Smallest main belt asteroid detected by James Webb telescope: NASA

European astronomers using the James Webb Space Telescope have detected a previously unknown asteroid about the size of Rome's Colosseum in the main asteroid belt between Mars and Jupiter. The asteroid measuring between 300 and 650 feet (100 to 200 meters) in length is the smallest object observed to date using the telescope, the US space agency NASA said Monday. It was detected during calibration of the telescope's Mid-InfraRed Instrument, which operates in mid-infrared wavelengths.

Potential presence of primitive lunar mantle materials on Chandrayaan-3 landing site: Study

Chandrayaan-3's landing site revealed high sulphur levels, suggesting presence of primitive lunar mantle materials from the South Pole-Aitken basin's formation 4.3 billion years ago, offering insights into early lunar evolution and composition.
