This Day:

Hubble is still going strong:). Gazing deep into the sky, it has located a school of galaxies located within a tiny region of space. They are all very different: some are large, some are small. Some are old, and some are new. Most of them have never been seen before, until now:).

A handful of large fully formed galaxies are scattered throughout the image. These galaxies are easy to see because they are relatively close to us. Several of the galaxies are spirals with flat disks that are oriented edge-on or face-on to our line of sight, or somewhere in between. Elliptical galaxies and more exotic galaxies with bars or tidal tails are also visible.
Many galaxies that appear small in this image are simply farther away. These visibly smaller galaxies are so distant that their light has taken billions of years to reach us. We are seeing these galaxies, therefore, when they were much younger than the larger, nearby galaxies in the image. One red galaxy to the lower left of the bright central star is acting as a lens to a large galaxy directly behind it. Light from the farther galaxy is bent around the nearby galaxy's nucleus to form a distorted arc.
This image is a composite of multiple exposures of a single field taken by the Advanced Camera for Surveys. This image took nearly 40 hours to complete and is one of the longest exposures ever taken by Hubble:):).

You're talking of gravitational lensing right?

PS : I visit your blog/site everyday, am just too lazy to leave comments. So keep up the good work dude.

Not really:). None of the galaxies in the picture look alike, so they are not pictures of the same galaxy appearing twice/thrice as happens with gravitational lensing. It is just a nice picture, thats all :).

Thanks for visiting!

I know:(. So much is uselessly spent.. I wish someone tried to come up with solutions to keep Hubble up there:(.

Thanks for that link:). India and USA share so many common traits (multi-cultural, multi-ethnic, tolerant, democratic, free-market) that they are natural allies. One has to look beyond the cold-war issues, and give the whole thing a fresh start.
I also think it would be wrong for USA to have a relation with India, only as a counter-weight to China. It is fair neither to India, nor to India-China or USA-China relationships, each of which have their own complex dynamic. History has taught us that whenever we make alliances not on what is common between us, but who our enemies are, we are only creating problems for the future.
