June 12 - Mercury at Greatest Eastern Elongation. The planet Mercury will be at its furthest angle from the Sun, known as greatest elongation. It will be at its highest point in the night sky after sunset. This is the best time to try to view Mercury since it stays so close to the Sun and doesn't usually climb very high above the horizon.
The planet Mercury was once an active and dynamic planet, according to new evidence from a Nasa spacecraft. Data from the American Messenger probe shows that impact craters on the planet's surface were distorted by some geological process after they formed.
A close-up view of #Mercury. #Astronomy #SolarSystem New observations from a spacecraft orbiting Mercury have revealed that the tiny, pockmarked planet harbors a highly unusual interior — and the craft’s glimpse of Mercury’s surface topography suggests the planet has had a very dynamic history.
Colors of the Innermost Planet: This image of Mercury was produced by using images from the color base map during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface.
