The Ponzo Illusion


Have you ever noticed that when the moon is directly on the horizon, it appears to be a lot closer and larger? Known as the Ponzo illusion, your brain inflates the size of the moon to make it appear larger than it really is. Don’t believe it? Next time you’re looking at an oversized moon block everything else out with your hands and watch it shrink.

Upon leaving the moon, astronauts on the Apollo missions described moon dust as smelling like gunpowder and feeling extremely soft. Scientists, however, are still not exactly sure why this is because the two have extremely different compositions with moon dust consisting mostly of small shards of silicone dioxide glass.


Biggest Diamond Ever


In 2004, scientists discovered the largest diamond ever. In fact, it’s a collapsed star. Measuring 4,000 km (2,485 miles) across and having a core composed of 10 billion trillion trillion carats, it’s roughly 50 light years from the Earth.

Strangely enough, Venus completes an entire orbit around the sun before it manages to turn on its axis once. This means that its day is actually longer than its year.

As big as the planet Saturn is, if you were to put it in a glass of water, it would float. This is because its density is .687 grams per cm cubed, while water is the famous .998 g per cm cubed. Unfortunately, though, you would need a glass that is over 120,000 km (74,564 miles) in diameter to witness this.
