A massive thank you to the folks from the STFC & Boulby Underground Laboratory for showing me around for #DarkMatterDay!

We went 1km underground & I spoke with people who do this every day to better understand how our universe works. It was such a unique experience & I can't wait to show you more!!

Today isn't just #Halloween🎃, it's also #DarkMatterDay!

Dark matter interacts via gravity, so while we can’t see it directly, we know it’s there.

NSF–DOE Rubin Observatory's 10-year survey will measure distortions in billions of galaxies, revealing where dark matter is hiding.🔭🧪

Please bear with us as we take a short break from mapping the Universe to turn our attention to pumpkin carving…

🌌Dark matter is a huge cosmic mystery, and much of the research underway at SNOLAB is focused on it.

This #DarkMatterDay read about the international efforts that are in progress at Canada’s deep underground science lab.

Today is #DarkMatterDay, and you know what's ironic about that?

The day itself is perfectly named as a day acknowledging dark matter, (although events involving this often take place near, but not on, that date, which is another irony altogether!), but "dark matter" is not.

What if the first stars were powered not by fusion, but by dark matter? 🌌 On #DarkMatterDay, explore a new @PNAS.org study from #NASmember Katherine Freese, whose team used NASA's James Webb Space Telescope to identify possible supermassive dark stars. Read more: www.pnas.org/doi/10.1073/...

Did you know? When scientists began brainstorming @vrubinobs.bsky.social 3 decades ago, they had the title Dark Matter Telescope in mind? With its wide field of view and sensitivity to the faintest objects, Rubin will reveal how dark matter and dark energy shape the universe. 🔭 #darkmatterday.

This #DarkMatterDay we give a shoutout to the #DarkUniverse detective 🕵️, our Euclid mission.

Euclid is hard at work, creating a great cosmic atlas to uncover the secrets of #DarkMatter & #DarkEnergy. 

Below you can zoom into the first page of this atlas.

👻 Happy Dark Matter Day! Dark matter makes up 85% of our universe yet remains one of the biggest scientific mysteries to this day. We’re working to uncover what shapes our cosmos because - everyone loves a mystery!

The @sciencecentres.bsky.social Space Community Calls have been such a joy to attend. It was a proper treat to spend my lunch break hearing from @astroroyalscot.bsky.social talk all things dark matter on #DarkMatterDay today.

Apparently today is #DarkMatterDay. Once upon a time, I got a PhD looking for the stuff. Apparently, they just give those things out even if you don’t find anything.
