Finding the black hole in the night sky
Einstein was right. Black holes do exist.
On April 10, the first image of a black hole changed astronomical history. It was found in the heart of a gigantic elliptical galaxy 55 million light years away known as Messier 87. Einstein first proposed the existence of these cosmic vacuum cleaners that suck up light and matter more than 100 years ago.
In 1774, French astronomer Charles Messier started publishing a list of celestial objects known as the Messier catalogue. M87 is one of those objects. If you have a telescope with some patients, you can see M87 for yourself in the evening sky in the Virgo constellation.
First locate the handle of the Big Dipper. Then draw an imaginary arc with your figure towards to the next brightest star. That’s Arcturus in the constellation, Bootes. From there, spike down with you figure towards the horizon to the next bright star called Spica in the constellation Virgo. Through a telescope, find the Virgo cluster of about 1,200 galaxies, which includes M87.
