Earth may have been ravaged by “invisible” explosions from space
Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike crater-forming impacts, these events unleash extreme heat and pressure without leaving obvious scars, making them harder to detect.

Gravitational waves may reveal hidden dark matter around black holes
Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded by future space observatories.

Astronomers just watched a black hole twist spacetime
Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made over 100 years ago and reveals new clues about how black holes spin and launch jets.

The western U.S. Tried to stop wildfires and it backfired
Much of the western U.S. is overdue for wildfire, with decades of suppression allowing fuel to build up across millions of hectares. Researchers estimate that 74% of the region is in a fire deficit, meaning far more land needs to burn to restore healthy forest conditions. Catching up would require an unprecedented amount of controlled and managed fire.

Your body feels cold in two different ways
Researchers have uncovered that the body uses different molecular systems to sense cold in the skin versus internal organs. This explains why surface chills feel very different from cold experienced deep inside the body.
