Phase II: Support two hosted-payload missions for validation. Benefits: Provide cost-effective solutions for payload validation, accelerate technology development, and strengthen collaborationRead More

Bullseye Galaxy

Current context: The Bullseye Galaxy was recently discovered by researchers using the Hubble Space Telescope. About Size: It is approximately 2.5 times larger than the Milky Way. Rarity: The galaxy features nine concentric rings, which is an extremely rare structure in the universe. Formation Theory: Scientists believe these rings formed when a blue dwarf galaxy passed through it nearly 50 million years ago, creating ripples in the gas that later developed into ring formations. Future Evolution: The Bullseye Galaxy is expected to gradually evolve into a Giant Low Surface Brightness (GLSB) galaxy over billions of years, as the rings dissipate.....Read More
