New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery
A new study on PDS 70b, a forming exoplanet located 400 light-years away, reveals a significant mismatch between its atmospheric composition and the surrounding protoplanetary disk. This discovery casts doubt on existing planet formation models, suggesting that more research is needed to understand how planets gather materials and elements during t...

Sun Has More Oxygen and Metals, States New Study Its Chemical Composition
Astronomers have solved a decade-long conflict between the Sun's internal structure as determined by solar oscillations (helioseismology) and the structure derived from the fundamental theory of stellar evolution, which is based on measurements of the present-day Sun's chemical composition. The new estimates put an end to a decade-long debate conce...

'Sunscreen' Layer on Distant Exoplanet Discovered
In what could reveal the composition of a planet and how it formed, a team including an Indian-origin researcher has detected a stratosphere, one of the primary layers of Earth's atmosphere, on a massive and blazing-hot exoplanet.

Acidic Oceans Implicated in Earth's Worst Mass Extinction
It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs.
