Look for the crescent moon, should the clouds part tonight.
Beside it Venus will shine bright, and past them will fly the International Space Station and the space shuttle Atlantis, on its final flight.
"The show begins at sunset when Venus and the moon emerge from the twilight in close proximity," says NASA. "The moon will be exquisitely slender, a 5-percent crescent on Saturday ... and a slightly fatter, 10-percent crescent on Sunday.... Between the horns of the crescent, a ghostly image of the full moon can be seen. That's 'Earthshine' — the light of our own planet reflected back toward us...."
Also at dark comes the space station, "shining as brightly as Venus herself," says NASA, which by city offers a SkyWatch website for tracking the orbiters. The shuttle just caught up and docked with the space station today, NASA says.
Never miss a local story.
Only three shuttle flights remain. In Atlantis's 12-day mission, the crew will deliver supplies, spare parts, a Russian research module and a European robotic arm. During three spacewalks totaling 20 hours, the astronauts will install batteries, an antenna and other hardware.
