On November 25, 2024, NASA unveiled a spectacular image of the Sombrero galaxy, taken using the James Webb telescope. This image, taken in infrared light, offers a fascinating new perspective on this iconic galaxy, also known by its scientific name, Messier 104 (M104).
Located about 30 million light years away in the constellation Virgo, the galaxy gets its nickname because of its resemblance to a Mexican sombrero. This new observation, carried out using James Webb’s MIRI (Mid-Infrared Instrument), is distinguished by unprecedented precision, surpassing previous images obtained by the Hubble telescope, which operated mainly in visible light.
A galaxy transformed by infrared
Infrared images reveal previously inaccessible details. The central core, which glowed intensely in visible light, now appears as a smooth disk. The outer ring, which appeared uniform in images from the Spitzer infrared telescope, now reveals a complex structure, composed of dust and carbon molecules. These discoveries suggest star formation activity within this ring.
In the background, the view captured by James Webb also shows many distant galaxies, each with varying shapes and colors. These observations enrich our understanding of the universe, making it possible to determine the distances and characteristics of these distant objects.
A treasure for future research
This image is not only a visual feat: it constitutes a valuable source of data for astronomers. The information collected using the infrared spectrum makes it possible to study the chemical composition of dust and gases within the galaxy. This paves the way for in-depth research into galaxy dynamics and star formation processes. Every detail revealed by James Webb helps elucidate the mysteries of galactic evolution in the universe.
A popularity that does not weaken
The James Webb Telescope continues to be at the heart of astronomical research. For the year 2025, no less than 2,377 study proposals were submitted to the observatory before the deadline of October 15, 2024. The projects cover a wide range of themes, from distant galaxies to exoplanet systems.
In the meantime, astronomers and astronomy enthusiasts welcome this new technical feat. The Sombrero Galaxy, once again, captivates the eye and stimulates scientific curiosity. Hats off to the team that helped reveal this new face of the universe!
