A team of international scientists found that some types of bacteria can withstand the extreme chemical hazards of antifreeze.
And the team believe this discovery could be a sign of life on Mars.
Researchers from the UK, US and Germany claim incredibly briny oceans of liquid water could be locked away on Mars, Pluto and the moons orbiting Saturn and Jupiter.
The salty concentrations keep liquid oceans far from the sun from freezing over but also make conditions for life extremely hazardous.
But a little critter dubbed Planococcus halocryophilus has shown an incredible resilience to the otherwise deadly conditions.
Researchers submitted the bacteria to baths of sodium, magnesium, calcium chloride and a chemical known as perchlorate.
Perchlorate is a toxic chemical that is abundant in Martian soil and which drastically lowers the freezing point of water.
In large concentrations perchlorate is extremely toxic to bacteria but diluted concentrations of the chemical can actually help some microbes thrive.
