noun, plural e·lec·tron-neu·tri·nos. Physics.
a type of neutrino that obeys a conservation law together with the electron, with the total number of electrons and electron-neutrinos minus the total number of their antiparticles remaining constant.
Beware the email rumor about “Betelgeuse.” What does “Betelgeuse” mean, anyhow?Betelgeuse has been in the news again recently. No, not the creepy character played by Michael Keaton in the 1988 Tim Burton movie Beetlejuice . We’re talking about the red supergiant star in the constellation Orion, that Betelgeuse.

There will be two bright, sun-like …
If you see an odd glow in the sky tonight, here’s what it’s called and its causeYou’ve heard of the northern lights? The next few days you may be able to see lights even if you aren’t that far north. The sun erupted on Sunday, spewing plasma, “a highly ionized gas containing an approximately equal number of positive ions and electrons” right in our direction. There’s no reason to freak out; solar storms are relatively common, and the most significant impact they have on …
