The field around the cluster Abell 68 has brightened and magnified the light coming from very distant background galaxies to create what looks like a simulated alien from the classic 1970s video game "Space Invaders!" NASA reported Tuesday.
The Hubble space telescope's Wide Field Camera 3 captured the image, said astronomers at the Space Telescope Science Institute, which operates the science program for the Hubble Space Telescope.
"Like a funhouse mirror, lensing creates a fantasy landscape of arc-like images and mirror images of background galaxies," the astronomers said in a statement. "These distorted images of distant galaxies are a particularly fine example of this phenomenon."
The Abell 68 cluster is about 2 billion light-years away, and the lensed image is of galaxies far behind it.
