This revelation means scientists might have to rethink Type II supernova models, which would result in some of these cosmic ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

T CrB is a binary star system known for its predictable, though slightly irregular, eruptions, with historical records dating ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of ...

A group of stellar Sherlocks have solved the mystery of red transient objects that appear and fade in the sky, linking them ...

For the first time in history, researchers observed a dying star stripped nearly to its bare core before it exploded. This newly discovered supernova, designated SN 2021yfj, offers an unprecedented ...

The American Association of Variable Star Observers (AAVSO) announced on Thursday, June 29, 2023, that a nova eruption is expected from a binary star system called T Coronae Borealis (T CrB) sometime ...

In November 1572, a brilliant new star appeared in the constellation Cassiopeia, shining so brightly that it was visible during the day. Danish astronomer Tycho Brahe carefully documented this ...

The white dwarfs reach speeds of almost 4x needed to escape the Milky Way’s gravitational pull. Researchers at the Technion-Israeli Institute of Technology recently discovered the origin of some of ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have uncovered rare stars so fast they can escape the galaxy’s gravity altogether.
