WebA 200mW green laser will be visible for up to 10 miles on a clear day, and a 1,000mW blue laser will be similarly visible. Various environmental factors like fog and clouds can affect how far your beam will be visible, but as a general statement, you should anticipate over 10 miles of visibility with 200mW+ green lasers and 1,000mW+ blue lasers. WebUnseen Galaxies. At distance 10 Gly the frequency of light from a sun-like star emitting at 525 THz (yellow range) drops below the visual threshold of 400 THz. Thus, we have no way of knowing how many stars farther than 10 Gly away may be invisible to us. The Hubble Space Telescope creates for us a spherical horizon with radius of 13.4 Gly.
