Some astronomers say the growing number of satellites orbiting the Earth is making it harder for them to observe and learn from the universe.
Scientists Discover Water On The Moon
Scientists recently found out there is 100 times more water on the moon than they thought there was.
Scientists discovered the water when they looked at some pieces of moon rock.
They found water in tiny samples of magma, which was trapped in crystal. Magma is a rock made from cooled lava.
Canadian Astronaut Chris Hadfield told Teaching Kids the News that the water is a very valuable discovery.
“It’s like finding diamonds or gold in a remote frontier,” Hadfield said.
