The region of space dominated by the Solar magnetosphere is the heliosphere, which spans much of the Solar System. Along with light, the Sun radiates a continuous stream of charged particles (a plasma) called the solar wind.
One of the Crew-8 members, NASA astronaut Matthew Dominick, even captured a striking video of his own of Milton from the mission's Endeavor Dragon capsule still docked at the space station.
NASA astronaut Bob Hines tweeted on Aug. 17, sharing a collection of photos taken from the International Space Station. The photos showed the Northern lights – bands of green light topped with ...
The south polar region seems to be darker than the north polar region, but there is a high-albedo region in the southern hemisphere that may be a regional nitrogen or methane ice deposit.

HD 21749 c is a planet described as "likely rocky", with about 89% of Earth's diameter and orbits the K-type main sequence star HD 21749 in about 8 days. The planet's surface temperature is estimated to be as high as 427 °C. Both known planets in the system, HD 21749 b and HD 21749 c, were discovered by TESS. HD 21749 c represents the 10th ...
This initiative has received support from NASA, the National Science Foundation, and MTU. The images are sometimes authored by people or organizations outside NASA, and therefore APOD images are often copyrighted, unlike many other NASA image galleries. [4] When the APOD website was created, it received a total of 14 page views on its first day.
The first satellites designed for long term observation of the Sun from interplanetary space were NASA's Pioneers 6, 7, 8 and 9, which were launched between 1959 and 1968. These probes orbited the Sun at a distance similar to that of Earth, and made the first detailed measurements of the solar wind and the solar magnetic field.
The distance separating the planet and its star is just 7% of the distance between Earth and the Sun, and the planet receives 1.6 times more energy from its star than Earth does from the Sun.
