Simply put, gravity makes the whole universe move in ways that may seem crazy at first, but once it is better understood, it is very orderly. Once you understand these factors wel ...

When people think about telescopes, they generally imagine those giant buildings perched on top of some mountain here on Earth, or some piece of hardware floating around in close Earth orbit. But ...

Satellites and instruments placed at Lagrange points remain in a stable position because the gravitational forces from the Earth and sun balance each other, requiring only minimal energy for ...

The James Webb Space Telescope has been traveling through space since its launch on December 25, 2021, and will soon face the next crucial step in its mission, performing an orbital burn to insert ...

The idea of balanced forces is a central concept of physics, and we see it everywhere, from tug-of-war battles to card houses to football games. Until forces become unbalanced, the flag at the rope’s ...

Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional ...

You often hear about Lagrangian points because they can be handy places to “park” a spacecraft where it doesn’t need much fuel to stay in the same position relative to Earth. If gravity were the only ...

NASA’s Carruthers mission will film Earth’s elusive exosphere to understand space weather, atmospheric escape, and planetary habitability. A NASA mission aims to photograph a feature of Earth that is ...

No. This is not a Lagrange Point in Angry Birds Space. It is important, though. Let me get this over with. Why is this not a Lagrange Point? Basically, a Lagrange point is where an object can appear ...
