There's a baby star 'sneezing' in the constellation Taurus — and it could solve a longstanding cosmic mysteryIn a rare observation, scientists found a baby star "sneezing" gas, dust and magnetic energy out of its disk. This behavior could help solve a longstanding mystery about how stars form without tearing themselves apart.

Largest 3D map of our universe could 'turn cosmology upside down'Scientists using the Dark Energy Spectroscopic Instrument have unveiled the largest 3D map of the universe ever. The results suggest that dark energy, the mysterious force pulling the universe apart, may be weakening, challenging prevailing theories of cosmology.

James Webb telescope detects oldest 'dead' galaxy in the known universe — and its death could challenge cosmologyAstronomers using the James Webb Space Telescope have detected the oldest "dead" galaxy ever observed, at just 700 million years after the Big Bang. The stalled-out relic defies explanation by our current knowledge of the early cosmos.
