常見例句雙語例句Previous estimates of M87's black hole mass registered at some 3 billionsuns, still 1,000 times the size of the Milky Way's welterweight black hole.原先估計M87星系的黑洞質(zhì)量為太陽的3億倍,仍然相當(dāng)于銀河系次中量級黑洞的1000倍。Most black hole mass seems to come from direct consumption (called accretion) of gas, indicating that a black hole needs a surrounding galaxy to grow.大多數(shù)黑洞聚集物看起來是直接從氣體(叫做沖擊層)的消耗中間來的,這表明一個黑洞的成長需要周圍有一個星系。Eventually, like a ripening fruit, the galactic mass gets bigger until its ratio to the black hole mass gets to what astronomers have observed in nearby galaxies.許多天文學(xué)家認(rèn)為,這個比率可以提供一個線索,透露出星系與黑洞形成的先后關(guān)系。huzhangao.blog.163.com權(quán)威例句"The fact that there's a very young cluster of stars indicates that the intermediate-mass black hole may have originated as the central black hole in a very low-mass dwarf galaxy, "Sean Farrell, of the Sydney Institute for Astronomy in Australia, said in a statement.MSN: Rare Black Hole Survives Galaxy's DestructionIn the galaxy NGC 1277, astronomers have discovered a black hole with the mass of 17 billion suns.FORBES: Astronomers Find One Of The Biggest Supermassive Black Holes YetWhen Farrell and his colleagues discovered HLX-1in 2009, it was the first intermediate-mass black hole known.MSN: Rare Black Hole Survives Galaxy's Destruction 返回 black hole mass
