The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA missions
dealing with extremely energetic phenomena, from black holes to the Big Bang. Having recently merged with the Legacy
Archive for Microwave Background Data Analysis (LAMBDA), it includes data
obtained by NASA's high-energy astronomy missions from the extreme ultraviolet through gamma-ray bands, along with
missions that study the relic cosmic microwave background.
