Mercury's unusual characteristics and orbit challenge current understanding of planet formation, with theories including giant impacts and migration. The upcoming BepiColombo mission aims to uncover its origins by studying its surface and internal structure, potentially solving one of the Solar System's biggest mysteries.
Astronomers have discovered an exoplanet called TOI-733b, which is just under twice the radius of Earth and is orbiting a star a little smaller than the Sun with a period of 4.9 days. The exoplanet may have lost its atmosphere or be an ocean-covered water world. The discovery could help scientists figure out a curious gap in the exoplanet record: why there are so few worlds between 1.5 and 2 Earth radii.
