This ROSAT All-Sky Survey image shows a newly discovered supernova remnant
(the roughly circular emission near the top of the field) and the supernova
remnant HB-9. The star Capella is clearly visible to the left of the
image. The extended emission to the lower right from HB-9 is a cluster of
galaxies containing a thousand galaxies. The image Auriga (X-ray Colors)
displays the relative hardness of the X-rays making up this image.
