Dark matter influences cosmic behavior through gravitational interactions, leading to phenomena like “dark stars,” which may explode similarly to supernovae. The exploration of potential dark matter particles, such as WIMPs and axions, is critical to understanding these celestial events. Credit: SciTechDaily.com
A possible candidate for a dark matter particle, made up of a hypothetical class of weakly interacting massive particles would rival that of a supernova . Given that dark matter far outweighs the visible matter in the universe, this would surely leave a sign in our observations of the sky. We have yet to find such scars, but the new study gives us something to look for.say that the surrounding gas, made of normal matter, would absorb this extra energy from the explosion and emit some of it back.
What if observations will not detect the predicted signal? That probably won’t rule out this theory completely, as other “axion-like” particles are still possible. A failure of detection may indicate, however, that the masses of these particles are very different, or that they do not couple with radiation as strongly as we thought.
These WIMP-powered dark stars are predicted to be supermassive and to live only for a short time in the early universe. But they could be observed by the James Webb space telescope. A recent study has claimedNevertheless, the excitement about axions is growing, and there are many plans to detect them.

Astronomers find evidence that blue supergiant stars can be formed by the merger of two starsAn international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades.
