When a massive star reaches the end of its life, it explodes in a brilliant supernova explosion. The remnant of the stellar core will usually form either a neutron star or a black hole.
A group of international scientists have observed as the largest known star in the Universe tore itself apart.
A team of European researchers have pinpointed a magnetar--an unusual type of neutron star that possesses an immensely powerful magnetic field.
Thanks to the unique possibilities offered by ESO's Very Large Telescope Interferometer (VLTI), astronomers have solved a 140-year-old mystery concerning active hot stars. They indeed show that the star Alpha Arae is spinning almost on the verge of breaking and that its disc rotates the same way planets do around the Sun.
Super star clusters are groups of hundreds of thousands of very young stars packed into an unbelievably small volume. They represent the most extreme environments in which stars and planets can form. Until now, super star clusters were only known to exist very far away, mostly in pairs or groups of interacting galaxies.
