Scientists used the James Webb Space Telescope to study a tiny galaxy more than 13 billion light-years away. Because the light took so long to reach us, Webb is letting researchers peek at the Universe when it was extremely young.
In that faraway galaxy, they looked at glowing gas swirling around a black hole—like leaves circling a drain, but in space. By tracking how the gas moves, scientists can estimate how massive the black hole is, since a heavier object pulls more strongly.
The surprising clue is that the black hole seems so big that it may have formed very early—possibly before its galaxy was fully built. Scientists have ideas for how that could happen, like huge gas clouds collapsing quickly into a “seed” black hole, or smaller black holes growing fast by pulling in lots of gas.
Webb is especially helpful because it can detect faint infrared light, a bit like night-vision for the ancient Universe. Findings like this don’t mean black holes are coming near Earth—they’re extremely far away—but they do help scientists piece together how galaxies and black holes grew up together over time.
