M31 The Andromeda`s Halo - The Andromeda Galaxy
It is the closest large spiral galaxy to our Milky Way😱
This galaxy is 2.5 million light-years away and can be seen in the Earth's night sky as a small, dim, elongated cloud, barely visible to the naked eye.
Emerging star
Hubble has detected a new star, Earendel, Morning Star (WHL0137-LS), which is the farthest star on record from Earth. (WHL0137-LS).
The astronomical object is 12.9 billion light years away!
Zodiacal light
A faint glow observed shortly after sunset or just before sunrise.
This effect is created by cosmic dust - the microscopic remnants of comets, asteroids, and stars.
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.
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.
This photo depicts not a cosmonaut, but l the RadioScape-1 satellite
It was created on the basis of Orlan-M spacesuit hull. Inside the empty space suit there were three batteries, a radio transmitter and internal sensors for measuring temperature and battery charge.
Unfortunately, the RadioScape-1 mission was not a success. It ceased working after two turns around the Earth due to battery failure.
