Titan, An Extraterrestrial World That Resembles The Physical Features Of The Earth

Image
Saturn's largest moon 'Titan', looks very familiar to Earth from space. The moon has rivers, lakes and seas filled by rain falling through a thick atmosphere. Though these landscapes look similar, they are composed of different materials. Liquid methane streams streak Titan's icy surface, and nitrogen winds build hydrocarbon sand dunes.

These materials make Titan's landscape formation mysterious. Researchers at Stanford University have shown how Titan's different plains, labyrinth terrains and dunes could be formed by identifying a process of the formation of sand grains and bedrock depending on how the stream flows and the wind blows. Titan is the only other body in the solar system that has a seasonal liquid transport cycle (precipitation) like Earth. It is also a target for space

China's Chang'E-5 Moon Lander Has Returned With Samples That Contain Water

There are numerous things that astronauts do in space and water is important for a few among those. It is also essential for astronaut landings, survival, and other purposes such as the production of rocket fuel. Researchers in China discovered the first signs of the  presence of water on the moon’s surface . This was done with help of the data obtained from Chang’E-5 lander’s lunar mineralogical spectrometer (LMS).  Professors  LIN Yangting and LIN Honglei of the Chinese Academy of Sciences' Institute of Geology and Geophysics (IGGCAS) were the ones who made the discovery. The study also included researchers from CAS's National Space Science Center, the University of Hawai'i at Mānoa, CAS's Shanghai Institute of Technical Physics, and Nanjing University.
