History

Historical Context

The supernova SN 1987A, observed in 1987, revolutionized astrophysics by providing insights into stellar explosions. The launch of the Hubble Space Telescope in 1990 further advanced this field, enabling detailed studies of cosmic phenomena. Recent findings, such as FXT EP240315A, connect fast X-ray transients to supernovae, enhancing our understanding of cosmic explosions and their implications for stellar evolution.
