🌌Galaxies z10 through z13, among the oldest and most distant ever seen, have been discovered.
⭐️These galaxies could be powered by dark matter, leading to the hypothesis of dark stars.
💫Dark stars are super bright and can shine billions of times brighter than the Sun.
🔭Observations of gravitational lensing and spectra could help verify the existence of dark stars.
🌟Dark stars could contribute to the formation of seed black holes in the early universe.
What are galaxies z10 through z13?
—Galaxies z10 through z13 are among the oldest and most distant objects ever seen, discovered as part of the JWST Advanced Deep Extragalactic Survey (JADES).
What are dark stars?
—Dark stars are a hypothetical type of star powered by concentrations of dark matter, shining super bright and potentially billions of times brighter than the Sun.
How can dark matter power dark stars?
—To power dark stars, dark matter needs to have weak self-interaction, a particular type of particle, and the ability to annihilate when particles get close enough together.
How can the existence of dark stars be verified?
—The existence of dark stars can be verified by observing gravitational lensing and analyzing the spectra of these objects.
What is the significance of dark stars?
—Dark stars could contribute to the formation of seed black holes in the early universe and help explain the rapid growth of supermassive black holes.
