What magnetic fields can tell us about life on other planets?
Earth has a magnetic field – it’s what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and...
Finding the happy medium of black holes
Using data from NASA's Chandra X-ray Observatory and other telescopes, scientists have taken major steps in their hunt to find black holes. Through this...
Astronomers spot a distant and lonely Neutron star

![This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.
