Hubble’s Look at Abell 383

Lensing Galaxy Cluster Abell 383

I am always amazed by the thought of distorting the whole “local” space-time geometry by a huge gravitational force in what we know as gravitational lensing.  I’ve often wondered if we will figure out how to reconstruct the distortion to get a real view of what is behind the body responsible for the lensing.

Ah well, at any rate Hubblesite of course has the whole story and more images.  The site features a zoomable version where you can check out some of the other galaxies.

From Hubblesite:

Astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, a mere 200 million years after the Big Bang. The finding addresses questions about when the first galaxies arose, and how the early universe evolved. NASA’s Hubble Space Telescope was the first to spot the newfound galaxy. Detailed observations from the W.M. Keck Observatory on Mauna Kea in Hawaii revealed the observed light dates to when the universe was only 950 million years old; the universe formed about 13.7 billion years ago. Infrared data from both Hubble and NASA’s Spitzer Space Telescope revealed the galaxy’s stars are quite mature, having formed when the universe was just a toddler at 200 million years old. The galaxy’s image is being magnified by the gravity of a massive cluster of galaxies (Abell 383) parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing.
