eROSITA disentangles the solar system's X-ray glow from deep-space signals

Max Planck Institute for Extraterrestrial Physics scientists have been able to disentangle the X-ray glow originating in our solar system from similar emission reaching us from deep space, using data from the SRG/eROSITA space telescope. Four sky maps obtained between 2019 and 2021 from a vantage point approximately 1.5 million km from Earth—approximately four times the moon's distance—enabled the extraction of solar-wind charge exchange (SWCX) emission. The research is published in the journal Science.
