Astronomers have identified a distant galaxy whose stars and gas behave as if embedded in a cloud of negative mass, forcing cosmologists to rethink gravity, dark matter, and the fate...
Astronomers have captured the first-ever spatially resolved images of a superluminous supernova bent by gravity from distant galaxies, offering a magnified glimpse into a cosmic explosion from 10 billion years...
Astronomers have discovered one of the largest rotating structures ever seen in the universe: a razor-thin, galaxy-spanning filament that spins like a slow cosmic turbine, challenging long‑held assumptions about how...
A distant, impossibly bright stellar death called SN 2025wny has just become one of cosmology’s sharpest tools, bending space-time itself into a natural telescope that may help resolve the universe’s...
A new X-ray census reveals that most small galaxies are missing the supermassive black holes we thought were universal — forcing a rewrite of how cosmic structures grow, trade, and...
