Gravitational wave events are named starting with the prefix GW, while observations that trigger an event alert but have not (yet) been confirmed are named starting with the prefix S. [8] Six digits then indicate the date of the event, with the two first digits representing the year, the two middle digits the month and two final digits the day ...
The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects.
Arago spot (1819): Observation of circular diffraction by François Arago, validated a new wave theory of light by Augustin-Jean Fresnel disproving skeptics like Siméon Denis Poisson. Ørsted experiment (1820): Hans Christian Ørsted demonstrates the connection of electricity and magnetism by experiments involving a compass and electric circuits.
This list of space telescopes ... Typical targets for observations include supernova remnants, masers, gravitational lenses, and starburst galaxies. [citation needed]
Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.

This is a list of the highest astronomical observatories in the world, considering only ground-based observatories and ordered by elevation above mean sea level. The main list includes only permanent observatories with facilities constructed at a fixed location, followed by a supplementary list for temporary observatories such as transportable ...
