Close-up: Distant Galaxy IC 486 in Gemini | Hubble Space Telescop

Close-up: Distant Galaxy IC 486 in Gemini | Hubble Space Telescope

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new European Space Agency Hubble picture. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, it features a bright central bar-shaped structure where its spiral arms unfurl, wrapping around the core in a smooth, almost ring-like pattern.

Hubble’s keen eye reveals subtle variations in color across the galaxy. The pale, luminous center is dominated by older stars, while faint bluish regions in the surrounding disc trace pockets of more recent star formation. Wisps of dust thread through the galaxy’s structure, gently obscuring light and tracing regions of increased molecular gas where new stars are likely to form.

At the galaxy’s center a noticeable white glow outshines the starlight around it. This is light given off by IC 486’s active galactic nucleus (AGN), powered by a supermassive black hole more than 100 million times the mass of the Sun. Every sufficiently large galaxy hosts a supermassive black hole at its center, but these black holes can be particularly ravenous, marshalling vast amounts of gas and dust into swirling accretion discs that they feed. The intense heat generated by the orbiting disc of material generates intense radiation up to and including X-rays. These can outshine the entire rest of the galaxy. In such cases, the galaxy is known as an active galaxy, with an AGN at its center.
