Why does the sky get dark in this picture?


By Simon Leitch and Laura De PreezThe night sky is getting darker.

There is a clear night and a blue sky.

But why does the light go out?

The reason is that it’s being filtered out by our atmosphere, which is made up of dust and carbon monoxide.

The amount of CO 2 in the atmosphere has risen over the past 100 years, and we’ve added more to it than we’ve taken out.

CO 2 concentrations in the air today are about half the levels that existed before the Industrial Revolution.

It is estimated that CO 2 emissions will increase by about 100 million tonnes a year by 2035, compared to today’s levels of about 2.5 billion tonnes.

And there’s a lot more to the atmosphere than just CO 2.

In addition to the dust and other pollutants, the air is also loaded with volatile organic compounds (VOCs), which can react with the air to create ozone, a powerful form of ultraviolet light.

Ozone is a dangerous pollutant that can cause cancer, asthma and other health problems.

It’s not just sunlight that makes the sky dark, it’s also the fact that the air we breathe is filled with a lot of particulate matter.

This includes aerosols, tiny particles that stick to the surface of the atmosphere and are produced by things like cars and planes.

There’s also water vapour, which can form clouds and trap the light.

The amount of water vapouring in the sky has increased over the last 100 years and scientists have even found that we are getting more of it.

This is due to the fact, as the sky gets darker, the sun’s rays bounce off clouds to form a blue glow.

But, as it gets brighter, the sunlight that hits the cloud gets even brighter, producing the blue glow we see.

But we can also see the sky from our windows.

This is what’s known as a ‘skywalk’ and it involves sitting through the night in your favourite seat and then turning on the light and taking a short walk through the dark sky.

This technique is popular in the UK and Australia and has been used by astronauts for years.

But it is only a few years old, and is very difficult to do.

The only way to get a skywalk is to get your own private skybox, which costs around $2,000 to build and costs around £400.

There are a number of ways to get the night sky to appear more or less dark.

Some people opt for bright lights, such as a red or orange bulb, while others opt for dimmer lights, like a blue one.

There are also techniques like ‘night-time binoculars’, which can show the sky in the dark by projecting the image of the stars through the binocular lenses.

In the future, astronomers will be able to measure the amount of the blue light reaching the earth’s surface from satellites such as SkyMapper, which will be used by scientists around the world.

The team behind the project, called SkyMapping, hope to develop the technology and get it into use by the end of the decade.

It is hoped that these techniques will help scientists to understand the changes that have occurred in the skies over the years.

The sky also provides the best view of Earth’s land masses, and the most detailed images of the sunspot cycle, which measures how the suns activity changes in the solar cycle.

It also gives us a glimpse of the solar wind, which blows across the sun and acts like a magnet.

And it’s the blue sky that provides the most detail of Earths surface.

It gives us an idea of how the continents and oceans form, how water cycles work, and even how clouds form.

In addition, the night skies also give us the best chance of getting the best possible viewing of the aurora borealis, which occurs every winter when the Earth is at its most active.

The effects of the ozone holeOn the evening of October 31, the ozone layer will be thickest at about 9:00pm local time.

The ozone layer protects us from ultraviolet light, but also from particles called ozone molecules that get inside the atmosphere.

These particles can act as greenhouse gases, making it harder for the Earth to absorb more sunlight.

We can see the ozone depletion on the evening evening of November 1, as ozone levels are about a third of what they were on November 29.

This means that the Earth’s atmosphere has been stripped away, and that it is now a little more than 4,000 times as thick as it was on November 27.

This thinning is happening because the ozone layers have been stripped by the Sun for a period of just a few days, and this thinning in the ozone is a result of the changes caused by the ozone holes.

As the ozone starts to fall back, the planet’s surface temperature will begin to rise.

At that point, the oceans will start to warm, which means that warmer temperatures will affect the formation
