Traces of Organic Molecules Have Been Located on Ceres – Futurism

In Brief

As scientists ask everyone to help them locate the elusive Planet Nine, researchers involved inNASAs Dawn mission are hard at work studyingthe dwarf planet Ceres. The Dawn mission has previously uncovered evidence of water, ice volcanoes, and carbonate minerals that cause the mysterious bright spots on Ceres surface. Now, researchers have found traces of organic molecules on Ceres using Dawns spectrometer to map the dwarf planets surface in visible and infrared wavelengths.

What weve found on Ceres is probably the most unambiguous detection of organics on any Solar System body other than Earth, said Carl Pieters, Dawn mission investigator, in an interview with Brown University. Weve collected meteorites on Earth with organic signatures, which makes us think their parent asteroids may have had organics. But until now we havent seen such definitive evidence on any asteroid. So this could help us put together the history of organics in the Solar System.

There are high-resolution data available from Dawn that provide the geologic context for these deposits, added Pieters. Were looking at those data now, which will help us to pin down the origin of these materials. The discovery was found in a crater-ridden region called Ernutet in the northern part of Ceres, and the teams findings were published in the journal Science.

Organic molecules, such as carbohydrates, nucleic acids, and proteins, are the basic building blocks of life. Organic materials have previously been found in meteorites and on Mars, and whilefinding these on Ceres doesnt mean that theres life on the dwarf planet, coupled with the discovery of water and carbonate minerals, they do indicate that Ceres is potentially ripe for life.

Its kind of like baking a cake, Pieters explained. You can have all the ingredients, but if you dont put them together properly, you dont end up with a cake. So there is still plenty of work to be done before we can start thinking about whether microbes were able to form on Ceres.

While the discovery doesnt directly translate to discovering extraterrestrial life, it definitely improves the chances of finding it. The fact that these ingredients of life are located in a single setting outside of Earth is a great first step.
