The main panel of this image shows a wide-field view of NGC 4424 in optical light from Hubble. The image is about 45,000 light-years wide. The inset features a close-up view of NGC 4424 that shows Chandra X-ray data (blue) plus a version of the optical data (red) that has had light from a model of NGC 4424 subtracted from the image to show other faint features. This inset image is about 1,700 light-years across. The Nikhuli star cluster is the elongated red object. Image credit: NASA / CXC / Swinburne University of Technology / Graham et al. / ESA / STScI.

The emission from M87* has been resolved into a bright, thin ring (orange colormap), arising from the infinite sequence of additional images of the emission region, and the more diffuse primary image, produced by the photons that come directly toward Earth (in blue contours); when viewed at the imaging resolution of the Event Horizon Telescope, the two components blur together; however, by separately searching for the thin ring, it is possible to sharpen the view of M87*, isolating the fingerprint of strong gravity.
