![Mass and radius for a number of potentially habitable ocean worlds. The bullet points show identified ocean worlds: listed from bottom to top: HD 11505b, WASP 35, TOI 157, TOI 1452b, KELT 10b, HD 80883b, HD 221585b, HIP 67537b, K2-18b, Kepler 1980b, HD 50499b, Kepler 1766b, HD 50499c. The green curve gives the mass-radius relation for planets with a water content of > ∼ 30 % (by mass) from [40]. The arrows (and black crosses [right-most one is white]) give the simulation atmosphere models. -- astro-ph.EP](https://astrobiology.newspackstaging.com/wp-content/uploads/2025/10/A-Systematic-North-South-Asymmetry1.png)
Spaceflight studies present novel insights into biological processes through exposure to stressors outside the evolutionary path of terrestrial organisms. Despite limited access to space environments, numerous transcriptomic datasets from spaceflight experiments are now available through NASA GeneLab data repository, which allows public access to these datasets, encouraging further analysis.
