A grid of eight distinct square panels are arranged in two rows of four against a black background. Each panel shows a bright, yellowish-orange core surrounded by thin, glowing blue rings or partial arcs that encircle the central light. Text labels containing long strings of numbers appear at the bottom of each square panel, with a larger informational title section situated underneath the entire grid.

June 9, 1988: First image of an Einstein ring

X-ray and optical composite image of IGR J11014-6103, a pulsar wind nebula, from the Chandra X-ray Observatory. A large, diffuse cloud of magenta/pink X-ray emission dominates the upper left, representing a supernova remnant. To the lower right, a smaller bright green and pink structure shows a pulsar with jets and a curved tail of X-ray emission trailing behind it, indicating rapid motion through space. Background stars are visible throughout. Credit: Chandra X-ray Center (chandra.si.edu).
