Why We Don't See Stars from a Plane

Why We Don't See Stars from a Plane


Hello friends,     If you’re on an overnight flight, you might have been looking forward to a gorgeous, Clearview of the stars. That’s the whole reason you booked that window seat, right? But when night falls, you look out your window, and…no stars! They’re obviously still there…so what’s going on here?? 


Why We Don't See Stars from a Plane

     Well, there are a few reasons and I’ve got them.

1.   The Lighting in your cabin Obviously, the yellowish-whitish light in your cabin isn’t natural light, and there are rows and rows of these lights from the front to the back of the plane. Plus, other passengers may be watching an in-flight movie. In other words, it’s brighter inside the plane than it is outside. No matter how dim the lights might get as they’re turned down around bedtime, there are enough of them to make it difficult to see the stars – which, keep in mind, are still quite a few miles away.

2.   Light Pollution Similarly, when you’re flying over a huge city like New York, London, or Tokyo, the stars still have to compete with all of those artificial lights from the cities. This concept is called light pollution. It might seem crazy to think that man-made lights will block out the light of millions of stars, but the stars are much further away than those glowing city lights below.

Night Pollution

3.   Skyglow A lot of light pollution, like the kind you'll get flying over a big city, can cause skyglow. Even if you aren’t flying directly over it, you can still see a big city to the left or right of you from a plane. Of course, even a big city will seem small from a plane, but there can be a huge glowing atmosphere around and above the city from all the lights. That’s what skyglow is, and it’s bright enough to block out even the light of the stars

4.   The Moon and its Light, Even if it’s a clear night and you're above the clouds, the moon may be shining so brightly that its light will block out the stars. The moon still blocks the light of some stars when you’re stargazing from Earth. Even if you can’t see the stars from your plane, take the opportunity to enjoy a beautiful, unobstructed view of our moon.

5.   Proximity to the Stars, It might feel like you’re much closer to the stars while up in your airplane, but in terms of miles and light-years, you aren't really that much closer. After our moon and the sun, the star that’s next closest to the earth is called Proxima Centauri, and it’s 4.24 light-years away. 1 light-year is 6 trillion miles. When thinking in terms of numbers that big, if your plane is only somewhere around 35,000feet off the ground, you’re not that much closer to the stars than you are from Earth anymoreDisappointing, I know!

6.   Atmospheric Turbulence Simply put, atmospheric turbulence is irregular air currents that are mixed around by the wind. Besides making your flight bumpy, this turbulence also stirs the air, which can move gasses, smoke, and vapors around the sky. This keeps these substances from settling in one air pocket and keeps the atmosphere healthy, but my point is that turbulence may bring in clouds, even on a clear night, which will block your view of the stars. Pay attention to see if it’s windy; if so, this may cause turbulence and bring the clouds rolling in. Yeah, stick your head of the airplane to see if it’s windy…ha..never mind.

7.   Your Retinas, The retina is the part of your eye that processes lightIf you have any pre-existing conditions, such as diabetes, or have had any head trauma, your retinas may not work properly, and you may not be able to see the stars. Even healthy retinas need normal oxygen levels in the blood to work properly. Although the cabin will maintain pretty normal oxygen levels at a high altitude, any of these pre-existing conditions, or less than perfect retinas, may affect your ability to see the stars from your plane.

8.   We Don’t Have Night Vision Well, at least not right away. There are other parts of your eyes besides your retinas that help you see in the dark, and your brain has to do some work, too. It takes us 10-20 minutes for our eyes to acclimate to the dark. So if you’re trying to see the stars from your plane and can’t, don’t give up too quicklyIf you’ve eliminated the light sources inside the cabin, whether by using your blanket or getting the cabin lights turned off, keep stargazing for at least 20 minutes. You have to give your eyes time to adjust.

9.   Your Windows, The windows of an airplane are oddly shaped and on the small side, only reaching from about shoulder to elbow; not ideal for stargazing. The cramped nature of the seats makes it difficult to look out your window from multiple angles tooYou’d have to do a lot of neck-twisting! Airplane windows also have three layers of protection against the outside, so you stay safeAnyone of these panes may be scratched up or cloudy due to age. The shape and condition of your window may affect the quality of your view of the skies. It might be hard to get this near-perfect conditions. 


Why We Don't See Stars from a Plane

     So, it has to be a clear night. The moon needs to be dim. Your cabin has to be dark. You can’t be flying over any big cities that may cause light pollution or skyglow,etc., etc. It could be difficult to get all of these elements to line up at the same time! Most of these conditions are out of your control, like all the natural elements outside. But if the right circumstances fall into place, your chance to stargaze above the clouds just may come along. So what CAN you do to increase your chances of seeing the stars from your flight? It might be difficult to see the stars, but it isn’t impossible.

    First, don’t do this during the day. Just kidding. Okay, Assuming that it’s a clear night, one option is to cover your head and sides of your face with your travel blanket. The goal here is to block out all the unnatural light from inside the cabin. Then, lean toward the window until you can see out, but the sides of the window are bordered by your blanket too. You might get some curious glances, but you may be able to do a little stargazing from your plane. 


    Next don’t do this from the middle or aisle seat. The folks won’t take it too kindly if you flop over onto them to gaze out the window. You could also try asking the flight attendants if they could shut off the cabin lights fora minute or two. This would help make it almost as dark inside the cabin as it is outside. Without some elimination of the lighting inside the cabin, you won’t be able to see the stars at all. But, if you’re flying over an area with no skyglow or light pollution, and the lights are off in the cabin, you should be able to see some stars once your eyes adjust.


Why We Don't See Stars from a Plane

    Hey, It can’t hurt to ask! Some food for thought: in the early days of air travel, like in the ‘30s and ‘40s, pilots didn’t have all the technology on the flight deck that we have today. So how did they successfully navigate? They used the stars, or celestial navigation – similar to how sailors did! It’s much easier to see the stars from the larger and cleaner window in the cockpit. In the old days, the North Star and the constellations were tools of the trade! Seeing the stars from your plane is not only possible, but it used to be absolutely necessary! What’s that you ask, where are the best places to stargaze from an airplane?


    Obviously, the view from the bathroom isn’t good, so like I said try a window. If you’re doing some nighttime flying over Idaho, Utah, Colorado, or British Columbia, you just might be in for the sight of a lifetime. These parts of the U.S. are homes to many protected national parks and nature reserves, so there’s no danger of light pollution or skyglow. Skies tend to be pretty clear and cloudless in these places, too. If you’re flying over British Columbia during the wintertime, you might be lucky enough to catch a glimpse of the Northern Lights! Kinda depends on what side of the plane you’re on.

   So hey, if you learned something new today, then please share this article with your friends and family. And please let me know in the comment box, how is it.

What If Earth Started to Spin Backwards

What If Earth Started to Spin Backwards


Hello friends,
         In this article, I am going to write an interesting topic on "What If Earth Started to Spin Backwards." We know our planet rotates around its axis from west to east at a speed of over a thousand miles per hour at the equator! And this pattern has lasted for billions of years since the Earth was formed.
   But “what if one day, our planet suddenly started to rotate backward, from east to west?"



     So hey, let’s put a “different spin” on it, shall we? HahaπŸ˜„…It would be one thing if the Earth's continents and oceans were situated symmetrically against the equator when the change of the direction happened.
    In this case, the only change people would notice the climate, which would turn into a mirror image of the current one.

     In other words, there’d be no dramatic changes. But since life on our planet is rarely about symmetry, the effects of the Earth rotating backward would be way more complicated.
    But keep in mind that everything will depend on how our planet would change the direction of its rotation.




     For example, let's imagine that it happened suddenly! Like, one day, the planet was calmly rotating from west to east, and then, in the blink of an eye, it's already moving backward, from east to west.
    Remember, in the very beginning, I told you about the speed of the Earth's rotation? So, in the case of an abrupt switch of the direction, an instant change in speed would make about 2,000 miles per hour!
    Well, hold onto something! That means that everything not fixed to the ground would be hurled eastward. Buildings and other man-made structures would collapse, sending tons of debris into the air and creating chaos. The sudden change in direction would move all the water on the planet, which, in turn, would create vast tsunamis. They’d move across the planet, destroying everything in their path and literally changing the whole structure of the Earth. Oh, and don't forget about hurricane-force winds, which would essentially wipe out everything still standing after the massive waves.



     In short, the Earth would turn into a gloomy, muddy mess. But let's not dwell on this highly unlikely scenario and, instead, picture how different our planet would be if it rotated from east to west right from the beginning. 


   In this case, you would see the Moon and the Sunrise in the west and set in the east. But that would be the smallest of all the differences. The thing is that the different spinning direction of the planet would create unexpected weather conditions on all the continents, and the Earth itself would be a totally different placeSome regions of the world would be colder than they are now. 
   For example, western Europe would be plagued by severe, freezing winters every year. And, vice versa, Russia would warm up and lose the title of one of the coldest countries in the world. Some areas of the world would become much greener than they are as we know them. Other regions, on the contrary, would turn into deserts. 

   For example, North America would be nothing more than a dry dust bowl. In South America, the Amazon rainforests would get replaced by arid sand dunes. But the area from the Middle East to Central Africa, on the other hand, would be covered with lush, dense forests. And the rest of the deserts would be either covered with grass or scattered trees. 

     Do you think such dramatic changes have already happened sometime during the history of our planet? Write about your opinion in the comment section below! πŸ’¬πŸ’¬πŸ’¬

     Anyway, the east-to-west rotation would also influence ocean currents. Few people know that nowadays, the climate on our planet is greatly influenced by AMOC- it's an ocean current that transports heat all over the world. On the forward-spinning Earth, this current is in the Atlantic Ocean. 
   But should the planet start to rotate backward, AMOC would move to the Pacific. It’d be a bit stronger than the original current, and it’d bring more heat to eastern RussiaIn general, there would be much more greenery on our planet, and, therefore, more oxygen for everyone to breathe.


      On the other hand, that might not turn out to be such a great thing. Now, the ocean is swarming with phytoplankton bacteria. But on that different Earth, instead of plankton, cyanobacteria would dominate. These billion-year-old bacteria were some of the first inhabitants of our planet. 
   But the problem with them is that they pump out huge amounts of oxygen. Now if they replaced all other kinds of bacteria, they would completely transform the Earth's atmosphere. Thus, it would contain so much oxygen that people would simply be unable to breathe and, therefore, it would be hard for them to exist on the planet! That's why the chances are high that on a backward-spinning Earth, people would be replaced with a completely different species. 



   But even if it did happen, we wouldn't know about that, would we? In any case, it's almost impossible to imagine the conditions that could make our planet begin spinning backward! So, I guess this is just one of those hypothetical questions like "What if the Earth's core cooled down?"
   But wait, indeed, what would happen then? We’d have quite a cool core of course…Now somewhere incredibly deep beneath the surface of our planet lies the Earth's core- a ball of scorching-hot iron which is surrounded by boiling liquid metal.



    The temperature of the Earth's core is more than twice as high as the temperature on the surface of the Sun! And so far, it seems to work well for all of us. But could the planet function if its core turned into a frozen rock? One of the things that makes life on the Earth possible is the geomagnetic field. It's like a powerful superhero that protects us from all the harmful stuff attacking our planet from space, including highly charged particles from the sun and cosmic radiation. What's more, thanks to this geomagnetic shield, solar winds can't strip away the Earth's atmosphere. You may ask, "What does the geomagnetic field have to do with the red-hot core of the planet?" The thing is that this very field is created by the Earth's core! You don't notice it, but when the planet spins, the speed of its solid inner core and the speed of its liquid outer core are different. 



     As a result, the speed difference creates electric currents, which, in turn, generate the geomagnetic field. Now, let's imagine that both parts of the Earth's core cooled down for some inexplicable reasonIn this case, the worst would happen - our planet would simply lose its magnetic field! Uh-oh, but if there’s no magnetic field, there's also no atmosphere! That's why sometime later, the Earth would start to resemble Mars a little bit too much for my liking.
   First, you wouldn't be able to breathe without an oxygen mask and a pressure suit. Rocks, gas, water, and everything else wouldn’t be heated by the boiling core anymore. The Earth would grow colder and colder. There would be no earthquakes; volcanoes would stop spewing lava, and the continents wouldn't be drifting apart bit by bit as they do now. Unfortunately, people wouldn't be around to feel happy about the geological stability. The eternal cold and lack of oxygen would either finish us or prevent us from living normal lives. And then, there would be the massive problem of protecting the planet from space radiation, remember? 

   It's not very clear what exactly would happen to the planet if it lost the electromagnetic field, but it wouldn’t be anything good. The Earth would probably see a radioactive wave onslaught, which would overheat it to a degree (to a degree) at which it would become uninhabitable. Or it would suffer from solar wind attacks, which would sweep away the oceans, seas, lakes, and rivers. But whichever guess is correct, the Earth would turn into a lifeless, cold rock in any caseWhew! Kinda shakes you right down to the core, huh?
   Well, the only thing I can say at this point is, Let’s take care of this earth, the only home we have in the universe, and “let’s keep spinning, let’s keep spinning”….



   So hey, if you learned something new today, then please share this article with your friends and family. And please let me know in the comment box, how is it.

Should You Shut Down Your Computer Every Night?

Should You Shut Down Your Computer Every Night?


   Hello friends, In this article, I am going to write an interesting topic on "Should you shut down your computer every night?" Really this is an interesting topic and after reading this article on "Should you shut down your computer every night?", you will easily understand and solve your confusion. And in the end, there is a video on this topic from Brightside, please watch the video for better understanding. So let's start...


Should You Shut Down Your Computer Every Night

     You probably heard that turning off your computer for the night can be harmful to it. But you must’ve also heard the conflicting point of view that you actually should turn it off when not using it for long. So what’s the right thing to do then? Well, turns out there are several answers to that.

     The belief that your desktop should work all the time comes from the dawn of the computer era— the 1980s. Back then, computers were made of different materials, and frequently turning them off and back on could potentially damage them.
    Today, there’s no such problem, and you can freely switch your desktop or laptop on and off without much harm. Still, when you turn on your computer, it triggers a little power surge that creates some stress on the system. It isn’t likely to be hard on your electricity bill, but it could still cause some inconvenience.


Should You Shut Down Your Computer Every Night

  • read the beautiful short love storyclick here


      Others argue that when your device is shut down, it saves more energy than you spend when it turns back on with that surge. So the situation seems dubious at best. It becomes clearer when you realize that modern computers, be it laptops, desktops, or tablets, are specially designed not to be turned completely off. Engineers have taken note of how inconvenient it is to close all the apps you have running, save and close all your work, and shut down, only to wait until the device boots when you switch it on again.

      If you have a solid-state drive, it might be fast, but with a conventional hard disk drive, boot-up could take a lot of time, especially if it’s old. Many of the computer parts have moving parts of their own, and they need time to get up to speed.
    When you shut down your device, it first closes all the programs running on it for all users. That means all the documents you were working on will have to be opened again, and those two dozen tabs in your browser will close too. Modern browsers allow you to begin where you left off even after a shutdown, of course, but that’ll still require some time. 


Should You Shut Down Your Computer Every Night


     When everything’s closed, the computer turns off all that’s left and clears its running memoryIt sweeps all the bits and pieces of programs, leaving your system spick and span. This allows it to perform better next time.

     If you don’t turn it off, many programs will leave traces of themselves that are going to accumulate, slowing down your system. So it’s either shut down the computer and wait until it boots up again or leave it on, like, forever, right? Nope.

      There are several things you can do as well. They are hibernation and sleep mode. Both of them allow you to leave your computer on and save your work while reducing energy consumptionYou can access them from the Power settings both on Windows and Mac. Sleep mode conserves energy a bit worse than hibernation, but it allows your computer to start up almost immediately. It puts everything that’s opened on your device into RAM, or random-access memory, which is responsible for current activities on the PC or laptop.


Should You Shut Down Your Computer Every Night?



      When a process is within RAM, it means you can access it right away and it won’t need time to load. Then your device goes to power-saving mode and pauses all activity. To exit this state, just press a key or click your mouse, or pop your cheek like this [pop]no that won’t work – just kidding. Your computer will come alive again. On some systems, though, you may need to press the power button instead.

     Hibernation is a deeper sleep mode that doesn’t use any energy at all, just like when you shut it down but takes more time to shake off. In this state, your computer copies everything you have opened to the hard drive instead of RAM, and only then falls into a slumber. Like I said, hard drives have moving parts that need to gain some spin before you can use them, that’s why your computer is slower to wake up from hibernation.
    If you have an SSD, though, you shouldn’t even notice the difference from sleep mode, since it boots up much faster. Take note that in the more recent systems there’s no obvious choice between sleep and hibernation when you click the Power settings. You can check which one your device is using by going to the system settings.

     On Windows 10, you can only use sleep mode by default, and to add hibernation you'll need to open the taskbar and type power options. Click on the first control panel that pops up and select Choose what the power buttons do on the left-hand panel. Next, click Change settings that are currently unavailable.In the Shutdown settings at the bottom of the screen, tick the box next to Hibernate.


Should You Shut Down Your Computer Every Night?

    On Mac, you’ll have a different default mode for desktop and portable computers: sleep mode for desktops, and hibernation for laptops. Both have been chosen for better performance, so you don’t need to change them. You can still do that, though, but it will require administrator rights and tampering with the system, so use this option at your own risk.
      I don’t want you to end up with a computer that doesn’t wake up anymore, so no, I won't tell you about that. On Mac laptops, there’s also an option to enter a standby mode. The device will automatically enter this state after three hours of sleeping if there nothing connected to it, including the charger. It’s convenient because it will conserve energy for up to 30 days if everything’s perfect. It still uses some charge, though, so don’t hold it for too long. With that many options to choose from, shutting down your computer at all may seem redundant, but it’s not. 


Should You Shut Down Your Computer Every Night?


     Remember I said that, upon shutdown, the machine clears the memory? If you don’t do that from time to time, you’ll get stuck with a slow and sleepy device at some point. Programs it runs all the time will leave a lot of trash under the hood. They will take up important space and prohibit other stuff you run from accessing it.That game you launched a couple of days ago will leave little bits of data to help you start it faster next time, but if you run another program, it might need the space the game has taken. It will eventually find where to save its own data, but it’s going to take more and more time the longer you keep your computer turned on.

      Shutting down the device will solve the problem in most cases. But keeping your data safe while your computer is on is tricky because there can be power surges or outages. It’s mostly okay for laptops since they simply switch from plugged-in mode to autonomous mode, but if you own a desktop computer, you’re in for an unpleasant surprise when you come backMake sure to buy a UPS, or Uninterruptible Power Supply, to save you from headache in case of a power outage.


Should You Shut Down Your Computer Every Night?


     UPS is a device that will provide an emergency power load to your computer if the mains power suddenly isn’t there for some reason.Sounds like a generator, but unlike one, a UPS turns on almost instantly, so your device won't forcefully shut down. On the downside, it only has a charge for several minutes, so you’ll have to be quick to turn off your computer yourself. Or, if you do have an auxiliary generator, it will have enough time to switch on to save you the trouble.

   Hey, I hope you understand well and learn something new if you learned something new today, then please share it with your dear & near ones. And please let me know in the comment box, how is it.
