"Earth's tilt has an effect during other times of the year - you see more light in the Northern Hemisphere or more light in the Southern Hemisphere, depending on the time of year".
For those who are exhausted by all the recents supermoons, the "super worm moon" will be the last supermoon of the year.
The supermoon - this one is called the Super Worm Moon- will happen at 9:43 p.m. EDT - several hours after the official start of spring. It is also sometimes referred to as the full sap moon, marking the time of year when sugar maples begin to release their sap.
French aviation experts see clear links in 2 Boeing crashes
The plane crashed shortly after takeoff and investigators suspect a flaw in the system's anti-stall system caused it, CNN reports. Boeing said it supports the grounding of its planes as a precautionary step, while reiterating "full confidence" in their safety.
If you look up in the sky Wednesday night, you'll catch the super worm moon - and it'll be the last supermoon for a while. In the northern hemisphere, this results in longer days and warmer weather as the season of Spring settles in.
However the equinox is an important staging post on the annual orbit of the earth around the sun, particularly if you live at 54.5°N like we do in Northern Ireland. This is the first time the two have landed on the same day since March 2000, according to EarthSky.org. In other words, the center of the visible Sun is directly above the equator, making the hours of day and night of equal length - 12 hours. For those below the equator, this marks the start of autumn.
And this year, the equinox brings another celestial marvel - a spectacular supermoon.
By the end of the day, spring will officially have sprung - even if it doesn't feel like yet it in your city.
It takes a year for the earth to orbit the sun, and as it does so our planet spins on its own axis, each revolution taking a day.
