A beautiful video, once again, from Michael Stevens, titled “How Earth Moves”. Michael explains many concepts, including “sub-solar point”, “sidereal day vs solar day”, or “how Earth moves in the space” etc, and he is doing it in a very simplified manner. Enjoy!

Elon Musk, the founder, CEO, and Lead Designer of the private space travel company SpaceX announced that “they are planning to get humans to Mars in six years”. In order to achieve this goal, Musk revealed the Interplanetary Transport System, which aims to reach Mars with a human crew for the first time in history.

Previously I posted two articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System“, and “A Scale Model of Solar System Drawn in the Desert and the Result is Stunning“. Since the human brain cannot deal with the really large numbers, these articles provide an amazing way to understand how big actually our Solar System is.
Now, I decided to put the Solar System into scale as an infographic. You can see a scaled Solar System below, the planets’ distances from the Sun, and the first flybys over them. Plus some statistics about the planets and our home planet, the Earth.

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 Earth’s water came from?

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, our minds, has been adapted the life on Earth and the basic survival needs. So we can deal with the moderate sized objects which have moderate velocity, we can understand the small numbers like 1, 2, 50, we can conceptualize the small distances like two kilometer, or the distance from our “cave” to the nearest river. But when the numbers and distances get bigger, I mean much bigger, like the distance from Earth to the Sun, it become incredibly difficult to conceptualize.

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, we see some reasons why we should colonize Mars someday.

NASA has published an amazing Mars footage to celebrate 10th anniversary of Mars Reconnaissance Orbiter (MRO), which was launched August 12, 2005, and attained Martian orbit on March 10, 2006. The images in the video below taken by MRO’s HiRISE camera are not in true color because they include infrared information in order to be optimized for geological science.

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 exact opposite result: there must be a ninth planet beyond Pluto, and it’s probably 10 times the mass of Earth (for comparison, Neptune has 17 times as much mass compared to the Earth).

Edgar Mitchell, the American naval officer and aviator, test pilot, aeronautical engineer and NASA astronaut and the sixth man to walk on the Moon, died on February 4, 2016 aged 85.

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 the big numbers and the large objects.
Jacqui Frank of Business Insider has prepared video comparing our planet with large objects (and distances) in the Universe. These amazing to-scale visuals will help to recognize how small (and fragile) our planet is.
