Every time the shutter closes on @VRubinObs 3.2-gigapixel camera, 25 GB of raw pixels start a year-long journey: cleaned up, turned into alerts within a minute, reprocessed, and validated against 3,000+ requirements. Here’s what happens to each image 🔭 kipac.stanford.edu/news/what…

What Happens When the Camera Shutter Closes?

Each time the shutter closes on the world’s largest astronomical camera, 25 gigabytes of raw pixels begin a year-long journey. At the Rubin Observatory, images reach California in seconds, are...

Welcome to the dark site 🕸️ We have a whole new news collection web page for our dark matter content! Not quite 85% of all SLAC matters, but still plenty to explore: stanford.io/3VypOsw
A simulation of the formation of dark matter structures from the early universe until today. The detailed visualization of a cosmic web, showcasing filaments of dark matter interspersed with glowing galaxies. The image highlights the large-scale structure of the universe, with various bright spots representing galaxy clusters connected by wispy, thread-like structures.(Ralf Kaehler/SLAC)

🌌 Big news! KIPAC's Aaron Roodman is featured at #97 in @nytimes' "100 Scientists Weigh In" on science's biggest unanswered questions. Aaron leads the LSST camera program and studies dark energy with @VRubinObs. 👏 nytimes.com/2026/10/05/scien…

What Are the Biggest Questions in Science Today? 100 Scientists Weigh In.

We asked 100 scientists about unsolved problems in their fields. They sent back provocations — on the origins of life, the possibilities for human progress and much more.

A single weird particle just lit up the world's biggest dark matter detector, buried nearly a mile underground. 🕳️ Not a discovery yet (2.6σ) — but physicists can't explain it away. 🔗 science.org/content/article/… #DarkMatter #KIPAC

World’s biggest dark matter detector spots a single weird particle

It’s far too early to declare a discovery, physicists with the LZ detector say

Could this unexpected signal be our first detection of dark matter? The LUX-ZEPLIN experiment, world-leading dark matter detector, has observed a particle interaction that is the most compelling hint of dark matter reported by the experiment to date: stanford.io/4gvEi4D

KIPAC's Tina Cartaro just helped flip the switch on one of the world's most sensitive dark matter hunts. 🌌 Dark matter makes up 85% of everything in the universe — but no one has ever directly detected it. That's about to change. news.stanford.edu/stories/20…

Scientists hunt for dark matter deep underground

A SLAC-led experiment more than a mile beneath a Canadian mine has begun collecting early scientific data ahead of a full-sensitivity search next year.

We know dark matter exists from its gravity — we've just never caught it directly. Our own scientists are chasing that first catch. #KIPAC #DarkMatter #SLAC #Stanford

SuperCDMS SNOLAB, led by @SLAClab, just started collecting real data more than a mile underground in Canada. Its detectors are chilled colder than outer space itself — designed to catch the faint signal of a dark matter particle finally striking a crystal.
