A Supernova Explosion Inside a Molecular Cloud
Description: W44 is one of the best example of an interacting supernova remnant with its parent molecular cloud. Radio continuum measurements indicate an elongated shell-like structure with a remarkable network of filaments and arcs across the face of this…

Tycho's Supernova Remnant (3c10)
Description: Radio emission from this remnant of the supernova of 1572 is produced by extremely energetic electrons gyrating in a magnetic field. The morphology of the spherically expanding blast wave from the supernova explosion is clearly visible. The observed…

Cassiopeia A at Dusk
Description: A radio image of Cassiopeia A, which is a young supernova remnant nearby in our Galaxy, composited with a photograph of the NRAO Very Large Array telescope at dusk. Cassiopeia A is the brightest radio source in the sky except the Sun. It is about 10…

Cassiopeia A
Description: Cassiopeia A is the remnant of a supernova explosion that occured over 300 years ago in our Galaxy, at a distance of about 11,000 light years from us. Its name is derived from the constellation in which it is seen: Cassiopeia, the Queen. A supernova…

Radio Image of the Crab Nebula
Description: The Crab Nebula, located in the constellation of Taurus, is the remnant of a supernova in 1054 AD, observed as a "guest star" by ancient Chinese astronomers. The nebula is roughly 10 light-years across, and it is at a distance of about 6,000 light…

3C58
Description: A radio image of the supernova remnant 3C58. The radio nebula is energized by a recently discovered pulsar. The beautiful filamentary structure of the nebula is brought out i this recent radio image, which was made using the NRAO Very Large Array…

VLA 90cm Image of Inner Galactic Plane
Description: This figure shows a Very Large Array 90cm image of 40 square degrees of the inner Galactic plane. This image covers about 200 times the area of the full moon and has a resolution of 42 seconds of arc (about the angular size of Jupiter viewed from…

3 color image of W30
Description: This is a 3-color image of the region surrounding the W30 supernova remnant (SNR) that is located in our Galaxy. In this image blue=Very Large Array (VLA) 90cm, red=MSX 8 microns, and green=Southern Galactic Plane Survey + VLA 20cm data. This image…

3 color image of W28
Description: This is a 3-color image of the region surrounding the W28 supernova remnant (SNR) that is located in our Galaxy. In this image blue=Very Large Array (VLA) 90cm, red=MSX 8 microns, and green=Southern Galactic Plane Survey + VLA 20cm data. This image…

Radio and X-ray Image of G21.5-0.9
Description: A radio and¡ X-ray composite image of the pulsar-powered supernova remnant, G21.5-0.9, includes data from the NRAO Very Large Array (blue) and the Chandra X-ray Observatory (red). The remnant is what remains of a supernova that exploded in our Galaxy…

Cassiopeia A (BW)
Description: Cassiopeia A (Cas A) is the remnant of the supernova event which was quite possibly witnessed by Flamsteed in AD 1680. At that time the outer layers of a massive star were ejected with high velocity, sweeping up a shell of the surrounding…

The Crab Nebula (M1)
Description: The Crab Nebula is a remnant of the supernova observed by Chinese, Japanese, and possibly natives of the southwest of the U.S.A. in 1054 AD. This image of the Crab shows the 33 millisecond pulsar as a bright point source near the center.

W50A
Description: This is 20cm total intensity map. The highly unusual compact object SS 433 appears to be located near the center of W 50, a large nonthermal galactic radio source postulated to be a SNR.

Majestic Gas Shell Revealed by the VLA
Description: What appears to be the hole of an elongated smoke ring in this National Radio Astronomy Observatory image really is an enormous, nearly empty, bubble blown into the dusty, gas disk of our Milky Way Galaxy. Such interstellar bubbles are sculpted by…

The Corpse of a Star
Description: This shell of hot gas is the remains of a star which exploded around 30,000 years ago. It is thought to be the remnant of a core-collapse supernova, which occurs when a star runs out of fuel for nuclear fusion, collapses under its own weight, and…

Supernova Remnant W28
Description: How big is a maser? That's what Mark Claussen and his collaborators are hoping to discover with this study of the supernova remnant W28. This image is one pocket of maser activity; there are several more within the region of the exploded star. The…
