New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building ...

This artist’s concept depicts one of the solar system’s inner planets slamming into Earth after being nudged on a collision course by a passing star. Such a world-shattering cataclysm is extremely ...

A fascinating glimpse into how a solar system like our own is born has been revealed with the detection of planet-forming "pebbles" around two young stars. Subscribe to our newsletter for the latest ...

Astronomers across the globe constantly monitor space for glimpses of new objects beyond the solar system. In fact, NASA is tracking a rare planet unlike anything in our solar system — Enaiposha (GJ ...

All of our solar system’s planets are lining up in the night sky at once this week. This extraordinary celestial event will see the sky scattered with seven visible planets in what is known as a great ...

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 ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course. When ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...
