What is the scientific explanation of the moon's absence?

User Avatar

Asked by Wiki User

The moon doesn't always rise and set at night, sometimes it rises and sets during the day.

This is dependent on the phase of the moon.

The moon circles the earth once every 28 days.

The closer to full the moon is, the more hours it spends in the sky at night, because it is on the opposite side of the earth as the sun. That's why it is full - the sun is behind you, lighting the moon in front of you. A completely full moon will rise as the sun sets, and set as the sun rises, and will be visible all night.

The closer to "new" the moon is, the fewer hours it spends in the sky during the night, and the more time it spends during the day because it is on the SAME side of the earth as the sun. It appears "new" because the sun is behind it, lighting the far side of the moon. A completely new moon will rise and set with the sun, and will only be visible in the day.. or briefly at dusk.

A half-moon is up half the day and half the night. If you don't see a half-moon at night, it has either already set or hasn't risen yet.

Why is a wormhole called a wormhole and can we use them to travel through time?

User Avatar

Asked by Wiki User

A wormhole is named because it's thought to resemble a tunnel made by a worm boring through an apple. Theoretically, wormholes could allow for faster-than-light travel, but there is no evidence to suggest they can be used for time travel. Time travel through wormholes remains a concept largely explored in science fiction.

Why doesn't it get dark in St Petersburg Russia during June and July - even though the sun actually sets?

User Avatar

Asked by Wiki User

St. Petersburg, Russia experiences the phenomenon of "White Nights" in June and July due to its high latitude. During this time, the sun only dips below the horizon briefly, keeping the sky bright throughout the night. This unique phenomenon occurs because St. Petersburg is located near the Arctic Circle, where the sun does not fully set during the summer months.

Why do the areas near the equator only have twelve hours of daylight - even though they are always tilted towards the sun?

User Avatar

Asked by Wiki User

Areas near the equator receive roughly 12 hours of daylight throughout the year because the equator receives the most direct sunlight, leading to a nearly equal length of day and night. The tilt of the Earth’s axis contributes to longer days and shorter nights in summer and the reverse in winter, but near the equator, this effect is minimal due to the direct angle of sunlight.

How can you tell the difference between astronomical twilight and night?

User Avatar

Asked by DiamondXmas

Astronomical twilight is the period when the sun is between 12 and 18 degrees below the horizon, resulting in a dark blue sky with no sunlight. Night follows astronomical twilight, when the sun is more than 18 degrees below the horizon and the sky is completely dark with no sunlight.
