The space around the earth is becoming increasingly filled with satellites.
Research, internet and other communication are crowded around the space.
Technological advances have positive effects, but at the same time new problems are created when astronomers chase the answer to life's big questions - everything from how life was once created, how a star dies.
But now the International Astronomical Union is to form a center to protect the night sky.
Among other things, they will work with industry to minimize the risk of interference, and work with satellites being built from materials that do not reflect sunlight.
- It is very important, otherwise there are a lot of discoveries we will not be able to make.
See examples of how research is hampered by the satellites in the clip.
