Life and Death Intermingled
In what may look to some like an undersea image of coral and seaweed, a new image from NASA's Spitzer Space Telescope is showing the birth and death of stars. In this view, infrared data from Spitzer ...

Galaxies in Hiding
There are nearly 200 galaxies within the marked circles in this image from NASA's Spitzer Space Telescope. These are part of the Perseus-Pisces supercluster of galaxies located 250 million light-years...

Infrared Iris
This cloud of glowing gas is the Iris nebula, as seen in infrared light by NASA's Spitzer Space Telescope. The main cluster of stars within the nebula is called NGC 7023. It lies 1,300 light-years awa...

Galactic Wheels within Wheels
How many rings do you see in this new image of the galaxy Messier 94, also known as NGC 4736? While at first glance one might see a number of them, astronomers believe there is just one. This image wa...

Taken Under the 'Wing' of the Small Magellanic Cloud
The tip of the "wing" of the Small Magellanic Cloud galaxy is dazzling in this new view from NASA's Great Observatories. The Small Magellanic Cloud, or SMC, is a small galaxy about 200,000 light-years...

Vega - Two Belts and the Possibility of Planets
Astronomers have discovered what appears to be a large asteroid belt around the bright star Vega, as illustrated here at left in brown. The ring of warm, rocky debris was detected using NASA's Spitzer...

Probing Brown Dwarf Layers
This graph shows the brightness variations of the brown dwarf named 2MASSJ22282889-431026 measured simultaneously by both NASA’s Hubble and Spitzer space telescopes. As the object rotates every 1.4 ho...
