When stars die, they spread the elements they’ve created in their cores out to space. But other objects and processes in space also create elements. Eventually, that “star stuff” scatters across the ...

A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a ...

For the first time, scientists determined the shape of a supernova's shock front as it burst through the surface of a dying ...

Scientists have turned to artificial intelligence (AI) to better understand why some dead stellar remnants called white dwarf stars explode. These energetic explosions, called Type Ia supernovas, ...

The exploded star Tycho, called the Tycho Supernova. (It's not the star recently observed exploding, but a past supernova event.) Credit: NASA / CXC / RIKEN and GSFC / T. Sato et al. / Optical: DSS ...

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

The James Webb Space Telescope and other observatories witnessed a massive explosion in space that created rare chemical elements, some of which are necessary for life. The explosion, observed on ...

All we are is cosmic dust in the wind. When dying red giant stars throw off material, dust particles form; those particles are later destroyed by supernova blast waves, which move through space at ...

If you ever wondered what would happen if you were to throw a black hole at a star, well astronomers now have an answer: it goes "boom" in a truly distinctive way. Researchers have spotted an ...
