Largest Known Star Self Destructs
2013-10-16 12:49:05

Lee Rannals for redOrbit.com - Your Universe Online A group of international scientists have been observing as the largest known star in the Universe tears itself apart. Astronomers from the UK, Chile, Germany and the US have watched as W26 in the Westerlund 1 star cluster shed its outer layers and flings a huge cloud of glowing hydrogen gas out to return enriched material back to the interstellar medium. The latest observation, reported in the journal Monthly Notices of the Royal...

ESA XMM-Newton Telescope Captures Space Bubble
2012-10-29 13:26:16

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency (ESA) has released an image of the cauldron bubble as seen by its XMM-Newton space telescope. The cauldron bubble lies 5,000 light-years away from Earth, and is a bubble bursting with the fiery stellar wind of a star. Sitting in the constellation of Canis Major, the bubble spans nearly 60 light-years across and was blown by the stellar wind of the Wolf Rayet star HD 50896. This pink star is near...

A team of European researchers have pinpointed a magnetar--an unusual type of neutron star that possesses an immensely powerful magnetic field--that was formed by a star that had at least 40 times more mass than our solar system's sun.The discovery, they say, could force scientists to rethink current theories of star evolution, and specifically, the amount of mass needed to form a black hole.According to the scientific website PhysOrg.com, "This proves for the first time that magnetars can...

Astronomers using data from several X-ray satellites have caught a magnetar "“ the remnant of a massive star with an incredibly strong magnetic field "“ in a sort of giant cosmic blench. When it comes to eerie astrophysical effects, the neutron stars commonly known as magnetars are hard to beat. The massive remnants of exploded stars, magnetars are the size of mountains but weigh as much as the sun, and have magnetic fields hundreds of trillions of times more powerful than the...

ESO's Telescopes Uncover Super Star Cluster in the Milky Way ESO -- Super star clusters are groups of hundreds of thousands of very young stars packed into an unbelievably small volume. They represent the most extreme environments in which stars and planets can form. Until now, super star clusters were only known to exist very far away, mostly in pairs or groups of interacting galaxies. Now, however, a team of European astronomers [1] have used ESO's telescopes to uncover such a monster...
