Identifying liquid water on other worlds, big or small, is crucial in the search for habitable planets beyond Earth. Though the presence of an ocean on Ganymede has been long predicted based on theoretical models, NASA's Hubble Space Telescope found the best evidence for it. Hubble was used to watch aurorae glowing above the moon's icy surface. The aurorae are tied to the moon's magnetic field, which descends right down to Ganymede's core. A saline ocean would influence the dynamics of the magnetic field as it interacts with Jupiter's own immense magnetic field, which engulfs Ganymede. Because telescopes can't look inside planets or moons, tracing the magnetic field through aurorae is a unique way to probe the interior of another world.

Astronomers using NASA's Hubble Space Telescope have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies. The team's science paper will appear on March 6 in a special issue of the journal Science celebrating the centenary of Albert Einstein's Theory of General Relativity. Join Hubble astronomers during the live Hubble Hangout discussion at 3pm EST on Thurs., March 5, to learn still more. Visit https://www.youtube.com/watch?v=5eQTUK6XvB8 .

This Hubble Space Telescope photograph of an oddball arc of stars in galaxy NGC 7714 tells of a 100-million-year-old close encounter.
In celebration of its 25th anniversary, NASA's Hubble Space Telescope has revisited the famous "Pillars of Creation" region of the Eagle Nebula (M16), providing astronomers with a sharper and wider view. As a bonus, the pillars have been photographed in near-infrared light, as well as visible light.
The largest NASA Hubble Space Telescope image ever assembled, this sweeping view of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long section of the galaxy's pancake-shaped disk.
At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.
The Space Telescope Science Institute (STScI) in Baltimore, Maryland, has appointed Dr. Roeland van der Marel to lead its work on a proposed NASA space telescope that will provide images as sharp as the Hubble Space Telescope, but over a hundred times larger area. The space observatory, called the Wide-Field Infrared Survey Telescope-Astrophysics Focused Telescope Assets (WFIRST-AFTA), is being studied for launch in the mid-2020s, pending program approval by NASA.
NASA's Hubble Space Telescope has uncovered young, massive, compact galaxies whose raucous star-making parties are ending early. The firestorm of star birth has blasted out most of the remaining gaseous fuel needed to make future generations of stars. Now the party's over for these gas-starved galaxies, and they are on track to possibly becoming so- called "red and dead galaxies," composed only of aging stars. An analysis of 12 merging galaxies is suggesting that energy from the star-birthing frenzy created powerful winds that are blowing out the gas, squelching future generations of stars. This activity occurred when the universe was half its current age of 13.7 billion years.
Over the past few years, astronomers have found an incredible diversity in the architecture of exoplanetary systems, as well as the planets themselves. A survey using the sharp view of the Hubble Space Telescope has uncovered a similar diversity in the debris systems that coincide with the formation of exoplanets. These circumstellar dusty disks are likely generated by collisions between objects left over from planet formation around stars. The survey's results suggest that there is some sort of interdependence between a planet and the accompanying debris system.
The universe is an infinite sea of galaxies, which are majestic star-cities. When galaxies group together in massive clusters, some of them can be ripped apart by the gravitational tug of other galaxies. Astronomers using the Hubble Space Telescope to probe the massive galaxy cluster Abell 2744 — nicknamed Pandora's Cluster — have found forensic evidence of galaxies torn apart long ago. It's in the form of a phantom-like faint glow filling the space between the galaxies. This glow comes from stars scattered into intergalactic space as a result of a galaxy's disintegration.
On April 21, 2014, the Hubble Space Telescope captured an image of what appears to be Jupiter "looking back at Earth," as the shadow of the Jovian moon Ganymede passed over Jupiter's Great Red Spot.
A composite Hubble Space Telescope image provides the position of comet Siding Spring during the comet's closest approach to Mars on October 19, 2014. Join Hubble astronomers for a live discussion at 3pm today during the Comet Siding Spring/Mars Hubble Hangout at https://plus.google.com/u/0/events/cq3l54o0if0solg51h5tocbf508.
Using the Hubble Space Telescope and the lensing power of giant galaxy cluster Abell 2744, astronomers may have made the most reliable distance measurement yet of an object that existed in the very early universe. The galaxy, estimated to be over 13 billion light-years away, is one of the farthest, faintest, and smallest galaxies ever seen.
NASA's Hubble Space Telescope has uncovered three Kuiper Belt objects that the agency's New Horizons spacecraft could potentially visit after it flies by Pluto in July 2015.
A team of scientists using the Hubble Space Telescope has made the most detailed map yet of the temperature of an exoplanet’s atmosphere and traced the amount of water it contains. The planet targeted for both of the investigations was the hot-Jupiter exoplanet WASP-43b.
Astronomers using the Hubble, Spitzer, and Kepler space telescopes were able to determine that the exoplanet, cataloged HAT-P-11b, has clear skies and steamy water vapor in its atmosphere. The planet is about the size of Neptune. The results will appear in the online version of the journal Nature on 24 September 2014.
Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known. The black hole is five times the mass of the one at the center of our Milky Way galaxy.
Using NASA’s Hubble Space Telescope, astronomers have discovered a companion star to a rare class of supernova, known as a Type IIb. The discovery confirms a long-held theory that the supernova, dubbed SN 1993J, occurred inside what is called a binary system, where two interacting stars caused a cosmic explosion.

Free for download from Apple's iBooks Store, this iBook textbook was created for iPad by analytics provider SAS and STScI.
The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Astronomers identified a dense galactic core, dubbed "Sparky," using a combination of data from Hubble and Spitzer, other space telescopes, and the W.M. Keck Observatory in Hawaii. Hubble photographed the emerging galaxy as it looked 11 billion years ago, just 3 billion years after the birth of our universe in the big bang.
Using NASA's Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a "zombie star" after an unusually weak supernova explosion.
Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record holder by 200 million years.
Astronomers using NASA's Hubble Space Telescope have found that bloated hot Jupiters have less water vapor than predicted.
NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light-years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen process.
Planetary scientists have successfully used the Hubble Space Telescope to find two Kuiper Belt objects for NASA's New Horizons mission to Pluto. After the marathon probe zooms past Pluto in July 2015, it will travel across the Kuiper Belt -- a vast rim of primitive ice bodies left over from the birth of our solar system 4.6 billion years ago. If NASA approves, the probe could be redirected to fly to a Kuiper Belt object and photograph it up close.
An international team of astronomers using data from several NASA and (ESA) space observatories has discovered unexpected behavior from the supermassive black hole at the heart of the galaxy NGC 5548. Their findings may provide new insights into the interactions of supermassive black holes and their host galaxies.
New observations from NASA's Hubble Space Telescope show that small galaxies, also known as dwarf galaxies, are responsible for forming a large proportion of the universe's stars.
NASA's Hubble Space Telescope will be used to search for a suitable Kuiper Belt object that NASA's New Horizons space probe could visit. It would be our first and perhaps last look at such a remote relic from the distant past. The search is very challenging even for Hubble's sharp vision. It has to find something the size of Manhattan Island, as black as charcoal, and embedded against a snowstorm of background stars.
Astronomers using the Hubble Space Telescope have assembled a comprehensive picture of the evolving universe — among the most colorful deep space images ever captured by the 24-year-old telescope. This study, which includes ultraviolet light, provides the missing link in star formation.
On Wednesday May 21, a panel of leading experts in astrophysics and astronomy will describe the scientific and technological roadmap for discovering habitable worlds among the stars. The panel, entitled "The Search for Life in the Universe," is part of the 30th Space Symposium to be held in Colorado Springs, Colorado, May 19 to 22.
Recent Hubble observations confirm that Jupiter's Great Red Spot, a swirling storm feature larger than Earth, has shrunken to the smallest size astronomers have ever measured. Join Hubble astronomers for further discussion about Jupiter's shrinking Great Red Spot at 4pm EDT on Thursday, May 22, at https://www.youtube.com/watch?v=9coSaxpQ8DQ. Please bring your questions and comments.
Two teams of astronomers using the NASA's Hubble Space Telescope have discovered three distant exploding stars that have been magnified by the immense gravity of foreground galaxy clusters, which act like "cosmic lenses." These supernovae offer astronomers a powerful tool to check the prescription of these massive lenses, and may be the next best thing to a giant cosmic eye chart.
Astronomers using NASA's Hubble Space Telescope have applied a new image processing technique to obtain near-infrared scattered light images of five disks in images of young stars in the Mikulski Archive for Space Telescopes database. These disks are telltale evidence for newly formed planets.
During the four-day symposium "Habitable Worlds Across Time and Space," scientists from diverse fields will gather at the Space Telescope Science Institute (STScI) in Baltimore, Md., on April 28 to May 1 to discuss the formation and long-term evolution of terrestrial bodies throughout the various phases of stellar and Galactic evolution. A special Science Writers Workshop will be held at the conclusion of the Symposium on May 1.
Astronomers using NASA's Hubble Space Telescope have weighed the largest known galaxy cluster in the distant universe and found that it definitely lives up to its nickname: El Gordo (Spanish for "the fat one").
NASA and STScI have announced the selection of 17 new Hubble Fellows. STScI administers the Hubble Fellowship Program for NASA. The Hubble Fellowship Program includes all research relevant to present and future missions in NASA's Cosmic Origins theme, which includes Herschel, Hubble, the Webb telescope, SOFIA, and Spitzer. The new Hubble Fellows will begin their programs in the fall of 2014.
This is a Hubble Space Telescope picture of comet C/2013 A1 Siding Spring as observed on March 11, 2014. At that time the comet was 353 million miles from Earth. While analyzing this Hubble data, astronomers detected two jets of dust coming off the comet's nucleus in opposite directions.
Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. According to their analysis, the central part of the neighboring galaxy, called the Large Magellanic Cloud (LMC), completes a rotation every 250 million years.
Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world called Kepler-413b found by NASA's planet-hunting Kepler space telescope.
Astronomers using NASA's Hubble and Spitzer space telescopes, Europe's Herschel Space Observatory, and numerous ground-based telescopes have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe.
Michael Hauser, former deputy director of the Space Telescope Science Institute and an adjunct professor in the Johns Hopkins University's Physics and Astronomy Department, will receive the 2014 George Van Biesbroeck Prize from the American Astronomical Society.
