NASA detecta maior molécula existente no espaço

NASA detecta maior molécula existente no espaço

"O Telescópio Espacial Spitzer, da NASA, descobriu no espaço, pela primeira vez, moléculas de carbono conhecidas como "buckyballs".
As bolas de carbono foram localizadas em uma nebulosa planetária chamada Tc 1. Nebulosas planetárias são restos de estrelas como o Sol, que expelem suas camadas exteriores de gás e poeira à medida que envelhecem."

Solar Eclipse

A total solar eclipse arced across the southern Pacific Ocean Sunday, blotting out the sun and offering stunning views to skywatchers, some of whom ventured to remote islands or rode cruise ships just to see the event. in

As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially covers the Sun as viewed from a location on Earth. This can only happen during a new moon, when the Sun and Moon are in conjunction as seen from Earth. font wikipedia
