Interstellar object 3I/ATLAS is making its closest approach to Earth in just over a week from now, coming within 167 million miles.

A solar storm could knock out navigation and communications systems, caushing satellites to crash into each other.

A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 per cent of sun-like stars

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a nearby supernova (the massive explosion of a star near the end of its life) bathed it in cosmic rays containing the radioactive ingredients to make rocky,

TRAPPIST-1e, an Earth-sized world in the system’s habitable zone, is drawing scientific attention as researchers hunt for signs of an atmosphere—and potentially life-supporting conditions. Early James Webb observations hint at methane,

Okay, it's not quite that common an occurrence, but there are indeed a number of firms giving this a go. The latest to join the fold is Overview Energy, a Northern Virginia-based startup that's raised US$20 million to try transmitting solar power from satellites down to solar panels on Earth, enabling a 24/7 supply.
