The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon.
Pair of visible-light and near-infrared photos from the Hubble Space Telescope showing the giant star N6946-BH1 before and after it vanished out of sight by imploding to form a black hole NASA/ESA/CSA James Webb Space Telescope image of NGC 6946, revealing large amounts of dust from the two supernovae SN 2004et and SN 2017eaw
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...

GNz7q is a starburst galaxy with a candidate proto-supermassive black hole in the early Universe, at a redshift of 7.1899 ± 0.0005, [2] estimated to have existed only 750 million years after the Big Bang. It was discovered in the Great Observatories Origins Deep Survey-North (GOODS-North) field taken by the Hubble Space Telescope. [3]
NGC 2768 is a lenticular galaxy located in the constellation of Ursa Major. It is at a distance of 65 million light years from Earth. NGC 2768 is an example of a Seyfert galaxy, an object with a supermassive black hole at its centre. A dusty structure is encircling the centre of the galaxy, forming a knotted ring around the galaxy's brightly ...
A team of researchers has captured how the dust surrounding black holes absorbs and reflects the flares produced by a tidal disruption. NASA just captured an incredible look at a black hole eating ...
The Webb telescope, the most powerful ever, targeted the giant black hole at the center of a galaxy known as ESO 428-G14 about 70 million light-years away, according to Space.com.
