HUBBLE SPACE TELESCOPE

The Hubble Space Telescope created a giant mosaic image of the Triangulum Galaxy (M33) at the 233rd meeting of the American Astronomical Society. It's the highest-resolution image of Triangulum galaxy ever created, resolving more than 15 million individual stars. Triangulum is the third-largest galaxy in the Local Group of galaxies, which include the Andromeda galaxy, the Milky Way galaxy, and about 50 dwarf galaxies. Hubble made a similar mosaic of the Andromeda galaxy in 2015. These Hubble mosaics, combined with similar studies of the Milky Way and Magellanic Clouds, will allow astronomers to better understand stellar evolution both locally and throughout the universe. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 Share this video with a fellow space traveler: https://youtu.be/8h_QZN6bxrc 🔴 Watch my most recent upload: https://youtu.be/kCpqlLeGSS4 🚀 Join the Launch Pad community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you.

According to a report by Gizmodo, the NASA team behind the Hubble Space Telescope has temporarily suspended operations of Wide Field Camera 3 following a hardware glitch. NASA's Hubble Twitter account reportedly first tweeted about the instrument failure on Tuesday, saying only that there had been a hardware problem. Gizmodo reports that this is the second notable hardware problem that has shutdown operations for Hubble in just the last few months. This most recent glitch reportedly comes on the heels of another back in October when a gyroscope, one of six that monitor the telescope’s position and motion, failed. https://gizmodo.com/hubble-space-telescope-faces-more-hardware-trouble-1831636773 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years.

This video pans over NASA/ESA Hubble Space Telescope observations of the Serpens Nebula, about 1300 light-years from Earth. It is a reflection nebula that owes most of its sheen to the light emitted by stars in its surroundings or embedded within it. It is also home to two cosmic shadows, created by stars which are orbited by protoplanetary discs.

To change its orientation and to correct for drifts Hubble does not use propellants. Their fumes could contaminate Hubble’s observations and limit its lifetime. Instead, Reaction Wheels steer the telescope, using the elegant principle of Newton’s third law: if one of the wheels turns clockwise, Hubble will turn counterclockwise. This animations shows two reaction wheels, like the ones installed in the NASA/ESA Hubble Space Telescope.

The Hubble Space Telescope is back in business after the operations team managed to fix a faulty gyroscope by "shaking" the telescope. And the Chandra X-Ray Observatory also returned to science operations following a glitch in one of its gyroscopes. 🔴 Subscribe to my channel: https://www.youtube.com/christianready?sub_confirmation=1 🔴 Support Launch Pad on Patreon! https://www.patreon.com/launchpadastro 🔴 Share this video with a friend: https://youtu.be/hmPLaYSyDu4 🔴 From out of town?

According to Mother Nature Network, NASA fixed a problem with the Hubble telescope by performing a maneuver. The trick to fix a malfunctioning gyroscope involved maneuvering the telescope to jiggle the problematic part loose. Earlier this month, the Hubble Space Telescope entered a 'safe mode' after one of its three gyroscopes seized up. Since gyroscopes help the Hubble maintain an orbit, they are critical components, providing NASA engineers with an imperative to find a solution quickly. Fortunately, the Hubble operations team performed a series of sharp turns, while switching the gyro from high to low, which did the trick. https://www.mnn.com/earth-matters/space/blogs/nasa-fixes-hubble-telescope-jiggle-maneuver http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

The Hubble Space Telescope has given us some of the most amazing views of the universe for 25 years and although it could go on for many years more, things are starting to go wrong but without the shuttle, we have no real way the fix it. But its successor the James Webb Space Telescope was due to have been in space years ago. However, now it isn't due to launch until 2021, so could we save Hubble and why is the JWST taking so long.

The mission engineers and scientists for the Hubble Space Telescope have been working to correct some technical issues with the gyros that point the venerable space telescope. Hubble went into safe mode a couple of weeks ago and now seems to be back to resuming normal operations. Join Tony Darnell and Carol Christian as they discuss what happened with Hubble, how the problems were discovered and a fix found. We'll also explore other topics related to Hubble, such as, how much longer will it be around? Will Hubble last long enough to overlap JWST? Like this content?

How Hubble points is a really interesting question. Instead of thrusters, Hubble uses a sophisticated system of reaction wheels and magnetic torque rods (magnetorquers) to point itself from one target to the next. Hubble also uses rate sensing gyroscopes (gyros), fixed head star trackers (FHST), Sun sensors, magnetometers, and three fine guidance sensors (FGS) that allow Hubble to maintain ultra-steady pointing on a target for up to 24 hours at a time! 🔴 Subscribe to my channel: https://www.youtube.com/christianready?sub_confirmation=1 🔴 Share this video with a friend: https://youtu.be/qEZI9DxIQss 🔴 From out of town?

Hubble Space Telescope update on the effort to recover its flaky backup gyro. Meanwhile, the Chandra X-Ray Observatory went into safe mode on Oct 10, and the Kepler Space Telescope is almost out of fuel.

Is the Hubble Space Telescope dead? No, but Hubble is in trouble. It lost one of the three gyros it needs to point and maintain its pointing during science operations. Hubble is in safe mode and engineers are working to determine the best course of action. Chances are HST may go to a single gyro mode, which would keep Hubble operational a little longer, but it may have to change the way it goes about its business. 🔴 Subscribe to my channel: https://www.youtube.com/christianready?sub_confirmation=1 🔴 Share this video with a friend: https://youtu.be/NCuzKYU7tuQ 🔴 From out of town?

Bad news I’m afraid for the venerable Hubble Space Telescope. Project Scientists tweeted earlier today that Hubble has been placed in safe mode as two of it’s critical gyros used for pointing have failed. As sad as it is, it appears that the clock is ticking on this 28 year old masterpiece.

Alex Teachey is the first author of our new paper presenting compelling evidence for an exomoon orbiting Kepler-1625b. The embargo on our paper in Science Advances has just lifted and we wanted to give our viewers a Cool Worlds exclusive! In one two videos we've shot, Alex goes through our new observations of Kepler-1625b using the Hubble Space Telescope and explains why we think the exomoon hypothesis is the most viable hypothesis to explain this new data, yet why we still think it's best to think of this as a candidate rather than a discovery. ► Companion Video by David Kipping: https://youtu.be/vlcc2MdYaik ► "Did we find an exomoon?" earlier video on Kepler-1625: https://youtu.be/8V9QHn5oHMs ► "An Update on our Exomoon Candidate" earlier video: https://youtu.be/vDXJAtLLiyw == Referenced papers == ► Teachey, A. & Kipping, D., 2018, "Evidence for an Exomoon Orbiting Kepler-1625b", Science Advances ► Teachey, A., Kipping, D. & Schmitt, A., 2018, "HEK.

An international team of astronomers using Hubble has made the most precise test of general relativity yet outside our Milky Way. A nearby galaxy acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of the lensing galaxy with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.

This animation shows the Messier 101 (Pinwheel) Galaxy, with simulated rotation, in visible, then infrared, then X-ray, and finally all three combined. M101 is a comparable in size to the Milky Way. The disk is 100 billion solar masses, and the central bulge of about 3 billion solar masses. M101 is rich is pinkish star forming regions, many of which are very large and bright. Unlike most spiral galaxies, M101spiral shape is notably asymmetrical. This is due to the tidal forces from interactions with its companion galaxies. These gravitational interactions compress interstellar hydrogen gas, which then triggers strong star formation activity in M101's spiral arms. Video Credit: NASA, ESA, and G.

30 Doradus (the Tarantula Nebula) is a very bright and active star-forming region outside of the Milky Way galaxy, at 160,000 light-years away. “30 Dor” is home to the central star cluster NGC 2070, including the most active region, R136, which appears in the central-right area of the image. R136 is a few million years old and contains many thousands of young stars, including several of the largest known. The bright blue stars shine out of the cleared cavity that is excavated by stellar winds. The redder stars are still partially embedded in the cloud material, seen in shadow except where illuminated by the cavity stars. In the infrared view the embedded stars shine more clearly through the intervening cloud material. Video Credit: NASA, ESA, G.Bacon (STScI) Image Credit: NASA, ESA, F.

360 Video - Use the mouse to scroll the view on a computer. For full immersion, watch using a virtual reality device and a 360 video player. This visualization explores the Orion Nebula using both visible-light observations from the Hubble Space Telescope and infrared-light observations from the Spitzer Space Telescope. The contrast between visible and infrared views of the nebula are examined using two spatially matched three-dimensional models. As the camera flies into the star-forming region, the sequence cross-fades back and forth between the visible and infrared views. The glowing gaseous landscape has been illuminated and carved by the high-energy radiation and strong stellar winds from the massive hot stars in the central cluster. The infrared observations generally show cooler temperature gas at a deeper layer of the nebula that extends well beyond the visible image. In addition, the infrared showcases many faint stars that shine primarily at longer wavelengths. The higher resolution visible observations show finer details including the wispy bow shocks and tadpole-shaped proplyds. In this manner, the movie illustrates the contrasting features uncovered by multi-wavelength astronomy. Credits: NASA, ESA, F. Summers, G. Bacon, Z. Levay, J. DePasquale, L. Hustak, L. Frattare, M.

Gravitational Wave Astronomy Andrew Fruchter, Space Telescope Science Institute The 2017 Nobel Prize in Physics was awarded for the observation of gravitational waves. This new field transforms our ability to study the universe. For the first time, we can directly observe the mergers of binaries composed of the densest macroscopic objects in the universe—black holes and neutron stars. The results are revolutionary. We have discovered stellar mass black holes far larger than any previously known, and have seen them merge to form even larger black holes. We have seen evidence that neutron star mergers are a major source of the heavy elements in the universe. Dr. Fruchter will provide an introduction to the technology and physics behind the detection of gravitational waves as well as discuss the exciting new results.

This video zooms into the core of a rich star-birth region called the Lagoon Nebula, located in the constellation Sagittarius in the direction of our Milky Way galaxy’s central bulge. The sequence then dissolves to a series of imagined three-dimensional flights past striking structures of this gaseous landscape. Viewers examine dark, dusty clouds silhouetted against a colorful background of luminous gas that has been heated by a massive star. Pillars of dense gas and bow shocks around newborn stars are shaped by the strong winds from the brightest stars. The intense high-energy emission from these same stars creates the glowing ridges of gas in ionization fronts. These features are some of the highlights of this vibrant region where new stars and planets are born. Credit: NASA, ESA, and G. Bacon, D. Player, J. DePasquale, F. Summers, and Z.

More space news and info at: http://www.coconutsciencelab.com - on April 24, 1990 Hubble was launched into space. To celebrate its 28th year in orbit, some of Hubble’s precious observation time was used to observe the colorful Lagoon Nebula. One of only two star-forming nebulae visible to the unaided eye, this spectacular stellar nursery is not quite the tranquil landscape its name suggests. This new Hubblecast explores the image in more detail and shows some of the delicate features of this cosmic lagoon. Please rate and comment, thanks!

Mapping the United Federation of Planets: An Astronomer's Guide to the Galaxy Mia Bovill, Space Telescope Science Institute How big is Star Trek's United Federation of Planets? How far did the various starship captains travel? Where exactly are the Klingons? To answer these questions, we need to leave the future spacefaring of the Enterprise behind and ask questions of astronomers in the here and now of 21st century Earth. Where is the Earth located within our Milky Way? What are the overall shape and scale of the galaxy? And just how can we decipher the Milky Way's features when we are stuck at one location inside it? Come for the Star Trek, and stay to hear the centuries long, ongoing, and arduous tale of how a "minor bipedal species" is mapping the Milky Way.

Worlds in the Star’s Habitable Zone Are Not Smothered Under Primordial Atmospheres Only 40 light-years away — a stone’s throw on the scale of our galaxy — several Earth-sized planets orbit the red dwarf star TRAPPIST-1. Four of the planets lie in the star’s habitable zone, a region at a distance from the star where liquid water, the key to life as we know it, could exist on the planets’ surfaces. Astronomers using NASA's Hubble Space Telescope have conducted the first spectroscopic survey of these worlds. Hubble reveals that at least three of the exoplanets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. This means the atmospheres may be more shallow and rich in heavier gases like those found in Earth’s atmosphere, such as carbon dioxide, methane, and oxygen. Astronomers plan to use NASA’s James Webb Space Telescope, scheduled to launch in 2019, to probe deeper into the planetary atmospheres to search for the presence of such elements that could offer hints of whether these far-flung worlds are habitable.
