Astronomers have found distinct spiral arms in the disk of gas and dust surrounding the young star Elias 2-27. While similar features have been observed on the surfaces of such disks before, this is the first time they have been identified within the disk, where planet formation takes place. Structures such as these could either indicate the presence of a newly formed planet, or else create the necessary conditions for a planet to form. As such, the results are a crucial step towards a better understanding how planetary systems like our Solar system came into being.
