#exo3 Glad Dr. Günther highlighted the link between flares and the habitability of M dwarf planets! Flares can be sneaky. The widely acclaimed "boring" M dwarf GJ 887 looks flare-less in TESS data, but not so in the far ultraviolet!

The point, put explicitly: those of us who are white need to think harder about racism. Just because acts of overt racism are absent in a space does not mean the structure of racism is absent. Not joining in the effort to destroy this structure is tantamount to supporting it.

It's so nice to live a life free of #racism. My residence (#Tempe), my career (#astronomy), and especially my hobbies (#climbing) – not an ounce of hate in any! Curious, isn't it, that they're all almost entirely white?

@SESEASU Team Dynamos' annual retreat at @LowellObs, outdoors and social distancing - research intensive *and* therapeutic. It was great to see the team in 3D, again! Including @parkaroni, @joe_llama, @try2121.

One last #SPUV abstract: Brown et al. found Joule heating is influencing Saturn's outer atmosphere. I wonder, could Joule heating also play a role exoplanet atmospheric escape? For details on the rescheduled #SPUV, go to https://t.co/4CFNBsCxOP

A reminder from Moore & Cowan a la #SPUV that the lower boundary condition to a planetary atmosphere is not as simple as we scientists often like to make it. In short: rocks "breathe."

[Parke Loyd @parkaroni]

Another #SPUV highlight: Fleury et al. are making hot giant planet atmospheres in the lab!

[Parke Loyd @parkaroni]

Another #SPUV highlight: This question has been on my find for a while. Teal et al. have been testing what uncertainties in stellar UV spectra mean for photochemical models of planetary atmospheres. Can we fudge the UV or not? I hope to find out at the rescheduled SPUV 2021!

Next HAZMAT paper! Predicting the evolution of the unobservable extreme-UV radiation from early M stars, which drives planetary atmospheric escape and directly impacts a planet's potential for habitability, by Peacock et al. https://t.co/CW2aytQZvg

#SPUV might be delayed, but COVID can't stop us from tweeting some exciting SPUV science. SPUV would have (and will!) bring solar system and "exo system" scientists together. A solar system example: we can use UV light to detect surface carbon on Mercury, say Vilas et al.

@evgenya @mmacgreg Related: Though the flares on Prox Cen are intense, microorganisms from Earth could probably survive there! I wonder how UVC doses implied by new HST observations will compare to values used in microbiology lab experiments https://t.co/auGAEXjnVv

I'm going to pick out my five favorite abstracts and post one per day this week!

[evgenya shkolnik @evgenya]

Dear UV Enthusiasts, Today would have been the first day of the "Stars and Planets in the Ultraviolet" symposium @ASU, but we postponed to May 3-5, 2021. However, we posted the submitted abstracts we would have heard about this week here: #SPUV
ENJOY!
