    • Is E.T. phoning us from Proxima Centauri? The answer to weird signals happening in the universe is never aliens, until maybe it is. Earlier this month, researchers announced that they had captured a very mysterious beam of energy in the radio part of the electromagnetic spectrum at 980 megahertz, coming from the closest star to our own.
    • Alien bacteria might live in the clouds of Venus. Astrobiologists were a-twitter with anticipation and skepticism in September when news broke of potential evidence of life in the upper clouds of Venus.
    • 'Oumuamua could still be an alien artifact. Two years ago, scientists spotted a cigar-shaped object hurtling through the solar system. Dubbed 'Oumuamua, the entity is considered by most to be an interstellar comet flung out from around another star.
    • Navy declassifies UFO videos but don't believe the hype. A fair number of Earthlings don't care what ambiguous evidence scientists come up with to show that aliens are out there.

    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 ...

  2. Oct 28, 2023 · Seager believes we'd confirm the existence of alien life only with sample-return missions — collecting samples from another planet or moon and bringing them back to Earth for study, in-situ...

  3. May 20, 2022 · Until there is much more – and much, much better – evidence, let’s conclude aliens haven’t visited yet. I can’t lie though, I’m hoping I’ll see a time when that evidence exists.

  4. Aug 28, 2019 · Next-generation telescopes and new ways of detecting life on other planets are transforming the search for extraterrestrials. We may finally be about to find out if aliens exist. By Sarah...

  5. Oct 25, 2023 · But alien civilisations with more advanced telescopes might already be able to spot us. "It's totally feasible that there's alien astronomers that have built a 100m (330ft) space telescope that ...
