JWST measures mass of a dormant black hole from the early universe, 6 billion times the mass of our Sun, 10 billion light-years away (opens in new tab)  ⚛️Physics

Carnegie’s Andrew Newman led a team of astronomers that used JWST to make the first direct mass measurement of a dormant black hole at the center of a galaxy from the early universe. Previously, this technique had only been used to study black holes in the local universe. But JWST and a phenomenon called gravitational lensing enabled the researchers to use it on a galaxy that's light is reaching us from when the universe was just 3 billion years old.
