Hubble Detects Smallest Known Dark Matter Clumps

Using Hubble and a new observing technique, astronomers have uncovered the smallest clumps of dark matter ever detected. Dark matter is an invisible substance that makes up most of the universe's mass and forms the scaffolding upon which galaxies...

Cosmic Magnifying Glasses Yield Independent Measure of Universe's Expansion

Astronomers using Hubble have made the most precise measurement yet of the universe’s expansion rate using the gravitational lensing method, which is independent from the usual cosmic distance ladder.

Goldilocks Stars Are Best Places to Look for Life

Hubble observations suggest that orange stars, slightly cooler than our Sun, are better hangouts for life. There are more of them in our galaxy, they live much longer than our Sun, and unleash less deadly radiation than red dwarf stars.

NASA's Hubble Surveys Gigantic Galaxy

Hubble has photographed a majestic spiral galaxy, UGC 2885, located 232 million light-years away. The galaxy is 2.5 times wider than our Milky Way and contains 10 times as many stars. Astronomers want to know how it got so big.

NASA's Great Observatories Help Astronomers Build a 3D Visualization of Exploded Star

Astronomers and visualization specialists have combined the visible, infrared and X-ray vision of NASA's Great Observatories to create a 3D representation of the dynamic Crab Nebula—the tattered remains of an exploded star.

Simulated Image Demonstrates the Power of NASA’s Wide Field Infrared Survey Telescope

NASA’s upcoming Wide Field Infrared Survey Telescope (WFIRST), scheduled for launch in the mid-2020s, will have the power to survey the sky 1,000 times faster than the Hubble Space Telescope, with Hubble-quality detail, in the near-infrared.

'Cotton Candy' Planet Mysteries Unravel in New Hubble Observations

Astronomers using Hubble have studied a unique class of young, migratory exoplanets that have the density of cotton candy. Nothing like them exists in our solar system. They orbit the star Kepler 51, located 2,600 light-years away. Hubble...

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.
