the Sun. Researchers named the monster black hole LB-1. (Xinhua) The Milky Way galaxy is estimated to contain 100 million stellar black holes -- cosmic bodies formed by the collapse of massive stars and so dense even light can't escape. Until now, scientists had estimated the mass of an individual stellar black hole in our galaxy at no more than 20 times that of the Sun. But the new discovery has toppled that assumption. The team, headed by Liu Jifeng, of the National Astronomical Observatory of the Chinese Academy of Sciences (NAOC), spotted the black hole, which has a mass 70 times greater than the Sun. Researchers named the monster black hole LB-1. The discovery was a big surprise. "Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu. "We thought that very massive stars with the chemical composition typical of our galaxy must shed most of their gas in powerful stellar winds, as they approach the end of their life. Therefore, they should not leave behind such a massive remnant. LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation." Until a few years ago, stellar black holes could only be discovered when they gobbled up gas from a companion star. This process creates powerful X-ray emissions, detectable from Earth, which reveal the presence of the collapsed object. The vast majority of stellar black holes in our galaxy are not engaged in a cosmic banquet though, and thus don't emit revealing X-rays. As a result, only about 20 galactic stellar black holes have

been accurately identified and measured. To counter this limitation, Liu and his team surveyed the sky with China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), looking for stars that orbit an invisible object, pulled by its gravity. This observational

Working with these guys was absolutely amazing. I swear, they can read minds! One thing, tho... their cat is cute and everything, but they shouldn??t be talking about her so often, it??s kinda creepy. Anyway, it was pleasure to work with them!
I didn't really like working with this company/guy (I'm still not sure if it's one-man show or two-man theatre) at all. Their cat is fine, but seriously, just shut the fuck up about her, could you?
Working with these guys was the best thing I have ever done in my life. They have beautiful cat. This is stupid, why don't just use the lorem ipsum :/.
