High-resolution LOFAR images used to be a rare commodity. Now we're starting to just hand them out for free! Here, enjoy this random radio galaxy :) Be sure to keep an eye on the LoTSS-HR project!

How about this for a first Bluesky post? Me sitting on top of my favorite radio telescope: LOFAR! With a blue sky in the background; very fitting right?
