An #Astrosphere is a giant bubble of hot gas that a star blows out into the space around it. It is created by stellar winds, which are strong, continuous streams of gas flowing away from the star. https://knowledgezone.co.in/kbits/6a4c9f013

What “astrosphere” means
WikipediaA stellar-wind bubble is a cavity light-years across filled with hot gas blown into the interstellar medium by the high-velocity stellar wind from a single massive star of type O or B. Weaker stellar winds also blow bubble structures, which are also called astrospheres. The heliosphere blown by the solar wind, within which all the major planets of the Solar System are embedded, is a small example of a stellar-wind bubble.

every network with a public tag surfaceFollow #astrosphere straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/astrosphere
