From Astronomy Picture of the Day for 6/11/19.

The Pinwheel Galaxy is more properly designated M101.

Here it is seen in an amalgamation of colour-coded photos taken in X-ray (purple,) ultra-violet (blue,) visible light (yellow) and infra-red (red) from the Chandra X-ray Observatory, the Galaxy Evolution Explorer, the Hubble Space Telescope and the Spitzer Space Telescope respectively.

Given it looks like a spinning Catherine wheel firework they should have posted this a day earlier.

Then again, they’re USian, they probably wouldn’t know the significance of the 5<sup<th November in the UK.
