The Third Quarter Moon is one of the four main lunar phases, also called a Half Moon. It occurs when the Moon is at an angle of 90 degrees to a line between the Earth and the Sun. In this position we see half of the Moon illuminated and the other half in shadow. The First Quarter phase is also called a Half Moon. The term Third Quarter is used during the \"waning\" phase, when the lit part of the visible side of the Moon is decreasing day by day.

Conversely, in the southern hemisphere it is the day with the longest daylight hours. There it marks the start of the summer, and is referred to as the \"summer solstice\". The date of the solstice varies between December 20 and 22, because it is delayed by about 6 hours each year, to be set back again at every leap year. In 2026, the December solstice falls on 21 December.

The Third Quarter Moon is one of the four main lunar phases, also called a Half Moon. It occurs when the Moon is at an angle of 90 degrees to a line between the Earth and the Sun. In this position we see half of the Moon illuminated and the other half in shadow. The First Quarter phase is also called a Half Moon. The term Third Quarter is used during the \"waning\" phase, when the lit part of the visible side of the Moon is decreasing day by day.

At the equinox everybody on Earth experiences a day and night of equal lengths, 12 hours of daylight and 12 hours of night time. In astronomical terms it is the exact moment the Sun crosses the celestial equator — the imaginary line in the sky above the Earth’s Equator — from north to south. In 2026, the September equinox falls on 23 September. In the northern hemisphere, after the September equinox, daylight hours start to be shorter, and it's thus considered as the beginning of the season of Autumn. The opposite happens in the southern hemisphere, with the beginning of Spring.

A partial lunar eclipse happens when the Sun, the Earth and the Moon are approximately, but not exactly, aligned in space, and the Moon is full. The Earth prevents the Sun's light from reaching the Moon's surface directly. Part of the Moon is obscured within the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon falls within the outer part of the Earth's shadow, called the penumbra. The Moon will appear a bit dimmer than usual. This eclipse will be visible in Europe, the western part of Asia, Africa, North America, South America, the Pacific, the Atlantic, the Indian Ocean, and Antarctica.

The Full Moon is one of the four main phases of the Moon. It occurs when the Sun, the Earth and the Moon are approximately aligned, and the Moon and the Sun are on opposite sides of the Earth. In this arrangement the entire sunlit part of the Moon faces us. A Full Moon is sometimes called a “Supermoon” when the Moon is at its closest distance from Earth, as it then appears bigger and brighter than usual.

Such apparent celestial near misses — although the heavenly bodies are actually tens to hundreds of millions of kilometres apart — are called conjunctions.

Still other sights delight this night view at Paranal : the radiant, reddish plane of the Milky Way, smouldering on the horizon, and an 8.2-metre VLT Unit Telescope, along with a 1.8-metre Auxiliary Telescope, standing firmly on the ground.

A lunar eclipse occurs when the Moon passes directly behind the Earth and into its shadow. This can occur only when the Sun, Earth and Moon are almost exactly aligned. Hence, a lunar eclipse can be seen only on the night of a full Moon. During totality the Moon turns red: this happens because some of Sun's light filters through the Earth's atmosphere, such that the blue colours are scattered away and the red colours are bent towards the Moon. This eclipse will be visible in the East of Europe, Asia, Australia, North America, South America, Pacific, Atlantic, Indian Ocean, Arctic, and Antarctica.

The Third Quarter Moon is one of the four main lunar phases, also called a Half Moon. It occurs when the Moon is at an angle of 90 degrees to a line between the Earth and the Sun.

The meteors appear to radiate from a point on the sky in the constellation of Leo, close to the “Sickle stars” that are above Regulus. Up to 10 shooting stars an hour can be seen at the peak, for approximately three days around 17 November 2025. They are best viewed from a dark location after midnight.
