Nobel Prize is not awarded in which field

The Nobel Prizes were originally established in the fields of Physics; Chemistry; Physiology or Medicine; Literature; and Peace. Later an additional award for Economic Sciences was introduced. There is no Nobel Prize in Astronomy as a separate category. However; discoveries in Astronomy are often recognized through the Physics award. For example; Nobel Prizes have been given for research on cosmic radiation; black holes; and exoplanets under Physics. This reflects the flexibility of Nobel recognition; even though the field of Astronomy does not have its own separate prize.
