Currently attending #AAS235 Special Session “Challenges to Astronomy from Satellites”. As someone studying variable and transient phenomena, I care deeply about this issue.
Current talk is from Patricia Cooper (SpaceX) about Starlink.
Cooper: SpaceX is aiming to reach a threshold number of satellites to provide continuous broadband service. Initial estimate of ~1400 satellites over 24 launches to provide “decent” coverage.
Yesterday was an incredible day for publications in my research groups. One big surprise to me was that my own first, first-authored paper made its way onto arxiv last night! I’m so excited to share this work with all of you. #AAS235 arxiv.org/pdf/2001.01338…
One of the most well known potentially habitable exoplanets, TRAPPIST-1e, has been the subject of transit modeling simulations with JWST for the last few years. Thanks to the findings of these works, it was determined that only CO2 may be detected if the planet is “Earth-like”. 
Because of this reality, I wanted to know what it would take for an observatory to expand their detections beyond CO2 to include signatures of habitability/life such as CH4, H2O, O2, O3, and N2.
First #AAS235 press conference "Galaxies & Their Black Holes" streaming in 15 minutes at aas.org/press/AAS-pres…, topics at aas.org/meetings/aas23…
The first presentation at the first #AAS235 press conference was about the paper arxiv.org/abs/1909.04670 on "A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High Resolution Radio Observations".
The Molecular Gas in the NGC 6240 Merging Galaxy System at the Highest Spatial Resolution - dropbox.com/sh/vd7raj123rs… and also arxiv.org/abs/1910.12967 and davidaustria.tumblr.com/post/119674013… and public.nrao.edu/news/the-turbu… - was the topic of the second presentation of the first #AAS235 presser.
