Horsehead of a Different Color Feature14-23_sq Spitzer Space Telescope Fri, Dec 19, 2014

Sometimes a horse of a different color hardly seems to be a horse at all, as, for example, in this newly released image from NASA's Spitzer Space Telescope. The famous Horsehead nebula makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view.

Herschel’s view of the early Universe reveals galaxy cluster fireworks Nhsc2014-014 Herschel Space Observatory Thu, Dec 18, 2014

Astronomers using ESA’s Herschel space observatory have found, for the first time, fireworks of star birth within galaxies at the dense core of a massive early Universe galaxy cluster. This frenzy of star formation reveals the young lives of now “red and dead” elliptical galaxies and gives new clues to the evolution of some of the largest structures in the Universe.

Follow the Dust to Find Planets Feature14-21_sq Spitzer Space Telescope Mon, Nov 10, 2014

Researchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory, in which NASA is a partner.

NASA Rocket Experiment: Universe is Brighter Than We Thought Partner089_sq Spitzer Space Telescope Thu, Nov 06, 2014

A NASA sounding rocket experiment has detected a surprising surplus of infrared light in the dark space between galaxies, a diffuse cosmic glow as bright as all known galaxies combined. The glow is thought to be from orphaned stars flung out of galaxies.
