Live HD streaming Of Earth (From The ISS – International Space Station)

When I was a child, I always dreamed about watching Earth from the space. Back in the 1980s, we were almost sure that around the year 2000, the space travel would be so common. Remember TV shows like “Space: 1999”. Unfortunately, the space race lost its momentum during the 1990s and 2000s.

But thanks to the Internet and computer science, we all able to see the earth from the space. And live! And HD! 24 hours a day (the feed will sometimes go down as the signal switches between the cameras – the screen is grey when the cameras are down)!

Maps can be deceptive

The standard maps we see every day use Mercator Projection, a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It developed for navigational purposes, has often been used in world maps. And like all the other types of projections, it can be deceptive.

In fact, every map tells lie, since it’s impossible to transform perfectly the three-dimensional world into two-dimensional surfaces like paper or computer screen. Map projections are necessary for creating maps and every map projections distort the surface in some fashion (a map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane).

World’s Largest Living Cat: Hercules, the liger (video)

Ligers are the largest cats on Earth. A liger can be more than 900 pounds (~408 kg) in weight and 12 feet (~3.65 m) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).
