Jewels and Junk in the Sky

Last night the full Cold Moon was big and bright as Jupiter rose in the clear sky over Pittsburgh. These two jewels were visible even among city lights, though they are much more beautiful in the photo from Sweden at top.

In March 2025 Nate Luebbe (@nateinthewild) was north of the Arctic Circle at Vestvågøy island, Norway when he witnessed snowfall with a rainbow (“snowbow”) and the Northern Lights. So many jewels all at once!

Sometimes a satellite photobombs the natural jewels. The satellite here was not too intrusive on the Moon and Venus.

But satellites can quickly become space junk when they outlive their useful lives or accidentally fall out of orbit. The falconcam at Cromer Church in Cromer, Norwich, UK captured an amazing blaze of space junk upon reentry in February 2025. Wait for 10 seconds for the space junk to appear!

The AMC-21 satellite will become space junk some day. Launched in 2008, it uses the C band to transmit broadcast television. It was expected to last 15 years — until 2023 — but it’s still running. SES-21 was launched in 2022 to take over AMC-21’s job.

Both satellites are in geocentric orbits, parked over the equator at different longitudes. AMC-21 at 125° West, SES-21 at 131° West.

When no satellite dishes are left pointing to AMC-21 it will become actual space junk and fall out of the sky.
