it's winking not blinking they fancy you

To find an asteroid two consecutive images of the same region of the sky in which an asteroid was assumed to be located are photographed through a telescope. The images are then processed for clarity, and then stacked, which will allow them to be animated, or flipped back and forth between them, creating an illusion of movement, or animation. This process is what we call blinking, as the images are alternately blinked on the screen.\n\nWhen the images are properly registered, or lined up one on top of the other, the objects in them that have not moved appear in the same places on the computer screen, these are stars.  The object that have moved are asteroids.

Stars are burning like our sun. Planets aren't burning like our earth. Planets usually orbit around suns.

If stars twinkle due to the atmosphere, then why the planets and moon do not twinkle?\n\nTwinkle, twinkle, little star, how, I wonder, what you are?\n\nOn a clear night only about 2000 stars are visible to the naked eye.\n\nThe nearest star, Centauri, is at a distance of 4.3 light years; that is at a distance of about 2, 60,000 times the distance of the sun.\n\nEven this nearest star appears to be a point from earth.\n\nTherefore, a point image is formed in the retina our eye, that is they fall on very few rods of our eye. \n\nEven a sight turn of eye ball will shift the image position in the retina. This causes the twinkling effect of stars.\n\nBut if we view a star continuously we can’t feel the twinkling effect. \n\nHowever, some stars vary their brightness periodically; they are long period variables and short period variables. Their period varies from a week to months.\n\nHence they are not the cause for twinkling.

we blink to keep moisture on our eye so it doesn't dry out--when it does start to dry your eye will feel itchy and super uncomfortable--there is some people that can withhold blinking for long periods of times but not "a couple of hours" plus blinking is implusive most of the time meaning that we can't control it our body just does it for us-kinda like breathing\n\nif you found this helpful please select as "best answer" so both me and you get points!

Some stars might have a solar system, but not all do.  Some stars are actually two "suns" orbiting around one another (called a binary star) but appearing to the unaided eye as a single star.  Some are even three stars together, such as alpha centauri, which is the closest "star" in the sky--though it is actually three stars that look like one.  Some are stellar clusters, where many of these "suns" are all bunched close enough to appear as one star.  Some are entire galaxies, with billions of stars, but so far away that they appear to be a single star from earth.  Some are stellar clusters, where many of these "suns" are all bunched close enough to appear as one star.\n\nSome things you might think are stars are actually planets.\n\nSome are dead "suns," where the fuel for the nuclear fusion that makes the sun burn has all been expended, leaving a big mass of iron, that glows white-hot for many years before turning dark.  If you look at these so-called "white dwarves" through a powerful telescope, you can see a faint ring of matter that has been blown away in the explosion that came when the star died.  Some stars are huge, and some are small.\n\nSome of the stars we have been able to see have solar systems of their own, which we detect by the slight wobble caused by the gravitational pull of the planet (or planets) as it orbits.

NO, because our eyes are normally closed when we sleep... Blinking occurs naturally and is triggered by our brain when it detects that the the eye needs moisture. Blinking at some point can trigger our tear glands to release liquid to help avoid dryness.\n\nThe phenomenon you see when a sleeping person seem to jitter his eyes when close is called R.E.M. or Rapid Eye Movement. This usually happens when a person is dreaming in his sleep.

A neutron stars is a dead star, a stellar corpse. Corpses don´t die. They are already dead...\nActually neutron stars are pretty active for a corpse. They spin and send out radiowaves. We call those pulsars and can spin around its own axis in milliseconds. Eventually they spin slower and slower. The faint glow they still emitt because of heat from the gravitational crunch will flicker and fade. This will take many billions of years and the neutrons that made up the neutron star will still be ther. It will just be harder to see than now.\n\nBut there may be more dramatic fates for neutron stars. We know they are the remnants of a type II supernova that occurs when a massive stars die. But there is another type of super nova, type I. Those are even more powerful than a type II. Some evidence suggest that type I supernovas are the result of two white dwarfs (remnants of lighter stars) crashing into each other. There is also no trace of a remnant body after a type I supernova suggesting that the event totally annihilated the white dwarfs that caused it. So what would happen if two neutrons stars collided? It would be one heck of a bang!

I think maybe the separation is smaller than the resolving power of my eyes rather than the angular separation of my eyes. So I can't resolve the two sources and just see one bright star. \n\nBest of luck - Mike

the twinkling of a star is due to the atmospheric refraction of starlight.Star light travels from rarer to denser medium (hot to cold) so the atmosphere bends the star light towards the normal.That's why it appears slightly higher than the actual position of star when viewed from the horizon.\nBut the apparent position of the star doesn't remain stationary as the physical conditions of the atmosphere is always changing.Therefore the apparent position of the star fluctuates and the path of rays commin from the star goes on varying slightly.Thus the star light entering the eye fluctuates (increase or decree_ randomly with time.Due to the light flux entering the eye the star appears brighter sometime, fainter.Thus the fluctuating apparent position of the star gives rise to the twinkling of starts.\nnow u may ask why plants dont twinkle..its box they are not very distant as the stars.Stars can be considered as a point source of light where as the plants can be considered as many source of light such that they nullify the twinkling effect,Hence, turbulent atmosphere is unable to cause sufficient variations of star light entering our eye.

Planets and stars can both twinkle, its called astronomical scintillation.  In short it is caused by fluctuation in air density and temperature.  Since stars and light both send light to earth (planets reflect a stars light whereas the star produces it's own) the twinkling effect can be seen in either.  And thus if you were standing on another planet, it IS possible that earth would appear to twinkle.  It's not guarenteed, but if the light coming from earth passed through some varying densities and temperatures it could appear to twinkle.

The stars are out all the time it's just that during the hours of daylight it's too bright to see them.  There will be stars every night, whether cloud obscures them or not is a different matter.

I see the exact same thing.  And I thought it was only me that saw these !  You can see them outside in bright daylight if you look up at a bright sky for long enough.  They look like myriads of little white flashes moving around in all directions.  I don't think they are caused by an electrical overload in your retinas or optical nerves because I can also see them at normal light levels and even in a completely dark room.  If you stare at one spot for long enough (about 5 to 10 seconds) they will start to appear.   It even works when staring at a white computer screen (it doesn't have to be particularly bright), or even a blank sheet of paper !\n\nI have to say I don't see them unless I look for them, but when I do they are always there.  And, contrary to previous answers, they don't go away after a time, in fact they get stronger if anything.  If I don't blink and stay staring at the same spot for 1 to 2 minutes, eventually my entire field of vision is covered with these lights - they are all I can see until I move my eyes at which point they disappear completely !\n\nThey remind me of the 'static' noise that you see on a TV set that isn't tuned to any station, so they could be due to electrical noise in your optic nerves, or even in the brain itself.  I'm glad it's not only me that sees them, I thought I was starting to lose my eyesight !\n\nIncidentally, there is another phenomena that is similar to this, when you stare at a bright light in a dark room.  This effect looks like a myriad of bright streaks emanating out in straight lines in all directions away from the light source.  More like a halo than worms or static noise.  I think this is definitely something to do with the way your eye functions, but I have never seen any explanation for it.  Has anyone else experienced this ?

It's the same reason stars twinkle--light traveling through the atmosphere gets distorted and flickers.

Here's what they don't teach you in advanced astro-physics:\n\nThey twinkle because they're happy, like when a puppy's tail wags.

Not a simple question, but  this is two main reasons.\n\n1) Brightness of the Star Play a part.   Assume uniform Atmosphere.\n\n2) The Atmosphere also another part.  Assume stars of the same brightness.\n\n1)  Brightness of the Star Play a part.\nBrighter the Star, less likely the twinkle.   Look at the Moon, does it go Bink Bink?  Too Bright.\n\nBut Dimer stars, under the same Atmospheric conditions, may Bink.\n\n2) The Atmosphere also another part.\nThe Atmosphere is not uniform, look at the sky during the day, sometime, it clear blue,  and other time clouds mass abound.\n\nThe Atmosphere is like a thin soup, with some sliver of bread in it,.  using that example, when the Stars of the same brightness is in the Sky,  imagine when a sliver of bread blocks lightly one of the stars, thus one Bink, and another don't.\n\nIt Real life, Stars are not of the same brightness, and the Atmosphere is not always uniform.  making the issue complex.

yes u can see them .go far awy from city where there is vry less artificial light source n enjoy this event at dark night .u can see them moving as though a star is moving . satellite don't flicker.\n\nor see tht in film the octubar sky.
