At the center of the Centaurus A galaxy is a supermassive black hole that sends enormous jets out into space, which are detected by Chandra. X-rays from Chandra (red, green, blue) and IXPE (red, green, and blue); optical from ESO/MPG 2.2m (red, green, and blue)

NGC 3532 (also called the “Wishing Well Cluster”) is a cluster of middle-aged stars — about 300 million years old — that covers nearly twice the size of the full Moon on the sky. X-rays from Chandra (purple and white); optical from ESO/MPG 2.2m (red, green, and blue)

The barred spiral galaxy NGC 6872 is interacting with a smaller galaxy to the upper left. The smaller galaxy has likely stripped gas from NGC 6872 to feed the supermassive black hole in its center. X-rays from Chandra (purple); optical from Hubble (red, green, and blue)

Astronomers nicknamed this region of star formation the “Cosmic Cliffs,” which is found in the nearby Carina Nebula. X-rays from young stars in two clusters are detected by Chandra. X-rays from Chandra (purple); infrared from Webb (yellow, green, cyan, and blue)

This spiral galaxy contains a supermassive black hole and stars rapidly forming in its center. Chandra sees X-rays from gas near the massive black hole and from smaller black holes or neutron stars pulling material from companion stars.

NGC 1850 is a bright, double star cluster that lies in the Large Magellanic Cloud, a small neighbor galaxy to the Milky Way. It contains a black hole with a mass of about 11 Suns, and a companion star. No clear detection of X-rays with Chandra implies that the black hole is not quickly pulling material away from its companion.

Galaxy clusters like MACS J0035 are the largest structures in the Universe held together by gravity. They contain huge amounts of hot gas that produces X-rays seen with X-ray telescopes like Chandra. X-rays from Chandra (purple); optical from Hubble (gold)
