The one you want is this one http://imgsrc.hubblesite.org/hu/db/2007 ... ge_web.jpg.

Its the same image but has the scaling changed so you can see the arcs more clearly in the inset. I work with the guys that made it, and it is pretty cool.

Hello All

The image is only 450 million years away.

If you want to see gravitational lensing see this one

At the same time, the question is what does the bending of the light. There are some interesting view on this or is it an optical error.

You're right QEV. It is definately washed out from glare

I believe the gravitational lensing is washed out by the glare of the large elliptical in that image. If you follow the link from the APOD page, you'll come to a page with a processed version of the image where the lensing is more visible.

Even in this large image,

I too do not see any lensing effects.

I understand the principle of gravitational lensing. I can't see any gravity lens arcs in this image. Would APOD like to re-publish this image some other day and indicate the arcs with little arrows? This would help me. DEK
