The Sun ~ Moon ~ Earth Cycle

The ever-changing Moon orbits around the Earth and, together with the Sun and our tilted planet, causes the seasons and cycles as we know them. When these three planets align exactly, they present us with fascinating events, such as Full Moons, some Super Blood or Blue Moons, Eclipses, Solstices, and Equinoxes.

Dark Moon
The day before a new Moon, when the Moon is not visible, is called the Dark Moon.

New Moon
The Moon is positioned between the Earth and the Sun; therefore, it is not visible from Earth.

Full Moon
During a full Moon, the Moon and Sun are opposite, with the Earth in between. From Earth, we see it fully illuminated by the Sun’s rays.

Supermoon
A Supermoon occurs at either a full or new Moon, which coincides with the Moon’s closest approach to the Earth (perigee). Therefore, Supermoons appear bigger and brighter than usual and cause higher tides, namely, perigean spring tides.

Blue Moon ~ Black Moon
A Blue Moon occurs when two full Moons rise in the same calendar month, and a Black Moon occurs when two new Moons rise in the same zodiac sign or calendar month. Folklore also suggests that if a season has four full Moons, the third one is referred to as a Blue Moon. The third new Moon is called Black Moon. This happens approximately every 33 months, and two Blue/Black Moons in one year occur roughly once every 19 years. Blue/Black Moons never happen in February!

Lunar and Solar Eclipse
Eclipses are natural phenomena and only happen at those new and full Moons when the Sun, Moon, and Earth line up exactly, which usually occurs four times a year and always in pairs, a fortnight apart.
Lunar Eclipse
A lunar eclipse happens only at a full Moon when the Sun and Moon are opposite. The Earth passes between the Sun and the Moon and partially or fully blocks (occults) the Sun’s rays, overshadowing the Moon.
You can safely observe a lunar eclipse without eye protection.
Solar Eclipse
A solar eclipse happens on the new Moon when the Moon passes between the Earth and the Sun. It partially or fully blocks (occults) the Sun’s rays, causing the sky to darken. It is crucial to never watch a solar eclipse without protective eyewear or shields.

Blood Moon
A full Moon that is fully eclipsed often turns red and is called a Blood Moon. This is due to a phenomenon named ‘Rayleigh Scattering’, a scattering of light that also causes spectacular sunrises and sunsets.

March Equinox and September Equinox
Twice a year, when the Sun crosses the celestial equator, day and night are of equal length. The March equinox, known as Mabon, marks the beginning of autumn in the southern hemisphere. The September equinox, known as Ostara, marks the beginning of spring in the southern hemisphere.

Summer and Winter Solstice
Summer solstice, Litha, marks the longest day of the year. The Sun reaches its highest point in the sky at noon and is most intense. Winter solstice, known as Yule, marks the shortest day of the year when the Sun is at its lowest point in the sky at noon and is at its least intense.
