Nasa captures a lonely galaxy from the -dark ages- of the universe 13.2billion years ago - thanks to an extraordinary trick of the lens

The galaxy is so far away - the ray of light journeyed for 13.2 billion years to get bring us this image - that by rights, we should not be able to see it.

But thanks to a universe-wide trick of the light, we have been able to glimpse back at a galaxy so far, far away, and from such a long, long time ago, that its light shone out when the universe was just 500 million years old - and still shrouded in blackness.

Nasa's Hubble satellite should not have been able to see it.

But as the galaxy passed behind a giant cluster of galaxies, the cluster acted like a giant lens magnifying the light by 15 times - and bringing us this tiny glimpse of the universe in its earliest years.

The image was released today - just as the finishing touches are put on to the mirrors of the James Webb Space Telescope, which will launch later this decade to bring back even more distant images.
