In March 2025, the International Space Science Institute (ISSI) in Bern hosted an inspiring week-long workshop titled “What’s under the H₀od? Towards Consensus on the Local Value of the Hubble Constant”, bringing together some of the world’s leading cosmologists to tackle one of astronomy’s most puzzling problems: the rate at which the universe is expanding. Among them was Prof. Dr. Adam Riess, Nobel Prize-winning astrophysicist from Johns Hopkins University, who co-convened the workshop and also gave a widely attended public lecture as part of ISSI’s outreach series.
The current state of Venus is the result of the cumulative effects of many processes from the planet’s formation, and its magma ocean phase up to present-day. Venus’s interior thermal evolution, volcanic, tectonic and outgassing history, as well as interaction with the atmosphere have left clues to piece back together what made Earth and Venus evolve differently. Therefore, due to its position at the inner edge of the Solar System habitable zone (HZ), Venus evolution through time provides insights on surface habitability of rocky exoplanets.
