Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
Scientists working with data sent back by the now-slumbering Philae lander have announced the discovery of organic molecules on the comet 67P/Churyumov-Gerasimenko. Finding organic compounds on 67P’s surface…
The drama of Philae’s slow fall, bounce and unfortunate slide into hibernation was one of the most thrilling science stories of a generation. But what in its short 60 hours of life on Comet 67P did it…
Theoretical physicists are caricatured in the popular imagination as only involved in abstruse and difficult-to-imagine topics. But some of these theoretical physicists are involved in something closer…
Scientists have simulated the electrical energy produced in the Earth that may have led to life 3.5 billion years ago. Using a fuel cell, researchers from the University of Leeds and NASA’s Jet Propulsion…
How life came about from inanimate sets of chemicals is still a mystery. While we may never be certain which chemicals existed on prebiotic Earth, we can study the biomolecules we have today to give us…
No one knows how life began on Earth. But for it to happen, some simple chemical building blocks would have been needed. Many scientists argue the Earth’s violent past, with its massive volcanoes and regular…
