2016 Mercury Transit in 4K

It seems like you're asking about Mercury in the year 2016. In 2016, Mercury, the smallest planet in our solar system and the closest one to the Sun, continued to be a subject of interest for astronomers and space scientists. Here are some key points about Mercury in that year:

NASA's MESSENGER Mission: In April 2015, NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) mission came to an end when the spacecraft was deliberately crashed into Mercury's surface. The mission provided a wealth of information about Mercury's composition, surface features, and magnetic field.

Mercury's Atmosphere and Magnetosphere: Scientists were continuing to study Mercury's extremely thin atmosphere (exosphere) and its unique magnetic field. The interactions between the solar wind and Mercury's magnetic field create fascinating phenomena around the planet.
