Against dark rifts of interstellar dust, the ebb and flow of starlight along the Milky Way looks like waves breaking on a cosmic shore in this night skyscape. Taken with a digital camera from the dunes of Hatteras Island, North Carolina, planet Earth, the monochrome image is reminiscent of the time when sensitive black and white film was a popular choice for dimmly lit night- and astro-photography.
Looking south, the bright stars of Sagittarius and Scorpius are near the center of the frame. [...]
As they get set for next week’s arrival of the SpaceX Dragon cargo ship and a Soyuz spacecraft carrying three new crew members, Expedition 41 Commander Max Suraev and Flight Engineers Reid Wiseman and Alexander Gerst closed out the International Space Station’s workweek Friday with eye exams, cargo management and preparations for a pair of U.S. spacewalks in October.
The fourth SpaceX commercial resupply services mission remains on track for a launch from the Cape Canaveral Air Force Sta [...]
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 [...]
On Wednesday morning, Oct. 8th, not long before sunrise, the bright full Moon over North America will turn a lovely shade of celestial red. It's a lunar eclipse—visible from all parts of the USA.
"It promises to be a stunning sight, even from the most light polluted cities," says NASA's longtime eclipse expert Fred Espenak. "I encourage everyone, especially families with curious children, to go out and enjoy the event."
From the east coast of North America, totality begins at 6:25 [...]
Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists.
Astronomers looked at more than 22,000 galaxies and found that while smaller galaxies were very efficient at creating stars from gas, the most massive galaxies were much less efficient at star formation, producing hardly any new stars themselves, and instead grew by eating other galaxies.
“Technically, Andromeda will eat us be [...]
