The James Webb Space Telescope (JWST) may have discovered something incredible: a possible dark star in the far reaches of the Universe. This could help solve some big mysteries in physics.
What’s a dark star? It sounds confusing, but these stars still emit light and energy. Unlike regular stars that burn through nuclear fusion, dark stars rely on dark matter particles interacting at their core.
According to Cosmin Ilie, an astrophysicist at Colgate University, “Supermassive dark stars would be huge, bright clouds mostly made of hydrogen and helium,” held up by their own dark matter annihilation.
Researchers studying some of the most distant objects ever seen found evidence suggesting they might be dark stars. One object showed a unique light absorption feature that appears to signal dark stars—a sign of singly ionized helium in their atmospheres.
Ilie notes, “Even though the signal-to-noise ratio is low, this is the first potential smoking gun for dark stars. That’s a big deal.” This finding could reshape our understanding of the Universe.
Since JWST launched in 2021, it has spotted unexpected sights. Among them are massive galaxies existing when there shouldn’t have been enough time for them to grow so large. Astrophysicists suggest dark stars, which can hold up to a million times the mass of our Sun, might explain these observations.
The recent study evaluated four objects, with one appearing as a point source and the others suggesting they might be dark stars surrounded by clouds of ionized hydrogen and helium. However, researchers admit these could still just be galaxies, which raises more questions about the Universe’s evolution.
Dark stars not only offer clues about dark matter but could also shed light on how supermassive black holes formed early in the Universe. Their collapse could create black holes with large masses—something many current theories struggle to explain.
This research highlights how much we still have to learn about the cosmos. The findings were published in the journal PNAS.
As we gather more data from JWST and other telescopes, the door remains open for groundbreaking discoveries that may change our understanding of the Universe forever.
