Today! Earth Day talk by @a4e.org (Astronomers for Planet Earth). Zoom link: universiteitleiden.zoom.us/my/astroleo?...

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

Attending the @a4e.org 5th anniversary meeting and realising that I really should try and do more.

Astronomers for Planet Earth is an amazing organization of astronomers who put the climate crisis at the top of priorities for science far above colonizing Mars. Here is the poster for their upcoming conference celebration! #Astronomy #ClimateCrisis @a4e.org

Reminder! ⬇️

In just under two weeks, we will celebrate 🎉 five years of Astronomers for Planet Earth in an international, all-time-zone virtual meeting. Will you join us to discuss the role astronomy and astronomers can play in solving the climate crisis? See a4e.org/5th-annivers... for details and registration.

We couldn't agree more. Studying our amazing universe brings us to the conclusion that Earth is our only home, the home we must protect for generations to come.

Back in the 1980's, our staff at the Astronomical Society of the Pacific, an organization that would soon celebrate its 100th anniversary in 1989, created a series of fun bumper stickers. Here is one of my favorites. #astronomy #astroedu #humor #bumperstickers #sciencejokes #science

Happy solstice everyone!

Dear all! Come celebrate A4E's 5th Anniversary! Thursday, January 23, 2025, UTC 0800-1100 & UTC 1800-2100; Zoom + Spatial VR. Will you discuss with us where A4E can be in another 5 years? All info and registration at astronomersforplanet.earth/5th-annivers...

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.

5 years ago, I realised that my #academic travels were emitting way too much #greenhouse #gas #GHG (up to 20 t #CO2 / yr) and hence that my #professional activity was not #sustainable. I thus decided to completely ban air #travel (#plane) and travel mainly by #train within Europe. #Climate (1/2)

There is no Planet B @a4e.org

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:

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.
