This remarkable fact has been known for only about 50 years, ever since radio telescopes have been able to peer beneath Venus’ thick clouds and track its slowly rotating surface. This inferior conjunction — when Venus and Earth are the closest — occurs today. […]
Humanity is under attack. The attack is not from large tentacle-flailing aliens, but from invaders so small they can barely be seen, and so strange they are not even clearly alive.

Follow a sunset on a clear day against a distant horizon and you might glimpse green just as the Sun disappears from view. The green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere. Shorter wavelengths refract more strongly than longer redder wavelengths and the […]
