The day our Sun brought darkness

About 20 years ago, on March 13, 1989, the whole province of Quebec, Canada, suffered a blackout that by now has reached legendary proportions among astronomers and electrical engineers. Still, what made it reach this status wasn’t its proportions, but the fact that it was caused by the sun, or a solar storm to be more exact. Three days earlier,

Green visitor to pass through the solar system

Unfortunately for some, the green visitor is not an alien coming to greet us but something else, even though it also comes from far, far away. On the 24th of February the comet Lulin will pass within 61 million kilometers of Earth, thus being able to be seen with the naked eye from some locations. This is the first time

White dwarf considered the hottest ever discovered

Astronomy & Astrophysics has published spectroscopic observations of one of the hottest stars discovered so far – a white dwarf called KPD 0005+5106. The observations were made using the space-based Far-Ultraviolet Spectroscopic Explorer (FUSE), showing that the temperature can reach 200 000 K at the surface of the star. Temperatures can get so high that the emission lines are exhibited

Beta Pictoris planet could finally be imaged

Beta Pictoris (β Pic / β Pictoris) is part of a group of hot young stars that have the same age and motion through stage. It’s best known for the fact that it’s surrounded by a dusty ‘debris’ disc. This disc is a result of collisions between planetary ’embryos’ and asteroids, or other such objects. Recently, a team of French
