SPACE TELESCOPES

Join experts as we discuss the most complex telescope ever created by humans – the James Webb Space Telescope. Webb will be like a powerful time machine with infrared vision that will peer back over 13.5 billion years to see some of the first stars and galaxies forming out of the darkness of the early universe.

While we’re all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved. (Please get approved, please get approved.) We’re going to need a way to pass the time. So let’s have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes. Unless you’ve been crawling through scientific journals like me, I guarantee you’ve never heard of any of them. But when I’m done, you’re going to want to fund all of them.

A discussion of the advantages telescopes in space enjoy over telescopes on Earth. Presented by Dr. Frank Summers. This video is part of the “Cosmic Concepts” video series. It illustrates how space telescopes offer advantages to studying the universe. For example, they are above the blurring effects of Earth’s atmosphere, which affords a clearer view of the cosmos. The other major advantage of telescopes being located in space is that all wavelengths of light can be observed. An overview of NASA’s Great Observatories is provided as well.

Over its two decades in space, NASA's Chandra X-ray Observatory has captured many spectacular images of cosmic phenomena. But perhaps its most iconic is the supernova remnant called Cassiopeia A. Located about 11,000 light years from Earth, Cas A (as it's nicknamed) is the glowing debris field left behind after a massive star exploded. When the star ran out of fuel, it collapsed onto itself and rebounded explosively as a supernova, possibly briefly becoming one of the brightest objects in the sky. The shock waves generated by this blast supercharged the stellar wreckage and its environment making it glow brightly in many types of light, particularly X-rays. Shortly after Chandra was launched aboard the Space Shuttle Columbia on July 23, 1999, astronomers directed the observatory to point toward Cas A. The result was a seminal moment for the observatory and the field of X-ray astronomy with the release of Chandra's "First Light" image on August 26, 1999. Since then, Chandra has repeatedly returned to Cas A to learn more about this important object. A new movie shows the evolution of Cas A over time, enabling viewers to watch as 10-million-degree-Celsius gas in the remnant expands outward. These X-ray data have been combined with data from another of NASA's "Great Observatories," the Hubble Space Telescope, showing delicate filamentary structures of cooler gases with temperatures of about 10,000 degrees Celsius. In this movie, we see Hubble data from a single time period to emphasize the changes in the Chandra data. The movie shows Chandra observations from 2000 to 2013, or about the time it takes for a child to enter kindergarten and then graduate from high school. This gives astronomers a rare chance to watch as a cosmic object changes on human timescales, giving them new insight into the physics involved. For example, particles in the blue outer shock wave carry more energy than those produced by the most powerful particle accelerators on Earth. As this blast wave hits material in its path it slows down, sending a shock wave backwards at speeds of millions of miles per hour. Chandra will continue to observe Cassiopeia A in the future, adding to its remarkable legacy of discovery for this supernova remnant.

We have all heard of the James Webb Space Telescope but do we really understand how complex it is and how important it will be when it is put into orbit? Dr. Nathalie Ouellette explains the challenges and the dramatic advances that one of the most complex machines ever built, the James Webb Space Telescope, will have on modern astronomy. She gave her presentation at the RASC/AAVSO 2019 General Assembly on June 14, 2019 at York University.

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra's powerful and unique X-ray eyes have contributed to a revolution in our understanding of the cosmos. To commemorate Chandra's 20th anniversary of science operations, a collection of new images representing the breadth of Chandra's exploration was released. These images demonstrate the variety of objects Chandra studies as well as how X-rays complement the data collected in other types of light. Chandra is one of NASA's 'Great Observatories' along with the Hubble Space Telescope, Spitzer Space Telescope, and Compton Gamma Ray Observatory. It has the sharpest vision of any X-ray telescope ever built. Chandra is often used in conjunction with telescopes like Hubble and Spitzer that observe in different parts of the electromagnetic spectrum, and with other high-energy missions like XMM-Newton and NASA's NuSTAR. Chandra's discoveries have impacted virtually every aspect of astrophysics. For example, Chandra was involved in a direct proof of dark matter's existence. It has witnessed powerful eruptions from supermassive black holes. Astronomers have also used Chandra to map how the elements essential to life are spread from supernova explosions. Many of the phenomena Chandra now investigates were not even known when the telescope was being developed and built after first being proposed to NASA in 1976. For example, astronomers now use Chandra to study the effects of dark energy, test the impact of stellar radiation on exoplanets, and observe the outcomes of gravitational wave events. The Chandra X-ray Observatory was named in honour of the late Nobel laureate Subrahmanyan Chandrasekhar. NASA's Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science and flight operations from Cambridge, Mass. In 2018, NASA awarded a contract extension to continue operation and science support of Chandra through 2024, with the possibility of two three-year options.

This week marks the 20th launch anniversary of NASA's Chandra Space telescope, an observatory that is still observing the X-ray high energy Universe.

Scientists have found evidence that pairs of stars have been kicked out of their host galaxies. This discovery, made using data from NASA’s Chandra X-ray Observatory, is one of the clearest examples of stellar pairs being expelled from their galactic base. Astronomers use the term “binary” system to refer to pairs of stars orbiting around each other. These stellar pairs can consist of combinations of stars like our Sun, or more exotic and denser varieties such as neutron stars or even black holes. Neutron stars form when a massive star explodes as a supernova and the core of the star collapses onto itself. Under certain conditions, these gargantuan blasts that create the neutron star are not symmetric. The recoil effect can kick the star with such force that it is expelled from the galaxy where it resides. These new Chandra results show that sometimes a companion star is forced to exit the galaxy as well. How do astronomers look for these banished pairs? If the companion star is close enough, then matter from it will swirl toward the denser neutron star and form a disk around the neutron star. The strong gravitational forces from the neutron star cause the material in this disk to move more rapidly as it approaches the neutron star, and frictional forces in the disk heat the gaseous disk to tens of millions of degrees. At these temperatures, the disk glows in X-ray light. Astronomers found signatures of X-ray binaries – that is, those binaries that give off X-rays -- outside of galaxies in the Fornax galaxy cluster. They did this by studying about 15 days’ worth of Chandra data taken between 1999 and 2015. The Fornax cluster is relatively nearby at a distance of some 60 million light years from Earth in the constellation sharing its name. By combining the large Chandra dataset with optical observations, researchers made a census of X-ray sources within about 600,000 light years of the central galaxy in the Fornax cluster. Astronomers concluded that about 30 sources in the Fornax cluster were likely to be pairs of stars that had been kicked out of the center of their host galaxies. The research team hopes to look for more evicted binaries around other galaxies using Chandra in the future.

A Hubble Space Telescope color image of the core of the globular star cluster Omega Centauri is used to construct a Hertzsprung-Russell diagram of the stellar populations in the cluster. When stars are sorted by brightness and color they can be used to create a graph that astronomers use to trace stellar evolution.

This time-lapse video sequence of Hubble Space Telescope images reveals dramatic changes in a ring of material around the exploded star Supernova 1987A. The images, taken from 1994 to 2016, show the effects of a shock wave from the supernova blast smashing into the ring. The ring begins to brighten as the shock wave hits it. The ring is about one light-year across. Discovered in 1987, Supernova 1987A is the closest observed supernova to Earth since 1604. The exploded star resides 163,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of our Milky Way. Read the news release: http://hubblesite.org/news_release/news/2017-08

This visualization explores the Orion Nebula using both visible and infrared light. Two correlated computer models were created based on visible-light observations from the Hubble Space Telescope and infrared-light observations from the Spitzer Space Telescope. 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.

At the Baikonur Cosmodrome, operations began to refuel the Spektr-RG spacecraft with fuel components. The launch is scheduled for June 21, 2019. The orbital astrophysical observatory 'Spectr-RG' is designed to study the Universe in the gamma and X-ray hard energy range. The observatory will orbit in the vicinity of the Lagrange point L2 of the Sun-Earth system.

This video zooms in on the irregular galaxy NGC 4485, about 30 million light-years away. It starts with a view of the night sky focused on the constellation of Canes Venatici (The Hunting Dogs), as seen from the ground. It then zooms through observations from the Digitized Sky Survey 2, and ends with a view of the galaxy obtained with the NASA/ESA Hubble Space Telescope. During the zoom also the neighbouring galaxy, NGC 4490 becomes visible. The gravitational pull of this galaxy is responsible for the irregular shape of NGC 4485 and also caused the intense star formation in the galaxy, as well as the bright stream of gas and stars emerging from it.

NASA’s Hubble Space Telescope launched on April 24, 1990, and it’s been hard at work ever since, studying the cosmos like no other observatory in human history. Several times in its journey, astronomers have called upon Hubble to study a single spot in the sky for weeks at a time, staring as far as it can, almost to the edge of the observable Universe. These are the deep fields, including the most recent Hubble eXtreme Deep Field. Now all of these data have been mashed together into a single image, spanning more than 250 days of observations. It’s called the Hubble Legacy Field.

Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be repaired and upgraded. Astronauts using custom-designed tools performed challenging spacewalks on five servicing missions from 1993 to 2009 to keep Hubble operating so that it could change our fundamental understanding of the universe. Join John and EVA engineer Ed Rezac in this episode of Hubble Tool Time to learn about developing a wrench-like connector tool to replace Hubble’s Power Control Unit on Servicing Mission 3B in 2002. In addition to enabling Hubble's scientific discoveries, the tools developed by teams at NASA's Goddard Space Flight Center and tested in collaboration with the Johnson Space Center furthered NASA's human exploration capabilities. These tools and the knowledge gleaned from the Hubble servicing missions are used today by astronauts on the International Space Station, and will be critical to NASA's future crewed missions to the Moon and Mars.

What should we expect from the next generation of space telescopes? What key scientific questions will they help answer? Do we have the technology we need to operate them in 20-30 years? To address these issues, NASA selected four large space mission concepts to study and consider as possible future Large Strategic Science Missions. Of the NASA astrophysics division missions, these tend to be the most expensive, but also have the greatest capacity. Three of those space telescopes got the attention of the SETI Institute because of their potential to answer the question, “Are We Alone?” The Origins Space Telescope (Origins) is a large cooled infrared space telescope with higher sensitivity and better angular resolution than any prior observatory accessing similar wavelengths. Among its many science objectives covering the first stars to life, Origins could help scientists understand the abundance and availability of water for habitable planets and could look forbiosignatures on potentially habitable worlds transiting low-mass stars. The Large UV Optical Infrared Surveyor (or LUVOIR) is a general-purpose observatory; its key science goal is to characterize a wide range of exoplanets, including those that might be habitable and orbiting a range of stellar types. The Habitable Exoplanet Imaging Mission (HabEx) is a space telescope, optimized to search for and image Earth-sized exoplanets in the habitable zones around sun-like stars, where liquid water might exist. HabEx would also have a suite of general astrophysics science capabilities. Each of these concepts has pros and cons, as well as other technological, cost, and risk challenges. These mission concepts will be described in detail in their final study reports, which will be delivered to the National Academy of Sciences for the Astro 2020 Decadal Survey later this year. It is still unknown whether the Decadal Survey will prioritize none, one, or even all of these concepts, but the several hundred scientists and engineers involved in these mission concept studies for the past three years are confident that we are now capable of building these telescopes, and that the science that they can deliver will be compelling and change again our view of the cosmos, just as the Hubble Space Telescope has done for the past 3 decades. We invited three scientists directly involved in each one of the three teams above to discuss these exciting future mission projects. During this SETI Talk, they will describe their projects, and tell us more about the challenges and the processes that could make these missions a reality: Prof. Courtney Dressing, astronomer and member of the LUVOIR Science and Technology Definition Team (STDT), whose research aims to detect and characterize planetary systems orbiting nearby stars. Dr. Kimberly Ennico Smith, a NASA research astrophysicist who is multidisciplinary in her approach to space instruments, telescopes, and mission concepts. She is a member of the STDT of OST. Prof. Scott Gaudi, astronomer and community chair of the HabEx STDT, who bridges the gap between theory and observations, with extensive experience in leadership roles and consensus-building, as well as experience with several exoplanet detection methods and exoplanet surveys.

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

A ricocheting jet blasting from a giant black hole has been captured by NASA's Chandra X-ray Observatory. Chandra's data reveal the presence of a powerful jet of particles and electromagnetic energy that has shot out from the black hole and slammed into a wall of hot gas, then ricocheted to punch a hole in a cloud of energetic particles, before it collides with another part of the gas wall. Cygnus A is a large galaxy that sits in the middle of a cluster of galaxies about 760 million light years from Earth. A supermassive black hole at the center of Cygnus A is rapidly growing as it pulls material swirling around it into its gravitational grasp. During this process, some of this material is redirected away from the black hole in the form of a narrow beam, or jet. Such jets can significantly affect how the galaxy and its surroundings evolve. In a deep observation that lasted 23 days, scientists used Chandra to create a highly detailed map of both the jet and the intergalactic gas, which they used to track the path of the jets from the black hole. The jet expanded after ricocheting and created a hole in a nearby cloud of particles that is between 50,000 and 100,000 light years deep and 26,000 light years wide. For context, the Earth is located about 26,000 light years away from the center of the Milky Way galaxy. Energy produced by jets from black holes can heat intergalactic gas in galaxy clusters and prevent it from cooling and forming large numbers of stars in a central galaxy like Cygnus A. By studying Cygnus A, scientists can tell more about how jets from black holes interact with their surroundings.

In a galaxy about 290 million light years from Earth, a star wandered too close to a black hole. The immense gravitational forces of the black hole shredded the star, sending the stellar remains into orbit around it. Scientists used several telescopes including NASA's Chandra X-ray Observatory to study this "tidal disruption" event called ASASSN-14li. They were able to use the data to measure the spin of the giant black hole at the center of the galaxy containing ASASSN-14li. The scientists determined that the black hole in ASASSN-14li is spinning incredibly quickly — about half as fast as the speed of light or faster. Since the spins of black holes have been difficult to measure, this discovery is exciting for astronomers.

In November 2014, a network of optical telescopes picked up a bright outburst from a galaxy about 290 million light years from Earth. Scientists determined that this was a so-called tidal disruption event, where a star wandered too close to a black hole and was ripped apart by immense gravitational forces. Astronomers used other telescopes including a flotilla of high-energy telescopes in space — NASA's Chandra X-ray Observatory, ESA's XMM-Newton and NASA's Neil Gehrels Swift observatory — to study the X-rays emitted as the remains of a star swirled toward the black hole at the center of the galaxy. Some of the remains of the star are pulled into a disk where they circle the black hole before passing over the "event horizon," the boundary beyond which nothing, including light, can escape. The tidal disruption in ASASSN-14li allowed astronomers to estimate the spin rate of the black hole. A black hole has two fundamental properties: mass and spin. While it has been relatively easy for astronomers to determine the mass of black holes, it has been much more difficult to get accurate measurements of their spins. This debris from the shredded star gave astronomers an avenue to directly estimate the black hole's spin in ASASSN-14li. They found that the event horizon around this black hole is about 300 times the diameter of the Earth, yet rotates once every two minutes (compared to the 24 hours it takes to complete one rotation). This means that the black hole is spinning at least about half as fast as the speed of light. These results will likely encourage astronomers to observe future tidal disruption events for long durations to look for similar, regular variations in their X-ray brightness.

Black holes are notorious for pulling things toward them. But in some cases, black holes can act as powerful engines to blast material away. One of those black holes is found in Cygnus A, a large galaxy embedded within in a cluster of galaxies. Cygnus A's black hole is blasting a jet — a tightly-wound column of material — away from it at extremely high speeds. Astronomers found that his jet ricocheted off a wall of hot gas, then punched a hole in a cloud of energetic particles, leaving behind a gigantic hole. By studying this kind of behavior, scientists can better understand how black holes affect their surroundings. Only an X-ray telescope with the sharp vision of NASA's Chandra X-ray Observatory could make such a discovery.

The AKARI satellite discovered water in 17 asteroids in the form of hydrated minerals for the first time.

Kepler was NASA’s first mission dedicated to the search for planets around other stars, called exoplanets. The first exoplanet was discovered just 20 years prior to launch, and only a few hundred more were discovered in that time, with most of them inhabitable and more similar to gas giants like Jupiter than Earth. In the nearly ten years since Kepler’s launch, data from the spacecraft has resulted in the detection of thousands of exoplanets, with a multitude of them the size of Earth or smaller, and many of them at the right distance from their star to possibly support life. Thanks to data from Kepler, we now have greater understanding of two terms of the Drake Equation that had eluded us for fifty-seven years --- we now know there are even more planets than stars in our galaxy and that a significant number of them could have the right conditions to be habitable. Thanks to Kepler, we know that Earth is not alone. The odds of humanity not being alone in the cosmos seem high. But there are still a lot of big terms in that simple little Drake Equation to figure out. The search will continue with new space telescopes like TESS (Transiting Exoplanet Survey Satellite), and future generation of large space telescopes like JWST (James Webb Space Telescope). We invited Natalie Batalha, Professor at U.C. Santa Cruz, and Doug Caldwell, Senior Research Scientist at the SETI Institute to discuss the state of the search for exoplanets. What did we learn from the Kepler mission? What are the most exotic planetary systems discovered so far? What are the chances of finding extraterrestrial life in the next decade using new telescopes? These are the questions that will be addressed during our special SETI Talk on the end of the Kepler spacecraft on November 13 at 7pm at SRI International, Menlo Park, CA. Join us for a special tribute to the Kepler spacecraft.

With NASA's Kepler being retired, is this the end of exoplanet hunting? Thankfully, no it isn't! NASA has just launched TESS, and we will soon be getting the James Webb Space telescope and ESA's Plato.
