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.

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.

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.

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

Jupiter's largest moons don't go completely dark when the giant planet blocks their sunlight. The discovery could reveal more about Jupiter's upper atmosphere, which may keep the moons lit when they are not directly illuminated by the sun.

A mysteriously bright anomaly winked in and out of existence on the seas of Saturn's largest moon, Titan — potentially the first time waves, bubbles or some other unknown features have been seen there, scientists say.
