This artist’s impression shows a galactic merger in which the galaxy on the right hosts a quasar at its core; this quasar is powered by a supermassive black hole swallowing up material around it and emitting a powerful cone of radiation, piercing the other galaxy like a lance; as this radiation interacts with the galaxy on the left, it disrupts the clouds of gas and dust within, leaving behind only the smallest and densest regions; these regions are likely rendered incapable of star formation after the process.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.

This Hubble image shows NGC 2090, a spiral galaxy some 40 million light-years away in the southern constellation of Columba. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
