About image M
106 (also known as NGC 4258) is a spiral galaxy visible in the constellation of
Canes Venatici and about 25 million light years away. M106 is an example of Seyfert's galaxy; the detection of unusual radio wave
and X-ray emissions indicates that probably part of the galaxy is falling into
a supermassive black hole located in its center. The shape of M106 resembles that of the Andromeda Galaxy (M31), but with a
different inclination, so that all the structures of dust clouds on the
galactic plane are thus visible.
