Wind Nebula Discovered Around Rare Ultra-Magnetic Neutron Star, A First

For the first time ever, astronomers have discovered a vast cloud of high-energy particles called a wind nebula around a rare ultra-magnetic neutron star. A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova, which are the strongest magnets in the universe. After reviewing the discovery of a newly found nebula which surrounds a magnetar known as Swift J1834.9-0846, a team researcher George Younes, a postdoctoral researcher at George Washington University in Washington found an unusual lopsided glow about 15 light-years across centered on the magnetar.  ...

More Research Needed Into Gravitational Wave Astronomy

For the second time in history, astrophysicists have just announced that they have directly detected gravitational waves caused by the collision of two black holes. An Australian team has been analyzing data collected by the two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors in the US that picked up the first historic gravitational wave signal for months ago, and were actually able to watch two black holes orbiting each other 27 times in their last second before colliding. Team member Susan Scott, an astrophysicist from the Australian National University in Canberra said, “This has cemented the age of gravitational wave astronomy. This shows data is...

Second Gravitational Wave Detected

A new discovery was announced at an astronomical meeting in San Diego revealing that a second pair of black holes that devoured each other 1.4 billion years ago have been detected. The same group of astronomers that produced the first audio of the gravitational-wave chirps, they gathered that in the new merger, the black holes were roughly 14 and 8 times as massive as the sun, circled and combined into a single spinning black hole 21 times as massive as the sun. The collision spilled an amount of energy equivalent to the entire mass of the sun into space-time. Albert...
