For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark matter and dark energy could simply be the effect of the natural forces of the universe slowly weakening as it ages.
Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean. Some of these reactions could be part of chains that lead to even more complex, potentially biologically relevant molecules.
Published today in Nature Astronomy, this discovery further strengthens the case for a dedicated European Space Agency (ESA) mission to orbit and land on Enceladus.
As the study of the universe evolves and the data sets get larger and more complex, a new breakthrough means researchers can analyze huge data sets with just a laptop and a few hours.
