Faint Glow Within Galaxy Clusters Illuminates Dark Matter
Utilizing the powerful Hubble Frontier Fields observations of galaxy clusters, a study demonstrates that intracluster light — the light of stars orphaned in galaxy cluster mergers — aligns with dark matter, tracing its distribution more accurately than other methods. With broader use, astronomers...
Hubble Takes a Close Look at the Brightest Comet of the Year
On December 13th, NASA’s Hubble Space Telescope photographed comet 46P/Wirtanen, a periodic comet that orbits the Sun once every 5.4 years. These observations were taken days before the comet’s closest approach to Earth on December 16th, when it passed just over 7 million miles from our planet....

Behind the Scenes of Recovering NASA's Hubble
In the early morning of October 27, 2018, the Hubble Space Telescope targeted a field of galaxies not far from the Great Square in the constellation Pegasus. Contained in the field were star-forming galaxies up to 11 billion light-years away. With the target in its sights, Hubble's Wide Field...
Hubble Uncovers Thousands of Globular Star Clusters Scattered Among Galaxies
Globular star clusters are favorite targets for amateur sky watchers. To the naked eye they appear as fuzzy-looking stars. Through a small telescope they resolve into glittering snowball-shaped islands of innumerable stars crowded together. About 150 globular star clusters orbit our Milky Way,...

ILLUSTRATION SHOWS LOCATION OF STAR-HUGGING EXOPLANETS
ARTIST'S ILLUSTRATION OF GAS STREAMING FROM GJ 3470B
This artist's illustration shows a giant cloud of hydrogen streaming off a warm, Neptune-sized planet just 97 light-years from Earth. The exoplanet is tiny compared to its star, a red dwarf named GJ 3470. The star's intense radiation is heating the hydrogen in the planet's upper atmosphere to a...
Celebratory Galaxy Photo Honors 25th Anniversary of NASA's First Hubble Servicing Mission
Over the past 28 years Hubble has photographed innumerable galaxies throughout the universe, near and far. But one especially photogenic galaxy located 55 million light-years away holds a special place in Hubble history. As NASA made plans to correct Hubble's blurry vision in 1993 (due to a...

Astronomers Find First Evidence of Possible Moon Outside Our Solar System
Our solar system has eight major planets, and nearly 200 moons. Though astronomers have to date found nearly 4,000 planets orbiting other stars, no moons have yet been found. That hasn't been for any lack of looking, it’s just that moons are smaller than planets and therefore harder to...
