ESO's Journey to the Most Remote Galaxy in the Observable Universe (WATCH Today's 'Galaxy' Stream)  

    An international team of astronomers using the European Southern Observatory (ESO) Very Large Telescope high in the mountains of Chile measured the distance to the most remote galaxy so far. This is the first time that astronomers have been able to confirm that they are observing a galaxy as it was in the era of reionization — when the first generation of brilliant stars was making the young Universe transparent and ending the cosmic Dark Ages. A team of astronomers used E...

Jupiter and Saturn's Rapid Early Growth Was the Source of Most of the Water on Earth  

  "First of all, it's important to leave aside the idea that Earth received all its water via the impacts of comets from very distant regions. These 'deliveries' also occurred, but their contributions came later and were far less significant in percentage terms," said Andre Izidoro, with the School of Engineering of Sao Paulo State University, Brazil. "Most of our water came to the region currently occupied by Earth's orbit before the planet was formed." Equipped with Newton's law of ...

NASA Scientists Debate Alien Planet 55 Cancri e --"Does It Have an Atmosphere Like Earth & Venus?"

"But the lava would be hidden from our view by the thick atmosphere. Understanding this planet will help us address larger questions about the evolution of rocky planets."

Dinosaur Extinction Triggered Switch of Mammals from Nocturnal to Daytime Activity  

    Mammals only started being active in the daytime after non-avian dinosaurs were wiped out about 66 million years ago (mya), finds a new study led by UCL and Tel Aviv University's Steinhardt Museum of Natural History. A long-standing theory holds that the common ancestor to all mammals was nocturnal, but the new discovery reveals when mammals started living in the daytime for the first time. It also provides insight into which species changed behavior first. The study, publ...

  Black holes are famous for being ravenous eaters, but they do not eat everything that falls toward them. A small portion of material gets shot back out in powerful jets of hot gas, called plasma, that can wreak havoc on their surroundings. Along the way, this plasma somehow gets energized enough to strongly radiate light, forming two bright columns along the black hole's axis of rotation. Scientists have long debated where and how this happens in the jet. Astronomers have new clues t
