 Live Science: How many satellites orbit Earth?  

The number is increasing fast, which is problematic. 

Human-made satellites were once rare in low Earth orbit (LEO), with just a handful of them rotating around the planet at the dawn of the Space Age in the 1950s. 

But now, there are thousands of satellites swarming around Earth, with even more waiting to join them. 

So, to put an exact number on it, how many satellites are orbiting Earth, and how many might join them in the near future? 

And once all of these satellites are spaceborne, what types of problems might they cause?

Visual Capitalist: From Amazon to Zoom: What Happens in an Internet Minute In 2021?

Today, around five billion internet users exist across the globe. This annual infographic from Domo captures just how much activity is going on in any given minute, and the amount of data being generated by users. To put it mildly, there’s a lot.

Researchers find that going to bed between 10 p.m. and 11 p.m. local time lowers the risk of developing heart disease compared to any other time of night. 

While bedtimes after midnight resulted in the highest increase in heart-related declines in health, the team finds that even bedtimes earlier than 10 p.m. increased the risk of cardiovascular disease in adults.
