The spider part of "The Spider and the Fly" nebulae, IC 417 abounds in star formation, as seen in this infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS).
This artists impression of super-Earth 55 Cancri e shows a hot partially-molten surface of the planet before and after possible volcanic activity on the day side.
At this time of year, holiday parties often include festive lights. When galaxies get together, they also may be surrounded by a spectacular light show.
Magnetic loops carry gas and dust above disks of planet-forming material circling stars, as shown in this artist's conception.
What might look like a colossal jet shooting away from a galaxy turns out to be an illusion. New data from the National Science Foundation's Karl G. Jansky Very Large Array (VLA), combined with an infrared view from NASA's Spitzer Space Telescope, reveals two galaxies, one lying behind the other, that had been masquerading as one.
Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASAs Spitzer Space Telescope. Some of the clouds in the region resemble the face of a monkey in visible-light images, hence the nebula's nickname: the "Monkey Head."
Volunteers using the web-based Milky Way Project brought star-forming features nicknamed "yellowballs" to the attention of researchers, who later showed that they are a phase of massive star formation.
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.
The antics of a speeding star are on display in a new image from NASA's Spitzer Space Telescope.
Massive stars can wreak havoc on their surroundings, as can be seen in this new view of the Carina nebula from NASAs Spitzer Space Telescope.
