Astronomers reveal First Image of the Black Hole at the Heart of our Galaxy

EHT image of Sgr A* (top; Paper I). Ring-like images dominate the wide range of images obtained across multiple methods, however, variability and sparse visibility domain coverage make selection of a single image impossible (Paper III). The inset images represent different imaging solutions and their associated frequency (histograms).

Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies...

Dark Heart of the Nearest Radio Galaxy

Distance scales uncovered in the Centaurus A jet. The top left image shows how the jet disperses into gas clouds that emit radio waves. The top right panel displays a color composite image, with a 40⨉ zoom compared to the first panel to match the size of the galaxy itself. The next panel below shows a 165 000⨉ zoom image of the inner radio jet.The bottom panel depicts the new highest resolution image of the jet launching region obtained with the EHT at millimeter wavelengths with a 60 000 000⨉ zoom in telescope resolution. One light year is equal to the distance that light travels within one year: about nine trillion kilometers.
