'Active SETI' sounds like science fiction, but some astronomers are discussing it seriously today. The idea is a controversial, hot-button issue, with some researchers wary of sending signals out to touch base with intelligent aliens.

A colossal but glancing smashup with a roughly Earth-size planet could have stripped away much of proto-Mercury's rocky mantle, explaining why the tiny, sun-scorched world has such a huge iron core today, researchers say.

The subsurface ocean inside Saturn’s largest moon, Titan, could be as salty as any body of water here on Earth, a new study reports. Data collected by NASA's Cassini mission suggests Titan's ocean is as salty as the Dead Sea.

The image, taken on Wednesday morning (July 2) by a crewmember of the orbiting lab's current Expedition 40, actually captures Arthur when it was still classified as a tropical storm. (Arthur strengthened to hurricane status early Thursday.)

What astronomers thought were a pair of potentially life-friendly alien worlds are illusions, apparitions conjured up by a star's intense magnetic activity, a new study suggests.
03 July 2014, 02:01 PM ET
Astronomers have for the first time detected a rocky alien world in an Earth-like orbit around just one star in a two-star system. The new find suggests that such worlds may be common, researchers say.

Turns out that two candidate planets thought to reside in the habitable zone of red dwarf star Gliese 581 are not planets at all. New research by astronomers at Penn State University finds that the signals were just magnetic activity from the star.
