Today I learned a new rebuttal to the constant response from tech bros to me complaining about satellite pollution: WeLL JuSt PuT ALL yOuR tEleScOpEs iNtO SpAcE! While astronomers have way more ground-based research telescopes, greenhouse gas emissions from astronomy are dominated by the few space missions. I had no idea there was such a big discrepancy.
Thanks for the great/depressing/important paper @jknodlseder
