A new global study finds that human-caused climate change added over 30 extra days of extreme heat for nearly half the world’s population last year, raising urgent calls to cut fossil fuel emissions and improve heat safety.

New lab experiments and James Webb Telescope data show Europa’s icy surface constantly changing due to heat and cosmic particles. Scientists believe this could be clear evidence of a salty liquid ocean beneath the surface.

Scientists warn that over the next five billion years, there’s a tiny chance Earth could be flung from the solar system by a passing star leaving the planet to freeze in deep space, simulations suggest.

New research confirms that supernovas can become ultra-powerful particle accelerators, or "PeVatrons," but only if they explode into dense gas clouds. This explains why such events remain rare and difficult to observe directly.

Astronomers have discovered a huge, perfectly round object called Teleios emitting only radio waves from deep within our galaxy. Its mysterious shape and unknown origin have baffled scientists, who now seek deeper observations to understand it.

A new study in the journal Proceedings of the National Academy of Sciences confirms introners' role, providing the first evidence of eight interspecies transfers via horizontal gene transfer.

NISAR is a super-smart satellite with a massive 13-meter-wide radar antenna, shaped like a giant circular dish.

A new study shows the Southern Ocean could regain its carbon-absorbing ability as the ozone hole heals but only if greenhouse gas emissions drop quickly. Rising emissions could overwhelm this recovery despite ozone layer repair.

A long-term study has found that women who eat more high-quality carbohydrates and fibre during midlife are more likely to age healthily, with better mental and physical health and fewer chronic diseases later in life.

A new Ohio State University study reveals that men and women have different genes driving heart rhythm. This may explain why women have faster heart rates while men are more prone to arrhythmias like atrial fibrillation.
