Ancient fish fossils could reveal how jaws first evolvedPosted on October 22, 2016 by Joseph Scalise These Qilinyu fish-ancestors lived 423 million years ago, during the Silurian Period. Their fossils, unearthed in China’s Yunnan province, are described in the current issue of the journal Science.

Europe's ExoMars lander apparently crashed on the Red Planet, and an orbiting NASA spacecraft has spotted its grave, European Space Agency (ESA) officials said. The lander, named Schiaparelli, stopped communicating with mission control about 1 minute before its planned touchdown on Mars Wednesday morning (Oct. 19). Newly released photos of the landing site by NASA's Mars Reconnaissance Orbiter (MRO) seem to confirm what ExoMars team members had suspected — that Schiaparelli died a viole..>> view originalMore Snow Leopards Poached, Even as Bold Plan Fights Decline

The case for Planet Nine is growing. Two new findings presented at a planetary science meeting in Pasadena have uncovered hints for the existence of this distant, mysterious world in the motions of known solar system objects.The results could help astronomers home in on their otherworldly target, which — if it really is out there — could fundamentally alter our understanding of the solar system. The hunt for Planet Nine (also known as Planet X) began in earnest in 2014 after astronomers Scott ..>> view originalFossilized Jaw in Tanzania is the Oldest Evidence of a Right Handed Homo Habilis
Oct 22, 2016 11:31 AM EDT A group of researchers from the University of Kansas has found the oldest evidence of the right handed person, which is not from a Homo sapiens but a Homo habilis. The study, published in the Journal of Human Evolution, says that researchers have discovered a fossilized jaw, known as OH-65, from a Homo habilis in the Olduvai Gorge in Tanzania. Dating 1.8 million years ago, this is the oldest evidence on the evolution of right-handedness in human beings.

A group of citizen scientists and professional astronomers, including Carnegie's Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk—a primordial ring ...>> view originalLook Up! Orionid Meteor Shower Still Raining Bits of Halley's Comet
Astrophotographer Daniel McVey took this photo of an Orionid meteor in Summit County, Colo., on Oct. 21, 2012. The Orionids of 2016 peaked Oct. 20-21, but they may still appear bright in the sky in the days that follow. Credit: Daniel McVey The Orionid meteor shower may have peaked last night, but the fast, bright meteors will continue streaming across the sky in force for another night or two, according to a NASA expert. The meteors are remnants left in the wake of Halley's Comet, and ..>> view original
