(AP): For the first time, astronomers have glimpsed the dawn of the universe 13.6 billion years ago when the earliest stars were just beginning to glow. And if that's not enough, they may have detected mysterious dark matter at work, too.

The glimpse consisted of a faint signal picked up by a specialized radio antenna in Australia. If verified, that would be the first confirmation of its kind of dark matter, which is a substantial part of the universe that scientists have been searching for over decades.

The study's lead author is Judd Bowman of Arizona State University. He says the early universe was dark and cold, filled with just hydrogen and helium.

Once stars formed, they emitted ultraviolet light into the dark areas between them. That ultraviolet light changes the energy signature of hydrogen.
