A suitcase-sized satellite may unlock the secrets of the early universe
Reported byPopular Science ↗·Sourced by Goodlede
An international team of astronomers has proposed CosmoCube, a carry-on-suitcase-sized satellite designed to orbit the moon and listen for the 21-centimeter line signal from the universe's first 150 million years—a period never directly observed—by using the moon as a shield from Earth's radio interference.
This is a proposed mission; it has not yet launched.
