Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.
Earth’s new address: ‘Solar System, Milky Way, Laniakea’
New Species of Dinosaur Weighed as Much as a Dozen Elephants: A new species of dinosaur found in Argentina was a 65-ton behemoth the length of a high-school basketball court, making it one of the largest animals to ever walk the Earth, researchers said Thursday.

NASA: Astronomers from the University of Maryland, College Park (UMCP) and NASA’s Goddard Space Flight Center have uncovered rhythmic pulsations from a rare breed of black hole in archival data from NASA’s Rossi X-ray Timing Explorer (RXTE) satellite. The signals provide compelling evidence that the object, known as M82 X-1, is one of only a few midsize black holes known.
Dying stars form modest black holes measuring up to around 25 times the mass of our sun. At the opposite extreme, most large galaxies contain a supermassive black hole with a mass tens of thousands of times greater. Just as drivers traveling a highway packed with compact cars and monster trucks might start looking for sedans, astronomers are searching for a middle range of the black hole population and wondering why they see so few.’
