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.)
NASA celebrates the 50th Year of Spacewalking
The National Aeronautics and Space Administration (NASA) celebrates 50 years of spacewalking, or Extravehicular Activity (EVA) with a slogan: “#SuitUp”. The United States government agency, which responsible for the civilian space program as well as aeronautics and aerospace research, will be celebrating accomplishments throughout the year 2015.
The announcement from NASA:
The Exact Moment of the Calbuco Volcano Eruption captured by a hiker
The exact moment of the Calbuco Volcano eruption captured by a currently anonymous hiker in Chile. The volcano erupted on April 22, 2015, for the first time in four decades (the last one was in 1972).
The deepest lake in the World: Lake Baikal
The world’s deepest lake is the 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 fresh water 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 – 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
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)!
Calbuco volcano (Chile) erupts – amazing video
The Calbuco volcano in southern Chile has erupted twice and the people have been evacuated. It is the first eruption of the stratovolcano in 42 years; results in 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
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).
If Earth Had Rings Like Saturn, 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
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. 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 (one light year is about six trillion miles) 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?
