Astronomy news update from NASA : 
These bright rims and flowing shapes look ghostly on a cosmic scale. A telescopic view toward the constellation Cassiopeia, the colorful skyscape features swept-back, comet-shaped clouds IC 59 (left) and IC 63. About 600 light-years distant, the clouds aren't actually ghosts. They are slowly disappearing though, under the influence of energetic radiation from hot,luminous star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae, the bright star just above and left in the frame. Slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the star's ultraviolet radiation recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission but more of the characteristic blue tint of dust reflected star light. The field of view spans over 1 degree or 10 light-years at the estimated distance of gamma Cas and friends.

Our new 'Word Of The Day' article update : croft , n :
An enclosed piece of land, usually small and arable and used for small-scale food production, and often with a dwelling next to it; in particular, such a piece of land rented to a farmer (a crofter), especially in Scotland, together with a right to use separate pastureland shared by other crofters. The action-adventure video game Tomb Raider, which features the fictional archaeologist Lara Croft, was launched on this day in 1996.
