I will share more information soon regarding the site visit to #SURF, a sister underground laboratory to #SNOLAB. I want to share now that the "Deep Talk" lecture I delivered last night at the SURF Visitor Centre was an incredible experience. I was especially excited to be able to personally interact with over a dozen audience members. This included an awesome small-group Q&A session after the formal event.

Watch the lecture online:

Exciting news from the depths of the Mediterranean Sea! A submerged neutrino detector has identified the most energetic "ghost particle" ever observed, with energy levels 30 times higher than previous records. This discovery could shed light on high-energy processes beyond our galaxy.

The neutrino left its trail while the observatory, #ARCA, anchored deep in the Mediterranean Sea, was still under construction.

“We’ve never seen a #neutrino this energetic, & we have been looking for them for a few decades now,” Wissel said. “We’re trying to understand what the #universe is capable of & how it does it — & this one neutrino is exciting.”

In this case, one possibility is that a very energetic cosmic ray interacted w/the cosmic microwave background [leftover radiation from the #BigBang] & produced this #neutrino. Another is that the particle was created when a “#blazar,” a #galaxy w/a #SupermassiveBlackHole at its center, gobbled up stars. But the debate is only beginning.

Stephanie Wissel, a PennState neutrino physicist, not involved in the research, called it a “knock your socks off” observation & a remarkable stroke of luck.

“It’s incredible, right?” #neutrino physicist Paschal Coyle, a member of the #KM3Net team that did the research, said. “There are these objects in the #universe that can accelerate particles to such extreme energies. How that’s done, we don’t completely understand yet. So every piece of information that gives us a clue of the processes involved in achieving such high #energy — this is one of the main goals of #astronomy.”

Just as astronomers use telescopes that observe the light from stars to explore & explain the universe, scientists have set up massive telescopes deep in water & ice to measure #neutrino. These cosmic messengers can travel undisturbed over vast distances, carrying information about mysterious high-#energy events that generate them.

An international team of scientists announced Wed the detection of an extraordinary, elusive #neutrino — a tiny, subatomic particle that flitted at close to the speed of light toward an undersea detector off the coast of Sicily carrying about 30k times the #energy generated by the largest particle accelerator on #earth.

The observation, unveiled in the journal #Nature, revealed the highest-energy neutrino ever detected.

Day 2 of 6: This week, I'll be sharing bits of my creative process in making the comic book stories of six incredible AAAS SciAll IF/THEN Ambassadors! Here's material from the comic about astrophysicist and Assistant Professor at Darmuth College Dr. Burçin Mutlu-Pakdil. I loved working on this project! Find all the comics sciall.org/projects/ ! A new one tomorrow! #comics #science #fermilab #neutrino #physicist #STEM #cartoon #AAAS #IfThen #WomenSTEM #drawing #art

Sketched page of the comic about Dr. Burçin Mutlu-Pakdil. We can see her in her office, her arms crossed, and happily introducing herself.
