Extraterrestrial

Venus may be a hellscape, but there’s a chance some forms of life could evolve there. A new MIT study has now found that the building blocks of life are surprisingly stable in highly concentrated sulfuric acid – which Venus’ clouds are made of.

We might find alien life as soon as 2030, suggests a new study. A lab experiment has shown instruments on a spacecraft headed to one of the most promising worlds to find life are sensitive enough to detect a single living cell in a single ice grain.

UFOs are having a renaissance lately, moving beyond the tinfoil-hatted crowd and into the realm of serious government investigation. Now a study has analyzed the geography of almost 100,000 sightings and found a few clues about how they cluster.

Look at the development of Earth-bound tech and you'll find fire at the heart of it, says a duo of researchers. And what does fire need to burn? Oxygen, whose chemical signature could provide clues to technological societies on worlds beyond our own.

Researchers from MIT and the University of Birmingham (UB) believe that they've cracked the formula for detecting habitable planets using currently available technology. It all has to do with an exoplanet's levels of carbon dioxide and ozone.

From where “love” is felt in the body, to the scientific value of giant piles of bird poop, and talking to whales as practice for understanding aliens, here are the top 10 weirdest science stories of 2023.

Meeting aliens rarely goes well for humanity in movies. Scientists have been practicing by trying to chat to whales in their own language – and judging by early results, we should probably beef up security around the Eiffel Tower and the White House.

Phosphorus – a key ingredient for life as we know it – was thought to be relatively rare in space. But now, astronomers have detected a surprising amount of the stuff on the fringes of the galaxy, suggesting life may be more common in the cosmos.

The best places to search for life beyond Earth aren’t planets like Mars – they’re icy moons like Europa. The case for life on this watery world just got stronger, as the James Webb Space Telescope has detected a fresh carbon source there.

Researchers have developed a new technique to better detect extraterrestrial radio signals by weeding out the interference caused by Earth-based devices. It’s hoped that the technique will lead to the first evidence of alien life.

A new discovery has boosted the chances of life soon being found on another world. NASA has announced the detection of phosphorus, the rarest element that’s essential to life, in the oceans of Saturn’s moon Enceladus.

A new study suggests that if any alien civilizations are turning their radio telescopes toward Earth, they may be able to not only detect our mobile phone signals, but could deduce a lot about our planet and even produce crude maps of it.
