Most astronomers believe that the large concentration of mass at the galaxy's center is a black hole whose gravity is causing the gas to whirl.

大多数天文学家认为，星系中心的大量物质是一个黑洞，它的引力导致气体旋转。

Astrophysicists have found that when a supermassive black hole quickly devours gas and dust, it can generate enough radiation to abort all the embryonic stars in the surrounding galaxy.

天体物理学家发现，当一个巨大的黑洞快速吞噬宇宙中的气体和尘埃时产生的辐射，足够摧毁周围星系中初期形成的星体。

As the black hole feeds, the gas and dust heat up and spray out X-rays, as illustrated by the white rays.

Importantly, this mud also acts as a kind of plug in the hole, preventing any oil and gas from blasting up out of the hole.

But those lower-energy X-rays can be further distorted by layers of gas between the black hole and the Earth, and previous spin observations have been contentious.

This allowed natural gas to migrate up the hole and explode at the surface.
