The giant elliptical galaxy in the center of this Hubble image is the most massive and brightest member of the galaxy cluster Abell 2261. Spanning a little more than one million light-years, the galaxy is about 10 times the diameter of the Milky Way Galaxy. Abell 2261 is located approximately 3 billion light-years away.

The elliptical galaxy 3C186, located about 8 billion years from Earth, is most likely the result of a merger of two galaxies. This is supported by arc-shaped tidal tails, usually produced by a gravitational tug between two colliding galaxies, identified by M. Chiaberge et al. The merger of the galaxies also led to a merger of the two supermassive black holes in their centers, and the resultant black hole was then kicked out of its parent galaxy by the gravitational waves created by the merger. The bright, star-like looking quasar can be seen in the center of the image. Its former host galaxy is the faint, extended object behind it. Image credit: NASA / ESA / M. Chiaberge, STScI.

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.

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.
