Ceres: Evidence Suggests Past Microbial Life in Solar System
Scientists think there might have been life on a dwarf planet called Ceres a long time ago.
They found evidence of saltwater and stuff that microbes could have eaten.
Around 2.5 to 4 billion years ago, the inside of Ceres got warm because of radioactivity, like a hot tub for tiny life forms.
This is similar to what happened on early Earth.
Ceres has salt on its surface, which means there was once water there.
Simulations show that the hot water may have created vents similar to those that sustain life on Earth.
NASA found evidence of potential microbial life on dwarf planet Ceres.
Ceres may have had saltwater lakes and organic carbon, similar to Earth's early oceans.
Radioactivity within Ceres could have created warm water conditions conducive to microbes.
Salt discovered on Ceres' surface indicates the presence of a saltwater source.
Simulations suggest hot water vents on Ceres might have supported chemotroph microbes.
