NASA Kepler mission discovers 715 new planets

NASA's Kepler mission has made an exciting discovery and subsequent announcement: the discovery of 715 new planets orbiting 305 stars. Says the space agency, about 95-percent of the newly discovered planets are smaller than Neptune, making them more or less around the size of Earth, and makes for a "significant increase" in known small planets.

Exoplanets can be weighed using starlight, reveal scientists

Exoplanets can be weighed using starlight, reveal scientists

Two MIT planetary scientists, Julien de Wit and Sara Seager, have published research showing how it is possible to determine the weight of an exoplanet using the surrounding starlight. Not only does this represent a way to determine the weight of something that is seemingly impossible to gauge, it will also facilitate the hunt for planets that are most like our own, possibly expediting the discovery of a planet like Earth.

Kepler Space Telescope data suggests up to 40 billion Goldilocks planets

Kepler Space Telescope data suggests up to 40 billion Goldilocks planets

A new analysis of Kepler Space Telescope data by Berkeley astronomers suggests that as many as 40 billion planets with climates similar to Earth's may be calculated to exist in the Milky Way galaxy. Of those, 11 billion orbit stars similar to our sun. The rest of the hypothetical planets orbit red dwarf stars, which are the same size as our sun but cooler. New news nicely complements the more in-depth recent mineral analysis of the single planet Kepler Planet 78b.

Nearest Earth-like planet only 13 light-years away

Nearest Earth-like planet only 13 light-years away

Finding planets that are similar to Earth is a task that scientists and researchers have been working on for a while now, but it seems like they're making great strides in their findings. Astronomers have reported that the nearest Earth-like planet is possibly just 13 light-years away (77 trillion miles).

Rogue planet without sun spotted 100 light-years away

Rogue planet without sun spotted 100 light-years away

It wasn't too long ago when astronomers thought that solar systems outside our own would be more or less similar to ours -- there would be a central sun, with various planets of both rocky and gassy varieties. However, that's definitely not the case all the time. Today, astronomers have discovered a rogue planet that's uncommon from other planets like it.

Hubble Space Telescope spots fifth moon orbiting Pluto

Hubble Space Telescope spots fifth moon orbiting Pluto

Pluto may no longer be able to roll with the big boys, but that isn't stopping NASA scientists from continuing to take an interest in it. As it turns out, the Hubble Space Telescope has discovered a fifth moon orbiting the solar system's second-most-massive dwarf planet. P5, as it's being called, is an irregularly shaped moon that's 6 to 15 miles across and whips around Pluto in a 56,000-mile-diameter circular orbit.
