NASA’s James Webb Space Telescope has captured a stunning new image of the Sombrero galaxy, revealing intricate details never seen before. The galaxy, also known as Messier 104 (M104), is named for its resemblance to a broad-brimmed Mexican hat. In Webb’s mid-infrared view, the galaxy’s signature glowing core is replaced by a smooth inner disk.
The sharp resolution of Webb’s Mid-Infrared Instrument (MIRI) also brings details of the galaxy’s outer ring into focus, providing insights into how dust, an essential building block for astronomical objects, is distributed. The galaxy’s outer ring, previously appearing smooth, now shows intricate clumps in the infrared for the first time. Researchers say the clumpy nature of the dust, detected as carbon-containing molecules known as polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions.
However, unlike some galaxies studied with Webb, the Sombrero galaxy is not a hotbed of star formation. Its rings produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. The supermassive black hole at the center of the Sombrero galaxy, though hefty at 9 billion solar masses, is relatively docile.
Webb’s detailed view of Sombrero
It is classified as a low luminosity active galactic nucleus, slowly consuming infalling material from the galaxy, while emitting a bright, small jet. The Sombrero galaxy is also home to around 2,000 globular clusters, which are collections of hundreds of thousands of old stars held together by gravity.
These systems serve as laboratories for astronomers to study stars, as groups of stars with the same age but varying masses and other properties provide intriguing opportunities for comparison studies. In the MIRI image, galaxies of varying shapes and colors scatter the background of space. The different colors of these background galaxies can reveal their properties, including their distances from Earth.
The Sombrero galaxy itself is around 30 million light-years away in the constellation Virgo. Stunning images like this, along with discoveries in the study of the universe, mark only the beginning for the James Webb Space Telescope. Scientists worldwide have recently applied for observation time with Webb during its fourth year of science operations, which begins in July 2025.
The James Webb Space Telescope is the world’s premier space science observatory, aiming to solve mysteries within our solar system, explore distant worlds around other stars, and probe the universe’s mysterious structures and origins. Webb is an international collaboration led by NASA alongside partners ESA (European Space Agency) and CSA (Canadian Space Agency).
