Astronomers may have solved the mystery of how some of the brightest and hottest stars in the cosmos are born. The team, led by researchers at the Instituto de Astrofísica de Canarias (IAC), found ...

A snapshot from a hydrodynamical simulation of the interior of a star three times as heavy as our Sun, which shows waves generated by turbulent core convection and propagating throughout the star's ...

Artistic image of a binary system of a red giant star and a younger companion that can merge to produce a blue supergiant. B-type blue supergiants are very luminous and hot stars (at least 10,000 ...

Some of the brightest and hottest stars in existence may be formed by the collision of two other stars, astronomers have found. The formation of these intensely bright stars, called blue supergiants, ...

The recent detection of a gamma-ray burst from a massive blue supergiant is helping astronomers understand how the universe’s primordial stars ended their lives in cataclysmic explosions. But more ...

Astronomers have been studying the nature of blue supergiant stars for decades. Despite years of research, however, these stars have proven to be elusive and difficult to study because they live fast ...

In 1987, astronomers observed an incredible star explosion in a galaxy not too far away in the Large Magellanic Cloud. Now, researchers suggest that the famed supernova, called 1987A, was created by a ...

Eye in the sky: the TESS spacecraft has been used to identify a new class of supergiant stars. (Courtesy: NASA) A new class of stars called “fast yellow pulsating supergiants” has been identified by ...

Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our ...
