Beyond Our Solar System: Hunting for Planets and Tsunamis.

Scientists have identified five exoplanets that are most likely to resemble Venus in terms of their radii, masses, densities, the shapes of their orbits, and distances from their stars. These planets are potential analogs of Earth's "twin" and could reveal valuable insights into Earth's future and the risk of developing a runaway greenhouse climate as Venus did. The James Webb Space Telescope will observe these possible Venus analogs to learn if things were ever different for Venus. The observations may reveal biosignature gases in the atmosphere of an exoVenus, such as methane, methyl bromide, or nitrous oxide, which could signal the presence of life.
