"There are a set of undetermined parameters that control the formation and evolution of a dark star, and ultimately, its observable properties," the authors cautioned in the study. JWST's observations suggest that the three distant objects, which all are from early in the universe's history, meet the key characteristics of dark stars: they are luminous, but too cool for fusion to be happening, the July 11 paper in the Proceedings of the National Academy of Sciences stated. (Another inspiration was Crosby, Stills, Nash and Young's 1977 song, also called "Dark Star.") Their interesting moniker comes from the song "Dark Star," first played in 1967 by The Grateful Dead, the research team that first predicted dark stars told in 2009. For about 15 years, scientists have speculated that "dark stars" were among the first our universe ever produced, when it was just 700 million years old. Dark stars, if they do indeed exist, may be key to helping us understand how the universe first got light.
