Illustration of the separation of the SWCX foreground emission from the cosmic X-ray sky, for the Western Galactic hemisphere. The stripe patterns visible in the SWCX image result from temporal variations in foreground emission combined with eROSITA's scanning geometry. (Image credit: MPE) Astronomers have, for the first time, spotted the "breath of the solar system." The finding comes in the form of X-ray emissions generated when the electrically charged solar wind slams into both Earth's atmosphere and the bubble that surrounds our solar system, the heliosphere. This phenomenon, known as "solar wind charge exchange," was observed by the eROSITA space telescope, allowing a team of scientists to create a map of the sky in so-called "soft X-rays." This X-ray glow is radiated when the heavy ions of the solar wind , like carbon and oxygen, grab an electron from neutral atoms in either our outer atmosphere or the heliosphere.…
