Comments on: The Last WFPC2 Image from Hubble http://blogs.discovermagazine.com/cosmicvariance/2009/05/13/the-last-wfpc2-image-from-hubble/ Random samplings from a universe of ideas.

The idea is that with HST, you can resolve individual stars within galaxies (provided they're close -- less than 4 Mpc or so). The distribution of colors and magnitudes of those stars tell you when the stars were born, and with what metal content. Understanding how such things vary with position within a galaxy, and from galaxy-to-galaxy, is a useful complement to the in situ studies people do at high redshift.

Coolstar: I think Julianne's image has not been reduced/posted yet, the one I see on this page is a link to the wikipedia page on IC5152, and the image was taken June 19th, 2008. Julianne,

What scientific content are you seeking to extract from the image of IC5152?

Coolstar: I think Julianne’s image has not been reduced/posted yet, the one I see on this page is a link to the wikipedia page on IC5152, and the image was taken June 19th, 2008.

The dwarf galaxy is somehow stylishly elegant while the planetary is just garish. I'd be stoked about having the last image too. Someone should do a citation search comparing WFPC2 to other productive instruments. My money would be on WFPC2. Aesthetically, I actually prefer Julianne’s image of IC5152 to the planetary.

I was disappointed with the final release image; it's OK, but I've come to expect a lot more from PNe observations! But then, we'll be seeing WF3 images soon enough, and those will rock the house. That’s very cool, congrats.

Big-science "lasts" are a slightly morbid but interesting topic. My personal one: my dissertation used the very last protons ever accelerated by Fermilab's original Main Ring. Cool!

Still wish it had been NGC6441 instead... I wanted that data. Congratulations, again!
