Bedtime Astronomy

Scientists at Columbia University have detected a subtle temperature pattern in the cosmic microwave background that reveals how gas moves inside galaxy clusters.

By combining observations from 25 clusters, researchers uncovered new evidence linked to rotation and cosmic mergers, opening a promising way to investigate the dynamics of these enormous structures.

The Vera C. Rubin Observatory in Chile has already uncovered two previously unknown Milky Way companions using early test data: an extremely faint galaxy and a star cluster hidden by dust.

These discoveries offer an early glimpse of what the observatory’s ambitious decade-long sky survey could reveal about our galaxy’s history, its formation, and the mysteries of dark matter.

New experiments suggest that molten rock deep inside Earth can absorb and store large amounts of dissolved oxygen under extreme pressure.

As magma rises toward the surface, falling pressure may release this stored oxygen into the atmosphere. The discovery could offer a new explanation for ancient changes in Earth's oxygen levels and reshape our understanding of the planet's geological history.

Astronomers investigated GRB 260310A, a strange cosmic explosion that produced a surprisingly bright afterglow despite its weak initial gamma-ray burst.

Observations revealed that the explosion came from a massive star, but Earth viewed its powerful jet from an unusual side angle. A delayed X-ray brightening also exposed a complex structure, with an ultrafast central jet surrounded by a slower, wider outflow. The discovery could help explain how many powerful stellar explosions remain hidden from our view.

How do giant planets end up orbiting dangerously close to their stars? New simulations suggest that supersonic shock waves in their atmospheres can drain orbital energy, driving planets inward.

Depending on the intensity of these disruptions, a planet may settle into a tighter orbit or lose much of its atmosphere. This mechanism could help explain the mysterious distribution of hot Jupiters and other giant exoplanets.
