AFRICA: A paper was published by scientists from Brown University in Providence, Rhode Island, in which they wrote regarding Mercury’s mysterious black color. Mercury appears darker than Earth’s moon and scientists have long tried to find out the reason behind this.
Moon looks darker compared to other objects in the solar system for the reason that this world has no air and it was affected by ‘darkening’ processes together with bombardment of solar wind and micrometeorite impacts. Thin coating of dark iron nanoparticles forms on its surface as a result of the two processes; therefore it appears darker when it is observed from a distance.
And according to spectral data, Mercury’s surface has very little nanophase iron, which indicates that a different source or different process could be the reason behind its darker appearance.
As per the research that was conducted in March, comets moving towards the Sun’s direction and passing by Mercury are the reason behind the tiny planet’s appearance. A new research has linked comets crash to the strange swirls in the Moon’s surface.
