One of the fantastic and vital features of planet Earth is our atmospheric shield. We have often mentioned the NASA website Astronomy Picture of the Day (apod.nasa.gov). Every day NASA posts a different astronomy picture to show us something of the cosmos. This is an excellent service because most of us don’t have access to giant telescopes, and we can’t see light in wavelengths outside of the visible spectrum.
On September 12, 2020, NASA’s posting showed a time-lapse series of pictures taken by the New South Wales observatory in Australia. This observatory is located at 33 degrees south latitude in an area with minimal light pollution, so there is minimal obstruction of the night sky. The pictures were recorded on 372 nights and run like a movie. What you see are sporadic meteors, fireballs, meteor showers, and even a lightning sprite. The series shows over 1000 meteors.
Remember that this picture sequence shows a relatively small area of sky. This does remind us that there is a constant rain of dust, pieces of rock, and other debris coming down upon our planet. People working with communication satellites are well aware of this because of constant damage to the orbiting objects. For those of us on Earth’s surface, our atmospheric shield burns up most of the solid space material. We don’t have to worry about getting hit by space debris or getting sandpapered by the small dust particles coming from outer space. That is just the solid stuff. Our atmospheric shield also refracts away non-solid radiation such as x-rays and gamma rays.
Providing a place where life can exist is not as easy as some think. One of the reasons we are not finding life in outer space is that designing and implementing our atmospheric shield was vital for the existence of life, and doing that was not simple. It required intelligence and a carefully implemented design. The simple statement, “In the beginning, God created the heaven and the Earth” doesn’t tell us the incredible difficulty of doing that.
