Admire the breathtaking new images of the Sombrero Galaxy, showcasing its vast, luminous halo.
Known as Messier 104, this galaxy’s sombrero-like appearance is due to its prominent central bulge and surrounding dust trail.

Astronomers have unveiled striking new images of the Sombrero Galaxy, captured in remarkable detail. These pictures were taken using the 570-megapixel Dark Energy Camera, mounted on the Victor M. Blanco 4-Meter Telescope operated by the U.S. National Science Foundation in Chile.
The galaxy, officially termed Messier 104, resides in the Virgo constellation, approximately 30 million light-years from our planet. It is visible with small telescopes or binoculars and attracts many amateur astronomers. From Earth, it appears mostly flat, resembling a disk with a significant central bulge, which gives rise to its “sombrero” nickname.
In these latest images, the galaxy’s bright core is surrounded by about 2,000 globular star clusters, which are groups of stars held together by gravity. The edge of the disk appears darker, indicating the presence of space dust and hydrogen that have built up at the galaxy’s edge, creating a feature known as a dust lane. This region is also the primary site for star formation within the galaxy.

Messier 104 spans a distance of 50,000 light-years and harbors a supermassive black hole at its center, with a mass approximately one billion times that of our Sun. The new images reveal the galaxy’s halo, which extends to about three times the galaxy’s width. According to the U.S. National Science Foundation National Optical-Infrared Astronomy Research Laboratory (NOIRLab), “This may be the first time the halo has been captured with this level of detail and at this large a scale,” as stated in their announcement.
The Sombrero Galaxy was first observed by French astronomer Pierre Méchain in 1781 during his collaboration with Charles Messier, who was compiling a list of noncomet astronomical objects that now bears his name. Although not included in the initial publication of that list, Messier later added it manually to his personal copy. William Herschel also documented observing the galaxy in 1784. It was formally added to the Messier list in 1921, following confirmation of its discovery by astronomer Camille Flammarion.
It’s Time to Stand Up for Science
