A team of scientists has made space history: they're watching as several exoplanets are born.

They've observed the birth of , the team said in its findings, which were recently published in the journal Nature. The new planets are some , according to Space.com. These observations could give scientists more insight , the Los Angeles Times said.

"Such an understanding of the young planet population will shed light on the decades-old problem of planet formation, and reveal how young planetary systems can evolve into older ones such as our solar system, billions of years after they were born,"Zhaohuan Zhu of Princeton University, who is not affiliated with the study, wrote in a separate piece published in the same edition of the scientific journal.

The study, which was led by University of Arizona graduate student Stephanie Sallum and Stanford University postdoctoral researcher Kate Follette, focused high-powered telescopes at LkCa 15 and near the star, the Washington Post said. It's known that baby planets give off this glow as hydrogen gas falls toward the forming body in a very hot process that reaches a temperature of 17,500 degrees Fahrenheit, the report added.

Although it's extremely difficult to differentiate between light given off by a planet and light given off by a star in a solar system so far away, it was the red glow that allowed them to make this discovery, Follette said in a statement.

"The reason we selected this system is because it’s built around a very young star that has material left over from the star-formation process," Follette added. "It’s like a big doughnut. This system is special because it’s one of a handful of disks that has a solar-system size gap in it. And one of the ways to create that gap is to have planets forming in there."

Prior to this discovery, there have been nearly 1,900 mature exoplanets discovered across our universe, the L.A. Times also said. It's likely that these two or three baby planets are gas giants, Space.com added.
