Construction Site Ahead: Hubble Observes Planet-Forming Circumstellar Dust Disks in Great Detail

A set of high-resolution images of the vast circumstellar debris disks around 11 nearby young stars, which were obtained with the Hubble Space Telescope, have helped astronomers to study their complex and dynamic structure for the first time in great detail. This visible-light survey, called HST/GO 12228, was done with Hubble’s Space Telescope Imaging Spectrograph (STIS), […]

Intergalactic Space Is Brighter Than Thought, NASA Rocket Experiment Shows

The universe is vast and, apart from the stars and galaxies, a seemingly very dark and empty place, with utter blackness […]

Clear Skies Above: Astronomers Detect Water Vapor on Cloud-Free Atmosphere of a Hot-Neptune

Sunny and hot all year-round, with no clouds on the horizon … That’s not a weather forecast only for the Maldive […]

Astronomers Witness Asteroid Smash-Up Around Sun-Like Star

Solar systems, including ours, are thought to begin as massive clouds of dust and gas surrounding young stars; over billions of years, planets form from repeated impacts of […]

Between the Planet and the Star: A New Ultra-Cold, Sub-Stellar Object Discovered Close to Sun

Contrary to the human need for organising objects in well-defined and distinct categories, our Solar System seems to be replete with celestial objects that defy our tidy definitions […]

NASA Telescopes See ​Weather Patterns in ​Brown Dwarf​

PASADENA, Calif. — Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange […]

NASA is looking into a variety of potential uses for two of the space agency’s space-based telescopes. The […]

Life-Nurturing Asteroid Belts May Be Rare
