This was supposed to be a shot of trees in front of a setting Sun. Sometimes, though, the unexpected can be photogenic. During some planning shots, a man walking his dog unexpected crossed the ridge. The result was so striking that, after cropping, it became the main shot. The reason the Sun appears so large is that the image was taken from about a kilometer away through a telephoto lens.
Scattering of blue light by the Earth's atmosphere makes the bottom of the Sun appear slightly more red [...]
Expedition 50 Commander Shane Kimbrough of NASA is among three crew members from the International Space Station (ISS) who returned to Earth Monday, after 173 days in space, landing in Kazakhstan at approximately 7:20 a.m. EDT (5:20 p.m. Kazakhstan time).
Also returning were Flight Engineers Sergey Ryzhikov and Andrey Borisenko of the Russian space agency Roscosmos. The three touched down southeast of the remote town of Dzhezkazgan in Kazakhstan.
Kimbrough now has spent 189 days in spac [...]
Why would this cluster of galaxy punch a hole in the cosmic microwave background (CMB)? First, the famous CMB was created by cooling gas in the early universe and flies right through most gas and dust in the universe. It is all around us. Large clusters of galaxies have enough gravity to contain very hot gas -- gas hot enough to up-scatter microwave photons into light of significantly higher energy, thereby creating a hole in CMB maps.
This Sunyaev–Zel'dovich (SZ) effect has been used for [...]
Astronaut Shane Kimbrough of NASA and cosmonauts Sergey Ryzhikov and Andrey Borisenko of Roscosmos undocked from the International Space Station at 3:57 a.m. EDT to begin their journey home.
Ryzhikov, the Soyuz commander, is at the controls of the Soyuz MS-02 spacecraft. Borisenko is seated in the left seat of the Soyuz descent module and Kimbrough is in the right seat.
The crew is scheduled to land at 7:21 a.m. southeast of Dzhezkazgan, Kazakhstan.
As the Soyuz MS-02 undocked, Expediti [...]

Comet Hale-Bopp, the Great Comet of 1997, became much brighter than any surrounding stars. It was seen even over bright city lights. Away from city lights, however, it put on quite a spectacular show. Here Comet Hale-Bopp was photographed above Val Parola Pass in the Dolomite mountains surrounding Cortina d'Ampezzo, Italy. Comet Hale-Bopp's blue ion tail, consisting of ions from the comet's nucleus, is pushed out by the solar wind.
The white dust tail is composed of larger particles of dust [...]
Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait. In the false-color view, bluish Zeta Oph, a star about 20 times more massive than the Sun, lies near the center of the frame, moving toward the left at 24 kilometers per second. Its strong stellar wind precedes it, compressing and heating the dusty interstellar material and shaping the curved shock front. What set this star in motion? [...]
Two NASA astronauts and a European Space Agency astronaut headed into the weekend with a light day Friday. Meanwhile, the three cosmonauts from Roscosmos packed a Soyuz spacecraft for departure and worked on maintenance and science.
Commander Shane Kimbrough, who is returning to Earth early Monday, took it easy Friday aboard the International Space Station. He and Flight Engineers Peggy Whitson and Thomas Pesquet mainly performed light duty tasks and continued their daily exercise to stay hea [...]
