The operations people behind the Space Telescope’s 30 years of breakthrough science are honored by the National Air and Space Museum.
Hubble Space Telescope observations suggest that the broad “brim” of the Sombrero galaxy may conceal a turbulent past. Clues to a rough-and tumble history lie in the galaxy’s extended halo.
The TRAPPIST-1 system of exoplanets holds exciting possibilities in the search for potentially habitable worlds. In this system an ultra-cool star is orbited by seven rocky, Earth-sized worlds, three of which are in the “Goldilocks” zone where liquid w…
Astronomers searching archival data from NASA’s Kepler exoplanet hunting mission identified a previously unknown dwarf nova that underwent a super-outburst, brightening by a factor of 1,600 times in less than a day.
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.
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.
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 …
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.
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.
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.
