In 1054 AD, Chinese astronomers and others around the world noticed a new bright object in the sky. This “new star” was, in fact, the supernova explosion that created what is now called the Crab Nebula. At the center of the Crab Nebula is an extremely dense, rapidly rotating neutron star left behind by the explosion.
This colorized image of Jupiter's moon Europa is a product of clear-filter grayscale data from one orbit of NASA's Galileo spacecraft, combined with lower-resolution color data taken on a different orbit. The blue-white terrains indicate relatively pure water ice, whereas the reddish areas contain water ice mixed with hydrated salts, potentially magnesium sulfate or sulfuric acid.
The Apollo 11 Lunar Module Eagle, in a landing configuration was photographed in lunar orbit from the Command and Service Module Columbia. Inside the module were Commander Neil A. Armstrong and Lunar Module Pilot Buzz Aldrin. The long rod-like protrusions under the landing pods are lunar surface sensing probes. Upon contact with the lunar surface, the probes sent a signal to the crew to shut down the descent engine.

It was taken by Mr. Karl Bruun of Nostoca Algae Laboratory on Bainbridge Island, WA, using differential interference contrast.
Los Alamos National Laboratory, in New Mexico, US, will team up with Toshiba Corporation to use muon tomography to safely peer inside the cores of the Fukushima Daiichi reactors. The initiative could reduce the time required to clean up the disabled complex by at least a decade, and greatly reduce plant personnel exposure to radiation.
Expedition 40 Flight Engineer Alexander Gerst of the European Space Agency posted this photograph of windswept valleys in Northern Africa, taken from the International Space Station, to social media on July 6, 2014. Astronauts aboard the International Space Station (ISS) regularly photograph the Earth from their unique point of view located 200 miles above the surface.
A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas. This galactic fireworks display is taking place in NGC 4258, also known as M106, a spiral galaxy like the Milky Way. This galaxy is famous, however, for something that our galaxy doesn’t have — two extra spiral arms...

This view in the International Space Station, photographed by an Expedition 40 crew member, shows how it looks inside the space station while the crew is asleep. The dots near the hatch point to a Soyuz spacecraft docked to the station in case the crew was to encounter an emergency. This view is looking into the Destiny Laboratory from Node 1 (Unity) with Node 2 (Harmony) in the background. Destiny is the primary research laboratory ...
A stream of plasma burst out from the Sun, but since it lacked enough force to break away, most of it fell back into the Sun on May 27, 2014. A video, seen in a combination of two wavelengths of extreme ultraviolet light, covers a little over two hours. This eruption was minor, and such events occur almost every day on the sun and suggest the kind of dynamic activity being driven by powerful magnetic forces near the Sun's surface.
