是这个黑洞的消息么

WASHINGTON -- Astronomers using NASA's Chandra X-ray Observatory have found evidence of the youngest black hole known to exist in our cosmic neighborhood. The 30-year-old black hole provides a unique opportunity to watch this type of object develop from infancy.

The black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others.

The 30-year-old object is a remnant of SN 1979C, a supernova in the galaxy M100 approximately 50 million light years from Earth. Data from Chandra, NASA's Swift satellite, the European Space Agency's XMM-Newton and the German ROSAT observatory revealed a bright source of X-rays that has remained steady during observation from 1995 to 2007. This suggests the object is a black hole being fed either by material falling into it from the supernova or a binary companion.

"If our interpretation is correct, this is the nearest example where the birth of a black hole has been observed," said Daniel Patnaude of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. who led the study.

The scientists think SN 1979C, first discovered by an amateur astronomer in 1979, formed when a star about 20 times more massive than the sun collapsed. Many new black holes in the distant universe previously have been detected in the form of gamma-ray bursts (GRBs).

However, SN 1979C is different because it is much closer and belongs to a class of supernovas unlikely to be associated with a GRB. Theory predicts most black holes in the universe should form when the core of a star collapses and a GRB is not produced.

"This may be the first time the common way of making a black hole has been observed," said co-author Abraham Loeb, also of the Harvard-Smithsonian Center for Astrophysics. "However, it is very difficult to detect this type of black hole birth because decades of X-ray observations are needed to make the case."

The idea of a black hole with an observed age of only about 30 years is consistent with recent theoretical work. In 2005, a theory was presented that the bright optical light of this supernova was powered by a jet from a black hole that was unable to penetrate the hydrogen envelope of the star to form a GRB. The results seen in the observations of SN 1979C fit this theory very well.

Although the evidence points to a newly formed black hole in SN 1979C, another intriguing possibility is that a young, rapidly spinning neutron star with a powerful wind of high energy particles could be responsible for the X-ray emission. This would make the object in SN 1979C the youngest and brightest example of such a "pulsar wind nebula" and the youngest known neutron star. The Crab pulsar, the best-known example of a bright pulsar wind nebula, is about 950 years old.

"It's very rewarding to see how the commitment of some of the most advanced telescopes in space, like Chandra, can help complete the story," said Jon Morse, head of the Astrophysics Division at NASA's Science Mission Directorate.

The results will appear in the New Astronomy journal in a paper by Patnaude, Loeb, and Christine Jones of the Harvard-Smithsonian Center for Astrophysics. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for the agency's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra's science and flight operations from Cambridge.

一定要将标题党的事业做强做大

作者: 轩辕十四 时间: 2010-11-16 08:28:54

好吧，我承认看完那个消息震精了……

作者: 轩辕十四 时间: 2010-11-16 08:38:33

@luzhengyu(卢正雨) 半夜不睡觉，激动万分的盯着NASA的视频直播，希望看到类似外星舰队之类的“惊天大秘密”，结果到最后只是宣布发现了一个5000万光年外的年轻黑洞。。。唉。。。（“奔三了，现实一点吧，哪有什么野人？”---《一只狗的大学时光》）

到底是什么消息呢?

作者: Hibino 时间: 2010-11-16 10:56:21

三十岁的黑洞啊。。。。。黑洞啊。。。。。。。。

作者: Go2Piha 时间: 2010-11-16 12:06:20

我靠，这个黑洞比我还年轻啊！

作者: Go2Piha 时间: 2010-11-16 12:07:51

500万光年远的黑洞，嗯，，，看来我老掉前这个黑洞是吸不到地球的，很奇怪何以判断只有30岁大呢？难道黑洞旁边有天朝的身份证、户口本？

作者: 哪有这么多好事? 时间: 2010-11-16 12:10:18

米国和棒子要联手统治宇宙了

作者: joy___123 时间: 2010-11-16 12:17:13

标题党无敌了~~~~

要是真有啥外星舰队估计我们也不会比总统们晚多少知道~~~

作者: Ardell假睫毛 时间: 2010-11-16 12:37:05

我不太明白的是，5000万光年，就是5000万年前这个黑洞是30岁？

作者: tobefine 时间: 2010-11-16 12:51:20

全世界关注这件事情的人们这次说了一句中国话...

貌似这是第一次人们亲身见证到一个黑洞的诞生的过程~

“科学家们相信，这个30岁的黑洞是SN1979C残余部份，SN1979C是银河系M100的一颗超新星，是在一颗比太阳大20倍的星体爆炸时形成，距离地球大约5千万光年，1979年由一名天文爱好者发现。"

我还是比较喜欢美女的那个黑洞

不管有多深我都不怕，勇往直前。眼睛一闭义无反顾地往里面跳。

光年是距离单位不是时间单位，谢谢，我记得初中地理就讲过吧。。。。。。

不客气。

作者: Ardell假睫毛 时间: 2010-11-16 17:35:58

你没明白？我们现在观察到的是这个黑洞31岁的形态。。。

5000万光年之类没有关系。。。

嗯，谢谢，这样的解释比较清楚。
