Hubble shows 2 galaxies that are just losing it

Ram pressure is the pressure exerted on a body when it passes through a fluid medium; this causes a drag force that is exerted on the body. The same pressure appears when a galaxy is moving through an intergalactic gas, and in this case, the ram pressure can sweep a significant part of the intergalactic [...]

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 [...]
