“Meeting an advanced civilization could be like Native Americans encountering Columbus,” he said.
If there are any, aliens should be less conspicuous and charismatic-looking than most people think.
When the very large can’t be found, maybe it’s time to look for the very small.
Natural selection fosters certain qualities so aliens shouldn’t look extremely different from humans.
The mysterious high-energy signals are unaccounted for. Alien technology is not excluded.
It may be possible to observe the presence of an advanced alien civilization by the effects produced if that civilization were to self-destruct through nuclear war, biological warfare, nanotechnological annihilation, or stellar pollution. Each case would generate unique detectable signs that could be identified by earth-based telescopes.
Where are all the aliens? Why haven’t we seen or heard their signals from space? Could we really have been the only planet where life evolved?
If you’re an alien buff or just really, really bored with knowing just one species that can hold a decent conversation, this might come as a bummer. SETI has confirmed that KIC 8462852, the 1,500 light-years away star that’s been all over the news as potentially having signs of an advanced alien megastructure built around it is just a regular, run of the mill, alien-free ball of atomic fire.
This week space fanatics were teeming with excitement after it was announced that Stephen Hawking had teamed up with Russian billionaire Yuri Milner in a quest to find extraterrestrial life.
This past week, a few scientists took the bench and gave the U.S. Congress a relative date by which they expect we’ll have discovered signs of intelligent life elsewhere in the universe. According to their estimates, by 2034 we should make first contact or 30 years ahead of Star Trek’s first contact. Whether this was just a stunt, a ploy
One of the most outstanding dreams astronomers and other scientists hope to accomplish is to someday encounter proof that extraterestrial life exists. Intelligent life might be extremely far off, however microbiological life should without a doubt be present elsewhere other than our planet or solar system. For life to blossom, however, the right conditions have to be met, and one
Crop circles have always been an important weapon in any conspiracy theorist’s arsenal, certain to be mentioned alongside UFOs, green aliens or reptilians. Since 1970, tens of thousands of crop circles have been reported around the world, most amateur hoaxes, while some are so intricately built that they even baffle scientists. In this month’s edition of Physics World, Richard Taylor,
In a surprising move that didn’t get quite a lot of attention, the FBI released an online document archive they’re calling the Vault, in which they openly address, among other things, the alleged aliens and flying saucers found at Roswell. Yes, it’s about little green men, like the ones who are usually portrayed in movies. The memo at the core
Two days ago, the whole world was teeming with excitement, after some NASA researchers reported finding traces of alien life in meteorites; now, even their employer distances itself from them, and the whole scientific world seems to frown upon this work. However, in what is a very unusual move, NASA has denied any involvement with the paper, and even the
In case you didn’t know the United Nations has appointed an ambassador for our little planet, in case aliens somehow contact us in the near future. Who was chosen for this position that could be crucial in the highly unlikely event of a discussion with aliens ? Mazlan Othman, head of the Office for Outer Space Affairs. The Malaysian astrophysicist
It was Thursday night when locals from Norway started to notice a strange, rotating light that just baffled them. It was visible long enough to be seen, photographed and recorded by half of country. The blue light seemed to appear from behind the top of a mountain; it rose, began to spin, then began to circulate. Naturally, as it became
