Black Eye Galaxy (M64) Type, Location, Discovery
The Black Eye Galaxy, known as M64, is a distinctive spiral galaxy located in the constellation Coma Berenices. M64 gained its nickname due to a prominent dark band of absorbing dust in front of its nucleus, creating the appearance of a black eye. The Black Eye Galaxy was discovered in the 18th century by astronomer Edward Pigott, with Johann Elert Bode finding it after. Learn about M64’s distance from Earth, size, structure, and rotation patterns. The Black Eye Galaxy fascinates astronomers with its appearance and intriguing characteristics.
M64 belongs to the category of spiral galaxies with a central bulge and disk. The galaxy measures 70,000 light-years in diameter and contains two main spiral arms. Scientists identify the Black Eye Galaxy as a Seyfert galaxy with low nuclear activity. Astrophysicists summarize it as an Sa-type unbarred spiral galaxy with Seyfert 2 characteristics.

These measurements provide a comprehensive view of the Black Eye Galaxy’s size, encompassing both its physical diameter and its apparent size in the night sky.
What is the age of the Black Eye Galaxy?
The Black Eye Galaxy is 13.7 billion years old, based on the age of its oldest stars. Components of the galaxy exhibit varying ages, reflecting its complex evolutionary history. The oldest stars in the galaxy’s halo and globular clusters formed around 13.7 billion years ago. The bulge of the galaxy contains stars with an average age of 2.5 billion years. Stars in the main spiral pattern have an average age of 5 billion years. The youngest star-forming regions in the spiral arms are 800 million years old.
A merger event occurred 18 million years ago, triggering star formation activity and influencing the galaxy’s morphology. The merger event led to the redistribution of stars and the formation of new stellar populations. Star formation continues in the galaxy’s spiral arms, where molecular clouds collapse to form stars.
How many stars are in the Black Eye Galaxy?
The Black Eye Galaxy contains 100 billion stars. Scientists and researchers estimate this number. 100 billion stars reside in the galaxy’s disk, which is 3 times the size of its central bulge.

How far is the Black Eye Galaxy from Earth?
The Black Eye Galaxy resides 17 million light-years from Earth in the Coma Berenices constellation. Messier 64 (M64) and NGC 4826 are alternative names for this spiral galaxy. Edward Pigott observed it in 1779. The galaxy’s distinctive dark dust band earned it the “Black Eye” and “Evil Eye” nicknames.
Can you see the Black Eye Galaxy through a telescope?
The Black Eye Galaxy (M64) is visible through sized telescopes with 4-6 inch apertures. Amateur astronomers observe its central core and partial spiral arms. Visibility depends on telescope quality and observing conditions. Light pollution affects viewing. The Hubble Space Telescope has been used to study the Black Eye Galaxy.
The Black Eye Galaxy appears as a patch in the sky. Observers see its “black eye” feature through telescopes. Astronomers recommend 8-inch or telescopes for better views of the galaxy’s structure and details. Medium to high magnification eyepieces (100-200x) show the galaxy’s features.
Locations with minimal light pollution provide optimal viewing conditions. Clear, moonless nights offer good opportunities for observing the Black Eye Galaxy. Star charts or planetarium software help locate the galaxy in the night sky. The Black Eye Galaxy has a magnitude of 8.5 and a surface brightness of 13.2 mag/arcsec^2. Telescopes detect the galaxy due to its magnitude, though it is faint compared to other celestial objects.
