Astronomers have captured a rare glimpse inside HOPS-315, a young star that appears to sit at the center of a nascent version of our own solar system.

Weighing in at 0.6 solar mass, HOPS-315 should someday grow to become a star much like our own sun; this makes it a promising stand-in for studying the first stages of our solar system’s history. For ...

A young sunlike star called HOPS 315 seems to host a swirling disk of gas giving rise to minerals that kick-start the planet formation process.
