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 […]

'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 […]

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 Discover First Ice Giant Exoplanet Candidate in Long-Period Orbit

This artist’s concept shows Kepler-421b, a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra.

Astronomers on Monday made a “big” announcement about exoplanets, and it is big—literally. Another new world has been discovered, which is quite routine now these days, but this one is different, and unexpected: a planet which is more than twice as large […]

Kepler Phase 2: Planet-Hunting Space Telescope's New Mission Proposal Approved

Today was another big day for those interested in space exploration and in the search for other Earth-like, alien worlds in particular: The first Earth-sized exoplanet orbiting another star in the habitable zone has been discovered, it was […]

Exoplanet Bonanza: Kepler Confirms More than 700 New Worlds

There was more exciting exoplanet news this week from the Kepler mission: the space telescope has confirmed 715 new exoplanets! This brings the current total number of such worlds to 1,766, of which 961 have been found by Kepler. There are […]

PLATO Exoplanet Mission Proposal Awaits Final Selection by ESA, Following Recent Positive Recommendation

The European Space Agency’s PLATO mission aims to discover and characterize hundreds of Earth-sized exoplanets inside the habitable zones of approximately 1 million stars. The mission is likely to be approved for implementation by ESA during an announcement due for next week. Image Credit: PLATO Definition Study Report/ESA

Of Exoplanets and Habitability: Exploring the Possibility of 'Superhabitable Worlds'

Artist’s impression of an exoplanet with a mass approximately 3.6 times that of Earth, discovered orbiting just inside of the habitable zone of the Sun-like star HD 85512. Are “Super-Earths” such as this the most promising candidates for harboring extraterrestrial life? Image Credit: ESO/M. Kornmesser

“For there is a single general space, a single […]
