- Yars’ Revenge is a video game released for the Atari 2600 in 1982. It was created by Howard Scott Warshaw, who also wrote the 2600 titles Raiders of the Lost Ark and the much-derided E.T. the Extra-Terrestrial. Yars’ Revenge was Atari’s best selling original title for the 2600.
- B-type star (Wikipedia)
B-type stars are very luminous and blue. Their spectra have neutral helium lines, which are most prominent at the B2 subclass, and moderate hydrogen lines. As O- and B-type stars are so energetic, they only live for a relatively short time. Thus, due to the low probability of kinematic interaction during their lifetime, they are unable to stray far from the area in which they formed, apart from runaway stars.
