WebThe light arriving here from the Sun at the H-alpha frequency (656.28 nanometers) comes from a rarified layer of hydrogen gas slightly above the photosphere, the bright surface of the Sun. This hydrogen layer is called the solar chromosphere, and it’s invisible without using instruments to filter out brighter, competing bandwidths of light. WebNov 17, 2024 · Hydrogen alpha viewing of the Sun It is far more difficult to make a hydrogen alpha filter than a broadband filter, and for these reasons they are much more expensive. … WebOct 15, 2024 · Its nearest stellar neighbor is the Alpha Centauri triple star system: red dwarf star Proxima Centauri is 4.24 light-years away, and Alpha Centauri A and B – two sunlike stars orbiting each other – are 4.37 light-years away. A light-year is the distance light travels in one year, which equals about 6 trillion miles (9.5 trillion kilometers). marco\\u0027s pizza mccalla al
