Ever since Isaac Newton famously talked about gravity, its dominance as a force in our Solar System has been well known. It’s responsible for the orbits of the planets and their satellites but there ...

The solar system does not end neatly at Neptune’s orbit. This episode reveals the vast, invisible structure of icy debris beyond the known planets, shaped by gravity and time. From scattered objects ...

Approximately 4.5 billion years ago, a cold cloud of gas and dust buried deep in one of the Milky Way galaxy’s spiral arms started to collapse. From there, gravity worked its magic. The cloud began to ...

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity ...

NASA's infrared telescope SPHEREx captured stunning images of interstellar comet 3I/ATLAS as it exited the solar system.

Gravity is the force that governs the structure and motion of the solar system, keeping celestial bodies together in a cosmic dance. The sun, with its immense mass, generates the strongest ...
