Astronomers Discover Bullseye Galaxy with Nine Star Rings
Aspect | Details |
---|---|
Galaxy Name | Bullseye Galaxy (LEDA 1313424) |
Discovery | Discovered by an international team of researchers. |
Location | Located 567 million light-years away in the Pisces constellation. |
Type | Giant elliptical galaxy, 2.5 times larger than the Milky Way (diameter: 250,000 light-years). |
Unique Feature | Nine glowing star rings -- the most ever observed around a single galaxy. |
Formation Event | Formed after a violent galactic collision with a smaller blue dwarf galaxy nearly 50 million years ago. |
Telescopes Used | NASA's Hubble Space Telescope (detected eight rings) and W.M. Keck Observatory (confirmed ninth outer ring). |
Scientific Significance | Acts as a natural laboratory for studying galactic evolution and dark matter dynamics. |
Dark Matter Research | The rings function as tracers to map the distribution and behavior of dark matter. |
Ring Dynamics | Rings move inward or outward, indicating ongoing dynamic galactic processes. |
Speculation | Researchers speculate a tenth ring may have existed but faded or became too diffuse to observe. |
