NASA Telescope Spots a Young Sun-Like Star Inflating Its Astrosphere

This composite infrared and optical image shows the young Sun-like star HD 61005, about 120 light-years away. The zoomed-in image is made of x-ray observations from Chandra and Infrared observations from the Hubble. It shows how the young star is blowing "bubbles," or inflating its astrosphere.

Chandra's X-ray Space Telescope, with some help from the Hubble, spotted a young Sun-like star about 120 light-years away with a powerful stellar wind. It's carving out its astrosphere, a bubble of relatively hot gas that's pushing into the surrounding, much cooler, interstellar medium. This is the same process our Sun went through 5 billion years ago when it created the heliosphere.
