With a diameter of 88,846 miles at its equator, Jupiter is the biggest planet in our solar system. It’s eleven times larger than Earth, so big in fact that its gravitational forces are thought to be ...

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

The birth of a new solar system may have been caught on camera. About 1,400 light-years from Earth sits a young sunlike star surrounded by cooling gas and teensy silicate minerals. These mineral ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Asteroids, the enduring remnants of early Solar System formation, offer invaluable insights into the processes that shaped planetary evolution. Their diverse orbits, sizes and compositions not only ...

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.
