"SPT2349-56 is a system so extraordinary that we may have caught one of the most massive clusters under formation at a very ...

The blue shading shows the calculated extent of the protocluster, and the bluer color indicates higher density of galaxies in the protocluster. The red objects in zoom-in figures are the 12 ...

Using the JWST astronomers have dived deeper into a cosmic spiderweb called the Spiderweb protocluster located 10 billion light-years away than ever before.

The team observed a galaxy cluster about 11 billion light years ago, which is one of the ancestors of galaxy clusters we see today. JWST Near-Infrared Camera has a spatial resolution ten times ...

This vast reservoir of cool molecular gas is found in the protocluster known as SPT2349-56, located 12 billion light-years away, and could power an intense burst of star formation in the baby ...
