A building heat wave in Portugal and Spain threatens to topple national and all-time high temperature records in a continuation of a series of remarkable heat waves that have roasted the Northern Hemisphere this summer.
The big picture: The heat wave will be most intense in Portugal, Spain and parts of France, although the U.K. will also see above average temperatures for this time of year. In Spain and Portugal, the fire danger will climb to dangerous levels as temperatures soar, humidity levels plunge, and downslope winds increase.
A team of U.K.-based scientists have identified a group of planets outside our solar system that have similar chemical conditions that likely led to the formation of life on Earth.
The big picture: The scientists found a collection of planets with the potential to host water that also have stars positioned to potentially provide ideal conditions of both light and temperature that could set off the necessary chemical reactions to form life.
