New Observations of Messier 87’s Black Hole Support Einstein’s Theory of General Relativity

The Event Horizon Telescope Collaboration released new images of M87* from observations taken in April 2018, one year after the first observations in April 2017. The new observations reveal a familiar, bright ring of emission, the same size as as first observed. The brightest part of the ring has shifted by about 30º, to a 5 o’clock position, relative to the 2017 image. Image credit: EHT Collaboration.

In April 2019, the Event Horizon Telescope (EHT) Collaboration reported the first-ever event-horizon-scale images of a black hole, resolving the central black hole — known as M87* — in the giant elliptical galaxy Messier 87 (M 87). In a new paper, astronomers present new images of M87* from data collected by the Atacama Large Millimeter/submillimeter Array (ALMA), the Greenland Telescope and several other instruments within the EHT. These...

This Hubble image shows IC 438, a spiral galaxy some 130 million light-years away in the constellation of Lepus. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This artist’s concept shows the entire sky in gamma rays with magenta circles illustrating the uncertainty in the direction from which more high-energy gamma rays than average seem to be arriving. In this view, the plane of our Milky Way Galaxy runs across the middle of the map. The circles enclose regions with a 68% (inner) and a 95% chance of containing the origin of these gamma rays.

Two spiral galaxies, NGC 6040 and NGC 6039, are merging together at the right side of this Hubble image. NGC 6039 is seen face-on and is circular in shape. NGC 6040 seems to lie in front of the first one. In the lower-left corner, cut off by the frame, the elliptical galaxy NGC 6041 -- a central member of the galaxy cluster that Arp 122 resides in -- appears as light radiating from a point. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera, which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J. Dalcanton / Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA / L. Shatz.

This Hubble image shows various distant galaxies in the constellation of Cetus: most of the galaxies are very small, but there are a few larger galaxies and some stars where detail can be made out; in the center there is an elliptical galaxy with a brightly glowing core and a broad disk; a reddish, warped ring of light, thicker at one side, surrounds its core; a small galaxy intersects the ring as a bright dot.
