'Pandora's Cluster' seen by Spitzer

This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by the Spitzer Space Telescope. The gravity of this galaxy cluster is strong enough that it acts as a lens to magnify images of more distant ...

The frontier fields: Where primordial galaxies lurk

In the ongoing hunt for the universe's earliest galaxies, NASA's Spitzer Space Telescope has wrapped up its observations for the Frontier Fields project. This ambitious project has combined the power of all three of NASA's ...

Image: 'Enterprise' nebulae seen by Spitzer

Just in time for the 50th anniversary of the TV series "Star Trek," which first aired September 8th,1966, a new infrared image from NASA's Spitzer Space Telescope may remind fans of the historic show.

An atypical protostar

At the centre of this image, captured by ESA's Herschel space observatory, is a truly peculiar cosmic object: a star named IRAS 19312+1950.

NASA team probes peculiar age-defying star

For years, astronomers have puzzled over a massive star lodged deep in the Milky Way that shows conflicting signs of being extremely old and extremely young.

Spitzer Space Telescope begins 'Beyond' phase

Celebrating the spacecraft's ability to push the boundaries of space science and technology, NASA's Spitzer Space Telescope team has dubbed the next phase of its journey "Beyond."

Orphaned protostars

Stars form as gravity contracts the gas and dust in an interstellar cloud until clumps develop that are dense enough to coalesce into stars. Precisely how this happens, however, is very uncertain, and the processes are hard ...
