One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

Astronomers used the James Webb Space Telescope and gravitational lensing to observe SN Eos, an ordinary supernova from the ...

This newly discovered explosion from the dawn of time is helping scientists map the chemical evolution of the first galaxies.

The scientists realized that these supernovae weren’t as nearby as they had thought, so they had zipped away from Earth ...

Supernovae, the explosive deaths of stars, are some of the universe's biggest bursts of energy and light. When they erupt, one supernova can shine even brighter than an entire galaxy. It's a fitting ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The ...

Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth's history. An analysis of the frequency of supernova explosions in the Milky Way, led by ...

The largest component of the universe is something we know almost nothing about. The best and most accurate observations that cosmologists have gathered over decades show that all the matter around us ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

When a star explodes, it sends high-energy particles out in all directions. This burst of energy can travel through space for thousands of light-years, traversing solar systems and even galaxies. The ...

Isn’t it amazing that the heavy elements we see here on Earth were created by stars going supernova? The short answer to your question is that different kinds of supernovae are caused by different ...
