Reminds me of Gigapixels of Andromeda [4K]: https://www.youtube.com/watch?v=udAL48P5NJU (listening with sound is a plus). Now imagine there are at least as many galaxies as dots of stars in these images from Hubble...

What is that bright blob/nebula thing in the upper right of the zoomable image? That is really pretty. Also, if that's closer than the galaxy how come we can't resolve individual stars in the blue haze?

NGC 604 — a gigantic gas cloud in the Triangulum Galaxy

It's really fun to zoom around.

Anybody know what the story is with the lens flare on some of the bigger/brighter objects? For some reason I expected that a Hubble image would be beyond such things.

Caused by diffraction around structural supports for the optics: https://en.wikipedia.org/wiki/Diffraction_spike

EDIT - for Hubble specifically, here’s an exploded view: https://www.spacetelescope.org/images/exploded_view1/

The spikes are caused by the arms holding the secondary mirror.
