Betelgeuse, one of the brightest stars in the constellation Orion, has long fascinated astronomers because it is nearing the ...

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 ...

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

In 2019, Betelgeuse mysteriously dimmed by a third of its brightness. Hubble data reveals the cause: a massive Surface Mass ...

This supernova is one for the record books. A mammoth star explosion known as SN2016aps, which occurred in a galaxy about 3.6 billion light-years from Earth, is the brightest supernova ever seen, a ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, SN 2024ggi, revealed a surprisingly olive-shaped blast when studied with ...

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...

An international research team led by Chinese scientists has discovered new evidence about Type II-P supernovae, suggesting ...
