The exosphere is also the region where some satellites orbit, particularly those designed for long-term observations of Earth or communications. The low density of particles in this layer means that there is minimal drag on these satellites, allowing them to maintain their orbits for extended period...
When that wind slams into Earth's ionosphere, or upper atmosphere, the aurora is born. In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it's called the southern lights (aurora australis). "These particles are ...
What is a quantum vacuum? Anne Baring A True Vacuum? One may have heard that a vacuum is nothing—the absence of matter. Space is typically called a vacuum, but even it has minute material in the void that makes it a non-but-near-vacuum as a whole. On Earth, we can isolate a ...
It’s important to remember that these findings apply to healthy, trained individuals. For those with existing health conditions, the situation may be different. Individuals with knee problems, back pain, obesity, and other health issues might already struggle with Earth’s gravity of 1g. Increased...

What it says about you:You’re not a complicated person. You love the Mercator projection; you just wish it weren’t square. The Earth’s not a square, it’s a circle. You like circles. Today is gonna be a good day! Summary: ...
At the top of the list sitsJava,Indonesia’s most populous island and the most populous island on Earth. Over 150 million residents inhabit the 130,000 km² landmass, resulting in a density of nearly 1,200 people/km². 排在榜首的是爪哇岛,它是印度尼西亚人口最多的岛屿,也是地球上人口最...
The industrial sector's contribution, which dominates the GDRP, on the one hand increases economic development and on the other hand decreases environmental quality. Most of it is generated from the industrial sector's contribution, which harms environmental quality such as water pollution, air pollut...
All it needs is some good marketing. One selling point might be that most if not all mined iridium ultimately comes from meteorites, which contain 300-1500 times as much iridium as the earth’s native crust. OK, that’s iridium. Now here’s the weird deal on osmium. A series of web...
