For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). Today, […]

GJ 1132b: Nearest Earth-Sized Exoplanet Discovered So Far May Be a 'Venus Twin'

Astronomers have discovered another Earth-sized exoplanet that is the closest one to our own Solar System found so far, but it might not be a nice […]

NASA Space Telescope Sees Possible X-Ray 'Screams' From Zombie Stars

The Kepler space telescope has been nothing short of incredible, revolutionizing our understanding of exoplanets and showing just how common and diverse they really are (as the saying goes, truth is stranger than fiction). Recently, however, additional mechanical problems […]

Kepler Space Telescope Discovers Best Candidates for Habitable Worlds Outside Our Solar System

This diagram shows the worlds discovered orbiting the star Kepler-62 compared with the terrestrial planets in our own solar system. Two worlds have been discovered in this and the Kepler-69 system which exist in the so-called habitable zone. Image Credit: NASA/Ames/JPL-Caltech

The Kepler Space Telescope has discovered two planetary systems that have worlds either […]
