I understand that, but if it’s a telescope they have to be “looking” at something in space, so how do they know what they’re “looking at” if it’s not aimed at something?

It’s not a study of neutrinos it’s a study of the source of neutrinos, just like an optical telescope is not a study of photons, but a study of the body that emitted (or reflected, as in the case of planets) those photons.

Interesting semantic argument. A telescope detects X (radio waves, photons, X-rays, gamma rays, etc.) from a source. This one detects neutrinos. Every telescope has an angle of view. You could consider this one to have a 360 degree angle of view, omnidirectional I guess.

In any case, this and its smaller predecessors are considered to be telescopes.
