In 1868, the spectral pattern of a yet unknown element was observed within light emitted from the chromosphere of the Sun during a solar eclipse. Known only to exist in the Sun at the time, this new element was given a name derived from helios, the Greek word for Sun. Though it was later shown to exist terrestrially (observed within the lava of Mount Vesuvius 14 years later), helium remains the first and only element to see its initial discovery somewhere other than Earth.

NASA recently released imagery showing the deforestation of America …in just 34 years.
Mmmmmm… yeah, that’s not deforestation. That’s called “winter”. The photo on the right was taken in January of this year, and the photo on the left shows clear signs of color manipulation.
Almost all the deforestation that took place in the US occurred prior to the 20th century. Deforestation is one thing that is not an issue in the US. The logging industry is completely sustainable, and has been for many decades. If anything, things are better than they were in 1978.
I’ve been seeing this picture make the rounds, and I thought I’d finally clear that up. :)
