As the sun goes down and the clouds clear, we’ll be left to wonder just what exactly is behind the eerie, darkening sky of the American Southwest.
For many, the answer is that it’s the Milky Way, the vast, swirling disc of space-time that is home to the stars.
For others, it is a dark night sky and dark night skies, where the moon and stars are invisible, and where the sky is gray, or dark, or a mixture of the two.
For those in the latter camp, there is the dark night of the soul, when you’re left wondering just how many stars you’re missing.
The question is not whether you should see them, but if you should be able to see them.
For others, however, there are no stars, no planets, no dark night.
For the last several years, the Southwest has been experiencing a rare period of darkness that is not merely a sign of good weather, but is also a sign that our solar system is now, as the astronomer John Christy puts it, in a “period of rapid cooling.”
What exactly is happening here?
In an age where we’re seeing more and more solar flares, solar flares are nothing new.
It’s been going on for at least 10 billion years.
When solar flares occur, they’re a phenomenon that can last a few hours.
When a flare occurs, it causes a bright flash of energy, or flare, in the outermost solar system.
A flare can last for months, or even years.
In other words, the longer it lasts, the more intense it becomes.
But what causes a flare?
It’s not clear.
In fact, there have been no conclusive answers, except that a star system called Alpha Centauri B, about 20 light-years from Earth, has been getting a lot of flares over the past few years.
In a paper published in 2015, scientists at the SETI Institute in Mountain View, California, looked at a range of different scenarios to answer this question.
They compared what happened to the planet Alpha Centauri in the past 10 billion to what would happen if the sun were fully extinguished.
They found that the planet would have experienced a maximum of about 6 flares per second, about the same as it would have been in the last million years.
The scientists also looked at how many flares would be produced in a given period of time.
For that, they looked at the Sun’s total luminosity, which is how much energy the Sun puts out over a period of minutes.
The higher the number, the larger the flare.
They also looked to see what happened in the first few minutes of the flare, so that they could determine how much sunlight would be emitted in a certain period.
The scientists found that they had to predict about 2 percent of the flares.
The reason for that prediction error is that the scientists couldn’t measure the flares in detail enough to be sure.
But, as they explained in their paper, that is the problem: the more you measure, the less accurate you are at predicting flare activity.
So, the scientists used simulations to figure out how much of the star system would be affected.
In a paper in 2017, they compared the simulated flares with what would occur if Alpha Centauri were completely extinguished.
The simulations showed that, under the most realistic scenario, the planet could be exposed to about 6.5 flares per hour.
If the planet were completely destroyed, they estimated that it would be exposed for 2.5 hours, for a total of about 2.7 hours of exposure.
This means that, according to the simulations, if Alpha Ceti were completely engulfed, it would experience 6.8 flares per minute.
But how many more flares would we be exposed?
And what would the effects be?
The scientists concluded that the number of flares needed to be estimated accurately to get a good estimate of the maximum number of flare events.
In the case of Alpha Centauri, the simulations estimated that about 3.5 flare events would be needed to trigger the flares, which would cause about 100 hours of exposures.
The planet would then be exposed in a period lasting about 8 hours.
For those who are wondering, that’s more than twice as many flare events as the planet is expected to experience.
The paper also looked specifically at what happens to the Sun over time.
As a planet orbits the Sun, the sun’s energy flows through it.
When the planet orbits, the solar wind blows away dust and gas particles that are trapped by the planet’s atmosphere.
This is why the planet gets dark.
This process also causes the surface of the planet to cool.
In the case with Alpha Centauri and the Earth, this cooling would happen at a rate of about 20 to 30 degrees Celsius (96 to 112 degrees Fahrenheit) per second.
If the planet was completely destroyed and the sun was completely extinguished, the average temperature on Earth would drop by about 4 degrees Celsius (-
