The article explores how ancient rocks in South Africa reveal Earth's early history, showing a planet with extensive oceans, volcanic activity, and microbial life over 3 billion years ago, highlighting the violent yet life-sustaining beginnings of our blue planet.
Scientists have discovered a new exoplanet, TOI-733b, located 245 light-years away from Earth. It is slightly smaller than Earth and has a unique atmosphere, which could either be lost or indicate it is a highly irradiated oceanic world. The planet orbits a star smaller than the Sun and completes its orbit in 4.9 days. The proximity to the star suggests that the planet may have lost its atmosphere due to evaporation. The discovery highlights the similarity between TOI-733b and Neptune, suggesting a common shrinking process due to the loss of atmosphere, although the cause of this phenomenon is still unknown.
