IXPE and Chandra images have been combined to show X-ray data of the area around Sagittarius A. The lower panel combines IXPE data, in orange, with Chandra data in blue. The upper panel depicts a much wider field-of-view of the center of the Milky Way. The thin white lines layered onto the top panel frame the highlighted area, and indicate that the perspective in the bottom panel has been rotated approximately 45 degrees to the right. The combination of IXPE and Chandra data helped the astronomers determine that the X-ray light identified in the molecular clouds originated from Sagittarius A* during an outburst approximately 200 years ago.

This Hubble image shows NGC 7292, an irregular galaxy some 44 million light-years away in the constellation of Pegasus. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum Hubble’s Advanced Camera for Surveys (ACS). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
