Black Eye Galaxy

==Overview==
Black Eye Galaxy (also known as M 64, NGC 4826, UGC 8062, and MCG 4-31-1) is a Sb-type spiral galaxy in the constellation of Coma Berenices. It is 23,933 miles from our Solar system. It contains fewer stars and is smaller than the Milky Way, our own galaxy. Yet the reason it is well recognized is because it has a distinct dark galactic dust band that does not fully block the light coming from its yellowish-bright nucleus. As a result, the odd galaxy has earned a nickname called the Black Eye Galaxy due to the dark dust particles that make up the dark thick ring and that obstruct the stars behind them from shining. 
== Discovery ==
It was first discovered by English astronomer Edward Pigott on March 23, 1779. It was discovered separately by German astronomer Johann Elert Bode one year later, and on March 1, 1780, French astronomer Charles Messier added it to his Catalogue des Nébuleuses et des Amas d'Étoiles (translated to Catalogue of Nebulae and Star Clusters).https://freestarcharts.com/messier-64 
== Galactic structure ==
The Black Eye Galaxy has an interstellar medium made up of two roughly equal-mass, counter-rotating disks. The galaxy's most noticeable dust lanes are found in the inner disk. There is no detectable counter-rotation among the galaxy's star population. Potential creation scenarios include the ongoing accretion of gas clouds from the intergalactic medium or a merger with a gas-abundant satellite galaxy in a retrograde orbit. The Black Eye Galaxy has an HII/LINER nucleus and is a type 2 Seyfert galaxy.https://doi.org/10.3847%2F1538-4357%2Faa8302 A faint radio emission source is located in the center.https://ui.adsabs.harvard.edu/abs/2009A&A...493..525I It has been discovered that a faint X-ray source near the nucleus is most likely emanating from the circumnuclear area rather than an active galactic nucleus.https://iopscience.iop.org/article/10.1088/0004-637X/731/1/60 A molecular-gas inner disk with a truncated radius of 2,300 ly exists (700 pc). Although the disk's non-rotational movements do not currently significantly feed the galaxy's core, they do stimulate star formation, which results in the galaxy's estimated 100 billion stars. There is also proof of a recent massive influx.https://ui.adsabs.harvard.edu/abs/2003A&A...407..485G
