Newswise: Hubble Detects Smallest Known Dark Matter Clumps

Hubble Detects Smallest Known Dark Matter Clumps

Space Telescope Science Institute (STScI)

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 are built.

Cosmic Magnifying Glasses Yield Independent Measure of Universe's Expansion

Space Telescope Science Institute (STScI)

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.

Newswise: Goldilocks Stars Are Best Places to Look for Life

Goldilocks Stars Are Best Places to Look for Life

Space Telescope Science Institute (STScI)

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

Space Telescope Science Institute (STScI)

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.

The Turbulent Life of Two Supermassive Black Holes Caught in a Galaxy Crash

National Radio Astronomy Observatory

An international team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to create the most detailed image yet of the gas surrounding two supermassive black holes in a merging galaxy.

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

Space Telescope Science Institute (STScI)

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.
