A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

The new image of SNR 0509-67.5 proves that at least some Type Ia supernovae explode twice. In this model, the white dwarf forms a layer around itself of helium that it took from its companion.

A star exploded twice — First-ever image reveals its cosmic fingerprint Date: July 3, 2025 Source: ESO Summary: Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf ...

A white dwarf star around 160,000 light years away appears to have exploded twice – the first evidence astronomers have seen that such supernovae involve a double detonation.

More Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf. This vampire ...

The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view.

If this dead star orbits close enough to its living stellar companion, or if that companion swells up, then the white dwarf becomes a stellar vampire, greedily stripping material from its ...
