A new exoplanet has been discovered that is a lot like Earth.
Simple mathematics suggests that if there are aliens out there, they should have reached us by now. So is it really worthwhile trying to communicate with them?
The $100m project to search for aliens will help save observatories from closure and could lead to new astrophysical discoveries.
Astronomers have been looking for signs of intelligent life elsewhere in the universe for centuries. But the search has so far found nothing. So what makes this latest hunt so different?
As far as underwhelming headlines go: “No Alien Life Found on Comet” must rank very close to the top. An article with this title appeared in the Guardian on July 6 in response to a story claiming that…
Astronomers have found thousands of exoplanets and the hunt is on for life beyond Earth. Once biological neighbors are identified, our planet’s philosophies and religions will need to adapt.
The Conversation organised a public question-and-answer session on Reddit in which Seth Shostak, senior astronomer at the SETI Institute, explained why searching for intelligent life is so important and…
The Conversation organised a public question-and-answer session on Reddit in which David Waltham, reader in mathematical geology at Royal Holloway in London, explained what makes Earth so special and what…
Enrico Fermi, when asked about intelligent life on other planets, famously replied, “Where are they?” Any civilisation advanced enough to undertake interstellar travel would, he argued, in a brief period…
Given that we are unlikely to be visiting an exoplanet any time soon, astronomers have been contemplating whether it might be possible to detect indications of simple life – a biosignature – from a distance…
Last week, scientists announced the discovery of Kepler-186f, a planet 492 light years away in the Cygnus constellation. Kepler-186f is special because it marks the first planet almost exactly the same…
Sarah dreads falling asleep. Moments after she closes her eyes, her body becomes paralysed, and she is unable to move no matter how hard she tries. This has been going on almost every night for three weeks…
