A solar system similar to our own may be taking shape in the Taurus constellation.

The young star DM Tau, which lies about 470 light-years from Earth, was already known to host a ring of dust where planets are likely forming. But recent observations by the powerful Atacama Large Millimeter/submillimeter Array (ALMA) in Chile show there's considerably more to the story.

"Some studies suggested the radius of the ring is about where [our] solar system's asteroid belt would be. Other observations put the size out where Neptune would be," Tomoyuki Kudo, an astronomer at the National Astronomical Observatory of Japan, said in a statement.

"Our ALMA observations provided a clear answer: Both are right," added Kudo, the lead author of a recent study reporting the results. "DM Tau has two rings, one at each location."
