First ever black hole image released 科学家公布首张黑洞照片

5cc7a14aa3104842e4ab5f2c.jpeg

天文学家们拍到了史上首张黑洞照片。照片中的黑洞位于遥远的星系中,直径达  400 亿公里。它被科学家们称为 “一个怪物”。

文字稿

A black hole is an object that has such a large gravitational pull, not even light can escape. It devours all that comes in its vicinity. The one photograph measures 25 billion miles across – that’s three million times the size of the Earth.

黑洞是一种引力极强的天体,连光都无法逃脱。它能吞噬一切邻近的物质。这张照片中的黑洞直径为 250 亿英里,是地球的 300 万倍。

The image shows an intensely white ring of fire. The lower half is considerably brighter, creating the impression of a smile amid the darkness of the cosmos. It's caused by superheated gas falling into the hole and is brighter than all the billions of other stars in the galaxy combined.

这张图像展现了一圈强烈的白色火环。光环的下半圈明显亮得多,宛如黑暗宇宙中的一抹微笑。这是由过热的气体落入黑洞而造成的,它比该星系内数十亿恒星加起来还要明亮。

The ring surrounds a dark circle, which is the black hole itself. The image matches what theoretical physicists and indeed Hollywood directors, imagine black holes to look like. But having their first real picture will enable researchers to learn more about the nature of space and time and ultimately our own existence.

光环围绕着一个暗圈,它是黑洞本体。这张图像与理论物理学家甚至一些好莱坞导演想象的样子相符。但有了第一张黑洞的真实照片,研究人员们可以进一步探究时空的本质,并最终了解我们自身的存在。
