Astronomers for Planet Earth

Astronomy students, educators, & scientists addressing the climate crisis from the astronomical perspective. Join the conversation with #Astro4Earth!

What a pleasure to attend the @a4e.org 5 Year Anniversary meeting! Online, of course. I particularly love the accountability tools and action items they are developing for astronomers (but really any researchers). Tl/dr: Be honest about your footprint, know how you can reduce it, and just do it. 1/n

Moderators are an important part of the Astronomy feeds community who help to keep it healthy! 🔭 We're nearly ready to appoint a new batch of mods, but would really like more applications from women & gender minorities. You do NOT need past experience to apply!

What should our next biggest telescope be? Is not building a new one an option? Funds could be used to keep existing facilities alive (including upgrades) for a bit longer.

At @a4e.org the idea is being discussed to propose building … nothing. :) But use existing facilities better and for a longer time (incl. upgrades / new instruments). Perhaps more R&D is also required for the next really big thing (a large heterodyne optical interferometer using laser frq combs?)

How much did astronomers actually travel in terms of distance in 2019 in total? More than 300 times to the moon and back! Or, to put it in astronomical units: more than 1.5 AU! doi.org/10.1093/pnas... A🧵summarizing our paper, written together with members of Astronomers for Planet Earth:

The authors are, in the order of the author list: Andrea Gokus, Knud Jahnke, Paul M. Woods, Vanessa A. Moss, Volker Ossenkopf-Okada, Elena Sacchi, Adam R. H. Stevens, Leonard Burtscher, Cenk Kayhan, Hannah Dalgleish, Victoria Grinberg, Travis Rector, Jan Rybizki, and Jacob White.

Hello world, We're happy to finally join the BlueSky community, too. This account will be used to repost articles and discussions concerning sustainability in astronomy (e.g. carbon footprint analysis of astronomical research projects) as well as climate communication projects with an astro angle.
