A pulsar known as J0002 has been clocked traveling more than 1,100 kilometers (700 miles) per second away from the place it was created in a supernova explosion. Astronomers are calling this rapidly-spinning neutron star a cannonball pulsar, as it races away from the center of the nebula which resulted from the massive explosion which created the object. This pulsar, rotating 8.7 times a second, is located 6,500 light years from Earth.Read More Faster than a Speeding Pulsar
Astronomers found a young solar system, looking much like our own did, billions of years in the past. Located 470 light years from Earth, the star DM Tau is surrounded by a disk of dust and gas, which show two rings where planets are forming, located at roughly the same distances as the asteroid belt and Neptune in our own solar system. The star, believed to be between three and five million years old, is seen in the constellation of Taurus the Bull.Read More Solar System Much Like Ours Found Forming Around Alien Star
Astronomers at The University of Leeds have found a pair of massive binary stars orbiting closer to each other than any system ever seen before. The star PDS 27, once thought to be a single star, was found to be just one member of a binary pair. The two stars orbit each other at a distance roughly equal to that between the Sun and Neptune. Roughly one-third of all stars in our galaxy are in systems containing two or more stars.Read More Massive Binary Stars Found Cuddling Together in Stellar Nursery
Astronomers have long theorized that planetary systems can be affected by stars passing near solar systems. However, direct evidence of this has never been seen, until now.
Sitting 300 light years from Earth, the star HD 106906 is accompanied by a planet 11 times the size of Jupiter, orbiting the pair of binary stars 738 times further away than the distance between the Earth and the Sun. Computer simulations show that roughly 12 million years ago, another pair of stars passed the system, altering the orbit of this giant world, pulling it far from its stellar companions. Had the encounter not taken place, this world would have crashed into the stars around which it orbits.
A river of 4,000 stars has been detected just 330 light years from the Sun. This grouping is one billion years old, and has circled the outer edge of the Milky Way Galaxy four times since its formation. Astronomers found the formation using the Gaia space telescope, operated by the European Space Agency.Read More Billion-Year-Old River of Stars Seen Flowing Near the Sun
For the first time ever, a supernova is seen in the first moments it erupts. Amazingly, it was spotted by an amateur astronomer. This is his story.Read More Amateur Astronomer Victor Buso Spots Supernova in First Moments of Explosion
