NGC 1300 by Steven Marx A barred spiral galaxy about 61 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across; just slightly larger than our own galaxy, the Milky Way. It is a member of the Eridanus Cluster, a cluster of 200 galaxies. [**]
The Orion Nebula complex is undoubtedly one of the most famous and beautiful areas of the entire night sky. It is easily visible to the unaided eye from a dark location as a patch of brightness surrounding Theta Orionis, the middle star in the sword of Orion the Hunter, the constellation which dominates the winter night sky. Located about 1,350 light years away, the nebula glows red predominantly from the light of hydrogen gas excited by energetic newly formed stars in the heart of the neb...
The strikingly unusual planetary nebula, NGC 6751. Glowing in the constellation Aquila like a giant eye, the nebula is a cloud of gas ejected several thousand years ago from the hot star visible in its center.
Taken by Prosper Henry, 1885. This photograph of the Ring Nebula in the constellation Lyra shows but a three-degree section of the firmament, 1,956 light-years from earth. Once a star similar to our own sun, the nebula was formed when the star exploded, releasing gasses from its outer shell into space.
Cepheus, NGC 7129 is a rosebud-shaped reflection nebula of about 10 light-years across, located some 3,330 light-years away from Earth in the northern constellation of Cepheus. It is home to a young open cluster which contains more than 130 stars less than 1 million years old, very young by astronomical standards. These stars are responsible for illuminating the surrounding bluish nebula. The young stars have blown a large bubble in the molecular cloud that once surrounded them at their birth.
