An illustration of a protoplanetary disk. The solar system formed from such a disk. Astronomers suggest this birthplace was protected by a larger filament of molecular gas and dust early in history.Roughly 1,000 light-years from Earth, there is a cosmic structure known as IRAS 23077+6707 that resembles a giant butterfly.. To the surprise of many, the structure has remained unchanged for years, leading some to question what IRAS 2307 could be.
Protoplanetary disks are basically planetary nurseries consisting of the gas and dust that have settled around newly formed stars. Over time, these disks become rings as material coalesces into protoplanets in certain orbits, where they will eventually become rocky planets, gas giants, and icy bodies.
When the Pan-STARRS and SWA teams observed IRAS 23077 using the combined power of their observatories, they were quite surprised by what they saw. "The data from the SMA offer us the smoking–gun evidence that this is a disk, and coupled with the estimate of the system's distance, that it is rotating around a star likely two to four times more massive than our own Sun.
