Last Saturday I came across this little red dot in a Galaxy Zoo image and marked it as something someone might want to look at since it mystified me.

It seems I missed a paper published a year ago announcing a new kind of galaxy discovered with JWST, the (wait for it) Little Red Dot.

GZ just got JWST images a week or two ago and we've apparently turned up at least seven of them. No idea if this one is new, but still fun to have maybe made a minor discovery. #LittleRedDot #JWST #GalaxyZoo
