Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but they came close enough to leave a permanent mark on the thin mist of gas that ...

The CosmicWatch device costs only $100 to make, making it accessible for both high school students and spacecraft operators.

The Vera C. Rubin Observatory is set to detect millions of exploding vampire stellar remnants called "white dwarfs," shedding ...

Dark matter, if it exists, is probably in the latter category. If hypothetical weakly interacting massive particles (WIMPs) are real, their collisions with regular matter may have left fossil traces ...

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 ...

Some exploding stars (supernovae) experience two blasts. These double explosions occur in white dwarf stars. The explosions create two distinct calcium-rich layers. This discovery helps explain how ...

NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, shedding light on everything from dark energy to black hole physics. Its ...

Many moonless evenings the next two weeks are a great time for viewing the best of the summer stars. You may also see the remarkable occurrence of two exploding stars at once, plus the possibility of ...

A rare supernova let scientists glimpse a star's interior, revealing a dense silicon-sulphur shell and unexpected helium that should have vanished earlier. (Nanowerk News) An exploding star has given ...
