Sagittarius A, JWST with Chandra & EHT Overlay

Sagittarius A, JWST Known as  Sagittarius A, the Milky Way’s black hole is centered in this infrared from the JWST Nircam camera with Red from the 4.o5u filter, green from the 2.12u filter and blue from the 1.15u filter. Astronomers have found that the X-ray emission originates in hot gas drawn from the winds of massive young stars in the region. This image has an overlay of the Xray emission (in blue) from the Chandra Xray telescope as well as insets from the Chandra and the EHT which show exactly where the black hole is located. Data from the Chandra indicate that only about 1% or less of the gas within the black hole’s gravitational influence ever reaches the event horizon, losing enough heat and angular momentum to fall into the black hole, while the rest of the gas escapes in an outflow.This explains why the Milky Way’s black hole is so quiet, much fainter than might be expected in energetic X-rays. It likely holds for most supermassive black holes in galaxies in the nearby Universe. The image was very difficult to produce because the stars in the image overwhelmed the nebula. All of the stars were removed using StarX Terminator but many stars remained because StarX did not recognize them as stars because they has a black dot in the center. These were removed one by one using a content aware healing brush.
