Neutrino detector finds new type of “ghost particle” from the Sun

Borexino, a huge underground particle detector in Italy, has picked up a never-before-seen type of neutrino coming from the Sun. These neutrinos confirm a 90-year-old hypothesis and complete our picture of the fusion cycle of the Sun and other stars.Co… Continue reading Neutrino detector finds new type of “ghost particle” from the Sun

NASA and NOAA have confirmed that the Sun has entered a new solar cycle, with activity beginning to ramp back up from its minimum in December 2019. This next cycle is forecast to be rather quiet, continuing a long-term trend of reduced activity from ou… Continue reading Sun’s activity flares up as NASA confirms start of new solar cycle

NASA selects concepts for future missions to examine space environment

NASA has announced the selection of five Medium Class Explorer concept missions that could one day revolutionize our understanding of the space environment. The proposals include efforts to collect imagery of the Sun’s poles, and explore how the solar … Continue reading NASA selects concepts for future missions to examine space environment

Sun’s long-lost twin could have captured Planet Nine

While the Sun is very clearly a solo act nowadays, some astronomers theorize that it once had a binary companion star. Now, Harvard scientists have added weight to the idea by showing that an ancient binary solar system explains the strange structure o… Continue reading Sun’s long-lost twin could have captured Planet Nine
