NASA’s Kepler Mission may have found our cousin with the confirmation of the first Earth-size planet in the “habitable zone” around a sun-like star.
Astronomers at the Lick Observatory atop Mount Hamilton have discovered three planets described as “supersized Earths” orbiting a star 54 light years away.
A strange celestial phenomenon is lighting up the western horizon after sunset during the next couple of weeks.
A graduate student at the University of California, Berkeley has discovered a relatively nearby solar system with three planets that are slightly larger than the size of Earth, and one of the planets has temperatures moderate enough to possibly support life.
NASA scientists have identified a whopping 1,000 planets outside the solar system using data from the Kepler telescope, which has recorded thousands more potential planets in our galaxy.
