Bangladesh, Aug. 16 -- Scientists are preparing to send a suitcase-sized satellite into lunar orbit to probe the universe's earliest days, using the moon's far side to escape Earth's radio noise.

The CosmoCube mission will seek a faint radio signal known as the 21cm line, emitted by neutral hydrogen billions of years ago.

As the signal stretches across billions of years of cosmic travel, its changing wavelength could reveal how the temperature of the early universe evolved, reports The Guardian.

Professor Eloy de Lera Acedo of the University of Cambridge's Cavendish Laboratory, who is leading the project, said the signal functions like a thermometer for the early cosmos, revealing conditions from roughly 380,000 years after the Big Ba...
