When a star is born, a chaotic light show ensues. NASA's long-lived Hubble Space Telescope captured vivid bright clumps moving through the cosmos at some 1,000 light years from Earth. The space agency called these objects clear 'smoking gun'

Landing on Mars is a challenge: The heavier the craft, the more difficult a safe landing becomes.Scientists propose using retropropulsion engines and angling the craft to create a pressure differential to land heavier crafts in the future. The post
Nearly a year in space put astronaut Scott Kelly's immune system on high alert and changed the activity of some of his genes compared with those of his Earth-bound identical twin, researchers said Friday. Scientists don't know if the changes were
Farewell, Opportunity: Rover dies, but its hugely successful Mars mission is helping us design the next one
NASA's Opportunity rover on Mars has been officially pronounced dead. Its amazingly successful mission lasted nearly 15 years, well beyond its initial three-month goal. Opportunity provided the first proof that water once existed on Mars and shaped
Astronomy & Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) orbiter has been collecting atmospheric readings but now is taking on a new job as a data relay satellite for the Mars 2020 mission that launches next year. The post NASA’s MAVEN orbiter has a
NASA tracks 500,000 chunks and bits of space junk as they hurtle around Earth. Some 20,000 of these objects are larger than a softball.To clean up the growing mess, scientists at the University of Surrey have previously tested a net to catch chunks
Why did the hominin cross the plain? We may never know. But anthropologists are pretty sure that a smattering of bare footprints preserved in volcanic ash in Laetoli, Tanzania bear witness to an evolutionary milestone. These small steps, taken
Anker’s Nebula Capsule mini projector gets all the hype, but if its standard definition resolution and 100 lumen brightness won’t cut it for your portable cinema needs, the newer Nebula Mars II is on sale for $390 today, the best price we’ve seen by
The Mars Opportunity Rover landed on the Red Planet's surface in 2004 for a 90-day mission of exploration. More than 14 years later, NASA has finally closed the book on this tiny rover that wandered across Mars sending back troves of information.
The International Space Station just received a fancy new gadget in the form of a Refabricator, a machine capable of 3D printing using recycled plastic materials.Here's how it works. The post NASA’s ‘Refabricator’ lets astronauts recycle 3D-printed
