Nebulae Photo Gallery

Helix Nebula

The familiar eyeball shape of the Helix Nebula shows only two dimensions of this complex celestial body. But new observations suggest it may actually be composed of two gaseous disks nearly perpendicular to each other.

Henize 206 Nebula

This false-color infrared image captured by the Spitzer Space Telescope shows the Henize 206 Nebula, a massive cloud of gas and dust in which hundreds and possibly thousands of new stars have formed over the last ten million years. The nebula, located just outside the Milky Way in a galaxy called the Large Magellanic Cloud, offers astrophysicists a celestial ringside seat on the death and rebirth of stars.


Eskimo Nebula

The Eskimo Nebula got its name because the astronomer who discovered it in 1787 thought it looked like a person's head surrounded by a parka hood. This highly detailed image taken in 2000 by the Hubble Space Telescope, however, reveals a much more complex structure, one which astrophysicists are still trying to explain.


Rosette Nebula

An infrared image of the Rosette Nebula shows super-hot O stars (blue dots inside spheres) amid a torrent of gas and dust (green and red). This star-forming nebula, which lies 5,000 light-years away in the constellation Monoceros, is named for its rosebud-like shape when seen using only optical light.


Orion Nebula

This true-color mosaic captured by the Hubble Space Telescope shows a small portion of the Orion Nebula. The image provides unprecedented detail of the nebula, revealing elongated objects oriented on the region's brightest stars, rapidly expanding plumes of material around young stars, and protoplanetary disks.
