Can any nearby supernova cause a mass extinction?
The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a small fraction of a supernova's power, they are extremely dangerous. But they're not going to disintegrate ...

Observations detect a companion star to T Coronae Australis
Using the Very Large Telescope Interferometer (VLTI), an international team of astronomers has observed a young Herbig Ae-type star known as T Coronae Australis. As a result, they found that the star has a companion separated ...
Wolf-Rayet 104 'pinwheel' star reveals a surprise (and some relief)
A recent study reveals that the famous Wolf-Rayet 104 "pinwheel star" holds more mystery but is even less likely to be the potential "death star" it was once thought to be.

Four small planets discovered around one of the closest stars to Earth—an expert explains what we know
Barnard's Star is a small, dim star of the type that astronomers call red dwarfs. Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it is too faint to ...
