Moon dust is hazardous to humans.
β¨Scientists have studied the lunar dust extracted by astronauts.The conclusions were disappointing: the minerals it contains cause lung cancer in humans.To confirm the theory, studies were conducted on the cells.In 90 percent of cases, they diedβ¨

Radiation and Magnetic Field
β¨The interaction of the Earth's magnetic field with the solar wind results in the formation of radiation belts (Van Allen belts), two rings of ionized gas trapped in orbit around the Earth by the magnetic field.
The outer radiation belt has altitudes ranging from 19,000 km to 41,000 km, while the inner radiation belt has altitudes ranging from 7,600 to 13,000 km.β¨

Can human blood boil in outer spaceπ©Έ?
β¨Any liquid has a direct relationship to ambient pressure. The higher the pressure, the higher the boiling point, and vice versa.
π The problem is that while a liquid boil in space, blood will not. Fluids like saliva in the mouth will boil.
However, blood, unlike saliva, is in a closed system, and your veins will hold it under pressure in a liquid state. Even if you are in a complete vacuum, the fact that the blood is closed in the system means that it won't turn into gas and escapeβ¨

How might extraterrestrial civilizations see Earth?
β¨To find out exactly what an outsider might see, scientists used about 10,000 images of our planet taken by NASA's DSCOVR satellite.
Then they scaled down several times to simulate the distance of several light years. On the resulting image, they highlighted the parameters that most characterize the most prominent parts of the Earth.
As a result, the image produced a two-dimensional map of the Earth's surface, reconstructed from light curve readings without any assumptions about its spectral propertiesβ¨
