Active Galaxies

News & Articles

A pair of interacting galaxies. The larger of the two galaxies is slightly right of center, and composed of a hazy, bright, white center and a ring of gaseous filaments, which are different shades of red and orange. Toward the bottom left and bottom right of the ring are filaments of gas spiraling inward toward the core. At the top left of the ring is a noticeable gap, bordered by two large, orange pockets of dust and gas. The smaller galaxy to its left is made of hazy white gas and dust, which becomes more diffuse farther away from its center. To this galaxy’s bottom left, there is a smaller, more diffuse gas cloud that wafts outward toward the edges. Many red, orange, and white galaxies are spread throughout, with some hazier in composition and others having more defined spiral patterns.

This is an artist's depiction of a pair of active black holes at the heart of two merging galaxies. They are both surrounded by an accretion disk of hot gas. Some of the material is ejected along the spin axis of each black hole. Confined by powerful magnetic fields, the jets blaze across space at nearly the speed of light as devastating beams of energy.
