In this image of the central region of the elliptical galaxy NGC 3862, an extragalactic jet of material moving at nearly the speed of light can be seen at the three o’clock position. The jet of ejected plasma is powered by energy from a supermassive black hole at NGC 3862’s center. A sequence of Hubble images of knots (in red, green, and blue) shows them moving along the jet over a 20-year span of observing. Astronomers were surprised to discover that the central knot (green) caught up with and merged with the knot in front of it (blue). Image credit: NASA / ESA / E. Meyer, STScI.

This illustration reveals a vast disk of gas surrounding the Wolf-Rayet star Nasty 1, shown at center. A close companion star is pulling gas from the star, shown by the bridge of bright material connecting the two stars. This act of celestial cannibalism exposes the massive star’s hot, helium core. Some of the material, however, is escaping into space, forming the huge disk. This disk structure has never been seen before around a Wolf-Rayet star. Image credit: NASA / ESA / G. Bacon, STScI.

Resembling looming rain clouds on a stormy day, dark lanes of dust crisscross the giant elliptical galaxy NGC 5128, also known as Centaurus A. The warped shape of NGC 5128’s disk of gas and dust is evidence for a past collision and merger with another galaxy. The resulting shockwaves cause hydrogen gas clouds to compress, triggering a firestorm of new star formation. At a distance of just over 11 million light-years, NGC 5128 contains the closest active galactic nucleus to Earth. The center is home for a supermassive black hole that ejects jets of high-speed gas into space, but neither the supermassive black hole or the jets are visible in this image.

This image shows Abell 3827, a massive galaxy cluster approximately 1.3 billion light years away. The blue structures surrounding the central galaxies are gravitationally lensed views of a much more distant galaxy behind the cluster. Observations of the central four merging galaxies have provided hints that the dark matter around one of the galaxies is not moving with the galaxy itself, possibly implying dark matter-dark matter interactions of an unknown nature are occurring.

This Hubble image shows ghostly green filaments, lying within galaxy 2MASX J22014163+1151237. This filament was illuminated by a blast of radiation from a quasar - a very luminous and compact region that surrounds the supermassive black hole at the center of its host galaxy. Its bright green hue is a result of ionized oxygen, which glows brightly at green wavelengths. Image credit: NASA / ESA / W. Keel, University of Alabama.
