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

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

These spectacular images of the Cat's Eye Nebula were created using observations from the Hubble and Euclid space telescopes.

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 distant supernova appears multiple times in the sky after its light bends through a galaxy. The strange effect may reveal clues about dark energy.

Yet what we can see with our eyes, or even with powerful telescopes, when these stars die, is only a tiny fraction of the ...

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

An international research team led by Chinese scientists has discovered new evidence about Type II-P supernovae, suggesting that some of these stellar explosions may originate from merged binary stars ...

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 ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

According to astronomers, these types of aging stars produce large amounts of cosmic dust and spread it into space.

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...
