Hi! Nuclear + astrophysics student here. I feel like I need to be specific about Ice Cube. Normally being pedantic makes things boring but in this case it actually makes them way more interesting. Hank says that the neutrinos generate flashes of light as they move through the ice which is *correct* but the specific way they do that is actually really cool. Neutrinos, because they weigh almost nothing, travel very very close to the speed of light. When a neutrino barrels through a solid substance like ice, it can sometimes create particles like electrons. These particles inherit the momentum of their parent neutrino and slam through the ice at speeds very close to c, faster than photons move through the ice. This produces a cone of light behind them called Cherenkov radiation. It's the same effect as how if you go faster than the speed of sound in air you get a sonic boom behind you. Cherenkov radiation is also seen in some nuclear reactors - it makes reactors kept underwater glow blue because electrons overtake light in the water - where light moves more sluggishly - as they fly out of the reactor. It's even more pronounced in ice because light moves quite slowly in it. So tl;dr the 'flashes of light' Hank mentions are tiny shocks of photons exploding through the ice - sonic booms of light - as particles created by the neutrinos hitting ice molecules go faster than the speed of light in the ice. And it's the same light that nuclear reactors make.

We use that information to get the direction each neutrino came from originally and reconstruct a map across the sky.

In many of them, the products of their interactions can move along approximate lines that we can extrapolate backwards to an approximate original direction from before it entered the detector. The Earth does actually block neutrinos of a high enough energy, and we see that in the data that is collected. We can reconstruct things much better if they came from the south sky, but enough make it through the Earth that it isn't too large of an effect. Additionally, because of the way neutrinos interact with matter, the Earth does somewhat change the kinds of neutrinos we see.

Thanx for talking about Ice Cube. I was a member of the team that deployed it, and went down to the South Pole 3 times. Specifically I worked on the surface array portion called Ice Top that primarily studies cosmic ray air showers. You have the mechanism on how Ice Cube works slightly wrong, it's much cooler than you describe. When a Neutrino hits an atomic nucleus another type of particle called a muon pops out of the collision. This muon is traveling faster than the speed of light in ice. This creates something analogous to a boat's wake, but in blue light, called Cherenkov radiation. This "wake" of blue light is cone shaped, and the sensors in Ice Cube can see this light and create a time stamped signal. Because the sensors are in a 3D grid, the computers collecting the signals can reconstruct the propagation of the cone of blue light showing how the muon moved through the array. (Sort of like seeing the movement of a speed boat over a lake from an airplane by the shape of the boat's wake in the water.) Knowing the movement of the muon through the array is important because the muon travels along the exact same vector that the Neutrino was traveling, so reversing the movement of the muon will point to where in the universe the Neutrino came from. Most of the "interesting" neutrinos for Ice Cube are traveling upwards through the array because the bulk of the Earth blocks most of the lower energy neutrinos that are probably from the sun or nuclear radiation here on/in the Earth. So, if you count the filter on your telescope as part of your telescope, you could consider Ice Cube to be as big as the Earth because it uses the Earth as a passive filter. Ice Top also provides some active filter functionality. Fun fact. There is a layer of dust that runs through the array. As I recall, the dust layer was from some volcanic event elsewhere on the earth, and the dust was trapped in the ice as it fell out of the atmosphere. I think the collaboration knows which event it was based on the estimated age of the ice, but I don't remember that detail. On a couple of the holes extra instruments were attached to the drilling stack to study the dust layer while the hole was drilled.

It never ceases to surprise me how incredibly good you are at describing why science is so interesting. Just such a perfect mix of respecting your audience's intelligence and interest, your own enthusiasm, and humor in your delivery.

The way you described the challenges and progress in observing neutrinos BEFORE showing the image made the image immensely rewarding. A lot of other science educators would start with the image and explain the challenges it took to get there, but if you start with the fact that they did a thing before explaining the challenges than you just take it as a given that the challenges weren't insurmountable.

It is always refreshing to watch Hank's enthusiasm for science. You, sir, are a freaking legend!

Firstly; on a positive note: I love the energy with which Hank talks about these things. But, the negative note; I almost couldn't help reflexively saying " --and it won't be for long if we don't fix our nonsense" after he said "Antarctica doesn't have to be there!"

Three distinct sources which we can detect (gravitational waves, photons, neutrinos), three cosmic backgrounds/maps we can compare against one another. It seems really important for putting our theories to the test, agreement between all three is a strong confirmation of the accuracy of our models and any diverges from expectation will be really telling. So excited to see where it all goes!

Antarctica is a harsh continet.
