True to its promise, the European Space Agency’s EarthCARE satellite is now being used to calculate directly how clouds and aerosols influence Earth’s energy balance – the all-important balance that regulates our climate. In doing so, EarthCARE is poised to sharpen the accuracy of climate models, the very tools that guide global climate policy and action.
The Butterfly Nebula is one of those cosmic objects that demands our attention, and even our fascination. It's also known as NGC 6302 or the Bug Nebula, but whatever name we use, the stunning spectacle of ionized gases draws our human eyes in. In fact, Butterfly and its nebulae brethren may be more responsible for generating public enthusiasm in astronomy than any other type of object.
