About this Image

In 1977, the newly functioning VLA was used to map the radio emission from shells of hot gas, known as planetary nebulae, ejected from dying stars. The intensity of the radiation is denoted by color, which ranges from red (brightest) to blue (faintest). The effective angular size of the array's beam is shown in the inset.

Investigator(s):  R.M. Hjellming, R.C. Bignell, and B. Balick
