Chandra telescope captures first image of a protective bubble around a Sun-like star

Star system: HD 61005 | Distance from the Sun: 119 light years

Astronomers using the Chandra X-ray Observatory have achieved a scientific first by resolving the 'astrosphere'—a protective bubble created by stellar winds—around a young, Sun-like star named HD 61005. Located about 119 light-years away, this star is a much more active version of our own Sun as it appeared in its youth.

The study revealed a glowing halo of X-rays extending 220 astronomical units wide, caused by the star's wind crashing into the surrounding interstellar gas. This discovery provides a rare glimpse into how our own solar system might have looked billions of years ago when the young Sun was navigating through much denser regions of space.
