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 [...]

Three new exoplanets discovered in star cluster

Three more exoplanets have just been found, adding to a long and rapidly growing list, but their location makes them a bit more unique - they orbit three different stars in a star cluster rather than other isolated stars [...]

Carbon Worlds May Be Waterless, Finds NASA Study

This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in carbon — and dry. Chances are low that life as we know it, which requires liquid [...]

Strange New Worlds: Exoplanets Abound in the Cosmos (Part 2)

Astronomers have been dazzled by the sheer number of planets there seem to be in the galaxy. According to a recent estimate, there’s on average at least one [...]

Some Exoplanets May be Even More Habitable Than Earth

In the search for life elsewhere, the Earth is typically used as a standard against which other planets, or moons, are compared. Since our planet is teeming with [...]

Planets Orbiting Dying Stars Are Probably Dead Too

If you are searching for other inhabited worlds, almost any kind of star may do according to current findings, except perhaps for white dwarfs. As it turns out, planets [...]

New Super Earth Found 22 Light Years Away Could Support Life

Using public data from the European Space Observatory and measurements from the Keck Observatory’s High Resolution Echelle Spectrograph and the new Carnegie Planet Finder Spectrograph at the Magellan II Telescope, an international team of researchers has discovered a new potentially habitable super Earth located in the ‘goldilocks zone’ relative to it’s star.
