Black hole in our galaxy – level 2
Scientists showed the first image of the black hole which is at the center of our galaxy.
The image doesn’t actually show the black hole. The black hole’s gravity is so strong that we can see only a bright ring around it. The ring is the material, gas, and dust which the black hole is swallowing.
The black hole is four million times the mass of our Sun. The ring around it is about 60 million kilometers, which is about the same as Mercury’s orbit around the Sun.
To take the image, scientists used eight different telescopes around the world. They believe the image will help them understand gravity and how materials behave in the black hole.
Difficult words: gravity (the strength which pulls objects together), mass (an amount of something), orbit (the path of an object around a planet or star).
