This plot of data from NASA's Spitzer Space Telescope indicates that a flat, spiral galaxy called NGC 3621 has a feeding, supermassive black hole lurking within it.
This artist's concept illustrates the two types of spiral galaxies that populate our universe: those with plump middles, or central bulges (upper left), and those lacking the bulge (foreground).
This beautiful bulb might look like a Christmas ornament but it is the blown-out remains of a stellar explosion, or supernova.
These are different Spitzer Space Telescope views of the blown-out remains of a stellar explosion, or supernova.
The spectrum reveals the composition of gas and dust that were synthesized in a star explosion.
A rare, infrared view of a developing star and its flaring jets taken by NASA's Spitzer Space Telescope (right) shows us what our own solar system might have looked like billions of years ago.
This artist's animation begins by showing a dark and dusty corner of space where little visible light can escape.
A rare, infrared view of a developing star and its flaring jets taken by NASA's Spitzer Space Telescope shows us what our own solar system might have looked like billions of years ago.
This is an artist's rendition of the one-million-year-old star system called UX Tau A, located approximately 450 light-years away.
In this processed Spitzer Space Telescope image, baby star HH 46/47 can be seen blowing two massive "bubbles."
A long-lost population of active supermassive black holes, or quasars, has been uncovered by NASA's Spitzer and Chandra space telescopes.
These two images show "stacked" Chandra images for two different classes of distant, massive galaxy detected with Spitzer.
A growing black hole, called a quasar, can be seen at the center of a faraway galaxy in this artist's concept.
This plot of data from NASA's Spitzer Space Telescope reveals vast reservoirs of hot gas in a galaxy about a billion light-years away.
A big galaxy is stealing gas right off the "back" of its smaller companion in this new image from NASA's Spitzer Space Telescope.
Dusty grains - including tiny specks of the minerals found in the gemstones peridot, sapphires and rubies - can be seen blowing in the winds of a quasar, or active black hole, in this artist's concept.
This plot of data captured by NASA's Spitzer Space Telescope reveals dust entrained in the winds rushing away from a quasar, or growing black hole.
This artist's conception shows a binary-star, or two-star, system, called HD 113766, where astronomers suspect a rocky Earth-like planet is forming around one of the stars.
