Hubble Finds First Evidence of Water Vapor at Jupiter's Moon Ganymede

Located ½-billion miles from the Sun, the water ice on Ganymede's surface is frozen solid in frigid temperatures as low as minus 300 degrees Fahrenheit. This makes the ice as hard as rock. Still, a rain of charged particles from the Sun is enough...

NASA’s Webb to Explore a Neighboring, Dusty Planetary System

Planetary systems are very busy places. In addition to the planets orbiting their host star, planetary systems are chock full of dust and other fragments left over from planet formation – a debris disk. Our own solar system includes the Kuiper...

NASA’s Webb Will Use Quasars to Unlock the Secrets of the Early Universe

Outshining all the stars in their host galaxies combined, quasars are among the brightest objects in the universe. These brilliant, distant and active supermassive black holes shape the galaxies in which they reside. Shortly after its launch,...

Mystery of Galaxy's Missing Dark Matter Deepens

Hubble astronomers say they confirmed that an oddball galaxy mysteriously lacks dark matter—the glue that holds stars and gas together in galaxies. This confirmation challenges the standard ideas of how researchers think galaxies work.

Astronomers Probe Layer-Cake Structure of Brown Dwarf’s Atmosphere

Researchers used the giant W. M. Keck Observatory in Hawaii to observe a nearby brown dwarf in infrared light. They found that the dwarf’s atmosphere has a layer-cake structure with clouds of different composition at different altitudes.

Lopsided Galaxy NGC 2276

The magnificent spiral galaxy NGC 2276 looks a bit lopsided in this Hubble Space Telescope snapshot. A bright hub of older yellowish stars normally lies directly in the center of most spiral galaxies. But the bulge in NGC 2276 looks offset to the...

Space Telescope Science Institute (STScI): Nearly 400 years after Galileo first observed the heavens through a telescope, we continue to seek answers to age-old questions about the universe. And while the technology has evolved over the centuries, the inquiry remains essentially the same: What's out there, where did it come from, and what does it mean?

At the Space Telescope Science Institute (STScI), we're working hard to study and explain the once-unimaginable celestial phenomena now made visible using Hubble's cutting-edge technology. In the course of this exploration we will continue to share with you the grace and beauty of the universe, because the discoveries belong to all of us.
