The astronomers observed hot minerals just beginning to solidify – the first specks of planet-forming material, the ...

Astronomers first identified these minerals using the now-three-year-old James Webb Space Telescope. To see where exactly the ...

Astronomers have discovered the earliest seeds of planets forming around HOPS-315, a baby star located 1,300 light-years away.

International astronomers have for the first time witnessed the birth of a planetary system beyond Earth's sun that could one day resemble our own.

“What we’ve been trying to do is find a baby version of our Solar System somewhere else,” Merel van’t Hoff, an astronomer at Purdue University in West Lafayette, Indiana, tells Nature’s Jenna Ahart.

This solar system is unique because all six planets move similar to a perfectly synchronized symphony, scientists said. In technical terms, it's known as resonance that's "precise, ...

There may be another world lurking between the orbital lines of our solar system. Astronomers in Japan have published their theory of an “Earth-like planet,” dubbed Planet Nine, that’s ...

Our Solar System is beautiful, mysterious, largely unknown… and accessible. In the next hundred years, we can send robotic craft, and even human hands, to many of those worlds.

Some smaller bodies in the outer solar system, such as the trans-Neptunian object Huya (310 miles [500km] in diameter), appear to be round and may also be in hydrostatic equilibrium.
