A new set of predictions for the so-called "blaze star," T Corona Borealis suggests the star might go nova on either March 27, November 10, or June 25, 2026. However, other astronomers are skeptical about these predictions, which are based on an implied pattern in the explosive system's orbital configuration,
"T Corona Borealis [T CrB] is a unique object that has fascinated amateur and professional astronomers for more than a century," Léa Planquart of the Institut d'Astronomie et d’Astrophysique at the Université Libre de Bruxelles in Belgium, told Space.com.
T CrB is a symbiotic binary, a vampire system in which a white dwarf is siphoning material from a red giant star. A white dwarf is the dense, compact core remnant of a once sun-like star, packing a mass equivalent to that of a star into a volume about the size of Earth. A red giant represents an earlier stage in a star's evolution, when a sun-like star starts to run out of its hydrogen fuel supply and begins to swell. 0 reply

Scientists have confirmed the existence of four small, rocky planets orbiting Barnard's Star — the second closest star system to Earth — using a specialized instrument on the mighty Gemini North telescope in Hawaii. Just six light-years away from us, all the worlds are too hot to support life as we know it.
This find is particularly exciting, explained Ritvik Basant, who is a Ph.D. student at the University of Chicago and an author on a paper about the new discovery. This is because, he said, Barnard's Star is essentially our cosmic neighbor, yet we don't know very much about it.
There have been many claims of exoplanets orbiting Barnard's Star over the years, dating all the way back to the 1960s. Barnard's Star is a red dwarf, also known as an M-dwarf, and is noticeable for having the fastest proper motion, in reference to its motion visible in the night sky, of any star so far discovered. 0 reply
