Facts about Black Eye Galaxy
- 08
Observations at infrared wavelengths reveal that M64 harbors a hidden active galactic nucleus obscured by its dark dust lanes, classifying it as a type 2 Seyfert galaxy with significant hidden energy output.
- 07
Spectroscopic studies reveal that M64 experiences ongoing star formation within its dust lanes at a rate of approximately 0.3 solar masses per year, significantly higher than typical spiral galaxies.
- 06
M64 contains roughly 100 billion stars across its disk, with stellar populations in its dust-laden regions showing evidence of active star formation triggered by the galactic collision.
- 05
M64's spiral arms rotate at different angular velocities, with the inner disk completing one rotation every 140 million years while the outer disk takes approximately 260 million years.
- 04
Hubble Space Telescope observations in 2001 revealed that the Black Eye Galaxy's collision with a smaller companion galaxy roughly one billion years ago triggered the formation of its spectacular dark dust lane.
- 03
In 1992, astronomers discovered that the Black Eye Galaxy's dark dust lane spans approximately 22,000 light-years across its face, making it one of the most visually striking dust features observed in any spiral galaxy.
- 02
The Black Eye Galaxy's central supermassive black hole has a mass of approximately 56 million solar masses, making it significantly more massive than the Milky Way's Sagittarius A*.
- 01
Approximately 47 million light-years away, the Black Eye Galaxy rotates with a counterclockwise outer disk moving opposite to its clockwise inner disk, creating its distinctive dark dust lane appearance.
