Astrobiologists Create Framework to Study Extraterrestrial Life Evolution
Astrobiologists are redefining the search for extraterrestrial life, focusing on evolution and complexity in physical systems. Methods include spectroscopy for detecting chemical signatures and frameworks exploring non-Earth biochemistry. Researchers are also investigating technosignatures and minerals linked to biological processes. A universal un...

NASA’s Viking Mission May Have Destroyed Martian Life with Water Experiments
In 1975, NASA’s Viking mission tested Martian soil for microbial life using liquid water. A recent theory suggests this approach may have destroyed microbes adapted to Mars' dry, salt-driven conditions. Astrobiologist Dirk Schulze-Makuch proposes revisiting our assumptions about life on Mars and prioritising methods suited to its hyperarid enviro...

In Pics: This Is What Freezing Antarctica Weather Does To Food
French astrobiologist Cyprien Verseux was conducting research in Antarctica when the temperatures dipped to as low as -60 degrees Celsius. In conditions like that, he decided to check how the food we eat every day behaves in such low temperatures.

Heinz Collaborates With Astrobiologists to Produce Ketchup From Tomatoes Grown in Simulated 'Martian' Soil
Heinz has produced a ketchup that is becoming popular for more than just its flavour. A team of 14 astrobiologists worked for months to achieve a similar feat — but on Earth. They worked at the Aldrin Space Institute at the Florida Institute of Technology to grow these tomatoes in a controlled environment with soil, temperature, and water conditi...

Did Mars Ever Look Like Earth? NASA Scientist Answers
Mars is quite similar to Earth, as per a NASA scientist. In a video interview, astrobiologoist Dr. Becky McCauley Rench said that the Red Planet wasn't as dry always, as we see it today. As per NASA's own website, “Mars, like Earth, has seasons, polar ice caps, volcanoes, canyons, and weather.”

Interstellar Gatecrasher 2I/Borisov Is No Ordinary Comet
"This shows that 2I/Borisov is not a completely alien object, and confirms some similarity with our 'normal' comets, so the processes that shaped it are comparable to the way our own comets formed," said Martin Cordiner, an astrobiologist working at NASA's Goddard Space Flight Center.

This Mysterious Space Signal Is (Probably) Not From Aliens
The signal was like nothing Abel Mendez had ever seen. It had the same frequency as radio emissions from satellites, but it pulsed like it came from something much more distant. It appeared only when Mendez and his colleagues had their telescope pointed at a single star - an unassuming red dwarf called Ross 128 just 11 light-years away.

Why No Alien Is Calling US From Space
If the search for an alien life has not yielded any conclusive results in the last 50 years, it is probably because life on other planets was brief and has gone extinct soon after its origin owing to runaway heating or cooling on their planets, say astrobiologists led by an Indian-origin scientist.

How Filthy is the International Space Station? An Astrobiologist Weighs In.
Earlier this year, astronaut Scott Kelly described the International Space Station's singular aroma as something akin to a mixture of antiseptic and garbage. There's no positive way to spin that one. But how clean (or dirty) is the International Space Station?

It's a bug's life: microbes to inherit the Earth
A study by astrobiologist Jack O'Malley-James of the University of St Andrews, Edinburgh, said that two billion years from now, an ever-hotter Sun will have cooked the Earth, leaving microbes confined to pockets of water in mountains or caves as the last survivors.
