Is The Great Wall of China Visible from Space?
The idea that the Great Wall of China can be seen from space has been around since at least 1938 and is still popular today. It certainly seems plausible that such a large, linear structure would stand out from the surrounding landscape, but it’s actually not true.
Alan Bean, the fourth man to walk on the moon, said in 1969
“The only thing you can see from the moon is a beautiful sphere, mostly white, some blue and patches of yellow, and every once in a while some green vegetation. No man-made object is visible at this scale.”
But if you can’t see the Wall from the moon, how about somewhere closer to Earth? The International Space Station (ISS) maintains a low earth orbit of between 330-435 km above our planet’s surface.
SCIENCE NEWS – What is Dengue Fever and Could Genetically-Modified Mosquitoes Prevent It?
Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.
Twirling Skye
My name is Skye, and I am eleven years old. I belong to Riverside Reflections, which is a baton twirling team.
My mum teaches us how to twirl, and sets our routines for us. She started twirling when she was five years old, which is quite a long time ago!! I started doing it properly when I was about five.
If you don’t know what twirling is, I’ll try to explain. A baton is a metal stick that is weighted at both ends, and has rubber to cover these ends. It is quite heavy, and hurts if it hits you, so you have to practise lots so you don’t drop it on your head!
