Here’s what you’ll learn when you read this story:Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of years ago. Observing this early phase of evolution around a protostar will allow scientists to learn more about the formation of our own Solar System. If our Solar System had baby pictures from over 4.5 billion years ago, they would look something like the otherworldly swirls of dust and gas surrounding the young star HOPS-315. When our Solar System was forming, the temperature around proto-Earth is thought to have been around 327 degrees Celsius (620 degrees Fahrenheit). Some of these flecks are even older than the Solar System itself—the presolar grains in the Murchison meteorite, for instance, go back 7 billion years.
