2. Time switch - Wikipedia

   en.wikipedia.org/wiki/Time_switch

   An astronomical (or astronomic) timer calculates dawn and dusk times (tracking the sun position) for each day of the year based on the latitude and longitude (or just north/central/south and time zone on more cheaply made ones), and the day of the year (month and date), programmed by the user upon installation in addition to the usual time of day, except in the case of GPS enabled astronomic ...

   Note the observer's chair between the piers, and the narrow opening in the wall and roof for access to the sky. Because the telescope observes only in the meridian, no rotating dome is necessary. Meridian circles required precise adjustment to do accurate work. [17] The rotation axis of the main telescope needed to be exactly horizontal.

7. Neutrino astronomy - Wikipedia

   en.wikipedia.org/wiki/Neutrino_astronomy

   Neutrino astronomy is the branch of astronomy that gathers information about astronomical objects by observing and studying neutrinos emitted by them with the help of neutrino detectors in special Earth observatories. [1] It is an emerging field in astroparticle physics providing insights into the high-energy and non-thermal processes in the ...
