<span style="font-size:11pt; background-color:rgb(255,255,255); vertical-align:baseline">Stars radiate energy by releasing photons from the stellar surface and neutrinos from the stellar interior. In the stellar interior, weak reactions produce electron neutrinos
by thermal processes, electron and positron captures on nuclei, and nuclear decays. Neutrinos interact feebly with baryonic matter, escaping from the star unhindered in circumstances where photons are trapped. Neutrino astronomy has been limited, so far, to
the Sun, supernova 1987A, and blazar TXS 0506+056. However, the Super-Kamiokande with Gadolinium, Jiangmen Underground Neutrino Observatory, and XENON experiments usher in a new generation of multi-purpose neutrino detectors designed to open new avenues for
potentially observing currently undetected neutrinos. In this talk we'll explore recent results on stellar neutrinos that provide new targets for current, forthcoming, and future generations of neutrino detectors, new estimates of the stellar neutrino background
signal, and new opportunities for nuclear reaction data that can make sizable differences in stellar evolution.
