The James Webb Space Telescope: A Glimpse into the Cosmos

NASA’s Hubble Space Telescope observed the starburst galaxy M82 in 2006, and captured an image of a small box at the galaxy’s core, which was traced by the NIRCam instrument on NASA’s James Webb Space Telescope. The image from the Webb telescope showed red filaments, representing polycyclic aromatic hydrocarbon emission that followed the shape of the galactic wind.

In contrast to the Hubble image, where different wavelengths of light were represented by different colors – .814 microns was colored red, .658 microns was red-orange, .555 microns was green and .435 microns was blue – with filters F814W, F658N, F555W and F435W respectively. On the other hand, in the Webb image light at 3.35 microns was colored red, 2.50 microns was green and 1.64 microns was blue using filters F335M, F250M and F164N.

The collaboration between NASA, ESA, CSA, STScI and A. Bolatto from the University of Maryland helped capture these stunning images of M82 providing insight into the galaxy’s structure and dynamics.
