Supernova (Chilean band)
Supernova were a Chilean pop band integrated by three girls and was created by Koko Stambuk and Cristian Heyne, influenced by American teen pop of the 90's.
Between 1999 and 2001, Supernova was integrated by Constanza "Coni" Lewin, Elisa Montes and Consuelo "Chi-K" Edwards, and from 2001 to 2003 by Claudia González, Constanza "Koni" Lüer and Sabina Odone. Both groups of girls only recorded one studio album, the first one was Supernova which sold 45,000 copies, and achieving Double Platinum, and the second was Retráctate this one was a Latin Grammy nominee for Best Pop Vocal Album, Duo or Group.
Several times the original group perdormed live on Blondie Discothèque and in 2010 the group returned for a mini tour.

Supernova (Mr Hudson song)
"Supernova" is a song by British singer Mr Hudson with American hip hop artist Kanye West, who is featured on the song. "Supernova" was premiered on 13 May 2009, on Zane Lowe BBC Radio Show and then released through Mr Hudson's and Kanye West's blogs. The song was later remixed by Calvin Harris in a more electronic fashion. After being officially released as a single on 19 July, it promptly debuted high on European charts.
Release

Chart performance
On the Irish Singles Chart, "Supernova" debuted in the top ten, entering at number seven on the issue date of 23 July 2009. The song was the highest debut on the chart for that week. The following week it rose to number four, and peaked at number two. It performed even better in Hudson's native United Kingdom, where it debuted at number two on the UK Singles Chart on 26 July 2009 (for the week ending date 1 August 2009)

Lumen (anatomy)
In biology, a lumen (from Latin lūmen, meaning "an opening"; plural lumina) is the inside space of a tubular structure, such as an artery or intestine. By extension, the term lumen is also used to describe the inside space of a cellular component or structure, such as the endoplasmic reticulum.
Transluminal procedures
Transluminal procedures are procedures occurring through lumina, including:
Lumen (unit)
The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model of the human eye's sensitivity to various wavelengths. Lumens are related to lux in that one lux is one lumen per square meter.
The lumen is defined in relation to the candela as
A full sphere has a solid angle of 4π steradians, so a light source that uniformly radiates one candela in all directions has a total luminous flux of 1 cd × 4π sr = 4π cd⋅sr ≈ 12.57 lumens.
Explanation
If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4π lumens. If the source were partially covered by an ideal absorbing hemisphere, that system would radiate half as much luminous flux—only 2π lumens. The luminous intensity would still be one candela in those directions that are not obscured.
