Question

Why the phases of the moon repeat every 29days?
Give reasons for the explosion of stars.​

Answer 1

Answer:

Explanation:

The moon phase name is shown alongside the image. The dotted line from the earth to the moon represents your line of sight when looking at the moon. ... So the basic explanation is that the lunar phases are created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth.

It changes in the same pattern approximately every 29 days because as different parts of the moon's surface are struck by sunlight as the moon revolves around Earth, different phases of the moon can be seen. A lunar eclipse occurs when the moon passes through Earth's shadow.

It's a balance of gravity pushing in on the star and heat and pressure pushing outward from the star's core. When a massive star runs out of fuel, it cools off. This causes the pressure to drop. Gravity wins out, and the star suddenly collapses.
