Astronomers have discovered an exoplanet in the star Gliese 832's "habitable zone" — the just-right range of distances that could allow liquid water to exist on a world's surface. The planet, known as Gliese 832c, lies just 16 light-years from Earth.
25 June 2014, 01:01 PM ET
Scientists have just discovered a distant galaxy with a trio of supermassive black holes at its core. The new finding suggests tight-knit groups of these giant black holes are far more common than previously thought.

Earth's nearest star has bad weather too. The sun's bad weather, however, is more than just a little rain and lightning. Huge droplets of hot plasma about the size of Maine fall from the sun's outer atmosphere (the corona) down toward its surface.

The asteroid-mining firm Planetary Resources and citizen-science site Zooniverse have teamed up to launch Asteroid Zoo, which asks people around the world to scour image archives for undiscovered space rocks that zoom close to Earth.
24 June 2014, 04:59 PM ET
The electrically charged gas falls from the Sun's corona to the surface. The 'coronal rain' was captured by Swedish 1-m Solar Telescope (SST).
24 June 2014, 04:37 PM ET
NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton satellite spotted a spike of X-ray emission coming from more than 70 galaxy clusters. The X-rays could be generated by the decay of one type of dark-matter particle.
24 June 2014, 03:06 PM ET
The mysterious signal was detected by NASA's X-Ray Observatory and ESA's XMM-Newton in the Perseus galaxy cluster and 73 others. Scientists think that this may be the work of a hypothetical particle called a sterile neutrino.
24 June 2014, 02:36 PM ET
The Big Bear Solar Observatory has delivered high definition views of a sunspot. The data will be used to unravel mysteries presented by these dark and concentrated magnetic fields.
24 June 2014, 09:20 AM ET
Scientists have identified what is possibly the coldest known white dwarf. In fact, this dim stellar corpse is so cold that its carbon has crystallized, effectively forming a diamond the size of Earth, astronomers say.
24 June 2014, 07:30 AM ET
Curiosity wraps up its 687th day on Mars today (June 24), NASA officials said, meaning the 1-ton robot has completed one lap around the sun on the Red Planet.
23 June 2014, 06:05 PM ET
A new 3D map of the Milky Way puts the dust that permeates the galaxy on display in great detail. Astronomers mapped the dust between stars in the Milky Way to create the colorful photo that spans the part of the galaxy seen from Earth's Northern Hemisphe
