SN Ares to Reappear in 2086 Through Gravitational Lensing, Say Scientists

Using gravitational lensing by a foreground galaxy cluster, scientists predict the lensed supernova SN Ares will reappear in 2086, with a 60-year light-delay that could enable ultra-precise cosmology and improved measurements of the Hubble Constant; a second lensed event, SN Athena, may reappear within 1–2 years, offering an earlier data point.

New Evidence Deepens the Universe's Mysteries and the Hubble Tension

Researchers at the University of Tokyo have used a new method involving gravitational lensing to measure the universe's expansion rate, providing evidence that the discrepancy known as the Hubble tension is likely due to real physics rather than measurement errors, with their findings aligning with current local measurements rather than early universe estimates.
