Star system

A binary star supernova is a spectacular phenomenon where one of the stars in the system eventually collapses with an almost unimaginable explosion. Scientists at the University of California at Berkeley recently discovered a type of supernova that, fueled by helium instead of the usual carbon, is only about a tenth as bright as a normal supernova. A more frightening discovery is of a binary system in our own galaxy, only about 3,260 light years away, that had regular nova explosions every…

"Shortly before his disappearance, the famous philosopher, explorer, engineer, and machinist Calvo Galvan, left behind several pieces of nonsensical writings, insane scribblings, and incomplete schematics; known collectively as Galvan's Code. Among these was a map of the Heavens, or rather, a map of the nearby celestial bodies and stars. During Galvan's time of the 1100s, astronomic studies were still in a catch-up phase, as the general understanding of universe and cosmos had yet to surpass…

This weekend's "helical rising of Sirius" is a good way to learn about the brightest star in the night sky.

(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive neutron star in orbit with a companion white dwarf star puts competing theories of gravity to a test more stringent than any available before.
