Like the 90s, binary stars are back in style
By Robert Lea published
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.

Cannibal stars at the heart of the Milky Way stay young in a gruesome way
By Robert Lea published
To remain youthful in a cosmic demolition derby around supermassive black hole Sagittarius A*, some cannibalistic stars gruesomely bathe in outer layers of their stellar victims.

Stardust particle locked in meteorite holds secrets of a star's explosive death
By Robert Lea published
A tiny grain of dust sealed within an ancient meteorite weaves together the story of the solar system's creation and reveals a much older tale of a rare star's explosive supernova death.

'Vampire' neutron star blasts are related to jets traveling at near-light speeds
By Robert Lea published
Scientists have measured for the first time the speed of jets launched by neutron star "vampires" as they feast on victim stars. The breakthrough connects these jets to thermonuclear blasts.

How are extreme "blue supergiant" stars born? Astronomers may finally know
By Robert Lea published
Scientists have discovered that the hottest and brightest stars in the cosmos, blue supergiants, are created when two smaller stars spiral together and merge, new research suggests.
