SDO received these images at a wavelength of UV light, where it can be seen how the solar material heats up to more than 10 million degrees Fahrenheit. Extreme UV-light is usually invisible to the human eye, but satellites allow us to monitor the vortex activity in the atmosphere of our star.
September 9, 2018 NASA's Solar Dynamics Observatory (SDO) received a view of two lunar transits where the Earth’s satellite blocked the Sun. Transit occurs when a celestial body passes between a large object and an observer. The first transit lasted an hour and shielded 92% of the stars at the peak of the passage. The second occurred after a few hours, covering 49 minutes and filling 34% of the Sun.
Transits can be traced in the image. It seems that the moon has changed position and passed again, but here the essence lies in the orbit of the ship itself. The moon has no atmosphere, so sunlight is not distorted, and the outline of the surface of the satellite is clearly visible. It looks smooth, but there are craters, valleys and mountains on the moon.
