When you combine wide field imaging of #ESAEuclid and smaller field but 2x higher resolution imaging by #HubbleSpaceTelescope the result will be stunning: a joint look at the Cat's Eyes Nebula, NGC 6543.

This is the ESA Hubble Picture of the Month:

Au revoir Yannick!

Dear colleagues and friends,

It is with the greatest sadness that we announce the passing of Yannick Mellier, which occurred during the night between Friday and Saturday. His death leaves a huge void within the consortium and our community.

We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the previous most used survey, 2MASS, and to a bespoke ground-based image in visible light.

Here's the comparison and writeup, including tools to pan, zoom, and experiment yourself:

Not only #ESAEuclid saw the recent massive solar proton and X-ray outbreaks. Some of #ESA's other sats actually did science with it:

@WellsiteGeo@masto.ai @elsa_euclid@mastodon.social

We don't get your point. The images are perfectly aligned. The visible light images are partially intransparent for some of the stars or galaxies inside or behind the dust, respectively, which is the reason why in some of the regions there is hardly any resemblance.

In our blogpost we added a display tool so you can actually play with the data and different layers yourself:
