This plot shows that a pulsar, the remnant of a stellar explosion, is surrounded by a disk of its own ashes. The disk, revealed by the two data points at the far right from NASA's Spitzer Space Telescope, is the first ever found around a pulsar.

Circle of Ashes

The Tadpole galaxy is the result of a recent galactic interaction in the local universe. These spectacular images were taken by NASA's Spitzer Wide-area Infrared Extragalactic (SWIRE) Legacy project.

A SWIRE Picture is Worth Billions of Years

Evidence for this possible belt was discovered by NASA's Spitzer Space Telescope when it spotted warm dust around the star, presumably from asteroids smashing together. This is an artist's concept.

Band of Rubble (Artist Concept)

This artist's concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury. NASA's Spitzer found evidence that a high-speed collision of this sort occurred a few thousand years ago around a young star.

Planetary Demolition Derby

This artist's concept shows a Super Venus planet on the left, and a Super Earth on the right. Researchers use a concept known as the habitable zone to distinguish between these two types of planets, which exist beyond our solar system.

Toxic Wasteland or Lush Paradise? (Artist Concept)

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.

Star System Bonanza (Illustration)

The tightly packed system, named Kepler-444, is home to five small planets in very compact orbits. The planets were detected from the dimming that occurs when they transit the disk of their parent star, as shown in this artist's conception.

Kepler-444 Planetary System (Artist Concept)

Black holes are tremendous objects whose immense gravity can distort and twist space-time, the fabric that shapes our universe as this chart from NASA's NuSTAR and ESA's XMM-Newton telescope illustrates.

How to Measure the Spin of a Black Hole (Artist's Concept)

This artist's concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface.

A Tale of Two Worlds: Silicate Versus Carbon Planets (Artist Concept)

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)

One of Planck's first images is shown as a strip superimposed over a two dimensional projection of the whole sky as seen in visible light.

Planck's First Glimpse at the Universe

This map of the entire sky was captured by the European Space Agency's Planck mission - The band running through the middle corresponds to dust in our Milky Way galaxy.

Astronomers Dig Up Treasure Trove of Galaxy Clusters

NASA's Wide-field Infrared Survey Explorer highlights the Small Magellanic Cloud, a small galaxy about 200,000 light-years away. Located in the constellation Tucana, the Small Magellanic Cloud looks like a wispy cloud encircling the south celestial pole.

WISE's View of a Wispy Cloud

This artist's concept shows a supermassive black hole at the center of a remote galaxy digesting the remnants of a star.

Beyond the Veil

The Sculptor galaxy, or NGC 253, is seen in a rainbow of infrared colors in this mosaic by NASA's Wide-field Infrared Survey Explorer. The Sculptor galaxy can be seen by observers in the southern hemisphere with a pair of good binoculars.

The Many Infrared 'Personalities' of the Sculptor Galaxy

Researchers are brewing up icy, organic concoctions in the lab to mimic materials at the edge of our solar system and beyond. The lab is shown at right, and a very young solar system, with its swirling planet-forming disk is at left.

Ice from the Solar System's Edge (Artist's Concept)

This artist's concept shows a hypothetical 'rejuvenated' planet,a gas giant that has reclaimed its youthful infrared glow. NASA's Spitzer Space Telescope found tentative evidence for one such planet around a dead star, or white dwarf, called PG 0010+280.

Hypothetical 'Rejuvenated' Planets (Artist's Concept)

NASA's Wide-field Infrared Survey Explorer has uncovered the coldest brown dwarf known so far (green dot in very center of this infrared image). WISE 1828+2650 is located in the constellation Lyra. The blue dots are a mix of stars and galaxies.

Reigning Title-Holder for Coldest Brown Dwarf

This artist's concept based on data found by NASA's Spitzer Space Telescope shows upsilon Andromedae b, a hot gas giant that whips around its star every 4.6 days. Because it is so close to its star, it is tidally locked.

Planetary Hot Spot Not Under the Glare of Star (Artist Concept)

A star's spectacular death in the constellation Taurus was observed on Earth as the supernova of 1054 A.D. This composite image uses data from three of NASA's Great Observatories. The Chandra X-ray, Hubble Space, and Spitzer Space Telescope.

Dead Star Creates Celestial Havoc

A Neptune-size planet with a clear atmosphere is shown crossing in front of its star in this artist's depiction. Such crossings, or transits, are observed by telescopes like NASA's Hubble and Spitzer to glean information about planets' atmospheres.

This still from an artist's animation flies through the Kepler-20 star system, where NASA's Kepler mission discovered the first Earth-size planets around a star beyond our own. The system is jam-packed with five planets.

An Unusual Planetary System (Artist's Concept)

NuSTAR has added a new twist to the mystery of ultraluminous X-ray sources (ULXs) by showing that one of the ULXs in M82, called M82 X-2, is not a black hole but a pulsar.

This diagram illustrates two similar star systems, HD 95086 and HR 8799. Evidence from NASA's Spitzer Space Telescope has pointed to the presence of two dust belts in each system.
