Now is a great time for binoculars and telescopes.

Lately I’ve been observing the Moon, Jupiter along with 4 of its moons, and the Orion Nebula.

Good morning😊☕

I still don’t understand how come the moon synchronously rotates around the earth and showing us only 1 face all the time

The Moon always shows the same face to Earth because it is tidally locked. This means that the Moon's rotation period on its axis is the same as its orbit around Earth, taking about 27.3 days for both. As a result, the same side of the Moon always faces Earth.

This phenomenon occurs due to gravitational interactions between Earth and the Moon. Over time, Earth's gravity has slowed the Moon's rotation to match its orbital period, a process known as synchronous rotation. The gravitational forces cause tidal bulges on both bodies, and these forces eventually lead to tidal locking.
