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?

- UFOs are real (and the government knows it) In June, the Pentagon released a highly anticipated report detailing 144 UFO encounters between 2004 and 2021.
- Black holes could be alien powerhouses. While alien hunters spend plenty of time searching for habitable planets beyond our solar system, a study published in July in the journal Monthly Notices of the Royal Astronomical Society warns that scientists shouldn't overlook nature's most extreme objects: Black holes.
- Alien planets may look nothing like Earth. Typically, the search for alien life begins with the search for Earth-like planets — but there may be another class of alien world that is just as conducive to life, a study published in the Astrophysical Journal in August contends.
- One of Saturn's moon still holds potential for life. The methane wafting from Enceladus, Saturn's sixth largest moon, may be a sign that life teems in the moon's subsurface sea, a June study found.

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 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 the...
Nov 25, 2023 · Aliens are having a moment. But the evidence says all possibilities remain in play, including the possibility that we are alone.
Alien astronomers might be looking in our direction from distant planets. What would they see? We've been searching the heavens for some time now. But despite decades of listening for tell-tale...
