The Bubble Nebula is seven light-years across — about one-and-a-half times the distance from our sun to its nearest stellar neighbor, Alpha Centauri, and resides 7,100 light-years from Earth in the Constellation Cassiopeia.
The Spider Nebula Lies About 10,000 Light-Years Away From Earth
and is a Site of Active Star Formation

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole's event horizon, where no light can escape the massive object's gravitational grip. The black hole's powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole.
Ceres' Haulani Crater, with a diameter of 21 miles (34 kilometers), shows evidence of landslides from its crater rim. Smooth material and a central ridge stand out on its floor. This image was made using data from NASA's Dawn spacecraft when it was in its high-altitude mapping orbit, at a distance of 915 miles (1,470 kilometers) from Ceres.
A sinuous feature snakes northward from Enceladus' south pole like a giant tentacle. This feature, which stretches from the terminator near center, toward upper left, is actually tectonic in nature, created by stresses in Enceladus' icy shell.
The RCW 120 bubble seen by ESA's Herschel space observatory. It lies about 4300 light-years away. A star at the centre, not visible at these infrared wavelengths, has blown a beautiful bubble around itself with the mighty pressure of the light it radiates.
This Earth observation composite image from the International Space Station captures morning sunglint and low clouds over the central Pacific Ocean. The image was put together at the Johnson Space Center in Houston, from a series of photographs taken by Expedition 47 Flight Engineer Jeff Williams on March 25, 2016.
This composite image of the Mount Brandberg Nature Reserve in Namibia, Africa was put together at the Johnson Space Center in Houston from several International Space Station images. Expedition 47 crew members photographed the middle of a vast African desert. Brandberg is Afrikaans, Dutch and German for Fire Mountain, which comes from its glowing color which is seen in the setting sun. Its highest point, the Königstein (German for 'King's Stone'), stands at 8,550 ft. above sea level.
