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. NGC7354 (located in the constellation Cepheus) is a planetary nebulae formed when a star expelled part of its atmosphere and then maintained it as an expanding cloud of hot, ionized gas. 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. This early VLA map (one of the first made of an extended souce by the VLA) was used to show that the VLA was, in fact, successful at mapping. Success was determined by comparing the radio image to a good optical photograph.
