The researchers ran simulations of radiolysis at work in key locations in the Solar System to figure out how much energy it could potentially produce. By their calculations, Saturn''s moon Enceladus is the
Unsatisfied with starlight and ion engines, humanity had decided to recreate a star''s fusion and power their cities and starships directly, as well as using it for propulsion.
A team of researchers from NASA wondered whether it would be possible, with existing technology, to find a civilization using large arrays of solar panels to supply its energy needs.
As space imaging detects changes in wavelengths, this would make the solar panels visible to scientists on Earth. However, the team quickly encountered a problem. They found that a
Harvesting solar energy in orbit and beaming it down to Earth is a decades-old idea. Now, a raft of companies say they could make it a reality.
While aliens would likely need an abundant energy source to advance their civilization, who''s to say what form that energy would take? The answer could lie beyond human understanding.
The new study assumes aliens would build solar panels out of silicon. That''s because it''s relatively abundant compared to other elements used in solar power, such as germanium, gallium or...
Somewhere in the galaxy, an advanced alien civilization might harness energy from its star. And NASA wants to know if it could detect this activity. The space agency has some powerful...

The researchers also assume that a hypothetical extraterrestrial civilization would rely exclusively on solar energy. However, if other sources of energy are used, such as nuclear fusion, it
If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it''s the cleanest, most accessible form of energy, at least here on Earth. Driven by...
