch your skies if you are in the region and check online, live solar telescope feeds, if you arent! If you are a radio communicator or use GPS/GNSS and are in the path of totality on July 2, you might experience some glitches in your comms or reception as the moon's shadow passes over you, so be aware. As for the weather from our star, the solar wind will likely remain disturbed over the next few days, but it should be minor. Also, some bright regions return to Earth view here in the next few days so radio propagation could bump back to the low end of marginal on Earth's dayside. Learn the details of this week's events. I have included links to the predictions of the solar corona for the eclipse from my colleagues at Predictive Science Inc. as well as links to the fantastic field reporting of the meteor blast near Puerto Rico, below.

Go to http://www.curiositystream.com/joescott to get 30 days of CuriosityStream for free. It's awesome. Do it. The sun is a solar flare machine, constantly spitting out waves of charged particles in all directions. Sometimes these hit Earth. Luckily we're protected by a strong magnetic field that directs the particles to the poles, which we experience as the Northern Lights, or Aurora Borealis. But from time to time, the sun erupts in a massive superflare, also known as a CME or Coronal Mass Ejection. These can push our magnetic shield to its limits and actually cause electrical problems on the ground. One of the worst instances of a CME striking the Earth occurred in 1859. It disrupted the telegraph system and sent sparks flying out of switchboards. It became known as the Carrington Event and begs the question - what if it happened today?

This Solar Storm Forecast sponsored in part by 3ric Johanson: http://instagram.com/scubist Two familiar bright regions rotate back into Earth-view this week, but they arent quite as active as they were the last time we saw them. No longer classified as sunspots, nevertheless, these regions are still boosting the solar flux, which means radio propagation is back into the marginal range on Earth's dayside for emergency responders and amateur radio operators. We also have a stealthy solar storm that has launched towards Earth. Couple that with the small pockets of fast solar wind in this "coronal hole, bright region oreo cookie sandwich" and we could see unsettled to active conditions on and off throughout this whole week. Learn more about how these bright regions might affect you, catch up on aurora photos from recent solar storms, and see what else our Sun has in store!

This forecast generously sponsored by: 3ric Johanson: http://www.instagram.com/scubist Our Sun dims down a bit this week as the two active regions, 2740 and 2741 rotate out of earth-view. These regions are staying active and have even fired a few solar storms on the Sun's backside. Unfortunately, this means we are back to a spotless Sun, which means poor radio propagation on Earth's dayside. These conditions will likely continue over the next week or more before things improve again. As for aurora possibilities, we do have a few small pockets of fast solar wind that will hit over the next few days that could bring unsettled and up to possibly storm conditions at high latitudes. However, aurora views are expected to be elusive, with only a small chance of views at mid-latitudes. Learn the details of the coming fast solar wind, catch up on aurora pics from last week's G1 and G3 storms, and see what else our Sun has in store!

This forecast generously sponsored by: 3ric Johanson: http://www.instagram.com/scubist The Sun gets crazy busy this week with multiple solar storms that are inbound to earth! We should feel the first of the direct hits sometime May 15 and storing should continue into May 16 and possibly through the 17th before things begin to calm down. All this rukus is due to regions 2740 and 2741 that have been firing non-sotp solar storms ever since before they even came into Earth view. Lucky for aurora photographers, they have already given us G1 and G3 level storms with aurora dipping down as far south as Wyoming and Colorado in the USA. Learn more about these regions, how they are boosting emergency and amateur radio propagation back into the marginal range, and why they could mess with your GPS reception this week!

Sarbani Basu is a Professor in the Department of Astronomy at Yale University. She is also the current Chair of the Department. Dr. Basu received her training in India, and subsequently worked in the U.K. and Denmark before moving to the US to join the Institute for Advance Study, Princeton, NJ. She has been on the faculty of Yale since 2000. Dr. Basu specializes in the study of the Sun and other stars using data on stellar oscillations (star quakes). Her past research was devoted to studying the details of the structure and dynamics of the Sun, which allowed her claim, long before the particle physics community, that the solar neutrino problem was a problem with the standard model of particle physics, not that of astrophysics. Her current research focuses on two separate topics: The first is the study of variations in the Sun over time-scales that are of societal relevance. To this end she uses solar oscillation data to examine changes that take place inside the Sun over periods of years and decades. Her second focus is to study stars, in particular exo-planet hosts, to determine their structure, age and formation histories in order to understand those systems as well as to shed light on the past and future of the Sun and the solar system. This talk was presented at the Westport Astronomical Society on April 16, 2019.

Bonus Footage: I highlight the recently confirmed Mars quake detected by the seismometer (SEIS) on the Insight Lander. This bonus segment originally aired on TMRO Space News, April 24, 2019. Space Weather picks up slightly this week as a remnant coronal hole region rotates through the Earth-strike zone. Because this region is weakening under the influence of a solar minimum Sun, expect only unsettled conditions, with aurora shows limited mostly to high latitudes. Amateur radio operators should also expect poor radio propagation this week, due to our spotless Sun, but GPS users should enjoy decent signal reception, even at low latitudes. Learn the details of the coming fast solar wind, find out when we can expect solar flux to rise again, and see what else our Sun has in store this week.

Space Weather quiets down this week though we continue to get hit with sporadic pockets of fast solar wind. Activity could increase at high latitudes, with a brief chance for aurora, but expect only unsettled conditions to persist through the remainder of this week. Aurora photographers may have difficulty catching glimpses of the aurora, but luckily that isn't the only thing in the night sky worth watching. This week, Earth enters the Lyrids meteor shower, which could give us a decent show through April 25. Skywatchers will need to get out of city lights and mind the bright, full moon on the 20th and 21st to maximize chances of seeing the spectacle. Meanwhile, back on the Sun, bright region 2738 is rotating out of view so solar flux should drop back into the low 70s by early next week. This means amateur, shortwave radio, and emergency responders will notice the drop off in communications as we fall back to poor radio propagation on Earth's dayside. However, propagation on 6m due to the Lyrids might actually pick up this week! As for GPS, users should be enjoying decent reception all around the globe easily over the next few days. Learn the details of the Lyrid shower, when solar flux will drop, and what else our Sun has in store this week.

Heliophysics is the study of the Sun, and how it influences the very nature of space — and, in turn, the atmospheres of planets and the technology that exists there. Space is not, as is often believed, completely empty; instead, we live in the extended atmosphere of an active star. Our Sun sends out a steady outpouring of particles and energy -- the solar wind – as well as a constantly writhing magnetic system. This extensive, dynamic solar atmosphere surrounds the Sun, Earth, the planets, and extends far out into the solar system. Studying this system not only helps us understand fundamental information about how the universe works, but also helps protect our technology and astronauts in space. NASA seeks knowledge of near-Earth space, because -- when extreme -- space weather can interfere with our communications, satellites and power grids. The study of the Sun and space can also teach us more about how stars contribute to the habitability of planets throughout the universe. Mapping out this interconnected system requires a holistic study of the Sun’s influence on space, Earth and other planets. NASA has a fleet of spacecraft strategically placed throughout our heliosphere -- from Parker Solar Probe at the Sun observing the very start of the solar wind, to satellites around Earth, to the farthest human-made object, Voyager, which is sending back observations on interstellar space. Each mission is positioned at a critical, well-thought out vantage point to observe and understand the flow of energy and particles throughout the solar system -- all helping us untangle the effects of the star we live with.

We are finally beginning to quiet down after exiting an extended source of sporadic fast solar wind hitting Earth over the past ten days. We may still see some storming at high latitudes, including a possibility of more aurora. However, there is only a slim chance of aurora dropping down to mid-latitudes this week. Overall, things should begin to quiet down through week's end. But we wont rest for long as another chance for a solar storm is on the horizon. Also, amateur radio and shortwave emergency responders hang on to the low end of marginal for radio propagation this week, but a new bright region will rotate into Earth view in the next few days. This new light should bump solar flux back into the mid-70s by next week, which means dayside radio propagation should improve. Luckily, this region is not a big flare producer so GPS reception should remain good on Earth's dayside. Catch up on some of the aurora photos from recent solar storms with our guest host, Kelley Filby, learn what the backside Sun reveals about the active region (old region 2733) returning into Earth view, and see what else our Sun has in store for us this week.

This week the Sun comes out of hibernation with a fast growing active region and a large coronal hole rotating into Earth view. Although the region (2733) never launched any Earth-directed solar storms, it nevertheless fired off a few C-class flares that no doubt made the HF radio bands a bit noisy. The flares may have also made GPS a bit glitchy around the dawn-dusk terminators. However, this bright active region has also boosted the solar flux back into the marginal range for radio propagation. As we say goodbye to region 2733 as it rotates to the Sun's backside, we say hello to the large coronal hole that is starting to rotate into the Earth-strike zone. Aurora photographers, especially at high latitudes should get a great show over the next few days, possibly in through the weekend. Photographers at mid-latitudes, may not be quite as lucky, but there might be a chance for some sporadic aurora starting late Thursday and into Friday. Learn the details of the activity this week, catch up on aurora photos from recent solar storming, and see what else our Sun has in store.

Our Sun is ringing in the New Year by giving us a shot at another solar storm. A triangle-shaped coronal hole is rotating into the Earth-strike zone and it promises to send us sporadic bursts of fast solar wind that could last through the end of the week. This means we could get another chance for aurora down to mid-latitudes. If that isn't enough, a new bright region has emerged on the Earth-facing Sun over the past couple of days and it has been firing some mini-solar flares. Although this region isn't a big flare producer, it has been boosting the solar flux, which has brought radio propagation is back into the marginal range on Earth's dayside. Learn how long these solar flux conditions are going to last, when we can expect the coming solar storm to hit, and whether or not GPS reception will be impacted by the Sun's activity this week.

This week we deal with more unsettled conditions as the Sun gives us a mixed bag of fast and slow solar wind streams. This means more sporadic aurora shows at high latitudes until things calm down briefly at the beginning of next week. Though the Sun is technically spotless, we have a few bright regions in Earth view that are boosting the solar flux and keeping radio propagation in the marginal range. These conditions should continue for the next few days before region 2731 dims further and rotates to the Sun's backside.

Engineers and designers working on the Parker Solar Probe tackled challenges such as size, weight, and extreme heat. Their design combined unique materials and underwent rigorous testing to transform the Probe into a record-breaking spacecraft. This Is Not a Real Explosion, Here’s How Physics Made It Happen - https://youtu.be/OsUCD4wno6g Read More Why Won't Parker Solar Probe Melt? https://www.nasa.gov/feature/goddard/2018/traveling-to-the-sun-why-won-t-parker-solar-probe-melt "In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won’t transfer much energy (low heat). Since space is mostly empty, there are very few particles that can transfer energy to the spacecraft." Who is Eugene Parker? https://www.nasa.gov/content/goddard/eugene-newman-parker "More than half a century later, the Parker Solar Probe mission will finally be able to provide key observations on Parker’s groundbreaking theories and ideas, which have informed a generation of scientists about solar physics and the magnetic fields around stars. Much of his pioneering work, which has been proven by subsequent spacecraft, defined a great deal of what we know about the how the sun–Earth system interacts." NASA Is Going to The Sun, Here’s Why That’s So Crazy https://www.seeker.com/videos/space/nasa-is-going-to-the-sun-heres-why-thats-so-crazy "From Earth, we can only ever see the corona during a total solar eclipse, which is why it is incredibly difficult to study. Because the density is so low, the corona’s brightness is overpowered by energy coming from the solar surface. As the last layer of the sun’s atmosphere, the corona extends millions of miles into space. Here, temperatures can rise to over one million degrees Celsius which is about 300 times hotter than the photosphere, the lowest layer of the sun’s atmosphere." ____________________ Science In The Extremes ventures to the ends of the earth to bring you pioneering research and innovations that are advancing our civilization and broadening our understanding of the universe.

Thanks to the hardworking Gaia spacecraft, astronomers think they’ve located a star that formed from the same solar nebula as the Sun. In fact, this star is a virtual twin of the Sun and it’s actually pretty close. Well, astronomical speaking.

Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground. ESA's future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure. ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.

The sun is the very centerpiece of our solar system and the most important source of energy for life on Earth. And according to MNN, it's on the verge of receiving a visitor. On Oct. 29, NASA's Parker Solar Probe achieved a milestone by becoming the closest man-made object to the sun. Over the next several years, the probe will orbit closer to the sun with the closest approach being 3.83 million miles away. The mission was launched to study some of the sun's biggest secrets. https://www.mnn.com/earth-matters/space/blogs/nasa-mission-solar-probe-plus-explore-sun-outer-atmosphere http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

On Sept. 22, 2006,the Japanese Aerospace Exploration Agency launched a sun-observing satellite called Hinode, or Solar-B. It was named after the Japanese word for "sunrise." The satellite orbits about 400 miles above the Earth in a sun-synchronous orbit, which means it's always facing the sun. Since it launched, it's been measuring the sun's magnetic fields and taking cool photos of solar flares, sunspots and transits across the sun.

Following years of work and preparation, a United Launch Alliance Delta IV Heavy rocket launched NASA's Parker Solar Probe for an unprecedented mission to "kiss the Sun." The spacecraft aims to unravel 60 years' worth of mysteries surrounding the Sun’s corona and how it effects life on Earth. Learn more at: http://www.nasa.gov/parkersolarprobe

Watch in 360 degrees as a United Launch Alliance Delta IV Heavy rocket lifts off from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida carrying NASA's Parker Solar Probe. Roughly the size of a small car, the spacecraft lifted off at 3:31 a.m. EDT on Aug. 12, 2018, starting its historic mission to the Sun.

The Ulysses mission revolutionized our understanding of the sun, but it's been the only orbiter to take this kind of out-of-ecliptic journey. Will an upcoming mission give us even more?

Be sure to watch to the end for a Parker Solar Probe Dedication! aurora shows, especially at high latitudes. Two coronal holes are rotating through the Earth-strike zone, which means Earth will be preconditioned for activity! The news for amateur radio operators is not so great, as the last remaining bright region on the Earth-facing Sun rotates to the Sun's backside out of view. Solar flux has dropped and we are back at poor levels for radio propagation on Earth's dayside. Unfortunately, these conditions could easily continue over the next week or more. Learn the details of the coming solar storm, see why GPS users are smiling, and why "CW" for amateur radio operators may be the mode of choice.
