Thanks to the natural magnification from gravitational lensing, researchers have been able to study a small galaxy from when the universe was not even 1 billion years old. They saw that it is made of many clumps. This has earned the object the nickname "Cosmic Grapes" and has also challenged some of our expectations around how galaxies grow.

The object was observed by both JWST and the Atacama Large Millimeter Array ( ALMA ). It lies directly behind a large galaxy cluster with thousands of galaxies, which is much closer to us. The gravity of this cluster warps spacetime in such a way that the light of the distant galaxy is magnified and duplicated. Actually, there are five mirror imag
