Largest Supernova Catalog Yet: 2,884 Explosions Hint Dark Energy May Evolve

An international team led by the University of Queensland compiled the largest catalog of 2,884 Type Ia supernovae. The data add to evidence that dark energy may change over time rather than remain constant, as the standard cosmological model assumes.

• Catalog combines 2,884 Type Ia supernovae, including 2024 Dark Energy Survey data
• Older observations were reanalyzed for cosmic dust, galaxy mass and gravitational lensing
• Deviation from the standard model aligns with DESI hints of time-varying dark energy
• The catalog will grow with the DEBASS program
