This low-density region caused the supernova to expand faster than normal. NASA's IXPE studied supernova RCW 86, enhancing prior observations of the remnant Chandra Observatory revealed a low-density ...

This unique interaction explains why the remnant appears much older than it is, finally reconciling ancient observations with modern X-ray data to solve this celestial mystery. For nearly twenty ...

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

Oscillations in the brightness of a ‘superluminous’ supernova reveal it to be powered by a magnetized neutron star that distorts the orbit of surrounding gas. Superluminous supernovae are often more ...

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an ...

Using the James Webb Space Telescope (JWST), a team of astronomers has found the earliest known supernova, one which exploded when the universe was just 730 million years old. This observation ...
