Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

A burst of light in the deep sky is doing something it should not be able to do. It looks like one supernova, but it shows up as several copies at once, scattered around two foreground galaxies. The ...

According to Einstein’s general theory of relativity, time and space are fused together in a quantity known as spacetime. The theory suggests that massive objects, like a galaxy or galaxy clusters, ...

Astronomers may be getting closer to understanding one of the biggest mysteries in cosmology: dark energy, the unknown force believed to be driving ...

The supernova SN 2025wny is hopelessly far, lying approximately 10 billion light-years from Earth. Normally, this would make it impossible for astronomers to detect. But one team got lucky. While ...

It’s challenging to make predictions, especially in astronomy. There are however, a few forecasts astronomers can depend on, such as the timing of upcoming lunar and solar eclipses and the clockwork ...
