Now, Hubble used a primary mirror just 2.4 meters (7 feet) across to make these discoveries from a distance of about 340 miles (547 km) from Earth. So imagine what 100,000 dipole antennas spread across a 12x12 miles (20x20 km) area of the Moon can dig up.
That’s what someone named Ronald Polidan from Lunar Resources is proposing through the NASA Innovative Advanced Concepts (NIAC) program. Not a telescope, but a huge, low-frequency radio observatory, built on the surface of the Moon.
Called FarView, it would have to be partially built on-site, using locally-available regolith. Its main goal would be looking far away and back in time as far as what is known as the Cosmic Dark Ages, a period that began some 370,000 years after the Big Bang.
The man behind the idea claims such an array would be unprecedented and would be the “first of its kind at this scale and sensitivity.” The conditions that led to the creation of the first stars, galaxies, and accreting black holes could come into view and greatly expand our knowledge of the Universe.
Like all other ideas in the NIAC program, this one too is at a study level. NASA is backing it but likes to say none of these ideas are guaranteed to morph into actual missions or real-life projects.
