If you feel like making the trek out to the Lämpiö foyer (near Neptune) this evening, you can chat with me about clouds at L32! #EPSCDPS2025

Engaged in some light lunar eclipse spotting on the first night of #EPSCDPS2025 🔭

If nothing else being up at 5 will let you see planets

www.nasa.gov/missions/mar... Our JPL engineers continue to blow my mind with their talent. Squeezing every drop of science out of our wonderful rover that we can! (h/t to @dougellison.bsky.social for making my late night request to acquire this Navcam postcard a reality. The view was too good!)

The 12th annual international Gender Census 2025 is now open until at least 30th August 2025! survey.gendercensus.com It's for anyone whose gender (or lack thereof) isn't described by the M/F binary. It's short and easy, and results are useful in academia, business and self-advocacy.

Sometimes a group meeting can be seven grad students, three undergrads, a postdoc, and their advisor all working on Mariner 4 inspired art. (Original image: photojournal.jpl.nasa.gov/catalog/PIA2...)

Lunchtime companion

Eli saying "why is transgender uniquely an identity that cannot be spoken of historically" really sums up neatly why I love your trans history episodes so much!

They don't want you to know this, but this is actually what the ideal Mars mission looks like.

Solstice sunset, sped up 5x

Frost!!! ❄️ science.nasa.gov/blog/curiosi...

Now that it's been properly proofread and all, everyone welcome to the world my latest #PlanetaryScience paper where I take a sharp turn from atmospheric water vapour into the more murky world of martian methane... www.sciencedirect.com/science/arti...

New research from @transmartian.bsky.social hot off the presses! Using measurements of methane in the Canadian Arctic, Alex showed that variability in methane concentration is a better predictor than absolute concentration of how far away you are from a source: york-pvl.blogspot.com/2025/06/unra...

Please CSA, my creation demands a name

This Zenith Movie was taken on Sol 3046 (2021-03-02) at approximately 17:39 LTST and a solar longitude of 11.11°.

(1/) This one was part of an image sequence we use to measure the altitude of clouds over Gale by using the velocity of the clouds and the shadows they cast on the ground. It's been more difficult recently because our primary shadow target (Mount Sharp) has been hidden by nearby topography.

BREAKING: Pierre Poilievre successfully completes greatest election fumble in Canadian history

The campus is going pretty hard on this whole spring thing

This week, PhD student @conorwhayes.bsky.social talks about their experience collaborating with other scientists outside of our research group from across the world. Read more about how Science is a team sport here: york-pvl.blogspot.com/2025/04/the-...

Happy one year anniversary to me unintentionally recording myself having the most visceral and overwhelming reaction to anything I've ever experienced.

Happy one year anniversary to @conorwhayes.bsky.social and I experiencing a midly earth shattering cosmic event in Kingston Ontario

Aligned a couple of images from the #Kilauea webcam to show off changes following Episode 15.

Dust devil caught on sol 4487 by the Mars Curiosity Rover. The motion of some very thin clouds is also apparent.

Looking for something to do for the last morning of #LPSC2025? Why not pop in to the Earth Analogues session where at 8:55 you can learn how arctic methane plumes can inform future methane sampling on Mars.

It's #LPSC2025 poster day once again. Come see me at poster 92 this evening to talk about my efforts to quantify the effect of molecular recombination on water delivery rates to lunar PSRs.

If you need your cloud fix, you can head on over to my #LPSC2025 poster and hear about the newest addition to the Alex family of projects

Curiosity be all "I can see my house from here"

Really into this whole sun setting after 5 PM thing

Home* is where the award-winning tap water is. (*Toronto)

This sign really effectively captures the feeling of voting in this provincial election

Been a good week for snowflakes

Taking a moment to breathe and watch the pearly clouds go by (on Mars). www.nasa.gov/missions/mar...

NASA employees were sent this email verbatim today from our acting director.

Love it when Curiosity sends back images of wispy clouds in the martian sky... Sol 4423 image Credits: NASA/JPL-Caltech/S Atkinson

There is nothing like the arrival of the mid-month Queer as Fact episode to startle me into remembering the passage of time

Folks, a huge number of people at JPL have been affected by the LA wildfires, with many losing their homes. If you can, consider contributing to a fund that's been set up to help them: (Link looks sketch but site is legit) caltech.imodules.com/controls/ema...

Check out this blog post by Alex Innanen @transmartian.bsky.social on observations of noctilucent clouds by the Mars rover Curiosity science.nasa.gov/blog/sols-44... #Mars 🧪 #planetaryscience

These ones got a little press release a few years ago science.nasa.gov/resource/cur... #PlanetaryScience

It's important to take bad phone photos of the moon sometimes for your health

For martian cloud fans, some more (older) (less visually spectacular) clouds* ☁️ *research note contains no pictures of clouds, only graphs about them #PlanetaryScience

Solstice activities included baking a saffron cake to lure the sun back. It did still vanish at 16:40 this afternoon so we'll have to see if it indeed returns tomorrow...
