Space views that would have wowed even Capt. Kirk (pictures)
Cassiopeia like you've never seen it
In this image, a stunning view of the supernova remnant Cassiopeia A. The low-energy X-rays are colored red, medium-energy ones are green, while blue points to the highest-energy X-rays.
This level of 3D detail is the result of a collaborative effort involving NASA's Chandra X-ray Observatory and the Smithsonian Institution. The image combines data supplied by Chandra, the Spitzer Space Telescope, and ground-based installations on Earth.
Meanwhile, the Chandra X-ray Observatory, which houses a trove of spectacular space photos, is releasing never-before-seen images from its archive, which we're reproducing in this gallery. Happy viewing.

Glowing nebula near Sagittarius
This shot captures a region of glowing gas in the Sagittarius arm of the Milky Way galaxy called NGC 3576, some 9,000 light-years from Earth.

Supermassive black holes at the centers of galaxies
Giant plumes of radiation generated by 3C353, a supermassive black hole at the center of galaxy, about 410 million light-years from Earth.

Unusual -- even for the unusual
Astronomers are puzzled by the box-like appearance of 3C 397, a galactic supernova remnant with a decidedly unusual shape. Researchers think its shape has much to do with what happens when the heated remains of the exploded star collides into surrounding cooler gas.

2,400 light-years from Earth
After the explosion of a massive star in the Milky Way galaxy, the result was a supernova known as G266.2-1.2, about 2,400 light-years from our planet.

Elephant Trunk Nebula
Just for giggles, they ought to serve this image up as a Rorschach test to someone. Until then, suffice to say that 1396A, also known by its official moniker of the Elephant Trunk Nebula, is the end result when radiation and winds escaping from massive young stars impact clouds of cool gas some 2,800 light-years away.
Over the last century, scientists say that this spiral galaxy some 22 million light-years away from Earth has witnessed eight supernova explosions. Hence, its deserved nickname: the "Fireworks Galaxy."

A familiar galaxy for Earthlings?
Peering into the central region of this galaxy, known as NGC 4945 and just 13 million light-years from Earth, astronomers find a region which appears similar to our own Milky Way. One big difference: It features a far more active supermassive black hole within the white area near the top.
