Scientists identify new shark species in the Atlantic Ocean

Image
Sixgill sharks are among the oldest creatures on Earth, with ancestors dating back to over 250 million years, well before dinosaurs.   Scientists at the Florida Institute of Technology have identified and confirmed the existence of a new shark species residing in the Atlantic Ocean. For confirmation, scientists used genetic testing and named the species “Atlantic sixgill shark.” The shark is different than its counterparts in the Indian and Pacific Oceans and measures up to 6 feet in length. “We showed that the sixgills in the Atlantic are actually very different from the ones in the Indian and Pacific Oceans on a molecular level, to the point where it is obvious that they’re a different species even though they look very similar to the naked eye,” said Toby Daly - Engel, Assistant Professor and shark biologist at the Florida Institute of Technology. Atlantic sixgill sharks are far smaller than their Indo-Pacific relatives, which can grow to 15 feet o...

Space Astronomers Spy Swarms of The Massive Black Hole At the Centre of Milky Way

Image
For the first time astronomers have glimpsed a long-predicted population of black holes lurking at the heart of the Milky Way. Scientists already knew our galaxy’s core holds a supermassive black hole weighing millions of times more than our sun, and that this great beast is enveloped by a diverse entourage of lesser companions. Trapped in its gravitational clutches, run-of-the-mill stars whip around this gargantuan black hole like fireflies in a hurricane. So, too, do astrophysical exotica such as neutron stars and white dwarfs—the remnants left by normal stars when they die. Presumably black holes should be there as well, either born on the galactic center’s doorstep from the deaths of massive stars or arriving via migration from farther out. Such black holes should each weigh 10 to 20 times more than our sun. That bulk would make them behave a bit like heavy pebbles outpacing fine silt to the watery bottom of a well, jostling through the lighter surrounding stars to reach stab...

SpaceX's biggest rival has a 'genius' plan to cut its rocket launch costs more than 70%

SpaceX turned heads around the world on February 6 with the first-ever launch of Falcon Heavy. The 230-foot-tall rocket's three boosters helped push Elon Musk's Tesla Roadster into space, peeled off after running low on fuel, and then careened toward Earth. Two of the 16-story boosters rocketed to a safe landing (the third fell into the ocean), and the flight was hailed as a huge success. It proved SpaceX could lift twice as much payload to space for about 25% of the cost of its closest competitor while recycling rocket parts worth tens of millions of dollars. That primary rival is United Launch Alliance, a company that aerospace industry titans Boeing and Lockheed Martin formed in 2005. ULA's largest rocket, the Delta IV Heavy, costs $350 million per launch, according to company CEO Tory Bruno. Delta IV Heavy is far more expensive t...
