NASA has released two horror movie-style posters for Halloween, celebrating two real exoplanets where the conditions would be frightful for any human. The agency has also made them downloadable so you ...

In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely hospitable to life. And as technology advances, astronomers only expect to ...

The exoplanet is believed to be one of the farthest known from Earth. This artist's map of the Milky Way shows the location of one of the farthest known exoplanets, lying 13,000 light-years away. Most ...

Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that ...

Astronomers have identified four exoplanets orbiting Barnard’s Star, a red dwarf star just 6 light-years away from Earth. No, really, this time it’s for real! We have to emphasize this because ...

An exoplanet is a planet from a different star system. Most known exoplanets orbit stars within the Milky Way, but with the help of powerful space telescopes, scientists have discovered exoplanets far ...

However, since the majority of exoplanets that have been found orbit very close to their parent star, that isn't necessarily a disadvantage. This technique does have other disadvantages, though, like ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...

In our solar system, Earth is one of but eight planets – nine if you really want to count Pluto – and the only one remotely hospitable to life. But look beyond our sun's gravitational pull into the ...
