COMMENTS ON THE PHOTO:
In this photo is visible:
– M77 (top), which is a spiral galaxy located in the constellation of the Whale, 52 million light-years from the Milky Way.The heart of Messier 77 houses a supermassive black hole (15 million times the mass of our Sun) which, by accreting large amounts of hot gas, emits X-rays. As a result, M 77 belongs to the Seyfert type galaxies. Spiral galaxies with an extremely dense and hot nucleus.
-The galaxy NGC 1055 (below, left) is located barely 60 million years from Earth. Seen from the edge, it extends over some 100,000 light-years in diameter, just like our own Milky Way galaxy.
M77 and Ngc 1055 are 500000 AL apart.
-Ngc 1072 on the left side, which is a barred spiral at 537 million light-years from Earth.
