The flare star Wolf 359 is another near neighbor (2.39 ± 0.01 parsecs). This star, also known as Gliese 406 and CN Leo, is a red dwarf of spectral class M6.5 that emits X-rays. [12] It is a UV Ceti flare star, [13] and has a relatively high flare rate. Artist's interpretation of Wolf 359
A modern LUU-2B flare at 1,000 feet altitude illuminates the ground at 5 lux in a radius of 1500 feet. Burn time is 4–5 minutes. The flare is 36 inches long, 4.9 inches in diameter, and weighs about 30 pounds. A similar design called LUU-19B can provide covert illumination in the near-infrared (IR) spectrum with virtually no visual signature.
Its giant flare was detected by the European Space Agency's Integral space observatory on Nov. 15, 2023, in M82, a galaxy boasting a star formation rate much higher than the Milky Way's - called a ...
A mysterious light has been blinking in space every 21 minutes for 35 years–and scientists have no idea what it is. What could it be?

A "zombie star" could possibly rise from the dead on Halloween night, according to space experts. T Coronae Borealis, also known as the "Blaze Star," is expected to explode violently in the near ...
Scutum Star Cloud with open cluster Messier 11 at lower left. Technically not star clusters, star clouds are large groups of many stars within a galaxy, spread over very many light-years of space. Often they contain star clusters within them. The stars appear closely packed, but are not usually part of any structure. [17]
