Blinded by the Light (Artist Concept)

Bright, young disks can be imaged directly by visible-light telescopes, such as NASA's Hubble Space Telescope. Older, fainter debris disks can be detected only by infrared telescopes like NASA's Spitzer Space Telescope, which sense the disks' dim heat.

The Evolution of a Planet-Forming Disk (Artist's Concept Animation)

NASA's Spitzer Space Telescope recently captured these infrared images of six older stars with known planets. The yellow, fuzzy blobs are stars circled by disks of dust, or 'debris disks,' like the one that surrounds our own Sun.

Is There Anybody Home?

This false-color image from NASA's Spitzer Space Telescope reveals hidden populations of newborn stars at the heart of the colliding 'Antennae' galaxies. These two galaxies are known individually as NGC 4038 and 4039.

GALEX 1st Light Near and Far Ultraviolet -100

Peering deep inside a cluster of several hundred thousand stars, NASA's Hubble Space Telescope has uncovered the oldest burned-out stars in our Milky Way Galaxy, giving astronomers a fresh reading on the age of the universe.

White Dwarf Stars

This artist's concept takes us on a journey to 55 Cancri, a star with a family of five known planets - the most planets discovered so far around a star besides our own.

Journey to a Star Rich with Planets (Artist Concept)

This is an ultraviolet color image of the galaxy NGC5398 taken by NASA's Galaxy Evolution Explorer on June 7, 2003. NGC5398 is a barred spiral galaxy located 60 million light-years from Earth.

These two images show 'stacked' Chandra images for two different classes of distant, massive galaxy detected with NASA's Spitzer. Image stacking is a procedure used to detect emission from objects that is too faint to be detected in single images.

Stacks of Light

This artist's concept based on data fromNASA's Spitzer Space Telescope shows delicate greenish crystals sprinkled throughout the violent core of a pair of colliding galaxies. The white spots represent a thriving population of stars of all sizes and ages.

During its one-year mission, NASA's Wide-field Infrared Survey Explorer, mapped the entire sky in infrared light. Among the multitudes of astronomical bodies that have been discovered by the NEOWISE portion of the WISE mission are 20 comets.

Comets WISE -- A Family Portrait

This artist's concept depicts a supermassive black hole at the center of a galaxy. NASA's Galaxy Evolution Explorer found evidence that black holes (once they grow to a critical size) stifle the formation of new stars in elliptical galaxies.

An Unwelcome Place for New Stars (artist concept)

Evidence from NASA's Wide-field Infrared Survey Explorer and Galaxy Evolution Explorer missions provide support for the 'inside-out' theory of galaxy evolution, which holds that star formation starts at the core of the galaxy and spreads outward.
