This Hubble image shows NGC 1672, a barred spiral galaxy some 49 million light-years away in the constellation of Dorado. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Six filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This artist impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of km per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. The inset shows what is happening at galaxy’s heart. A supermassive black hole draws in gas from its surroundings, which forms a hot, brightly lit accretion disk (orange). The cause of the winds (white) is magnetic fields within the disk, which fling particles out in all directions at incredibly high speeds. These winds effectively block out X-rays (blue) which are sent out by the extremely hot plasma surrounding the black hole, called the corona. Zak et al. caught Markarian 817 blasting out ultra-fast winds using ESA’s X-ray telescope XMM-Newton. Lasting for around a year, the winds will have significantly affected star formation in the galaxy. The fact that the black hole at the center of the galaxy was showing rather average activity levels before producing the winds suggests that ultra-fast black hole winds are much more common than previously thought. In other words, black holes and their host galaxies strongly affect each other’s evolution. Image credit: ESA / CC BY-SA 3.0 IGO.

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.
