Radio image of the Carina
The left image is a radio map of the famous Carina nebula in the southern sky. This is a birthplace for hot massive stars, and the nebula is produced by clouds of hot gas lit up by the stars which have formed there. The nebula radiates strongly both in radio waves, as in this image, and optically. The star Eta Carinae (discussed in another section) is quite inconspicuous in this large-scale image, lying just below the leftmost of the two very bright features near the center of the nebula. This image was made at the frequency of 843 MHz by the Molonglo Observatory Synthesis Telescope operated by the Astrophysics Department of the University of Sydney, and was provided by Jonathan Whiteoak.
