The Gruber Cosmology Award was established in 2000 by cosmological businessman Peter gruber, and is awarded once a year. Award outstanding astronomers, cosmologists, physicists, mathematicians or philosophers of science.
In addition, many countries have their own highest astronomical awards:
China Astronomy's Highest Prize-Yuzhe Zhang Prize
The highest prize of French Astronomical Society-Pierre Janssen Prize.
Spinoza prize, the highest prize in Dutch science
etc
In addition, the gruber Foundation Cosmology Award was jointly established by the gruber Foundation and the International Astronomical Union to reward scientists who have made outstanding contributions in the field of cosmology.
I wonder which is the highest award for astronomers?
