Scientists from the University of Leeds have discovered enough water vapour to fill Earth’s oceans more than 2000 times over in a gas and dust cloud which is about to collapse into a Sun-like star.
Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun stirred up the magnetic field around Earth and produced gorgeous displays of northern lights.
A new study reveals that a significant amount of carbon released into the atmosphere from lakes and rivers in Southern Québec, Canada, is very old – approximately 1,000 to 3,000 years old – challenging the current models of long-term carbon storage in lakes and rivers.
A team of paleontologists and engineers has found that duck-billed dinosaurs had an amazing capacity to chew tough and abrasive plants with grinding teeth more complex than those of cows, horses, and other well-known modern grazers.
