Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Input: original question: What is the galactic interaction type of [Milky Way]?
answer: galactic collision
answer type: Galactic interaction type.
auxiliary information: The Milky Way is the galaxy that contains our Solar System. Its name "milky" is derived from its appearance as a dim glowing band arching across the night sky whose individual stars cannot be distinguished by the naked eye. The term "Milky Way" is a translation of the Latin via lactea, from the Greek Œ≥Œ±ŒªŒ±ŒæŒØŒ±œÇ Œ∫œçŒ∫ŒªŒøœÇ. From Earth the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies‚Äînow known to be billions. The Milky Way is a barred spiral galaxy that has a diameter usually considered to be roughly 100,000‚Äì120,000 light-years but may be 150,000‚Äì180,000 light-years. The Milky Way is estimated to contain 100‚Äì400 billion stars, although this number may be as high as one trillion. There are probably at least 100 billion planets in the Milky Way.

The [Milky Way] was created by what type of galactic interaction?
