I just know I'm going to want to find this again to use in a public talk, and it's fantastic so I want to share. " The Earth and Friends in Multiple Wavelengths ", by Rob Simpson ( @orbitingfrog ). Of course galaxies are my favourite, so I'm reproducing the image of M31 (the Andromeda galaxy) in here (from top left to bottom right, radio, microwave, infrared, optical, UV, Xray). And I like flowers too - so here's a geranium in optical (left) and UV. Thanks for the excellent post Rob.
