Ever since scientists began to grasp the staggering scale of the universe, we’ve wondered if there was other intelligent life out there. It certainly seems like there’s space. No one has come calling from another planet, or even sent a signal we can detect, though. This prompted famed physicist Enrico …

Theories abound to address how our moon was formed. After we brought moon rocks back from the lunar excursions of the 60s, certain facts became clear, like the striking similarity between Earth’s chemical composition and that of the moon. Like the blind men with the elephant, we’re still at a …

NASA is preparing for a pair of new asteroid-exploration missions, which will launch in the early 2020s. These missions are part of the Discovery Program, which seeks to investigate remnants of the early solar system in a somewhat low-cost way. Past Discovery missions include Mars Pathfinder, Stardust, and Dawn. The …

Attempts to investigate the origin of giant wedge-shaped sedimentary structures on Saturn’s moon Titan using analogues in Death Valley, California has thrown up new questions about the surface processes and intense rainfall that might have formed them. A vast alluvial fan in the XinJiang province of China. The right side …

The universe is a big place, and we know from targeted observations that there are a lot of black holes out there. These collapsed husks of dead stars have such intense gravity that nothing escapes them, not even light. That makes it tricky to actually observe them, but NASA’s Chandra …
