Astronomers Spot First Alien Astrosphere Around a Sun-Like Star
Astronomers using the Chandra X-ray Observatory have detected the first astrosphere—an outer wind-driven bubble—around HD 61005, a young sun-like star about 117 light-years away nicknamed the 'Moth.' The feature results from the star’s powerful stellar wind colliding with interstellar material and, captured in a multi-wavelength image, offers a glimpse of what our solar system’s early heliosphere may have looked like.
