SNOLAB is excited to be welcoming a new group of students for the Winter 2026 co-op term! These students are going to get some great hands-on experience working on a variety of projects ranging from data analysis on dark matter experiments to improving IT systems.

Congratulations to Roseann Runte, former president and CEO of the Canada Foundation for Innovation and vice-chancellor of Carleton University, on being appointed an Officer of the Order of Canada. www.gg.ca/en/appointme... #InnovationInCanada #WomenInLeadership #CanadianExcellence

Did you know SNOLAB provided valuable work experience to 44 students over 3 cohorts last year? The majority (72%) come from Ontario institutions. 64% of SNOLAB alumni begin their careers in Ontario. Read more in SNOLAB’s latest Annual Report here: www.snolab.ca/wp-content/u...

Did you know SNOLAB hosts more than 1,200 facility users and collaborators from 166 institutions across 26 countries? 24% of users are from Canadian institutions. Read more in SNOLAB’s latest Annual Report here: www.snolab.ca/wp-content/u...

SNOLAB continues to be a leader in underground science, training, outreach, and in the community. Read about it all in SNOLAB’s latest annual report - Innovation Lives at SNOLAB: Ontario’s training ground for scientists, technologists, and tradespeople. www.snolab.ca/wp-content/u...

The fifth and last image featured on our annual Holiday Card is a representative photograph of yeast colonies grown on a solid agar nutrient mix. Their growth was quantified by measuring their relative colony area (black spots). 🧵[1/3]

The fourth image on our annual Holiday Card features the SNO+ laserball, a tool used to help calibrate the SNO+ detector. The laserball is a special light diffuser connected to a fibre optic cable that sends light to the detector’s photomultiplier tubes. 🧵[1/2]

The third image on our annual Holiday Card highlights the PICO-500 pressure vessel, a component of a next-generation dark matter experiment. PICO-500 will use 250 litres of super-heated liquid contained within a specially manufactured quartz vessel. 🧵[1/2]

The 2nd image on our annual Holiday Card shows a qubit sample holder. Qubits are building blocks of quantum computers, much like transistors are for classical computers. Unlike classical bits that are either 0 or 1, qubits can exist in combos of both, using the rules of quantum mechanics. 🧵[1/2]

The first image on our annual Holiday Card is a bird's eye-view of the nested cryogenic cans in SuperCDMS, which house very sensitive dark matter detectors. These cans are cooled to temperatures just a few millikelvin above absolute zero, or –273 degrees Celsius. 🧵[1/2]

Happy holidays from the team at SNOLAB! Each year our holiday card features experiments at our facility. Throughout the week we will be diving into the components of this year’s card. ❄️ Stay tuned for some cool science.

SNOLAB research group manager Stephen Sekula dazzled Sudbury Rotarians with SNOLAB science at their meeting yesterday. His talk told the story of a dead star and how SNOLAB is contributing to the search for the next supernova. Thank you to the Rotary Club of Sudbury for supporting SNOLAB science!

Last week, the SNOLAB community came together to enjoy over a dozen talks from this term’s students. This event has students share their experience from the term to their peers and the broader SNOLAB community. To read more and see the winners, visit here: www.snolab.ca/news/student...

New breakthrough in detecting ‘ghost particles’ from the Sun at SNOLAB. The SNO+ experiment has recorded the first observation of carbon-neutrino interactions, findings that open new frontiers in nuclear and particle physics. #Physics #SNO+ www.snolab.ca/news/new-bre...

The search for dark matter is part of an effort to better understand our universe - and SNOLAB isn’t the only facility researching it. Check out this article and interactive map by @symmetrymagazine.org to find out more: www.symmetrymagazine.org/article/dark...

SNOLAB was thrilled to take part in the Sudbury Santa Claus Parade. Thank you to everyone who came out, to our social committee and the volunteers who made The Neutrino Express a reality, and to Johnny's Transportation Services for supporting our float. What an amazing community to be part of!

Today is the International Day of LGBTQ+ People in STEM. This day is used to bring awareness to the barriers that the LGBTQIA+ community still faces today but is also used as an opportunity to celebrate and highlight the important work that is contributed by removing these barriers in STEM. 🧵 [1/2]

❄️ Having a chill start to the week at SNOLAB! SNOLAB uses a special technique to measure trace amounts of radon in infrastructure and experiments in the underground laboratory. This method, a radon assay, requires cryogenic temperatures to make it work. 📸 Photo by Gerry Kingsley
