Sep 10, 2021 · Do aliens exist? Extraterrestrial life has never been discovered, but that doesn’t mean it doesn’t exist. At NASA, astrobiologists like Lindsay Hays are trying to answer one of the most profound questions ever: Is there life beyond Earth?
- UFO 'turning point' Following an upswing in sightings of UAPs in 2021, experts told Space.com in January 2022 that the next 12 months could be important for the investigation of such mysterious objects.
- Declassified UFO reports. A popular theme among UFO enthusiasts is how much various governmental agencies know about these mysterious objects and their possible origins.
- Another Fermi paradox proposal. Where are all the aliens? In May 2022, two scientists proposed a disturbing solution to the so-called Fermi paradox: Maybe a civilization intelligent enough to develop space travel would eventually develop to a point where their energy demands would outpace innovation, resulting in the collapse of that civilization.
- A climate alert to aliens. In May, researchers aimed to send a message to notify aliens of Earth's climate crisis and possibly request aid. The message was devised by a group called Messaging Extraterrestrial Intelligence (METI) International, which wants to send a message encoded within a radio signal to the TRAPPIST-1 planetary system, which hosts at least seven Earth-like planets.

I think that has to be a definite yes. But I think the real question is, are aliens close enough for us to discover them? Space is unbelievably big. In the last few decades, we've learned almost every star in the cosmos has planets. Our galaxy, the Milky Way, is estimated to have up to 400 billion stars. If each of those has five planets, we'd have...
Yes, but that's a bold assertion. So, let's be clear what we are talking about. I consider the term "alien" to reference all manner of life, as we understand it on Earth, resident in places other than on Earth. Having said that, there is currently no detailed consensus on the definition of "life". It is a very complex concept. But if we found somet...
I'm of the opinion that it's only a matter of time before we find something that resembles biology somewhere other than on Earth. This is because we're increasingly finding various potential pockets in our solar system that may be hospitable to life as we know it. For instance, consider the under-ice oceans of Europa and Ganymede (two of Jupiter's ...
Yes, but they probably don't look like us. There are more than 100 billion planets estimated to exist in our galaxy alone (with some six billion potentially being Earth-like). Therefore, the probability that life exists elsewhere is all but confirmed. When we hear the word "alien", however, an image of a humanoid lifeform usually springs to mind. B...
A simple answer to this question is no. If we use purely empirical data and assume the question refers to any type of life outside of Earth that is not related to human activity, then the answer – as far as we know – must be no. But, of course, our knowledge relating to this question is finite; we have not investigated every corner of the Universe ...
Jun 7, 2023 · Lots of people believe in aliens, although this belief tends to be based on movies and UFO claims. But science provides insights for the likelihood that we’re not alone in the Universe, and can answer some of the biggest questions people might have about what kind of life is most likely to actually be out there.
Apr 8, 2023 · Are aliens real? While there is no current evidence for extraterrestrial life anywhere in the universe, scientists are still optimistic.
Jun 13, 2021 · Even if aliens exist, are intelligent like humans and interested in making contact with us, what are the chances they’ll be close enough for us to hear them screaming their presence into...
