Gravitational lensing in the heart of Pandora’s Galaxy Cluster (Abell 2744). You are looking at hundreds of trillions of stars that are 10 septillion meters away and four billion years back in time.

Someone posted this photo on Facebook long ago. Date, source is unknown for me, Google image search has failed, maybe it was scanned from a book or magazine. Any idea where is this photo from?

The Slant on Saturn’s Rings
This image from NASA’s Hubble Space Telescope shows Saturn’s Southern Hemisphere and the southern face of its rings in Infrared light.
Saturn experiences seasonal tilts away from and toward the Sun, much the same way Earth does, over the course of its 29.5-year orbit. This means that approximately every 30 years, we can catch Saturn with its rings at their maximum tilt of 27 degrees toward Earth and get the best glimpse of Saturn’s South Pole and the southern side of the planet’s rings.
