An Interacting Colossus

This picture, taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock).
Its unusual shape is caused by its interactions with the smaller galaxy that can be seen just above NGC 6872, called IC 4970. They both lie roughly 300 million light-years away from Earth.
From tip to tip, NGC 6872 measures over 500 000 light-years across, making it the second largest spiral galaxy discovered to date. In terms of size it is beaten only by NGC 262, a galaxy that measures a mind-boggling 1.3 million light-years in diameter!
To put that into perspective, our own galaxy, the Milky Way, measures between 100 000 and 120 000 light-years across, making NGC 6872 about five times its size.

these star trail composite images, created by stacking several photos on top of each other, were taken by justin ng from the heavily light polluted city of singapore. 
notes justin, “many people don’t believe such incredible star images can be taken here,” but “my main objective is to show you it’s possible to shoot star trails in a light polluted city.” 
he adds, "i hope everyone can do their part to stop light pollution so we can preserve our dark sky for future generations."  (see also: light pollution posts)

Boeing’s CST-100 and SpaceX’s Dragon will be the next American crew space transportation systems!
Boeing and SpaceX are expected to have their spacecraft proven and flying from U.S. soil in 2017, including completing a test flight with a NASA astronaut to the International Space Station. These companies won’t have to complete the development work by itself – NASA’s spaceflight experts in engineering and technology will work closely with the teams to make sure everything is as safe and reliable as it can be.
