Astronomers using data from NASA's Kepler mission and ground-based telescopes recently discovered the three smallest exoplanets known to circle another star, called KOI-961.01, KOI-961.02 and KOI-961.03.

Sizing Up Exoplanets

NASA's Hubble Space Telescope's sharp view was used to look for gravitational arcs and rings which are produced when one galaxy acts as a lens to magnify and distort the appearance of another galaxy behind it.

This mosaic of images covering the entire sky was observed by NASA's WISE telescope and is part of its All-Sky Data Release. The projection used in this image of the sky is called an 'equirectangular.'

Mapping the Infrared Universe: The Entire WISE Sky -- Rectangular Format

NASA's three Great Observatories -- the Hubble Space Telescope, the SpitzerSpace Telescope, and the Chandra X-ray Observatory -- joined forces to probe theexpanding remains of a supernova, called Kepler's supernova remnant.

The Answer is Blowing in the Black Hole Wind

This artist's concept shows a view of a number of galaxies sitting in huge halos of stars. The stars are too distant to be seen individually and instead are seen as a diffuse glow, colored yellow in this illustration.

Stray Stars Scattered in Space (Artist Concept)

NASA's Spitzer Space Telescope set its infrared eyes upon the dusty remains of shredded asteroids around several dead stars. This artist's concept illustrates a 'white dwarf,' surrounded by the bits and pieces of a disintegrating asteroid.

Generations of stars can be seen in this new infrared portrait from NASA's Spitzer Space Telescope. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities.

Spitzer Reveals Stellar 'Family Tree'

NASA's Spitzer Space Telescope and the National Optical Astronomy Observatory compare infrared and visible views of the famous Orion nebula and its surrounding cloud, an industrious star-making region located near the hunter constellation's sword.

The Infrared Hunter

These images, taken by NASA's black-hole hunter, NuSTAR, are the first, focused high-energy X-ray views of the area surrounding the supermassive black hole, called Sagittarius A*, at the center of our galaxy.

This parallelogram shaped region of dust observed by ESA's Herschel Space telescope can be best described using galaxy formation models where a flat spiral galaxy collides with an elliptical galaxy becoming warped in the process.

Astronomers using NASA's Spitzer Space Telescope have spotted a 'dust factory' 30 million light-years away in the spiral galaxy M74. The factory is located at the scene of a massive star's explosive death, or supernova.

Astronomers Dig Up Treasure Trove of Galaxy Clusters

Two young binary stars may be the source of mysterious clock-like bursts of light from an object called LRLL 54361 that lies inside the star-forming region IC 348, located 950 light-years away.

Sending chills down the spine of all arachnophobes is the Tarantula nebula, seen in this image from NASA's Wide-field Infrared Survey Explorer; the nebula is the largest star-forming region known in our entire Local Group of galaxies.

WISE Spies the Tarantula Nebula

Researchers have detected the first 'exomoon' candidate -- a moon orbiting a planet that lies outside our solar system. Using a technique called 'microlensing,' they observed what could be either a moon and a planet -- or a planet and a star.

New detailed radio data from the NRAO's Jansky Very Large Array (VLA) revealed that the large perpendicular extension of UGC 10288's halo (blue) is really a distant background galaxy with radio jets.

NASA's Wide-field Infrared Survey Explorer captured this colorful image of the reflection nebula IRAS 12116-6001. This cloud of interstellar dust cannot be seen directly in visible light, but WISE's detectors observed the nebula at infrared wavelengths.
