Simulation suggests up to 24 Earth-mass worlds could share an orbit, just like two of Saturn's moons. Finding such an arrangement could point to advanced aliens.

The design of advanced synchrotron radiation sources requires precise algorithms for the simulation of electron trajectories in complex magnetic fields. However, multi-parameter studies can be ...

Using the Systems Tool Kit simulation software, the authors examined various LNCSS constellation case studies based in elliptical lunar frozen orbit and with a low-grade chip-scale atomic clock.

Delivered via a secure, high-power signal from Xona’s low Earth orbit satellites, the patent-pending Pulsar™ service aims to enable the next wave of connected technology.

An asteriod has been caught in Earth's orbit for a while and astronomers think it might be a mini-moon.
