Q. The Bullseye Galaxy (LEDA 1313424) was recently discovered by using which telescope?
Answer: Hubble Space Telescope
Notes: The Bullseye Galaxy, officially named LEDA 1313424, was recently discovered by an international research team using the Hubble Space Telescope and the W. M. Keck Observatory. This galaxy has a unique ringed structure formed around 50 million years ago due to a head-on collision with a blue dwarf galaxy. The collision created rippling waves of gas, which triggered star formation in circular rings. The Hubble Space Telescope observed eight rings, while the W. M. Keck Observatory in Hawaii confirmed a ninth ring. The galaxy spans 250,000 light-years in diameter, nearly five times larger than the Milky Way. Despite being 130,000 light-years apart, a thin gas trail still links the Bullseye Galaxy to the dwarf galaxy. Scientists believe it may evolve into a Giant Low Surface Brightness Galaxy, which could offer insights into dark matter.
