Most astronomers are convinced of the existence of the so - called stellar black holes, which collapse out of single star and have masses up to 10 times that of the sun. a famous example of this kind of black holes is cygnus x - 1. likewise, supermassive black holes, which can have the mass of billions of stars and sit in the centre of galaxies, are also believed to exist
一向以來，大部份天文學家都相信宇宙中存在著兩種黑洞，一種是由單顆恆星塌縮而成，質量比太陽大約十倍的恆星型黑洞，例如天鵝座- 1另一種是超重黑洞，這種黑洞位於星系核心，質量可達太陽數十億倍，例如我們的銀河系中心，就有一個名為人馬座a ，質量比太陽大300萬倍的黑洞。 -
Two space observatories have provided the first strong evidence of a supermassive black hole stretching, tearing apart and partially gobbling up a star flung into reach of its enormous gravity, astronomers said
天文學家說兩個太空瞭望臺首次提供有力的證據，證明了超級巨大黑洞的存在，恆星闖入黑洞強大的引力場里就被它拉伸、撕裂甚至部分吞噬。 -
Their detailed origin remains unknown. that doesn t stop the astronomers from guessing though ! amongst the candidates are the collapse of supermassive stars over 60 times the mass of the sun, mergers of two neutron stars, or conversion of a neutron star to a strange star
另一方面，伽瑪射線爆發是發生在宇宙深處一種最強烈的爆炸，雖然至今而人們還未弄清它們的來源，但是這並沒有令天文學家放棄推測，其中的一些猜想，包括比太陽質量大60倍的巨型恆星正在塌縮兩顆中子星合併，或是中子星變為奇異星。
