Scientists have uncovered fresh clues about a distant and ancient supernova, offering a deeper look into how these powerful cosmic events evolve over time. Using advanced observations from NASA’s ...

An unusual stellar explosion matched six electron-capture predictions, opening a debate that newer observations continue to ...

Hubble observations challenge a leading theory of cosmic reionization, revealing that supernova-driven winds hinder escaping radiation while young stars may have helped illuminate the early universe.

Astronomers using the James Webb Space Telescope may have discovered a supernova erupting just 1.1 billion years after the Big Bang.

Hubble observations of nearby starburst galaxies associate faster supernova-driven winds with less escaping ionizing ...

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...

The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion. Previous images of the explosion’s remnants had also captured a sphere of long, ...

This artist’s animation shows a star going supernova. About 22 million light-years away the supernova, SN 2024ggi, exploded in the galaxy NGC 3621. Using the ESO’s Very Large Telescope, astronomers ...

Accelerating brightness pulses in SN 2024afav support a model involving a newborn magnetar and a wobbling disk. The proposed explanation uses relativistic frame-dragging to connect the changing pulse ...

Artist’s impression of a hot core—a warm cocoon of molecular gas surrounding a newborn star—discovered in a supernova remnant. Blue represents high-energy regions produced by the supernova explosion, ...
