What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

Have you ever wondered why all the planets in our solar system orbit in the same plane? This fascinating characteristic of planetary orbits has intrigued astronomers for centuries. When we observe the ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets.

The James Webb Space Telescope has captured an exoplanet no one had seen before. This marks a turning point in space ...

In classical (or "Newtonian") mechanics, which describes the motion of macroscopic objects (i.e., things larger than an atom, such as planets), gravity is sometimes called a central force.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

No telescope has basked in the night sky quite like the enormous new Vera Rubin Observatory. Here's what it could reveal ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

If gravity reversed on the sun, McCluskey said he’d be scared because it is the only thing keeping the sun together. Nuclear fusion, inside the sun, pushes outward. Without gravity, the sun would ...

This discovery marks the first known case of a compact planetary system with such a noticeable tilt between close planet ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI ...
