One of the Universe’s prettiest mysteries — Hoag’s Object, a ring galaxy around 600 million light-years away in the constellation Serpens. Image Credit: NASA/ESA, Processing: Benoit Blanco

• Galaxy Name: Hoag’s Object • Galaxy Type: Ring galaxy • Constellation: Serpens • Distance: ~600 million light-years • Age: ~13 billion years • Stars: Estimated billions • Apparent Magnitude: 16.0 • Radius: ~120,000 light-years • Discovery: 1950 by Arthur Hoag #DidYouKnow: Ring galaxies are relatively rare, constituting about 1 in 10,000 of all observed galaxies. According to NASA, it’s possible that the blue ring of stars may be the shredded remains of a galaxy that passed nearby. Some astronomers estimate that the encounter occurred about 2 to 3 billion years ago. Image Description: A rare ring galaxy featuring a nearly perfect outer ring of young, bright blue stars surrounding a yellowish, densely packed core. The dark void between the core and the ring enhances its distinct appearance. The image captures the galaxy against a backdrop of faint stars and distant galaxies, highlighting its symmetry and uniqueness. Media Credit: NASA/ESA, Processing: Benoit Blanco.
