Following NASA’s latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
Using AI to search for ET might help us find things we couldn’t even imagine we should look for, but to succeed we also have think critically about how we create and use that technology.
Planetary protection protocols try to make sure we don’t seed places like Mars with life from our planet. An astrobiologist argues they’re misguided – especially with human astronauts on the horizon.
There has been much excitement this week about the possibility of water – and life – on some newly discovered exoplanets. But we can look closer to home for evidence of ET.
We continue to search for intelligent life elsewhere in the universe. But if we find ET there are those who question whether we should make contact or not.
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people’s imagination?
There are technological ways to hide a planet from intergalactic detection – as well as ways to signal that we’re just sitting here, eager for contact.
It’s an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today’s technology or even technology in the near future?
A US$100-million plan has been announced to send tiny probes out in space in search of life elsewhere in the universe. But are they looking in the right place?
