Dear Eos:
Greetings from 4.6 billion years ago!
This is the first deep field image from the James Webb Space Telescope, centered on the galaxy cluster SMACS 0723. Beyond the stars of the Milky Way (which have 8 points) are thousands of galaxies, trillions of stars, and a vast, untold number of planets. This image would fit within a grain of sand held at arm’s length against the night sky—truly, science is wide open.
