Not surprising as they should have been there, but it shows how amazing the Spitzer is. Dwarf galaxies in our own Local Group (of galaxies) are hard to detect.

there's also a new Super Earth that was discovered outside of our solar-system that may have conditions to support life.

Wow, that's really cool. Too bad 20 light years is so far out of our reach at the moment. I'd love to see a probe get close to that.

yeh really  Cheesy I would be satisfied with just looking through the telescope they used....they probably wouldn't let me look twice though due to me drooling all over it looking into other solar systems and all   Wink Cheesy  it'll be nuts when technology has advanced so far as to be able to get a probe 20 lightyears out..

There's an observatory in Hawaii near the(14,000ft.) summit of Mauna Kea, between two volcanoes (one of which is Mauna Kea) above cloud level.  I would love the opportunity to gaze through their telescopes!!

From the article:

"We have suddenly been able to detect thousands of faint galaxies that weren't seen before," Jenkins said. Her team's study of the Coma cluster is detailed in a recent issue of the Astrophysical Journal.

So can we dispense with "dark matter" now?

On many newer telescopes, there is nothing to really look through. They are set up for cameras and digital devices, not people. Eyes can't do time exposures. etc. Wink

Actually, there is at least one site on the Net where anyone can ask for an observation to be made with some very large telescopes and they are worked in when they can be. There are other sites that organize the tens of thousands of observations already taken so the anyone wanting to see one can.

That's because I can't find the links I saved.  Here is one for small telescopes at Harvard. Small still being better than most people will ever have access to.

You need a better system.  Or something.  (More hours in the day?  A second brain?)

Thanks for the link you did find; it looks fascinating and I'm looking forward to checking it out at leisure (doesn't seem like something I can do justice to while in the middle of Cauldroning).  There's a fair chance that at some point I'll run across some mention of the others you spoke of; astronomy has been rating relatively high on my stuff-to-check-on-the-'Net priority list lately.  If I do, I'll share links.
