FarView Observatory
A proposed radio telescope on the Moon's far side made of more than 100,000 antennas built from lunar materials, meant to study the universe's dark ages before the first stars formed.
Why it matters
The far side of the Moon is shielded from Earth's radio noise, which makes it one of the quietest places to listen for faint signals from the young universe. Building the array from local metal avoids launching tons of hardware.
How the technology works
The concept uses metals extracted and processed on the Moon to make simple dipole antennas in place, spread over about 200 square kilometers of the far side to work together as one telescope.
