Bright New Satellites Join a Crowded Sky — Here’s How You Can Help
The imminent launch of a BlueWalker satellite, with a giant phased array antenna, portends a brightening night sky. Amateur astronomers can help record these changes with the goal of mitigating them.
Did Astronomers See a Distant, Dying Star? Or an Earth-bound Satellite?
What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common.

How can I spot satellite triads?
While binocular observing from Northern California on August 19, 2004, at 6:33 Universal Time, I picked up a trio of satellites moving from the northwest to overhead and passing through Cygnus. I’m sure they were satellites, as all three turned reddish at the same time before disappearing into Earth’s shadow.…
