Read More 2026-06-28 Two Exoplanets Fluffier Than Marshmallows Shock Astronomers Astronomers have found two Jupiter-sized exoplanets, TOI-791 b and c, whose densities are even lower than marshmallows. Observed by TESS and Antarctic telescopes, these puffed-up worlds offer clues about formation and composition.
Read More 2026-06-27 Why Terraforming Mars Could Take Centuries to Achieve Terraforming Mars is physically possible but demands staggering mass, heat, oxygen and energy. This article breaks down the five habitability milestones, the material math, and why energy is the ultimate bottleneck.
Read More 2026-06-26 How Giant Impacts Might Explain Earth's Missing Crust New research argues repeated giant impacts in the Hadean may explain why we lack early continental rocks, why cratons are rounded, and how massive unconformities formed. The idea shifts how we read Earth and Moon records.
Read More 2026-06-26 Planetary Flybys May Have Triggered Earth's Mass Extinctions A new hypothesis argues that close flybys by planetary-mass objects from the outer Solar System could have generated colossal tides, volcanic episodes, and climate disruption strong enough to trigger some of Earth's mass extinctions.
Read More 2026-06-25 Scientists Confirm All Five Genetic Letters on Ryugu Scientists analyzing Hayabusa2 samples from asteroid Ryugu have detected all five nucleobases of DNA and RNA, suggesting that key molecular ingredients for life formed in space and were delivered to early Earth.
