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

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 ...

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 ...

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.

A star survived the explosion that left behind Pa 30, a dandelion-shaped cloud of debris. The sharpest images yet show that ...

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 ...

CC0 Usage Conditions ApplyClick for more information. The aftermath of a stellar explosion should be a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at ...

An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint ...

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, ...

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, ...
