The truth is out there—but identifying signs of life in space involves an intense search for biosignatures within our solar system and beyond. However, developing sensitive yet com...
There’s an active debate in the astrobiology community of where to use our best telescopes to look for our best chance of seeing alien life. That debate has been going on for decad...
Is there life elsewhere, or is Earth unique in the universe? This is one of humanity's great unanswered questions. One way to approach this mystery is to investigate how life began...
Microbes from space have fueled the plots of science fiction mainstays like "Project Hail Mary" and "The Andromeda Strain." But with more space missions launching each year, findin...
What are the chances of finding extraterrestrial life in our solar system? Frank Postberg, a professor of planetary science at Freie Universität Berlin, has published a study in Sc...
Conditions on early Earth may have become stable enough to sustain the chemistry associated with the origins of life around 4.33 billion years ago, according to new research co-led...
Even planets billions of years older than Earth may host only microbes if photosynthesis supplies too little energy. Science fiction often imagines Earth’s galactic neighborhood te...
In the search for extraterrestrial life, it makes sense to first look for rocky planets with an atmosphere, like Earth. Without an atmosphere, a planet can't have surface water. Bu...
Researchers at the National High Magnetic Field Laboratory and Brookhaven National Laboratory have teamed up to get a fresh look at the complex makeup of meteorites and glimpse int...
Scientists have known for a while that meteorites contain the “building blocks” of life - complex organic molecules such as amino acids, simple sugars, or even the chemical rungs o...
Two new studies suggest that Saturn’s moon Enceladus may be an even more compelling target in the search for extraterrestrial life. If scientists want to search an alien ocean for...
We've been searching for life on Mars for a long time, but so far we've come up empty. The fundamental problem is a Catch-22 involving two of the key ingredients for life. Life as...
Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a ch...
Billions of years ago, rain may have helped shape where the chemistry of life could begin on Mars. A new study maps how formaldehyde, an important prebiotic molecule, may have reac...
Microbes carried to space by human explorers could survive in shaded areas near the moon’s south pole, according to researchers from NASA and the University of Maryland. Even on th...
By simulating a billion years of Earth’s history, researchers have identified a possible window for life’s earliest chemistry around 4.33 billion years ago. During its first few hu...
Planetary scientists from Freie Universität Berlin have published two new studies that indicate that a spacecraft could identify evidence of life much more easily than previously t...
New research led by the University of Michigan is helping set the stage for future observatories to characterize rocky planets outside our solar system, planets that could prove li...
Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans...
Great news, everyone! New evidence points towards complex life being very robust. The post I Am No Longer Pessimistic About the Survival of Complex Life on Earth, Thanks to Science...
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mou...
Experiment suggests organisms could live in harsh environment under Enceladus’s icy crust, strengthening possibility moon could support lifeFrom the moment scientists spotted plume...
We’ve been searching for life on Mars for a long time now, but so far we’ve come up empty. The fundamental problem is a Catch-22 of two of the key ingredients for life. Life as we...
The Mars we know today is a cold, dry world of dust and rocks. However, around 3.8–3.6 billion years ago, it may have looked very different. Geological and mineral evidence suggest...
