Subject: [ExI] New Hubble Deep Field Photos
The images were taken for a project called the Hubble Deep UV Legacy Survey, or HDUV, and together they total over 25 total hours of exposure time! That’s a lot for any telescope, but for Hubble, that’s deep. They cover about 100 square arc minutes of sky, about the apparent size of a large grain of sand on the tip of your finger held at arm’s length. Yet inside that tiny area are the keys to the cosmos.

Yes, it's a big universe out there!

Cool!
Minor point: square of area about 100 arc minutes would be 10 arc minutes on a side. The moon (and sun) are about 30 arc minutes across, so it is an area about a tenth of a full moon.
I set these Hubble images as my background screen. Every time I sit down here, I marvel at how cool it is to be living in the here and now.
