Millions of galaxies populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey, a portion of which is shown here. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away.

Astronomers were surprised to see these data from NASA's Spitzer Space Telescope in January 2013, showing a huge eruption of dust around a star called NGC 2547-ID8. In this plot, infrared brightness is represented on the vertical axis, and time on the horizontal axis.

The destructive results of a mighty supernova explosion reveal themselves in a delicate blend of infrared and X-ray light, as seen in this image from NASAs Spitzer Space Telescope and Chandra X-Ray Observatory, and the European Space Agency's XMM-Newton.

Something appears to be peering through a shiny red mask, in this infrared image from NASA's Spitzer Space Telescope. The mysterious blue eyes are actually starlight from the cores of two merging galaxies, called NGC 2207 and IC 2163. The mask is the galaxies' dusty spiral arms.

This new view of the Orion nebula highlights fledgling stars hidden in the gas and clouds. It shows infrared observations taken by NASA's Spitzer Space Telescope and the European Space Agency's Herschel mission, in which NASA plays an important role.

Dense envelopes of gas and dust surround the fledging stars known as protostars, making their detection difficult until now. The discovery gives scientists a window into the earliest and least understood phases of star formation.

This image of asteroid 2011 MD was taken by NASA's Spitzer Space Telescope in Feb. 2014, over a period of 20 hours. The long observation, taken in infrared light, was needed to pick up the faint signature of the small asteroid (center of frame).

This image shows two clusters of galaxies colliding with one another, the smaller one being known as the Bullet Cluster. NASA's Spitzer Space Telescope obtained these observations during the telescope's warm mission phase, following the depletion of its liquid coolant in 2009.

There are nearly 200 galaxies in this image from NASA's Spitzer Space Telescope. These are part of the Perseus-Pisces supercluster of galaxies located 250 million light-years away. Normally, galaxies beyond our Milky Way are hidden from view when they happen to fall behind the plane of our galaxy. This is due to foreground dust standing in the way.

This infrared data from NASA's Spitzer Space Telescope called a spectrum tells astronomers that a distant gas planet, a so-called "hot Jupiter" called HD 189733b, might be smothered with high clouds. It is one of the first spectra of an alien world.

This graph of infrared data from NASA's Spitzer Space Telescope tells astronomers that a distant galaxy called IRAS 08752+3915 is experiencing a storm of tiny crystals made up of silicates. The crystals are similar to the glass-like grains of sand found on Earth's many beaches.

This NASA Spitzer Space Telescope image reveals a glowing stellar nursery within a dark globule in IC 1396 that is opaque in visible light. Spitzer pierces through the obscuration to reveal the birth of new protostars, or embryonic stars, and young stars never before seen.

This infrared image from NASA's Spitzer Space Telescope has captured a nearby spiral galaxy that resembles our own Milky Way. The galaxy, known as NGC 7331 and sometimes referred to as our galaxy's twin, is found in the constellation Pegasus at a distance of 50 million light-years.
