A view of HOPS-315, a baby star some 1,400 light-years from Earth where astronomers have observed evidence for the earliest stages of planet formation. Combined with data from the James Webb Space ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

Most of our knowledge about the Solar System’s formation and evolution comes from the study of extraterrestrial rock samples called chondritic meteorites. These rocks, which are fragments of asteroids ...

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

Scientists were able to see the moment when planets began to form around a star. Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of ...

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

When scientists want to understand the earliest history of our Solar System, they’ve typically turned to ancient meteorites. These celestial objects that come to Earth are remnants of the building ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.
