The Hat Galaxy, Messier 104, is very large; visually it is a fifth the size of the moon in a telescope. It is about 30 million light-years from Earth, in the Virgo cluster. It's called that because its shape looks like a charro hat. This spiral galaxy, cataloged as galaxy NGC 4594, looks like a song, and it highlights a dark band that seems to divide it longitudinally into two, and that is formed by immense dark clouds. The mass of the Sombrero galaxy doubles that of ours. If we could observe ours in the same way, it would look similar to Hat.
Why does the Hat Galaxy look like a hat? The reasons include the large cluster of stars towards the central area of the galaxy and the prominent dark edge of dust, which surrounds the galaxy and which, from our perspective, is seen from the side. Billions of old stars cause the great central brightness of M104, while a more detailed inspection of the ring shows intricate structures that astronomers do not yet understand. The very center of the Sombrero galaxy radiates in the electromagnetic spectrum and is thought to house a supermassive black hole.
This image was made by combining 3 CCD images, taken in approximately the primary colors; red, green and blue, with which it was possible to create an image with true colors. Each image was processed by a sensitivity variation detector and then removed the wrong regions caused by manufacturing defects and the arrival of cosmic rays to the telescope.
