The European Space Agency has just released images showing all the satellites and human-made debris now orbiting space as a result of 51 years of launching stuff since Sputnik. That's about 6,000 satellites up there—of which only 800 remain operational—plus thousands of other objects from launches and accidents. According to their mindblowing simulations things are getting a lot worse:

About 50 percent of all trackable objects are due to in-orbit explosion events (about 200) or collision events (less than 10).

Yes, we knew that there was a lot of crap out there, but not to this extent. According to the ESA, this is really bad news and urgent measures are needed. Explosions in space are not disastrous on their own, but because of the aftermath. One example: a geostationary satellite travels at 6,213 miles per hour. If it explodes, all the debris stays near the orbit, forming a cloud around the Earth within a few days, as this simulation shows: …
