Often called Earth’s green lungs, tropical forests pull down massive amounts of carbon dioxide from the atmosphere, release oxygen and help regulate the global climate. While the threat of large-scale deforestation is well known, new findings reveal a surprising culprit – the clearance of small areas of forest accounts for more than half of net carbon losses across the Tropics.
In 1604, German astronomer Johannes Kepler spotted a new star in the sky that was so bright it could be seen during the daytime. The discovery, which Kepler described in his book *De Stella Nova*, caused quite a stir in the astronomical community. With this one point of light, astronomers questioned the prevailing dogma that the "firmament" (the background stars in the sky) was not unchanging and permanent. In time, we would come to realize that Kepler's Supernova (as it's come to be known) was a white dwarf that exceeded its critical mass and exploded in a brilliant burst.
