Medicine & TechnologySeveral research projects are attempting to use existing conditions on Mars to fuel future missions. Now, a team of researchers is experimenting on turning greenhouse gases to create rocket fuel on the Red Planet.
An international collaboration found the fossils of methane-cycling microbes from 3.42 billion years ago, providing new insights on the potential habitability, or ability to sustain life, of early Earth.
Recent reports of Mars methane detections have fascinated both scientists and non-scientists alike. On Earth, a substantial amount of methane is generated by bacteria that help most livestock digest plants.
In a deep part of the Black Sea, situated between Europe and Asia, the waters still respond to a climate change pattern prompted by the last Ice Age - a period which officially ended about 12,000 years ago.
NASA has calculated the distinct evidence that shows how humans are causing climate change. Specifically, it has calculated the specific driving forces of recent climate change through direct satellite observations.
