Last week was a good one for exoplanet enthusiasts, with yet more news relating to how other worlds are now […]

Gemini Planet Imager Concludes Year-Long Commissioning Phase, Begins Regular Science Observations With Impressive First Results

The circumstellar disk around the young star HR 4796A, as imaged by the Gemini Planet Imager, which is mounted on the 8.2-m Gemini South telescope in Chile. These images reveal a complex pattern of variations in brightness and polarization around the HR 4796A disk. The western side (tilted closer to the Earth) appears brighter […]

Kepler Confirms Over 1,000 Exoplanets, Finds More Potentially Habitable Worlds

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 […]

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.
