Recently, the James Webb Space Telescope ( JWST) took a stunning image of the star cluster known as Westerlund 2, located in ...

Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, ...

Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.

A new study shows how Milky Way chemical tracks emerge from shifting star formation and gas supply, reshaping ideas about the ...

Few stars have rattled astronomers quite like Betelgeuse, the swollen red beacon in Orion that dimmed so dramatically in ...

In addition, astrophysical observations had revealed that occasionally, white dwarfs would cool off way faster than expected.

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

Astrophysicists have achieved an eye-opening leap in understanding stellar death, capturing unprecedented, detailed images of two exploding stars that demonstrate these blasts are far more complicated ...

The bright binary star system V Sagittae will flare up multiple times before finally going supernova within the next 100 years. When it explodes, it could be visible to the naked eye even in sunlit ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every ...
