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.

The tiny temperature fluctuations of the cosmic microwave background, shown here as color, trace primordial density fluctuations in the early universe that seed the later growth of galaxies. Gravitational waves from inflation are expected to produce much a fainter pattern that includes twisting B-mode polarization, consistent with the B-mode polarization pattern observed by BICEP2, which is shown here as black lines. The line segments show the polarization strength and orientation at different spots on the sky. Image credit: BICEP2 Collaboration.

This image shows the Tadpole galaxy (Arp 188), a disrupted barred spiral galaxy located 420 million light-years from our planet. Material stripped from the galaxy during its collision with a smaller galaxy (seen in the upper left corner of the larger interaction partner) forms a long tidal tail. Young blue stars, star clusters and tidal dwarf galaxies are born in the tidal debris. These objects move in a common direction within a plane defined by the orientation and motion of their tidal tail. A similar galaxy interaction might have occurred in the Local Group in the past, which could explain the distribution of dwarf galaxies in co-rotating planes. Image credit: H. Ford, JHU / M.
