SNR: Einstein IPC image of the Cygnus Loop Supernova Remnant

This image is a color version of Fig. 1 of a paper by W.H. Ku et al. In 1984, Astrophysical Journal, Vol. 278, p. 615-618 who give a detailed discussion of the interpretation (as well as a scale and orientation). The remnant is about 2.5 degrees across. In this image, North is up and East is to the right. Most other images of this remnant are flipped horizontally, so East is on the left.

Nebula: HST image of Orion Nebula

The Orion Nebula star-birth region is 1,500 light-years away, in the direction of the constellation Orion the Hunter. The image was taken on 29 December 1993 with the HST's Wide Field and Planetary Camera 2. Credit: C.R. O'Dell/Rice University, NASA
