Lyot (lunar crater)

Lyot is a large lunar crater that is located along the southeastern limb of the Moon. It lies within the irregular and patchy lunar mare named Mare Australe, and to the south of the crater Hamilton. Due to its location, this formation is viewed at a low angle from the Earth, and its visibility is affected by libration.

The interior floor of this crater has been resurfaced by lava, leaving a dark interior with an albedo that matches the surrounding mare. The outer rim is low and heavily worn, with a perimeter that forms a somewhat distorted circle. The southwest part of the floor and rim is marked by several small, bowl-shaped craters. There is also the remains of a ghost crater to the east of the crater midpoint.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lyot.

Lyot (Martian crater)

Lyot is a large crater in the Vastitas Borealis region of Mars, located at 50.8° north latitude and 330.7° west longitude within the Ismenius Lacus quadrangle. It is 236 km in diameter and was named after Bernard Lyot, a French astronomer (1897–1952). The name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN). Lyot stands out on the flat plains of Vastitas Borealis, which is generally flat and smooth with few large craters. Lyot is the deepest point in Mars's northern hemisphere.

Research published in June 2009 describes evidence for liquid water in Lyot in the past.

Former rivers

Images from Mars Reconnaissance Orbiter show valleys carved by rivers on the floor of Lyot Crater. Scientists are excited because the rivers seem to have formed more recently than others on Mars; water could have flowed in them only 1.25 million years ago. The source of the water is believed to have been ice from nearby glaciers. The river valleys are over 250 meters wide and tens of kilometers long.

Pure (The Lightning Seeds album)

Pure is a compilation album by pop band The Lightning Seeds, released in 1996 and reaching #27 in the UK Albums Chart.

The first of what would turn out to be five compilations Ian Broudie released from 1996 to 2006, Pure, The Lightning Seeds' first release by Virgin, is almost a reissue rather than a compilation, since it consists of all but three of the songs released by Epic on the first two albums, Cloudcuckooland from 1990 and Sense from 1992; the only songs missing are one song from the first album ("Control the Flame") and two from Sense: ("Where Flowers Fade" and "Marooned").

Pure (Miller novel)

Pure is a 2011 novel by English author Andrew Miller. The book is the sixth novel by Miller and was released on 9 June 2011 in the United Kingdom through Sceptre, an imprint of Hodder & Stoughton. The novel is set in pre-revolutionary France and the upcoming turmoil is a consistent theme throughout. It follows an engineer named Jean-Baptiste Baratte and chronicles his efforts in clearing an overfilled graveyard which is polluting the surrounding area. Baratte makes friends and enemies as the cemetery is both loved and hated by the people of the district.

Miller was inspired to write about the Les Innocents Cemetery after reading historian Philippe Ariès's brief description of its clearing and imagining the theatrics that must have been involved. The novel received positive reviews, particularly noting the quality of writing. The novel was awarded the Costa Book Award 2011 for "Best Novel" and "Book of the Year", and was nominated for the Walter Scott Prize and South Bank award.
