This image shows the first-ever map of the surface of an exoplanet, or a planet beyond our solar system. Showing temperature variations across the cloudy tops of a gas giant called HD 189733b, the infrared data is taken by NASA's Spitzer Space Telescope.

First Map of Alien World (animation)

This artist's animation shows a typical young galaxy, teeming with hot, newborn stars and exploding supernovas. The supernovas are seen as white flashes of light.

Fires of Galactic Youth (Artist Animation)

This artist's concept illustrates how planetary systems arise out of massive collisions between rocky bodies. NASA's Spitzer Space Telescope show that these catastrophes continue to occur around stars even after they have developed full-sized planets.

This image from NASA's Wide-field Infrared Survey Explorer, shows four galaxies in the Virgo cluster: Messier 59, Messier 60, NGC 4647, and NGC 4638. It also shows the tracks of three asteroids, which appear in this image as trails of green dots.

When astronomers first looked at images of a supernova remnant called Cassiopeia A, captured by NASA's NuSTAR. The mystery of Cassiopeia A (Cas A), a massive star that exploded in a supernova more than 11,000 years ago continues to confound scientists.

ESA's Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with a third cluster, will smash together in several billion years.

This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars. The planet's 66-day orbit is tilted 2.5 degrees with respect to the plane of the binary stars' orbit.

This image of the microwave sky was synthesized using data spanning the range of light frequencies detected by ESA's Planck. A vast portion of the sky is dominated by the diffuse emission from gas and dust in our Milky Way galaxy.

NASA's Spitzer Space Telescope has detected the solid form of buckyballs in space for the first time. To form a solid particle, the buckyballs must stack together, as illustrated in this artist's concept showing the very beginnings of the process.

The third closest star system to the sun, called WISE J104915.57-531906, center of large image, which was taken by NASA's WISE. It appeared to be a single object, but a sharper image from Gemini Observatory, revealed that it was binary star system.

This photograph from NASA's Spitzer Space Telescope shows the young star cluster NGC 2362. By studying it, astronomers found that gas giant planet formation happens very rapidly and efficiently, within less than 5 million years.

Baby Jupiters Must Gain Weight Fast

NASA's Hubble Space Telescope has imaged an unusual edge-on galaxy, revealing remarkable details of its warped dusty disc and showing how colliding galaxies trigger the birth of new stars.

This artist's concept demonstrates how a dusty planet-forming disk can slow down a whirling young star, essentially saving the star from spinning itself to death. Evidence for this phenomenon comes from NASA's Spitzer Space Telescope.

Astronomers have uncovered patterns of light that appear to be from the first stars and galaxies that formed in the universe. The light patterns were hidden within a strip of sky observed by NASA's Spitzer Space Telescope.

The green dot in the middle of this image might look like an emerald amidst glittering diamonds, but is a dim star belonging to a class called brown dwarfs; it is the first ultra-cool brown dwarf discovered by NASA's Wide-field Infrared Survey Explorer.
