An impressive image taken by the astrophotographer Andrew McCarthy shows the International Space Station (ISS) passing in front of the Moon, just in front of the prominent Tycho crater, one of the brightest on its surface.
Tycho, with a diameter of 85 km and a depth of 4.8 km, is located in the southern part of the elevated areas of our natural satellite. It was named after the Danish astronomer Tycho Brahe, who studied various celestial objects in the late 16th century.
“That crater is 53 miles in diameter, so even though the station almost appears to be orbiting the Moon, it’s actually 1,000 times closer to us,” at an altitude of 400 km above the surface, the expert said in his twitter accountin which he shares other impressive postcards.

According to McCarthy, the snapshot, taken from the Sonoran desert in Arizona, is one of the “most meticulously planned” he has ever taken.
This difficulty is due to the fact that the great space laboratory travels at a speed of 28,000km/h around the Earth and, in addition, our planet rotates on its own axis at a speed of 1,670 km/h. In this sense, due to the constant movement of both bodies, the image we see is no more than an instant shorter than a second.
“These shots require meticulous planning because you have to be in exactly the right position or the station won’t go exactly where you think,” McCarthy told Petapixel. “If I had set up my telescope on the other side of the clearing I was in, I would have totally missed it,” she added.
In the following video you can see how the ISS transited in front of the Moon in real time from the screen of McCarthy’s laptop, which was connected to the camera of his telescope.
