A relatively simple mixture of chemicals can produce some of the compounds needed to form RNA, UNSW scientists have shown.
New research published today in Nature Communications suggests the rovers’ current equipment might not actually be up to the task of finding evidence of life.
To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical processes.
How ancient microbes survived in a world without oxygen has been a mystery. Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration.
Considering what we know about the key ingredients for life's formation on Earth, here are three explanations for how this process may have occurred on our sister planet.
The discovery of phosphine in the acidic clouds of Venus can't be explained by any known chemical or geological processes.
As Perseverance prepares to launch for Mars, two UNSW PhD students look back on a field trip that gave Indigenous high school students a behind-the-scenes look at the rover’s upcoming mission.
Hot springs may have been the ‘spark’ that helped organic matter turn into life – these UNSW Sydney scientists have put this hypothesis to the test in New Zealand.
Scientists have used the same methods that will soon be used to search for evidence of life on Mars to look for evidence of the earliest forms of life on Earth at a location in South Australia.
Western Australia’s famous 3.5-billion-year-old stromatolites contain microbial remains of some of the earliest life on Earth, UNSW scientists have found.
