We’ve spent ages learning about the people who think they’ve come from another planet, so you don’t have to.

With more than 5,000 known exoplanets, astronomers are shifting their focus from discovering additional distant worlds to identifying which are good candidates for further study.
To date, we have not heard from any aliens. Nor have we seen any – but here are the fascinating projects working to change that.
Can artificial intelligence transform the search for alien intelligence?
There may be ways to check if our universe is just simulated entertainment for an advanced, alien species.
The technology of an advanced alien civilization is likely to produce many signs that could be detected across the vastness of space. Two astronomers explain the search for technosignatures.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
Life on Earth has dramatically changed the chemistry of the planet. Astronomers will measure light that bounces off distant planets to look for similar clues that they host life.
Have astronomers finally found evidence of intelligent found life beyond Earth?
A professor of religion and science explains different views on immortality, from the religious perspective of President Jimmy Carter to the scientific, secular take of Carl Sagan.
We should not be surprised that some of the innumerable rocks on Mars have weird shapes, because many have been sand-blasted by wind erosion for billions of years.
What kind of evidence would we really need, before we could reasonably conclude alien contact had been made?
This year, two groups of astronomers plan to send messages containing information about humans and the location of Earth toward parts of space they think may be home to intelligent life.
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Perseverance and its helicopter sidekick, Ingenuity, have been on Mars for nearly nine months. The duo have taken rock samples, performed first flights and taken images of the delta in Jezero Crater.
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
The history of UFOs weaves together public fascination, government secrecy and cultural phenomena. Recent news and shifts in the government’s stance on UFOs are giving new life to the mystery.
Plus, what’s happening in Chad, three months after rebels killed the president, Idriss Déby.
A new nine-page report, requested by Congress, doesn’t say what the 144 UFO sightings from 2004 to 2021 are, but does say that the government wants to learn more.
Some UFO sightings appear to demonstrate ‘advanced technology’. The Pentagon has confirmed some threaten flight safety, and potentially national security.
