This Hubble image shows the spiral galaxy NGC 4651. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) instrument. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Reynolds et al used Chandra to look for extraordinarily low-mass axion-like particles in the Perseus galaxy cluster, a group of galaxies located 240 million light-years away from Earth. The observation lasting over five days showed no evidence for certain axion-like particles, which some theorists think can explain dark matter. The lack of detection in these Chandra observations helps rule out some versions of string theory, a set of models intended to tie together all known forces, interactions, and particles.

The structure of our Milky Way Galaxy with its warped Galactic disk, where the majority of its hundreds of billions of stars reside. Data from ESA’s Gaia spacecraft recently proved that the disk’s warp is precessing, essentially moving around similarly to a wobbling spinning top. The speed of the warp’s rotation is so high that it must have been caused by a rather powerful event, astronomers believe, perhaps an ongoing collision with another, smaller, galaxy which sends ripples through the disk like a rock thrown into water.

Evidence for the biggest black hole eruption seen in the Universe comes from a combination of X-ray data from Chandra and XMM-Newton, and the Murchison Widefield Array and Giant Metrewave Telescope, as shown here. The eruption is generated by a black hole located in the central galaxy of the Ophiuchus galaxy cluster, which has blasted out jets and carved a large cavity in the surrounding hot gas.
