Hubble has spotted ‘impossible’ light in deep space, and scientists are trying to explain where it came from

Astronomers have spotted a remarkably small yet potent galaxy, MXDFz4. 4, from the universe's nascent stages. This galaxy, observed by Hubble and confirmed by other powerful telescopes, is emitting energetic ultraviolet light, a phenomenon previously thought impossible for its era. This discovery offers an unprecedented glimpse into how early galaxies began to clear the cosmic fog, paving the way for light to travel freely.
