The astrophotographer I worked with earlier this month, Jeanine Holowatuik instagram.com/jeanine.holowatu… northernescapephotography.com/… sent me some horrifying (Halloween-levels of scary) time lapse movies she took of Comet Lemmon.

Why horrifying? Starlink.

I wrote a paper ui.adsabs.harvard.edu/abs/2022… a few years ago with Aaron Boley and @hannorein and our horrifying predictions for light pollution from satellites are matching up perfectly, Lemmon was low in the northwest for this video: mediaspace.uregina.ca/media/La…

I'd even argue we were a bit too conservative/optimistic in our assumptions of satellite brightnesses. I've never wanted to be wrong in a scientific paper before, but I sure wanted to be wrong about that one.

Shit.

Visibility Predictions for Near-future Satellite Megaconstellations: Latitudes near 50° Will Experience the Worst Light Pollution

Megaconstellations of thousands to tens of thousands of artificial satellites (satcons) are rapidly being developed and launched.

I suppose it is about the way in which you are wrong. It's one thing to be wrong because you got the facts wrong, or made unsubstantiated or incorrect extrapolations. It's quite another to be wrong because you sounded the alarm and changes were made so that the predicted outcome did not happen.

The worst is being right about an undesireable outcome because people just shrug and go "it's just one more" tens of thousands of times.

This looks almost exactly like our simulations from 2022:

If anyone wants to play with the simulations themselves, you can download our free iOS app "Mega Constellations" apps.apple.com/us/app/mega-con…. Although by now you might also just step outside and look up 😢

‎A mega-constellation is a collection of man-made satellites orbiting the earth. They operating together to provide internet and other communication services.

Pleez pardon me for saying it, Prof Lawler, but Musk is bahaving like an enemy to all life on planet earth.
Can we end his bullshit about going to Mars and just send him straight to Uranus?
