"Unlike Anything We've Seen Before" --Neutron-Star Merger Afterglow Continues to Brighten  

    The afterglow from the distant neutron-star merger detected last August has continued to brighten - much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational waves rippling through the universe. New observations from NASA's orbiting Chandra X-ray Observatory, reported in Astrophysical Journal Letters, indicate that the gamma ray burst unleashed by the collision is more...

Microbial Life in the Solar System Can Now Be Directly Detected --"First Since the Mars Viking Missions in the 70's"  

    "The search for life is a major focus of planetary exploration, but there hasn't been direct life detection instrumentation on a mission since the 70s, during the Viking missions to Mars," explains Dr Jacqueline Goordial. "We wanted to show a proof-of-concept that microbial life can be directly detected and identified using very portable, low-weight, and low-energy tools." At present, most instruments on astrobiology missions look for habitable conditions, small organic mole

"The Antarctic is very important in locking away carbon in deep-sea sediments. There is also a very rapid rate of sinking there - it has some of the coldest waters i...

Today's Top Space Headline: "Here Come the Star-Trek Voyages" --NASA Will Navigate Deep Space Using Pulsars  

    Half a century ago, astronomers observed their first pulsar: a dead, distant, ludicrously dense star that emitted pulses of radiation with remarkable regularity. So consistent was the object's signal that astronomers jokingly nicknamed it LGM-1, short for "little green men."   It wasn't long before scientists detected more signals like LGM-1, reports today's Wired. That decreased the odds that these pulses of radiation were the work of intelligent extraterrestrials. B

"Eerily Similar" --Sea Level on Saturn's Titan, a Billion Miles from Earth  

Saturn's moon Titan may be nearly a billion miles away from Earth, but a recently published paper based on data from NASA's Cassini spacecraft reveals a new way this distant world and our own are eerily similar. Just as the surface of oceans on Earth lies at an average elevation that we call "sea level," Titan's seas also lie at an average elevation. This is the latest finding that shows remarkable similarities between Earth and Titan, the only other world we know of in our solar system t

Odd Star Observed Orbiting a Rogue Black Hole in an Ancient Globular Cluster

At first we thought it was a comet, then an asteroid, and now the International Astronomical Union has reclassified it as something new entirely, an interstellar object. The Hawaiian astronomers who discovered it aptly named it 'Oumuamua', which means "a messenger from afar arriving first", reflecting that this object is like a scout sent from the ...
