Are we really aliens out there, or are we all alone in the universe? Unsurprisingly, scientists think about it too. Now, a new survey published in Nature Astronomy analyzed what researchers believe.

A new interpretation of the famous Drake equation finds little reason to be optimistic about the search for extraterrestrial intelligence.

And that without the capacity to tolerate life's partial or total meaninglessness, we become perilously susceptible to ...

Only a small fraction of our galaxy has been studied and the question of whether aliens exist is something scientists have been trying to understand, explore and figure out for a long time.

Aliens can only see what we’ve built after we’ve already built it, and it takes time for those light signals from our constructions to make their way out into the cosmos.

Even if superintelligent aliens exist, we’re far likelier to detect their technosignatures, such as radio waves, than to actually meet them, ...

When we turn to “complex” extraterrestrial life or “intelligent” aliens, our results were 67.4% agreement, and 58.2% agreement, respectively for astrobiologists and other scientists. So, scientists ...

We’ve still not found aliens, even though a majority of the scientific community, as well as the general public, believe they exist. Mind you, radio waves from the cosmos are commonplace, ...

This image provided by NASA shows a top-down view of the OSIRIS-REx Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head with the lid removed, revealing the remainder of the asteroid sample inside.

The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start. “That’s the ...

The problem facing SETI scientists is that, based on observations so far, F probably is not near 1; otherwise, we would have noticed by now that we are not alone, assuming that intelligent aliens ...
