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.  ...

Do You Ever Get The Feeling You Are Being Followed?

An unbelievable new discovery shows that Earth has a small “quasi-satellite” asteroid that keeps a constant orbit around our Sun, just as we do and may continue to do so for as long. Asteroid 2016 HO3 was first spotted by the Pan-STARRS 1 asteroid survey telescope in Hawaii, operated by the University of Hawaii’s Institute for Astronomy and funded by NASA’s Planetary Defense Coordination Office. Paul Chodas, manager of NASA’s Center for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory in Pasadena, California said “Since 2016 HO3 loops around our planet, but never ventures very far away as we both go around the...
