NASA has postponed the astronauts' spacewalk.

There was the first case when the exit was canceled due to space debris.

People have polluted even space

How to distinguish stars and planets in the night sky?

To answer this question, you need to determine whether an object is flickering or shining with a steady light. If it flickers, it's a star; if it doesn't, it's a planet.

The reason stars flicker is the Earth's atmosphere. It constantly moves: cold air goes down, warm air goes up, and its density at different heights is heterogeneous. Therefore, as it passes through the Earth's atmosphere, starlight is repeatedly scattered and refracted.

The planets do not flicker because they are much closer to us. Our eye recognizes them as luminous disks. We see their light as smooth and static.
