A larger separation between mirrors provides greater resolution. With 100 microarcsecond resolution, astronomers could image the coronae of nearby stars, seeing the actual disks of other stars which appear now only as points of light. The lower the number, the higher the resolution. Through the power of ultra-high resolution, we could journey to distant places without need for a warp drive. We could see stars as clearly as we now see our own Sun.
Scientists value every part of the electromagnetic spectrum.
X rays are ideal for viewing black hole activity because they are produced close to the source and can escape the region without being absorbed by intervening dust. Radio telescopes can provide in-depth observations of black holes as well as a variety of other astronomical phenomena. With a lower flow of matter, radio waves may be the dominant form of radiation. In geometry, a circle is divided into 360 degrees. The full moon is about 30 arc minutes in diameter when viewed from Earth.
