There is a very, very cool interactive demo that Nikon is presenting over on their site called the Universcale.

Let’s see, how can I describe it… well, it’s kind of like this video which I previously posted that shows how the size of our planets relate to other objects in the universe, except that the Universcale is interactive and also goes the other way all the way down to subatomic particles.

As a follow up to my previous post of The Most Important Photo Ever Taken, here is a very interesting video illustrating the relative size of planets in our solar system as well as stars throughout the galaxy.

The largest star illustrated is 753,320 times larger than Mercury. It would take 2.185 TRILLION humans standing head to toe to stretch across the diameter of that star, or 364 times the entire population of Earth.

Well, with the exception of those people who don’t believe we’ve even built the Hubble or gone to space… I guess if you think the whole thing is a hoax then you can keep on believing the Earth is flat. :-)

Google has added some fascinating footage of the moon to commemorate the anniversary of our Apollo moon landings.

This is interesting from a historical perspective, but even more fascinating is the incredible detail of the moon surface that can be seen when you zoom all the way in. I guess this definitively answers all questions regarding what the moon surface is made of.
