Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

Last year’s discovery of the nearest Type Ia supernova in decades — captured only 11 hours after it exploded — allowed astronomers to finally cinch the identity of the stars behind these explosions, ...

An international team of astronomers, working with researchers from University College Dublin and other institutions, has ...

Space scientists have released a jaw-dropping scenes capturing a star’s violent death — recorded over more than two and a ...

Last year's discovery of the nearest Type Ia supernova in decades – captured only 11 hours after it exploded – allowed astronomers to finally cinch the identity of the stars behind these explosions, ...

COLUMBUS, Ohio--When NASA's Transiting Exoplanet Survey Satellite launched into space in April 2018, it did so with a specific goal: to search the universe for new planets. But in recently published ...

Scientists have wondered for a long time just what causes a supernova. A new observation shows a massive star exploding, leading to the birth of a supernova. Scientists now believe they can study the ...

Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...

W49B is a barrel-shaped nebula located about 35,000 light years from Earth. The new data reveal bright infrared rings, like hoops around a barrel, and intense X-radiation from iron and nickel along ...

NASA's Transiting Exoplanet Survey Satellite (TESS) was built to search for new planets, but astronomers at Ohio State discovered that it could also observe supernovas created by exploding white dwarf ...

Researchers have published findings about a supernova observed using TESS, adding new insights to long-held theories about the elements left behind after a white dwarf star explodes into a supernova.
