Midnight sun

The midnight sun is a natural phenomenon that occurs in the local summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the sun remains visible at the local midnight. Around the summer solstice (approximately 21 June in the north and 22 December in the south) the sun is visible for the full 24 hours, given fair weather. The number of days per year with potential midnight sun increases the farther towards either pole one goes. Although approximately defined by the polar circles, in practice the midnight sun can be seen as much as 55 miles (90 km) outside the polar circle, as described below, and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year-to-year.

There are no permanent economically autonomous human settlements south of the Antarctic Circle, only research stations, so the countries and territories whose populations experience it are limited to those crossed by the Arctic Circle: Canada (Yukon, Northwest Territories, and Nunavut), Greenland, Iceland, Finland, Norway, Russia, Sweden, and the United States (Alaska). A quarter of Finland's territory lies north of the Arctic Circle and at the country's northernmost point the sun does not set at all for 60 days during summer. In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August. The extreme sites are the poles where the sun can be continuously visible for a half year.

Trent Reznor

Michael Trent Reznor (born May 17, 1965), known professionally as Trent Reznor, is an American singer-songwriter, record producer, and film score composer. As a vocalist and multi-instrumentalist, he has led the industrial rock project Nine Inch Nails since 1988. His first release as Nine Inch Nails, the 1989 album Pretty Hate Machine, was a commercial and critical success. He has since released eight studio albums. He left Interscope Records in 2007 and was an independent recording artist until signing with Columbia Records in 2012.

Reznor was associated with the bands Option 30, The Urge, The Innocent, and Exotic Birds in the mid-1980s. Outside of Nine Inch Nails, he has contributed to the albums of artists such as Marilyn Manson and Saul Williams. He and his wife, Mariqueen Maandig, are members of the post-industrial group How to Destroy Angels, alongside Reznor's fellow composer Atticus Ross and long-time Nine Inch Nails graphic designer Rob Sheridan.

Reznor and Ross scored the David Fincher films The Social Network (2010), The Girl with the Dragon Tattoo (2011), and Gone Girl (2014), winning the Academy Award for Best Original Score for The Social Network and the Grammy Award for Best Score Soundtrack for Visual Media for The Girl with the Dragon Tattoo. In 1997, Reznor appeared in Time's list of the year's most influential people, while Spin magazine has described him as "the most vital artist in music".
