Astronomy has lost one of its most assiduous calculators of eclipses with the passing of astronomer Fred Espenak.
On April 15, 2025, Espenak announced on his Facebook page that he had idiopathic pulmonary fibrosis, his health was declining rapidly, and that he would immediately be entering hospice care. Doctors determined that the disease had progressed too far for a lung transplant. He passed away peacefully on Sunday, June 1 at his home in Portal, Arizona. He was 71.
