The LEGO Ideas Astronomy theme focuses on sets that are scientific and space based projects such as real world builds like the NASA Curiosity rover to NASA Apollo Saturn V rocket as well as fantasy space projects like the Exo-Suit.
The LEGO Ideas theme, formally known as LEGO Cuusoo, is based around a website which allows users to submit ideas for Lego products to be turned into potential sets available commercially. If fellow users in the LEGO Ideas community up vote the project to 10000 then LEGO Group has a committee which votes on whether to build the set and release it. If the project is approved and cleared for production, it is developed and later released as an official set under the "LEGO Ideas" banner.
2014 LEGO Sets
2014 was a very important year for LEGO. With the release of The LEGO Movie at the beginning of the year, LEGO was introduced to a whole new generation and population of LEGO lovers, collectors and investors. In addition to the movie, LEGO celebrated the 15th anniversary of LEGO Star Wars and even more important was the decision to continue the Ninjago theme which was originally slated to be discontinued. 2014 also gave collectors the minifigure-scale Minecraft theme based off the widely popular game. New themes that year included Juniors, The LEGO Movie, Mixels, The Simpsons, Ultra Agents, Fusion and Disney Princess. In addition, we did see a number of discontinued themes such as Galaxy Squad, Lone Ranger and The Lord of The Rings.
