Why does the female mantis eat the male after mating?

In fact, the female eats the male because of the strong need for proteins at an early stage of egg development.

There is a version that the male unwittingly serves as a necessary source of protein.
After eating the male, the female mantis also dies, immediately after laying eggs in the nest made by her from foamy mucus. And you complain about your life

Multiple images of the Sun obtained by the Solar Dynamics Observatory

SDO carries equipment capable of taking 12 different types of solar images.

A single SDO image is 4,096 by 4,096 pixels, allowing scientists to observe details on the surface of the Sun with an angular size of 0.6 seconds. The apparatus transmits images to Earth every 12 seconds, amounting to about 3 terabytes of data per day.

Between 2010 and 2015, about 2,600 terabytes of data were collected, including 200 million photos.😱

Joseph Kittinger survived G-force of 22g whilst parachuting from 31.3km in 1959. He passed out in a velocity spin before his emergency chute opened, allowing him to live until yesterday. His record stood for 52 years.
