Astronomers have uncovered an extraordinary cosmic phenomenon deep in space. Using the Hubble Space Telescope, scientists observed an aging red giant star ejecting massive spheres of superheated plasma into the surrounding void. These are not ordinary flares — researchers describe them as gigantic “cannonballs” being hurled outward at extreme speeds. Each one is enormous, measuring roughly twice the size of Mars and burning at temperatures nearly double that of the Sun’s surface.
The star responsible is in a late, unstable phase of its life, swollen and volatile, which may explain these violent outbursts. As it sheds material, it offers scientists a rare glimpse into how dying stars behave before their final transformation. Discoveries like this help reveal how stars recycle matter back into the universe, shaping future generations of cosmic systems.
