IXPE Provides a Fresh Look at Supernova RCW 86.

NASA's IXPE observed the supernova RCW 86 and released a composite image on March 24, 2026 that combines IXPE data with legacy X-ray observations from Chandra and XMM-Newton.

NASA's Imaging X-ray Polarimetry Explorer (IXPE) has taken a new observation of the supernova RCW 86, and a composite image was released on March 24, 2026. The image brings IXPE data together with earlier X-ray observations from other telescopes. It displays different X-ray energies and includes an optical starfield for context. This composite aims to add to the dataset available for study of the remnant. Image details: - Observation date: composite image released March 24, 2026. - Instruments combined: IXPE data overlaid with legacy X-ray observations from NASA's Chandra and ESA's XMM-Newton. - Color mapping: yellow represents low-energy X-rays and blue shows high-energy X-rays detected by Chandra and XMM-Newton. - Optical background: the starfield in the image comes from the NSF's NOIRLab. - Purpose: the observation helps fill in a fuller picture of what other telescopes have seen. Summary: The addition of IXPE's X-ray data complements existing X-ray and optical views of RCW 86 and contributes to a more complete observational record of the supernova remnant. Undetermined at this time.
