Sep 10, 2021 · NASA has sent five rovers and four landers to the surface of Mars. Additionally, orbiters have been outfitted with some amazing cameras to take pictures of the whole surface of the Red Planet. But we’ve only explored a tiny fraction of Mars. And that’s only one of the promising bodies to look for life in our solar system.
Sep 14, 2023 · Earlier this week, Live Science reported that NASA's James Webb Space Telescope could likely detect signs of extraterrestrial life on an Earth-like planet up to 50 light-years away. Now, a new ...

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 ...
Oct 28, 2023 · The sobering reality is that there isn't any yet. There's no scientific evidence for aliens in the declassified UFO videos, in mutilated cows whose injuries are blamed on extraterrestrial ...

Sep 29, 2023 · Thirty years ago, we had no evidence of planets orbiting other stars. Now more than 5,000 have been discovered, which astronomers and astrobiologists can study in unprecedented detail.
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 Rugheimer
