NASA selects Sierra Nevada for Space Station Cargo transport contract
Industry News NASA selects Sierra Nevada for Space Station Cargo transport contract These Commercial Resupply Services (CRS-2) contracts are designed to obtain cargo delivery services to the space station, disposal of unneeded cargo, and the return of research samples and other cargo from the station back t..>> view originalCould this be the second largest black hole in the Milky Way?
There seems to be a massive black hole lurking in the Milky Way. Using the Nobeyama 45-meter radio telescope, a team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, came to that conclusion after first spotting an enigmatic gas cloud called CO-0.40-0.22, located only 200 light-years away from the center of the Milky Way.

Can anything be done to save them?
Poisonous chemicals banned decades ago threaten to irreparably harm orca whale populations around areas of Europe, ecologists say.The study, release Thursday, took samples of 1,000 orca whales, dolphins, and porpoises found that they were being harmed by PCBs (polychlorinated biphenyl). The scientists and study urged stricter rules for disposal of materials containing the toxic chemicals.PCBs are persistent organic compounds that were once widely used in plastics and building materials. They hav..>> view originalSpacewalk aborted after water leaks into astronaut's helmet
CAPE CANAVERAL, Fla. — Two astronauts aborted their spacewalk Friday and hurried back into the International Space Station after water leaked into one of the men’s helmets in a scary repeat of a near-drowning 2½ years ago.The trouble cropped up after the astronauts — including Britain’s 1st spacewalker — successfully restored full power to the space station.NASA astronaut Timothy Kopra took everyone by surprise when he reported a small water bubble and then a film of water inside his helmet.

When early humans began trekking out of Africa, they spread across Eurasia on foot. As some made it down into then-peninsular Southeast Asia, they would have run into a watery boundary, called Wallace's Line, that scientists thought essentially uncrossable by animals until around 50,000 years ago, whenHomo sapiensarrived with boat technology.But somehow another human species had crossed into that island region, called Wallacea, long beforeH. sapienseven reached Southeast Asia. In 2004, archaeolo..>> view original122-Foot Titanosaur: Staggeringly Big Dino Barely Fits into Museum
An incredibly long-necked dinosaur, with leg bones the size of couches, is so massive that is has invaded not one, but two rooms at the American Museum of Natural History (AMNH) in New York City. The enormous titanosaur—an herbivorous beast that weighed 70 tons (64 metric tons) when alive some 100 million years ago—is the newest permanent exhibit to join the museum. It measures 122 feet (37 meters) long, almost the length of three school buses. The behemoth is so large it dwa..>> view originalChina aims for 2018 landing on far side of the moon

Mystery solved. Researchers finally concluded that Iceman Ötzi's maternal lineage is now extinct. The Ötzi iceman lived over 5,300 years ago in the Eastern Alps.(Photo : South Tyrol Museum of Archaeology/EURAC/M.Lafogler)The ice mummy Ötzi has provided much information about theHomo Sapiensway of life. Sadly, a new research from the European Academy of Bolzano/Bozen (EURAC) clarified that Ötzi's maternal genetic line is now extinct.

Most luminous galaxy is ripping itself apartIn this far-off galaxy, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy.“It is like a pot of boiling water being heated up by a nuclear reactor in the center,” said Tanio Diaz-Santos of the Universidad Diego Portales in Santiago, Chile. This galaxy, called W2246-0526, is the most luminous galaxy known, according to research published in 2015, based on data ..>> view originalScientists stunned by brightest-ever supernova
Scientists may have spotted the most powerful supernova ever seen, some 3.8 billion light years away in deep space. Named ASASSN-15lh, it looks like a huge ball of hot gas and is radiating the energy of hundreds of billions of Suns. Ten miles across at its center, this object is putting on quite a show, creating a cosmic explosion about 200 times more powerful than a typical supernova and more than twice as luminous as the previous record-holding supernova.
