ATLAS releases 2025 beta open data for education and outreach

A major update for the 13 TeV ATLAS Education and Outreach Open Data

The ATLAS Collaboration has just launched a new release of open data designed to empower education, outreach and citizen science. Building on a commitment to open access, the new 2025 Open Data for Education and Outreach (beta) release offers a significant upgrade in usability, scale and technical support.

This release simplifies and expands on previous open data releases with a dedicated, open-source framework, now publicly available, alongside enhanced tools and documentation. It includes:

• Guided workbooks and code to help users analyse real LHC collision data
• Modules to build computing skills, perfect for students and independent learners
• Support for educators to create custom courses and projects using real LHC data

If you’ve used ATLAS Open Data before – this is also a big refresh. With increased statistical power and updated tools, you can pursue all-new physics analyses and revisit previous ones with enhanced precision.

So whether you’re a student, teacher, citizen scientist or just curious about the Universe – dive into ATLAS Open Data for Education. Explore real LHC collisions, develop valuable computing skills and uncover the properties of fundamental particles for yourself.

The data are all available now on the CERN Open Data Portal. You can also explore the documentation of the new release or visit the ATLAS Open Data Portal for more. We will be building on this beta release with additional data selections, analyses, and tools that will all be arriving soon!
