The Sun
The Sun is a yellow dwarf star (G2V), about 4.6 billion years old, and the dominant gravitational force in the Solar System. It has a diameter of roughly 1.4 million kilometers and contains around 99.8% of the Solar System’s mass. Nuclear fusion in its core converts hydrogen into helium, producing energy that warms the planets. Above the core lie the radiative and convective zones, followed by the visible photosphere (~5,500 °C), the chromosphere, and the much hotter corona (~2 million °C).

The Full Moon and the Dancer
22/01/2022
On Monday, January's Full Moon rose as the Sun set. Spotted near the eastern horizon, its warm hues are seen in this photo taken near Cagliari, capital city of the Italian island of Sardinia. Of course the familiar patterns of light and dark across the Moon's nearside are created by bright rugged highlands and dark smooth lunar maria. Traditionally the patterns are seen as pareidolia, giving the visual illusion of a human face like the Man in the Moon, or familiar animal like the Moon rabbit. But for a moment the swarming murmuration, also known as a flock of starlings, frozen in the snapshot's field of view lends another pareidolic element to the scene. Some see the graceful figure of a dancer enchanted by moonlight.
