Could the first confirmed signal from an extraterrestrial source be less a hello than a goodbye? Astrophysicist David Kipping ...

For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are ...

Scientists suggest the first alien signal we detect could be a desperate cry for help from a fading civilization.

In this scenario, our first contact with aliens would be tragic. We should look for "loud shouts in the night".

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 ...

Interstellar objects such as Comet 3I/ATLAS can be sent by alien civilizations to "sow" life on Earth. At the same time, it is almost impossible that for the entire time of Earth's existence the Earth ...

Aliens might be transmitting communications signals to each other across exoplanets, some astronomers think. Since these signals are likely sent as narrowband radio waves, we may now have a way to ...

A new study published in the journal Astrophysical has outlined a novel method that could be used to detect advanced alien civilizations remotely. The premise is to look for signs of nuclear fusion on ...

If the technological capacities of intelligent entities throughout the cosmos are unbounded, why haven't we seen signs of other intelligent life? When you purchase through links on our site, we may ...

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 ...

James has been gaming for as long as he can remember, from conquering the world in Civilization or blowing up worlds in Stellaris to getting sucked into yet another grind on either version of ...

Astrophysicists estimate that any exponentially growing technological civilization has only 1,000 years until its planet will be too hot to support life. When you purchase through links on our site, ...
