Vulcan Points

Can you imagine an island within a lake that is situated on an island located in a lake on an island? Confused? Well, it is really confusing, but this island does indeed exist: Vulcan Points is the world’s largest island within a lake (Crater Lake) that is situated on an island (Taal Volcano Island) located in a lake (Lake Taal) within an island (Luzon).

Can you see the tiny blue shadow in the south of Manila, the capital city of the Philippines? (In the northernmost island, or Luzon Island.)

Lake Baikal: the deepest lake in the World

The world’s deepest lake is Lake Baikal, which has a depth of 1,642 meters (5,387 feet). It is a rift lake in the south of the Russian region of Siberia. Its bottom is at 4,215 feet (1,285 meters) below the sea level. In terms of volume, Lake Baikal is also the world’s largest freshwater lake; it contains roughly 20% of the world’s unfrozen surface freshwater with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.

Live HD streaming of Earth from The ISS – See the beautiful Earth from 400 km above

The live streaming of Earth from the ISS is available on YouTube in HD quality.

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

Calbuco volcano erupts (Chile) – amazing video

Calbuco volcano erupts: the stratovolcano in southern Chile has erupted twice for the first time since 1972 and the people have been evacuated from the area. It is the first eruption of the stratovolcano in 43 years; it results in a huge ash cloud over a mountainous area in the south of Chile.

The amazing footage from the area shows a huge column of lava and ash being sent several kilometers into the air.

Maps can be deceptive

Yes, 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 was developed for navigational purposes and has often been used in world maps. But, 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).

Every map projection introduces distortion, and each has its own set of problems.

If Earth had rings like Saturn, this is what it would look like

What if Earth had rings like Saturn? What it would look like? Probably, our sky would look amazing. The rings would look quite different from the cities and latitudes across the world. It’s interesting to imagine how it would affect the culture throughout time. It would have influenced religion, mythology, navigation, etc.

Earth: a fast-moving Spacecraft

In fact, we’re all living in a fast-moving spacecraft named Earth. Our planet is moving around our sun in an elliptical (an ellipse which is very close to a circle) orbit.

The Sun is (our solar system, the Sun, Earth and all the other planets and objects) whirls around the center of our galaxy, the Milky Way. And, our galaxy and the other galaxies in our neighborhood are also rushing towards a structure called the Great Attractor, a region of space roughly 150 million light-years away from us.

This Great Attractor, having a mass 100 quadrillion times greater than our sun and span of 500 million light-years, is made of both the visible matter that we can see along with the so-called dark matter that we cannot see.

So, even when you’re resting on your armchair, you’re flying through space faster than the fastest human-made object. But how fast actually?
