Earth's new Trojan asteroid orbits Lagrange point 4 (L4) in an elliptical orbit that flings it nearer to the sun than Venus and about as far away as Mars.

Researchers show that planetary alignments make Earth’s strongest space signals easiest for alien civilizations to detect.

The search for extraterrestrial intelligence (SETI) has been ongoing since the 1960s, yet no confirmed signals from alien ...

In a new study, researchers at Penn State and NASA’s Jet Propulsion Laboratory analyzed when and where human deep space ...

A new study reveals how Earth's strongest radio signals, meant for our own spacecraft, "leak" into the cosmos in predictable ...

"Considering the direction and frequency of our most common signals gives insights into where we should be looking to improve ...

The United States military could secure the Earth-moon Lagrange Points — areas where the gravities of the Earth and moon cancel out — against the Chinese..

Normally, the far side of the sun remains hidden from us and our space telescopes, which are positioned in orbit around Earth or at our planet's Lagrange points, where objects can be permanently ...

This graphic shows where the Earth Trojan asteroid 2020 XL5 would appear in the sky from Cerro Pachón in Chile (site of the SOAR telescope) as the asteroid orbits the L4 Lagrangian point.

The Lagrangian equilibrium stability points are places where the gravitational forces of two bodies produce regions of gravitational balance.
