Surprisingly Bright Cloud Systems and Extreme Storms on Uranus Puzzle Astronomers

Infrared images of Uranus at wavelengths of 1.6 (left) and 2.2 microns (right), that were obtained on Aug. 6, with the Adaptive Optics system on the 10-meter Keck II telescope on Mauna Kea in Hawaii. The white spot is an extremely large storm that was brighter than any feature ever recorded on the planet […]

Hot 'Super-Earths' Provide Clues to Water in Exoplanet Atmospheres

Some of the most interesting exoplanets discovered so far are the “super-Earths,” rocky worlds which are significantly larger and more massive than Earth but still smaller than the […]

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), […]

The search for exoplanets is about to enter an exciting new phase, as the Transiting Exoplanet Survey Satellite (TESS) mission has now been cleared for development by NASA. TESS will greatly expand the number of stars being observed for evidence of exoplanets […]

'Planet Hunters' Citizen Scientists Discover Distant Exoplanet With Time-Keeping Issues

After analyzing many millions of light curves that were obtained by NASA’s Kepler space telescope, a team of volunteers from the ‘Planet Hunters’ citizen science project, have discovered a distant exoplanet,named PH3c, which exhibits a highly irregular orbital period around its host star.

Punctuality is considered one of the basic cultural […]

New Uranus-Like 'Ice Giant' Exoplanet Discovered

Many different kinds of exoplanets have been found by astronomers, from giant “hot Jupiters” and “super Earths” to smaller rocky worlds like Earth or Mars. Now, another type has been discovered, an “ice giant” similar to Uranus or Neptune in our […]

Astronomers Create Most Detailed Weather Map Yet of an Exoplanet

Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data […]

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 […]

Bizarre Universe: Massive Black Hole In Tiny Galaxy and Exoplanet That Makes Its Star Act Older Than It Is

The universe is a wild and weird place, and two recent findings from orbiting space telescopes illustrate just how bewildering it can be: a monster-sized black hole in one of the tiniest galaxies known and a huge exoplanet that is […]

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 […]
