Earth is an amazing place. Not only it is a beautiful oasis in the vast, cold space, it also has many interesting features. Here are 10 fun geography facts.
The magnetic field of Earth is constantly changing. And, at the moment, even more rapidly than previously thought – up to 10 times, as British researchers have now figured out. This has significant implications not just for the old-school magnetic compass navigation but also for the proper functioning of telecommunications networks and GPS-and thus for […]
“How long is the Earth” is a weird question – but what if you cut it up into Minecraft sized 1-meter cubes and lay them in a line through space, how far would the Earth stretch? It is a thought experiment and in the video published by the astrophysicist (and a famous poker player!) Liv […]
How the moon was formed? The most widely accepted theory of the Moon’s origin is known as the Giant Impact Hypothesis. The standard giant impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests the Mars-sized body, called Theia, impacted Earth, creating a large debris ring around Earth, and the Moon formed out […]
Andrew Norton, The Open University All stars emit varying amounts of light over time – and the Sun is no exception. Such changes in starlight can help us understand how habitable any planets around other stars are – a very active star may bombard its planets with harmful radiation. Now a new study, published in […]
Roger Barlow, University of Huddersfield Why the night sky is dark? It sounds obvious. That’s what night is. The sun has set and when you look up at the sky, it’s black. Except where there’s a star, of course. The stars are bright and shiny.
Do you remember when did you see a sky full of stars last? It’s been many years for me, I even can’t remember when I saw last. A lot of young people didn’t see even once, because of the light pollution in cities, since they were born in cities and probably never went to the […]
Once (almost) every four years, we have a “leap year” which has 366 days instead of 365. Why it is like that? Why we have leap years? JAXA (Former NASA Goddard) Planetary scientist Dr. James O’Donoghue (@physicsJ) explains why we have leap years in his latest video.
The Japanese Space Agency (JAXA) and former NASA Goddard Planetary scientist Dr. James O’Donoghue (@physicsJ) created another amazing video. He showed that what if we slowly drain the Earth’s oceans and see the two-thirds of Earth’s surface (that is currently under the oceans) we don’t get to see. In other words, how our planet would […]
Urbanization is just one of the many effects of overpopulation here on Earth, along with the rapid dwindling of the natural environment as a whole. The general consensus across the scientific community is that a number of factors have contributed to global overpopulation. More than 7.7 billion people live on Earth as of 2020, largely […]
