For thousands of years, Nile fertilized valleys along its meandering path through northeast Africa. It anchors ancient civilizations and still serves today as an important transport and irrigation route. However, the age of its venerable waters spanning 4,225 miles (6,800 kilometers) has been debated, with one group of experts claiming that the river was created about 6 million years ago, …

In a deserted mine in southern Spain, there is a room of pure crystal. To get there, you have to descend deep into tunnels, climb a ladder into an unobtrusive hole in the rocks and squeeze yourself through a jagged tube of gypsum crystals barely wide enough for a person. If you make it this far, you'll be in the …

Pedro Amado / Marco Azzaro – IAA / CSIC One of the difficulties in studying our Earth and the solar system in which it is located is that you generally work with a sample size of one. Astronomy, however, increasingly loosens this limitation with ever clearer …

The birthplace of two meteorites from Mars appeared to be a two-crater zone: new insights that scientists use to uncover secrets on the Red Planet. Perhaps the older of these two craters formed during an impact that burst boiling water and interacted with minerals. All in all, the picture the researchers put together using a rare class of meteorites could …

21st August 2019 While Chantal is monitoring several other areas in the Atlantic Basin, explosive tropical development this week is unlikely. On Tuesday night, a low-pressure area more than 450 miles southeast of Halifax, Nova Scotia, became Tropical Storm Chantal. Chantal will feel this week in the east and then in the southeast across the open North Atlantic. The storm …

Einstein's Theory of General Theory of Relativity has proven itself time and again and is generally regarded as a solid foundation for the understanding of the universe. However, it is not the only model to explain the operation of gravity and the formation of galaxies – and new research has shown another model under which the Milky Way could have …

The influence of Chicxulub is known to have killed the dinosaurs and most other species living on Earth at that time, leaving behind a thin layer of dust rich in rare elements. Modeling the impact has suggested almost too many ways in which it could have killed: massive tsunamis, a …
