Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

Question: How many years were there between the death of Charlemagne and the first award of the Charlemagne Prize? Passage:The Charlemagne Prize (; full name originally Internationaler Karlspreis der Stadt Aachen, International Charlemagne Prize of the City of Aachen, since 1988 Internationaler Karlspreis zu Aachen, International Charlemagne Prize of Aachen) is a prize awarded for work done in the service of European unification. It has been awarded annually since 1950 by the German city of Aachen. It commemorates Charlemagne, ruler of the Frankish Empire and founder of what became the Holy Roman Empire, who resided and is buried in Aachen. Traditionally the award is given to the recipient on Ascension Day in a ceremony in the town hall of Aachen. In April 2008, the organisers of the Charlemagne Prize and the European Parliament jointly created a new European Charlemagne Youth Prize, which recognises contributions by young people towards the process of European integration. Patrons of the foundation are King Philippe of Belgium, King Felipe VI of Spain, and Henri, the Grand Duke of Luxembourg.

Question: What was the difference in age of the actor who performed under the stage name David Baron and his wife who appeared at the Connaught Theater during the same period? Passage:A temporary closure during World War II was followed by a period in which the theatre was managed on Seebold's behalf by a group associated with the J. Arthur Rank Organisation, who pursued a policy of employing young actors who later became important figures in film, television and theatre. Glenda Jackson, Susannah York, Charles Morgan, Maria Charles and several others appeared at the theatre during this period. In the 1950s, Alan Ayckbourn appeared in several plays at the Connaught. In 1956, Winston Churchill visited the theatre to see his daughter Sarah perform in Terence Rattigan's play Variation on a Theme. Harold Pinter acted at the Connaught under the stage name David Baron, moving to a house just a few yards from the theatre in Ambrose Place in the 1960s. Pinter's first wife, actress Vivien Merchant acted at the Connaught during this period. Giles Cooper worked with Pinter at the Connaught. Robin Maugham wrote several plays which he directed and premiered at the Connaught, including The Claimant (1962) and Winter in Ischia (1964). Actress Marina Sirtis, perhaps best known for her role on , began her career in repertory at the Connaught in 1976. Actor Robert Blythe has also worked in repertory theatre at the Connaught.
