An international group of astronomers has identified a faraway planetary system that calls into question one of the most widely accepted ideas about how planets take shape. In most planetary systems observed across the Milky Way, scientists see the same …

Scientists have used the loudest gravitational-wave signal ever recorded to put Albert Einstein’s more than 100-year-old theory of gravity to its toughest test yet — and once again, it passed. The signal, called GW250114, came from the merger of two …

It’s a cosmic roll of the dice. A major asteroid strike could cause widespread devastation and profoundly impact life on Earth, so thwarting an incoming object could be a matter of life or death. Luckily, we have a little bit …
