Hubble takes awe-inspiring images of ancient galaxies

This long-exposure image of massive galaxy cluster Abell 2744, taken with the Hubble Space Telescope, is the deepest ever made of any galaxy cluster. It shows some of the faintest and earliest galaxies ever detected in space. (NASA, ESA, and J. Lotz, M. Mountain, A. Koekemoer, and the HFF Team (STScI))

Awesome!

I looked this up -- the Milky Way is so vast, if you started at one edge and traveled across it to the other at the speed of light, the journey would take 100,000 years.

Each speck in that photo is a galaxy (at least most of them are).

AND to think that the Hubble telescope was such a schemozzle for the first few years of operation, all that bother with it's "flawed" mirror, that basically resulted from those silly engineers and programmers having defined that one inch = 25 mm...

ALL for the sake of their truncated 0.4 mm per inch of measurements (which certainly adds up over a few metres !), it then took years of computer programming, millions of dollars in extra spending, and a couple of tweaks (five tuneups during space shuttle trips, actually..) to the mirror and satellite itself, to get the Hubble telescope working the way it was originally intended..

Yes...mistakes were made during the administration of President George H. W. Bush, a Republican.

I always thought it was a miracle that they were ever able to use it to take images like the one above after all the screw-ups. We really were looking at millions of dollars of carefully, but not carefully enough, -designed space junk for a while. Now I think it's worth it Smile

It's nice that they recovered it. But Bee is right in that it cost millions of dollars.
