A Small Sombrero for Hubble

May 18, 2022 | Daily Space, Galaxies

IMAGE: Set against a speckled backdrop of more remote galaxies, the Little Sombrero features a bright central bulge, a thin disk full of dust, and a glowing halo of gas and stars that sprawls out into space. It is roughly 40 million light-years from Earth, 80,000 light-years-wide, and billions of years old. CREDIT: NASA, ESA, and R. de Jong (Leibniz-Institut fur Astrophysik Potsdam); Image processing: G.

NGC 7184, or the Little Sombrero Galaxy, is about the same actual size as its namesake at eighty thousand light-years across. However, the Sombrero Galaxy is twice as close, so it has a bigger angular size in our sky.

Both of the Sombrero galaxies actually resemble the Mexican hat design – at least from our edge-on perspective. This orientation allows scientists to see the massive clouds of gas and dust above and below the disk of the galaxy but also hides any spiral structure the systems might have.

This image was taken in optical and infrared using the Advanced Camera for Surveys on Hubble, to help scientists understand the stars inside the galaxy and learn how they might have evolved.
