If there is a place to look for traces of alien civilization, the solar system is a more feasible choice than some distant star systems. The cosmic bodies within the Sun family are also ideal for hiding artifacts from eons ago, only that humans have to look hard enough for them.
NASA's Cassini spacecraft found the trace of hydrogen on the icy moon of Saturn named, Enceladus. Southwest Research Institute (SwRI) scientists are assuming there must be several hydrothermal vents beneath the surface that can sustain life.
Researchers have discovered traces of organic material at 10 km below the seafloor in the Mariana Trench. This Organic material is similar to what is produced by microbes living in more accessible places.
From the moment they were discovered by NASA's Dawn spacecraft, the two bright spots on Ceres have fascinated scientists and amateur astronomers across the world. What are they and why are they there? Scientists believed that once Dawn reached orbit they would be able to learn more about these two mysterious spots, but even now they remain a mystery. NASA has made an unusual move by inviting the public to weigh in on what they believe is the nature of these two bright spots.
