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: When did the person die who had a long feud with FDR? Passage:Roosevelt came to office in 1929 as a reform Democrat, but with no overall plan. He tackled official corruption by dismissing Smith's cronies and renamed the New York Public Service Commission. He addressed New York's growing need for power through the development of hydroelectricity on the St. Lawrence River. He reformed the state's prison administration and built a new state prison at Attica. He had a long feud with Robert Moses, the state's most powerful public servant, whom he removed as Secretary of State but kept on as Parks Commissioner and head of urban planning. Moses was replaced with the Bronx's Democratic Boss Edward J. Flynn. When the Wall Street crash in October 1929 ushered in the Great Depression, Roosevelt started a relief system that later became the model for the New Deal's Federal Emergency Relief Administration (FERA). Roosevelt followed President Herbert Hoover's advice and asked the state legislature for $20 million in relief funds, which he spent mainly on public works in the hope of stimulating demand and providing employment. Aid to the unemployed, he said, "must be extended by Government, not as a matter of charity, but as a matter of social duty." In his first term, Roosevelt famously said, "The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written." He was referring to the belief he had that the Federal government would need to use more power in order to bring the country out of the Depression.

Passage:In April 2005, Mill a h-Uile Rud embarked on a European tour with Oi Polloi which took in Scotland, Belgium, the Netherlands, Germany and Poland. Much of this tour was filmed by BBC Alba for a Gaelic television documentary on Mill a h-Uile Rud and Gaelic punk. They have also played in Stornoway, on the sparsely populated Isle of Lewis, the largest town in the Western Isles of Scotland. They also recorded a live session for the BBC Radio nan Gaidheal nighttime 'Rapal' program which is broadcast nationally in Scotland. In 2005, Tim moved to Scotland full-time to study sociolinguistics and language revival—he is a lecturer at Sabhal Mòr Ostaig—and as such, the band is less active, although they still play from time to time when Tim is back in the Seattle. Tim was also involved in the Gaelic techno/hip-hop act, Nad Aislingean, the Gaelic rock band, Na Gathan and in 2013 published Air Cuan Dubh Drilseach, the first Scottish Gaelic science fiction novel, published by CLÀR. The book was launched in Edinburgh with Mill a h-Uile Rud's contemporaries Oi_Polloi at an illegal street gig on Leith Walk outside Elvis Shakespeare, and later at The Cruz boat on The Shore with Comann Ceilteach Oilthigh Dhun Eideann and CLÀR. Sgrios remains quite active in the Seattle folk-punk scene and is involved in a number of bands in the city while Sìne now runs a goat cheese farm outside of Seattle and researches farming culture. Only their roadie, Erin, still lives on the remote punk commune in the mountains outside Seattle where the band was formed.
