Where Earth’s water came from?

Earth is a blue marble in the space: the water, gives our planet its blue color: about 71 percent of the Earth’s surface is water-covered. There is roughly 326 million cubic miles (1.332 billion cubic kilometers) water on the Earth’s surface. Almost 97% of that water is salty (ocean water). But where all that water …

A Scale Model of the Solar System Drawn in the Desert and the Result is Stunning

We evolved here on Earth, and for thousands of years, we just thought the Earth is also the universe, or at least the most important and the biggest part of it. Our brains have been adapted to live on Earth and the basic survival needs. So we can deal with the moderately sized objects which …

Why we should colonize Mars (and other planets and the satellites too)

Alex Kuzoian and Jessica Orwig of Business Insider has prepared a video titled “Here’s why Elon Musk wants to colonize Mars”. In the video below, we see some reasons why we should colonize Mars someday.

Planet Nine – Where is it?

In January 2015, Caltech (California Institute of Technology) astronomers Konstantin Batygin and Michael E. Brown published an article titled Evidence For A Distant Giant Planet In The Solar System and announced calculation-based evidence of a massive ninth planet. Despite they have had started their research to demonstrate that there’s no ninth planet, they reached the …

The Tiny Earth

We are living on a tiny life-bearing rock, an oasis, in a large, very large and hostile desert called “Universe“. The universe is big, really big, in fact, even our solar system is shockingly large compared to Earth. But again, our brains have problems dealing with big numbers and large objects. Jacqui Frank of Business …

Astronomers Think There is a 9th Planet Beyond Pluto – And It’s a Giant!

Astronomers now think there’s a 9th planet in the solar system almost certainly (hint: it’s not Pluto). The farthest planet from our Sun is probably a giant, smaller than Neptune but likely larger than the Earth. It is informally called Phattie, but commonly known as Planet Nine.

If the Moon Were Only 1 Pixel – A tediously accurate map of the Solar System

The title describes itself. Artist and designer Josh Worth has created a great web page which is actually a scaled model of our Solar System. He scaled the Moon to only one pixel (the radius of the Moon is 1,737 km / 1079.322 mi) and put the planets and other astronomical bodies like the Kuiper …

Pale Blue Dot

The farthest spacecraft from Earth, NASA’s Voyager 1 Notes 1 probe took a photo of planet Earth in 1990, from a record distance of about 6 billion kilometers (3.7 billion miles, 40 AU Notes 2) from Earth. The photo is known as the Pale Blue Dot. In the photograph, Earth is shown as a fraction …
