Researchers seek to understand how regions of ‘cosmic web’ influence behavior of galaxies

The red region (left) shows the shell enclosed by the Baryon Acoustic Oscillation, with individual galaxies depicted as luminous tiny specks. The blue filaments show the greater Cosmic Web, with previously known features like Laniākea highlighted.

Vast bubble of galaxies discovered, given Hawaiian name

The power of JWST to map galaxies at high resolution and at longer infrared wavelengths than Hubble allows it look through dust and unveil the underlying structure and mass of distant galaxies. This can be seen in these two images of the galaxy EGS23205, seen as it was about 11 billion years ago. In the HST image (left, taken in the near-infrared filter), the galaxy is little more than a disk-shaped smudge obscured by dust and impacted by the glare of young stars, but in the corresponding JWST mid-infrared image (taken this past summer), it’s a beautiful spiral galaxy with a clear stellar bar.
