Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.

In the last few thousand years, humans have had a powerful impact on Earth. Within a geological blink of an eye, we exploded out of Africa to colonize virtually every inhabitable space on the planet. We dammed the rivers, we domesticated animals, deforested many areas, changed the chemistry of atmosphere and he seas… list goes on. But, what would happen if humans suddenly become extinct in the future?

Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. But if you don’t know where to look, you won’t notice it. But if it were much more brighter, its appearance in the sky would be sensational. The moon is a good reference about what we’d see in the image below:

When it comes to big numbers, very big numbers, human brain is weak. In fact, our brains cannot deal with the really large numbers. That’s why when the subject is Earth, planets, Solar System, galaxies, and in general, the Universe, we cannot truly conceptualize the things. A lot of people think we’re “conquering” the space (we are far, far away from that – and maybe we never will), or the “aliens” are regularly visiting Earth, as if it is just an hour’s drive from there. In fact, these people don’t truly understand what are they talking about, how big is the universe, how far the stars are, and how the Earth is a tiny, tiny spot in a vast space we are still striving to understand.

If the population of the world was only 100 people, instead of 7.4 billion, while the statistics remaining the same, what would today’s society look like? A video published by GOOD Magazine (produced and written by Gabriel Reilich, animation by Jake Infusino) answers that question.

The Earth is getting more crowded every single day. As of August 2016, the world population was estimated at 7.4 billion. Our planet is already overpopulated, and despite the growth of the population begun slowing, the situation will be worse: the United Nations estimates it will further increase to 11.2 billion in the year 2100.
Here is a video published by the American Museum of Natural History showing the World’s population through time.

Earth is an amazing place full of stories, beauty and natural wonders. Here is an amazing drone footage of Iceland and Norway, from volcanic landscapes and geysers of Iceland to the fjords of Norway. The video is titled “Nord” (Catalan, Danish, French, German, Italian, Norwegian and Swedish for north), captured during a summer trip to Norway and Iceland in August 2016. The accompanying music is also beautiful. Enjoy!

In 240 BC, the Greek astronomer, geographer, mathematician, music theorist and librarian Eratosthenes of Cyrene (c. 276 BC – c. 195/194 BC) calculated the circumference of the Earth without leaving Egypt. Here’s how:

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!
