Existence of 'Lost Continent' Under Indian Ocean Confirmed --"Remnant of the Primeval SuperContinent Gondwana"

 

Mauritius

 

Scientists have confirmed the existence of a "lost continent" under the Indian Ocean island of Mauritius (above) that was left-over by the break-up of the supercontinent, Gondwana, which started about 200 million years ago. The piece of crust, which was subsequently covered by young lava during volcanic eruptions on the island, seems to be a tiny piece of ancient continent, which broke off from the island of Madagascar, when Africa, India, Australia and Antarctica split up and formed the Indian Ocean.

A recent analysis of data for millions of stars from the Gaia space mission show that many stars in the halo that surrounds the Milky Way travel in groups..  Astronomers report their discovery today in the international journal Astronomy & Astrophysics.

NASA: Hidden Flares on Far Side of the Sun Blasting Gamma Rays to Earth Near Speed of Light

On three occasions, NASA's Fermi Gamma-ray Space Telescope has detected gamma rays from solar storms on the far side of the sun, emission the Earth-orbiting satellite shouldn't be able to detect. Particles accelerated by these eruptions somehow reach around to produce a gamma-ray glow on the side of the sun facing Earth.

Cloud of Cosmic Dust that Formed Earth --"Traced to Giant Stars"

Scientists have identified the origin of key stardust grains present in the dust cloud from which the planets in our Solar System formed, a study suggests. The researchers solved a long-standing puzzle concerning the source of the grains, which formed long before our Solar System and can be recovered from meteorites that fall to Earth. The discovery was made by an international team at an underground laboratory in Italy. The Laboratory for Underground Nuclear Astrophysics - or LUNA - is located more than one kilometer beneath the Earth's surface, hosted by the Italian Institute for Nuclear Physics Gran Sasso Laboratory.

"Oldest Known Human Ancestor" --Revealed by Discovery in Central China of Microscopic Sea Fossil

"To the naked eye, the fossils we studied look like tiny black grains, but under the microscope the level of detail was jaw-dropping, " Simon Conway Morris, from the University of Cambridge told BBC News. "We think that as an early deuterostome this may represent the primitive beginnings of a very diverse range of species, including ourselves. All deuterostomes had a common ancestor, and we think that is what we are looking at here."

"The Great Repeller"--Previously Unknown Region Void of Galaxies is Pushing the Milky Way at Hyperspeed (VIDEO)

Until now, scientists assumed that a dense region of the universe is pulling us toward it, in the same way that gravity made Newton's apple fall to earth. The initial "prime suspect" was called the Great Attractor, a region of a half dozen rich clusters of galaxies 150 million lightyears from the Milky Way. Soon after, attention was drawn to an area of more than two dozen rich clusters, called the Shapley Concentration (image above), which sits 600 million lightyears beyond the Great Attractor, which is not an object but a instead point in the center of the supercluster of galaxies in which our Milky Way exists.

"Universe Could Be a Hologram" --Rosetta Stone That Opens the Uncharted World of Quantum Gravity (VIDEO)

"The key to understanding quantum gravity is understanding field theory in one lower dimension," said Niayesh Afshordi, professor of physics and astronomy at the University of Waterloo. "Holography is like a Rosetta Stone, translating between known theories of quantum fields without gravity and the uncharted territory of quantum gravity itself."

ESA's "Moon Temple" -- Artist in Residence Designs Spiritual Center on Peaks of Eternal Light for Future Lunar Base (VIDEO)

The European Space Agency (ESA) has been very vocal about its intentions to create a 3D printed base on the moon, and the Shackleton Crater is one location that has been pinpointed as a promising one for a future settlement because of its depth and darkness, which create what’s known as a “cold trap” that may hold reserves of ice – meaning that it could serve as a source of water, oxygen and fuel. Meanwhile, its sunlit peaks provide an ideal location for living and working.

"The Biggest Mystery in Astrophysics Today" --Flashes from an Unknown Source Far Beyond the Milky Way (Today's "Galaxy" Stream)

Perhaps the source "is a dwarf galaxy that contains a supermassive black hole, or is the nucleus of a disrupted galaxy or even just an isolated black hole,” Heino Falcke, a radio astronomer and astroparticle physicist at Radboud University Nijmegen in the Netherlands told the LA Times about mystery milliseconds-long flashes detected by researchers at Cornell University and a global team. “Maybe the persistent source is something completely different – for example, an exploding star ‘disguised’ to look like a black hole. And are these bursts made by the black hole itself, or by something else in orbit around it? After all, supermassive black holes are typically surrounded by dense star clusters."
