An intensive survey deep into the universe by NASA#8217;s Hubble and Spitzer space telescopes has yielded the image of the galaxy named SPT0615-JD, stretched and amplified by a phenomenon called gravitational lensing.
First predicted by Albert Einstein a century ago, the warping of space by the gravity of a massive foreground object can brighten and distort the images of far more distant background objects.
However, in this case, the gravitational field of a massive foreground galaxy cluster not only amplified the light from the background galaxy but also smeared the image of it into an arc.
Preliminary analysis suggests the diminutive galaxy weighs in at no more than 3 billion solar masses. It is less than 2,500 light-years across
The object is considered prototypical of young galaxies that emerged during the epoch shortly after the Big Bang.
