“Whatever we find out, that is what nature chose,” Kyle Cranmer, a physics professor at New York University, told Brian Resnick at VOX. "It’s a good attitude to have when your field yields great disappointments."

DNA Hints at Earlier Human Migration Out of Africa --"Faded Signal Points to About 90,000 Years Ago"

 

Santrance

Hints of an early exodus of modern humans from Africa may have been detected in living humans. Present-day people outside Africa were thought to descend from a group that left their homeland 60,000 years ago, crossing through Egypt into the Arabian Peninsula. Now, analysis of nearly 500 human genomes appears to have turned up the faded signal of an earlier migration of Homo sapiens that has all but vanished. So the genetic evidence has shown that every non-African alive today could trace their origins to this fateful dispersal, still holds.

China's Space Officials Confirm: 'Heavenly Palace' Space Station is Hurtling Towards Earth -- "It's Out of Control"

 

China-tiangong-1-space-lab


Tiangong 1, China’s first space laboratory, will come to a fiery end. Most decommissioned satellites either burns up over aa ocean or is ejected to a far-off orbital graveyard, but the 8-ton Tiangong 1’s end is shaping up to be something very different. Chinese officials reported during a Sept. 14 news conference in Jiuquan that they had lost control of the station.

NASA Astronomers Observe a Supermassive Black Hole Destroying a Star

 

PIA20027-16

 

"The black hole has destroyed everything between itself and this dust shell," said Sjoert van Velzen, at Johns Hopkins University. "It's as though the black hole has cleaned its room by throwing flames." Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed -- or "spaghettified" -- as the black hole swallows it.

Dwarf Galaxies Orbiting the Milky Way --"The Enigma At the Heart of the Dark Matter Mystery"

Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

ESO's ALMA Observatory Uncovers Secrets of Giant Space Blob

An international team using the Atacama Large Millimeter/submillimeter Array (ALMA), along with the European Southern Observatory’s Very Large Telescope (VLT) and other telescopes, has discovered the true nature of a rare object in the distant Universe called a Lyman-alpha Blob (LAB). Up to now astronomers did not understand what made these huge clouds of gas shine so brightly, but ALMA has now seen two galaxies at the heart of one of these objects and they are undergoing a frenzy of star formation that is lighting up their surroundings. These large galaxies are in turn at the center of a swarm of smaller ones in what appears to be an early phase in the formation of a massive cluster of galaxies. The two ALMA sources are destined to evolve into a single giant elliptical galaxy.

"The appearance of this ice cloud goes against everything we know about the way clouds form on Titan," said Carrie Anderson, a CIRS co-investigator at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study.

NASA will announce new findings about Jupiter's ocean-harboring moon Europa during a news conference at 2 p.m. EDT (1800 GMT) on Monday (Sept. 26). "Astronomers will present results from a unique Europa observation campaign that may be related to the presence of a subsurface ocean on Europa," NASA officials wrote in a media advisory Tuesday (Sept. 20).
