- Neutrino (Wikipedia)
A neutrino (/njuːˈtriːnoʊ/ new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles (excluding massless particles). The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the electromagnetic interaction or the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected.
- Beta Cephei (Wikipedia)
Beta Cephei is a triple star system in the northern constellation of Cepheus. Its name is a Bayer designation that is Latinized from β Cephei, and abbreviated Beta Cep or β Cep. This system is a visible to the naked eye as a point of light with a combined apparent visual magnitude that ranges from 3.16 to 3.27, making it a third magnitude star. Based on parallax measurements obtained during the Hipparcos mission, it is approximately 690 light-years distant from the Sun. It is the prototype of the Beta Cephei variable stars.
