Dyson sphere stability — once considered an impossible physics problem — may be within reach. A peer-reviewed paper in ...

Scientists may have discovered how extraterrestrial civilizations could actually detect and find Earth.

The Search for Extraterrestrial Intelligence (SETI) is a dream of humanity, but advanced extraterrestrial civilizations do not necessarily communicate in the same way as humans. A paper published on ...

It may take less than 1,000 years for an advanced alien civilization to destroy its own planet with climate change, even if it relies solely on renewable energy, a new model suggests. When ...

Alien civilizations, cosmic signals, and megastructures drive this deep search for intelligent life beyond Earth. The video ...

Advanced alien civilizations may communicate via a series of flashing lights, similar to how fireflies do, a new paper hints. This would potentially make extraterrestrials much harder to spot if we ...

In context: Radio waves from distant galaxies are too faint to provide meaningful data for potential space observations. However, a sufficiently advanced alien civilization could harness energy in ...

In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in ...

Researchers are considering the fact that there might be already the presence of very developed aliens civilizations which are out of reach of the humans. This theory is based on an assumption. The ...

“There is a silence in the night sky that has bothered me for as long as I can remember.” That line, attributed to Richard Feynman, lands because it gets at a simple, stubborn feeling. The sky looks ...
