Daily Mail: Earth’s northern latitudes have been experiencing spectacular aurorae because of a 1 August eruption on the Sun that emitted a cloud of electrically charged particles—a coronal mass ejection. The first solar flare in a long while that has been aimed directly at Earth, the “solar tsunami” was really the result of two simultaneous events from different locations on the Sun: a huge flare above a giant sunspot and an even larger eruption across the Sun’s surface. NASA’s Solar Dynamics Observatory, launched in February, captured some high-quality views of the solar event, and Earth-based photographers captured some beautiful views of the resulting aurora.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
