Astonishing picture of Earth compared to all its water and air

I’ve seen Earth compared to all its water before, but this image really gives you a perfect idea on how fragile our planet is by adding all the air in another sphere. The density of the air pictured here corresponds to its density at sea level (one atmosphere.)

Comets look like swimming sperms in time-lapse videos

The H-1 camera on board NASA’s STEREO-A spacecraft has captured this sequence of the two comets now en route to the Sun: Encke and ISON. They look like sperms trying to fertilize an egg named Earth—which is quite appropriate, given the hypothesis that comets brought life to this planet.

Watch how the major religions have conquered the entire world

Christianity. Islam. Judaism. Buddhism. Hinduism. All the major religions have basically competed with each other in an epic, historical game of Risk. Who can gain the most converts? Which religion is the most right at being right? Who has the most color on the board? Those who start strong early can flame out, others can try to stay steady while Christianity ends up painting the entire world after establishing key holding grounds.

Sensory Maps Show Locations Along with Their Sights, Smells, and Sounds

Traditionally, maps were made to help people find their way around a city that they might be visiting for the first time. However, Kate McLean took the basic concept of the map and spun it around to come up with an all-new series that have made the jump from being reference materials to art: the Sensory Maps.

sensory map newportInstead of telling you where certain streets or landmarks are located, Kate’s sensory maps will instead let you know what it would feel like if you were actually there. How? By letting you smell its scents, taste the surrounding atmosphere, feel whatever might be there, and hear the sounds in that location.

Of course, it would be impossible to let you experience all these senses through a map – but that’s what your imagination is for, right?

To construct some of the maps, Kate invited people to go to her studio and smell bottles with scents in them. She then had them recall what that scent remind them of and write down the place or feeling that they associated with the smell.

That’s a lot of work, considering that this is just for one of the senses that Kate’s trying to capture in her work.
