A massive analysis of 2,884 exploding stars has uncovered new evidence that dark energy, the mysterious force accelerating ...

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

The standard model of cosmology assumes dark energy never changes. It treats it as a constant that has pushed the Universe ...

With a temperature of about 17,000 Kelvin and high luminosity, the object AT 2026abck turned out to be significantly brighter ...

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

JWST detected supernova AT 2026abck, which exploded about 1.15 billion years after the Big Bang and may be among the most ...

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.

The role of supernova winds in reionization has been reassessed using Hubble data. Astronomers have determined when galaxies ...

Research challenges long-standing assumptions about how ionising light escaped early galaxies to clear the cosmic fog during ...

When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawai'i at Mānoa ...

New observations by Webb’s NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant, NASA said in a statement.

Astronomers have watched the death of a star like never before, and it suggests there might be a new way for them to die. Last year, a space telescope called the Einstein Probe spotted a quick flash ...
