An international team of astronomers, led by Dutch scientists, has discovered a region in our Milky Way that contains many nitrogen compounds in the southeast of a butterfly-shaped star formation disk and very little in the north-west. The astronomers suspect that multiple stars-to-be share the same star formation disk, but the precise process is still a puzzle. The article with their findings has been accepted for publication in Astronomy & Astrophysics.
