The Hubble Space Telescope has captured a detailed image of spiral galaxy NGC 3137, located 53 million light-years away in the constellation Antlia (The Air Pump).
This galaxy is interesting beyond its beauty. NGC 3137 belongs to the NGC 3175 galaxy group, considered an analogue of our own Local Group — the one the Milky Way calls home. Like the Local Group, the NGC 3175 group contains two large spiral galaxies — NGC 3137 and NGC 3175 — plus a number of smaller dwarf galaxies. In our Local Group, the Milky Way and Andromeda play the same "two main spirals" role. Researchers have already identified over 500 dwarf galaxy candidates in the NGC 3175 group. By studying this "neighboring family," astronomers gain insight into the dynamics of our own galactic home.
The image combines observations in six color bands. The galaxy is highly inclined from our perspective, offering a unique view of its loose, feathery spiral structure. At the center sits a black hole estimated at 60 million solar masses, surrounded by a network of fine dust clouds. Scattered across the disk are dense clusters of bright blue stars and glowing red gas clouds — signatures of young stars still forming inside their birth nebulae.
These star clusters are exactly the target: Hubble is observing them across 55 nearby galaxies to study the full cycle of stellar life — from stars still being born to ancient populations that formed in the early days of their host galaxies.
