The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

The Sun is the star at the center of the Solar System.

The Sun was an afternoon tabloid newspaper, first published under this name in 1910. It was acquired from Associated Newspapers by Fairfax Holdings in Sydney, Australia in 1953, as the afternoon companion to The Sydney Morning Herald. The former Sunday edition, the Sunday Sun was discontinued and merged with the Sunday Herald into the tabloid Sun-Herald at the same time.

Publication of The Sun ceased on 14 March 1988. Some of its content, and sponsorship of the Sydney City to Surf footrace, was continued in The Sun-Herald.

In Greek mythology, Leto (/ˈliːtoʊ/; Greek: Λητώ Lētṓ; Λατώ, Lātṓ in Dorian Greek, etymology and meaning disputed) is a daughter of the Titans Coeus and Phoebe, the sister of Asteria. and mother of Apollo and Artemis.

The island of Kos is claimed as her birthplace. In the Olympian scheme, Zeus is the father of her twins, Apollo and Artemis, the Letoides, which Leto conceived after her hidden beauty accidentally caught the eyes of Zeus. Classical Greek myths record little about Leto other than her pregnancy and her search for a place where she could give birth to Apollo and Artemis, since Hera in her jealousy had caused all lands to shun her. Finally, she finds an island that is not attached to the ocean floor so it is not considered land and she can give birth. This is her one active mythic role: once Apollo and Artemis are grown, Leto withdraws, to remain a dim and benevolent matronly figure upon Olympus, her part already played. In Roman mythology, Leto's equivalent is Latona, a Latinization of her name, influenced by Etruscan Letun.

In the UK the term 'drift' is commonly used to describe any deposits of Quaternary age.

Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed. A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam. Random House dictionary says the origin of the term "drift mine" is an Americanism, circa 1885-1890.

Drift is a more general mining term, meaning a near-horizontal passageway in a mine, following the bed (of coal, for instance) or vein of ore. A drift may or may not intersect the ground surface. A Drift is a horizontal passage underground. A drift follows the vein, as distinguished from a crosscut that intersects it, or a level or gallery, which may do either. All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration.
