When astronauts close their eyes, they see flashes of light - about once every 3 minutes There is a theory that this phenomenon is due to the effect of
high-energy particles (so-called cosmic rays) hitting the retina. However, it wasn’t confirmed experimentally in any way.
Perhaps the "flash" effect can be explained by some failures in the nervous system #Astroinfo

One of the first to suggest launching something like a satellite into space was the science fiction writer In 1945, Arthur Clarkson suggested that a satellite could be placed in orbit in such a way that it would move in the same direction and at the same speed as the Earth.
So-called "geostationary satellites" could be used for communications.Scientists did not get Clarkson - until October 4, 1957

The first-ever spacecraft collision occurred in 2009 The long-decommissioned Russian military satellite
Cosmos-2251 collided in its orbit with the active
American satellite Iridium-33.
Such collisions are now trying to be avoided as debris can threaten not only other satellites but also the ISS #Spacecraft

The direction of the tail of comet NEOWISE changed due to the Earth's motion Like all comets, the blue ion tail is always directed away from the Sun. Between July 17 and July 25, 2020 (when these images were taken) the Earth was moving in its orbit around the Sun, and because of this the Sun's position in the sky was also changed.
Consequently, the tail shifted #TailOfComet

What causes solar flares ? These phenomena occur because the Sun has its own magnetic field. And flares occur in areas where magnetic fields of opposite polarity collide in a confined space.Even though we already realize what solar flares are,
scientists still can't predict when they will happen. So they commonly take us by surprise

Why can't we see stars during the day? It's all because of the nearest star to us, the Sun. Although the Sun is not the brightest or largest star, the distance between it and our planet is so small that
sunlight literally floods the Earth, making all other weak light invisible #Stars

Western satellites are predicted to collapse Academician Herbert Yefemov predicted the rapid deterioration of Western satellites - we are talking about more than 2,000 apparatuses of the American Starlink constellation and more than 400 apparatuses of the British OneWeb.
"In a decade, these satellites will break down, becoming just unmanageable junk and creating an unprecedented congestion of narrow orbital layers with space debris, with an uncontrollable increase in the number of collisions," he said.
Efremov also noted that satellite constellations will be renewed, and this, in turn, will lead to a further increase in the number of new devices on the Earth's orbit
