‘Extremophile’ bacteria can survive extreme cold, heat, acidity and pressure.
Only 10.2% of astrobiologists disagree with the claim that intelligent aliens likely exist.
A specific set of chemical conditions led to the emergence of life on Earth. But can life emerge from other chemistries?
On what would’ve been the astronomer’s 90th trip around the Sun, here’s a look at his legacy as a scientist, advocate and communicator.
On October 10, Europa Clipper will take off on a long journey to Jupiter’s moon Europa. The icy moon could potentially host alien life – and there’s only one way to find out.
AI may be destroying civilisations before they get a chance to explore space properly.
It’s not easy to collect rocks on a budget when the rocks are 140 million miles away.
Saturn’s moon Enceladus has geysers shooting tiny grains of ice into space. These grains could hold traces of life − but researchers need the right tools to tell.
When scientists observed planets revolved around the Sun, they posited we were now like other planets. And if other planets were like Earth, then they most likely also had inhabitants.
Determining whether or not life exists on another planet is an extraordinarily complicated – and expensive – scientific endeavor.
While NASA rovers on the surface of Mars look for hints of life, researchers back on Earth are studying ‘echoes of life’ from ancient basins – hoping that the two sites might be similar.
Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.
Control experiments are critical in informing the search for alien life.
Modern reactions to unidentified aerial phenomena (UAPs – what you might think of as UFOs) are similar to those of thousands of years ago.
The space agency hopes to get to the bottom of the many sightings being reported.
Months after a military officer made sensational claims about unexplained objects in the skies, NASA released a report loosely outlining a scientific approach for analyzing UAP reports.
The results are intriguing, but analysing the atmospheres of exoplanets is no easy task.
Alien hunters should learn from the Intergovernmental Panel on Climate Change (IPCC).
Whistleblower allegations that the government possesses UFOs may not be backed up by public physical evidence, but some argue that listening for extraterrestrial life is the first phase of contact.
