Dark Matter Day

The search for dark matter is a global pursuit to broaden our understanding of the universe. Explore this map to see where active and upcoming searches for dark matter are happening; you might even be surprised to find one near you! symmetrymagazine.org/dark-matter-da… #DarkMatterDay

Join the adventure! Storyteller David Telese and @CERN physicist Baptiste Ravina present a magical show for kids that unveils the mysteries of dark matter 🌌✨ #DarkMatterDay 🗓 November 8, 2025 ⏰ 2:30PM 📍 Physical Event Learn more: interactions.org/node/54898

This #DarkMatterDay, join Dr. Sebastian Trojanowski for a science talk on the search for dark matter — from astrophysics to particle cosmology. 🌌✨ 🗓 November 4, 2025 ⏰ 6:00PM 📍 Physical Event Learn more: interactions.org/node/54925

What happens when you mix Halloween with #darkmatterday? Physics pumpkins, of course! 🎃 🎃 Grab spooky science stencils from the ATLAS Experiment at @CERN, including a special Dark Matter design! 🔗 cern.ch/stencils

Who else is celebrating #DarkMatterDay? Euclid, our #DarkUniverse 🕵️ detective certainly is, though not taking the day off. With 1% of the its survey recently marked, there is plenty more to observe to unlock the secrets of dark matter and dark energy.

Happy Halloween and #DarkMatterDay! 🎃👻 On Oct. 31, we celebrate the hunt for the universe's missing matter. 🔎 Ordinary matter, like stars and planets, makes up just 4.9% of the universe's mass and energy. The rest is a spooky physics mystery: bit.ly/3sJ1Bhp

What if the first stars were powered not by fusion, but by dark matter? 🌌 On #DarkMatterDay, explore a new @PNASNews study from #NASmember Katherine Freese, whose team used @NASAWebb to identify possible supermassive dark stars. Read more: ow.ly/1FCA50XkU8I

Halloween is also #DarkMatterDay! 🎃🌌 Celebrate the invisible forces that shape our universe with @savagitsky, @ClaireLamman, and @sanjanacurtis as they reflect on how studying the origins, elements, and mysteries of the cosmos connects us all.💫 #scicomm #astronomy #cosmology

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.

Happy #DarkMatterDay! Every year around the 31st October, we celebrate the historic hunt for the unseen... 🔍🌌 See if there's an event near you: interactions.org/dark-matter-day

🌌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. snolab.ca/news/searching… @DarkMatterDay

WHAT IS DARK MATTER DAY? There’s more to the universe than stars, planets, asteroids, comets & space dust. In fact, there’s a lot more to the universe that we can’t yet explain. interactions.org/dark-matter-day #STEM #DarkMatterDay #SciChat #Halloween 🎃

／ ハロウィンだけじゃない🎃 10/31は #ダークマターデー #DarkMatterDay ＼ ダークマターにダークエネルギー...🌚 宇宙はダークなもので満ちている⁉️ Quantum Kate 第10話「ダークな物ばかり」 youtube.com/watch?v=O480Fh… KEKは、デンマークにある素粒子物理学の研究機関 CP3-Origins が制作した動画「Quantum Kate」の日本語吹き替え版を制作しました。2分程度でさくさく観られるので、ぜひご覧ください✨

Did you know most of our universe is made up of something unknown? While researchers have inferred the existence of dark matter, no one knows what it actually is. Here to explain more this #DarkMatterDay is Dr Shyam Balaji, @KingsNMES. kcl.ac.uk/dark-matter-day #ScienceAtKings

Happy #DarkMatterDay!

Explore the mysteries of dark matter at the Faculty of Science! Kids & adults can enjoy hands-on experiments and a telescope observation of the night sky. 🌌 #DarkMatterDay 🗓 Oct 31, 2025 ⏰ 5:30 PM 📍 In person More info 👉 interactions.org/node/54919

The Planetarium of Castelló is once again bringing the mystery of the Universe to life with special events celebrating Dark Matter Day in Castelló de la Plana! @PlanetariCs #DarkMatterDay 🗓 October 31, 2025 ⏰ 5:00PM 📍 Physical Event Learn more: interactions.org/node/54835
