Astronomy and space exploration data

Code for collecting and visualization of astronomical data

All code and description are available at gvard.github.io

Observational astronomy

• First light of notable observatories and instruments See also First light dates of notable observatories with areas of main mirrors. Years 1990-2008 and distribution of diameters of big telescopes.
  Data as JSON.
  First light article (in Russian); inspired by prof. Vladimir Panchuk and his site Астрономические телескопы (in russian).

Solar System objects
