Stars

Some stars erupt with 'superflares' 10,000 times as powerful as solar flares from the sun. A team of "stellar detectives" are on the case and may now know why some stars are so violent.

Astronomers have discovered a flare erupting from a highly magnetic "dead star" outside the solar system for the first time. The magnetar flare lit up the entire Cigar Galaxy in gamma rays.

"Our estimated mass-loss rates can be used as a benchmark for stellar wind models and expand our limited observational evidence for the winds of sun-like stars."

The closest extreme magnetic dead star or magnetar to Earth suddenly burst back to life to give astronomers a sight of unexpected and unexplained phenomena that are unlike anything seen before.

Achoo! Baby stars "sneeze" to rid themselves of excess energy during their formation process, astronomers using the ALMA telescope array have found.

A rare massive star possessing a magnetic field could have produced its dynamo after merging with another star.

More evolved galaxies demonstrate a greater range of stellar motions compared to the orderly, circular orbits of stars like our sun in the Milky Way.

NASA's Chandra X-ray Observatory images the firework-like remnants of the great supernova of 1181.

For many years, binary star research has been as neglected as an old Tamagotchi. But now, the Gaia space telescope is leading a resurgence in interest in binary star systems.
