Google celebrates the 31st Anniversary of the first use of the Canadarm in space.

This exposed image shows the path of the star Alpha Camelopardalis speeding through the sky. The big red arc is a bow shock, which NASA notes is similar to the wake in front of the bow of a ship in water.

St. Patrick’s Day has come and gone, though the Shamrock star continues to burn high in the sky. The Shamrock star is coloured green in this infrared view from NASA’s WISE lens.

Few stretches of the sky are as colourful as the Rho Ophiuchi cloud, found rising above the Milky Way in the night sky.

In Greek mythology, Orion was a hunter whose ego was so great he angered the goddess Artemis, who banished him to the sky. Here we see the head, the fuzzy red dot in the middle, of Orion, one of the most famous constellations.

This image of the nebula NGC 2174, which sits on the border of the Gemini and Orion constellations and features a beautiful image of colour and light, is why NASA calls it the Vincent van Gogh of the sky.

Here we see the constellation Cygnus, best known for looking like a swan winging its way across the night. In fact, the constellation is also commonly known as the Northern Cross, seen in the summertime skies above the world’s northern hemisphere.

According to NASA, much as dust is blown around here on earth, space dust - seen puffing all across this image - can be blown around in space by the wind and radiation emitted from stars.

This image highlights several star-forming regions all in one. There are five distinct centres of star birth in this image alone, all surrounded by gas and dust that have been heated up by nearby stars.

The cloud CG4 is seen in this WISE image, which many think, thanks to its green shape in the sky, looks like a cosmic alligator eating its way across space.

Data from NASA’s WISE allowed an artist to create this image, which depicts what a flaring black hole might look like.

The green-circled dot in this photo is an asteroid, the first known Earth Trojan asteroid, spotted in a seat of other dots, which are actually either stars or galaxies far beyond our solar system.
