Can the naked eye see into outer space.?
Answers:
Oh Yes! Just look up.
The Astronomer Fred Hoyle had a great line; Outer space is not that far away. You could drive there in less than an hour.
If you could drive your car straight up, of course. But Space begins where our atmosphere stops, it's that close! (In fact, it could be argued that some of the earliest 'space flights' never really left the atmosphere, but that's being pedantic!
To answer the detail part of your question - yes, you are indeed seeing the light generated (not shining off, that implies relfection) by the stars - which is why looking into the sky at night is looking into a time machine! The light hitting the retina of your eye left the star year ago - sometimes hundreds or thousands of years ago. The star itself may well no longer exist. Amazin, aint it?
only as far as the eye can see!
yes it can, not very deep though
yes thats what the black stuff is
You are seeing the light that is traveling at the speed of light towards the earth. You are not seeing the stars themselves. Or, you are not seeing the stars in real time. Can the naked eye see into outter space ? .. Yes.. but not very far and not very well.
Yes, just open the window!
you are seeing the light that they gave off thousands of years ago. it takes a long time to get here.
I have not seen it yet, but I'll keep an eye out for it
We have a great article on that here at the observatory written by one of the fellow astronomers I work with .. it's a little long but I think you'll enjoy it !
Our Tiny Universe: What's Really Visible at Night
On a clear dark night away from city lights, the star-spangled heavens can create an overwhelming sense of infinity. Seemingly countless points of light, so far away, urge one to contemplate the insignificance of a lone planet amid the incomprehensible breadth of the universe.
we see very little outside our own backyard, a tiny neighborhood of our galaxy where the Sun is common, just another three-bed, two-bath star in the suburbs of the Milky Way.
Almost all of the sky objects visible to the naked eye are stars that reside in our galaxy. In fact the bulk of those you can see are relatively nearby, within a few thousand light-years. Most are actually within a few hundred light-years, with the exception of a few intrinsically brilliant stars that are many thousands of times more luminous than the Sun.
For comparison, the Sun is about 26,000 light-years from the galactic center, orbiting on an outer spiral arm. The galaxy itself is about 100,000 light-years wide. We see most of its contents only with powerful telescopes working at various wavelengths of light not visible to humans.
A light-year is the distance light travels in one year, racing at a speed of 186,000 miles per second. It's equal to about 5.88 trillion miles, or 9.46 trillion kilometers.
On a clear, dark night in the countryside at the right time of year, you can actually see the milky swath that gives our galaxy its name. It is a fuzzy region of the sky that represents the millions upon millions of stars toward the central disk of the galaxy, where the bulk of the Milky Way's stars are huddled in a bulge around a central black hole.
Seeing the Milky Way's main disk from our perspective is akin to standing near the edge of a cornfield, poking your head up, and trying to see the middle of the field during a thick ground fog.
Counting down
There are roughly 300 billion stars in the Milky Way.
At most, 8,479 of them are visible from Earth to someone with perfect vision under ideal conditions. Not all these stars can be seen from any one location, of course. You miss about half of them by not travelling to the Southern Hemisphere, for example. The horizon, as well as the seasons, place further limits. Roughly 2,500 stars are available to the unaided eye in ideal conditions from a single spot at a given time.
Light pollution in cities and suburbs throttles the number down dramatically. In New York, for example, as few as two dozen stars dot the dome of night.
Clear and dark skies reveal a handful of nearby galaxies, but each is on the fringe of naked-eye visibility. The most obvious and celebrated is the Andromeda Galaxy, which is the closest large galaxy to the Milky Way.
At 2.5 million light-years away, Andromeda is markedly more distant than all visible stars.
"The light you are now seeing is around 25,000 centuries old and began its journey around the time of the dawn of human consciousness," says Joe Rao, SPACE.com's Night Sky columnist. "When it began its nearly 15-quintillion-mile journey earthward, mastodons and saber-toothed tigers roamed over much of pre-ice-age North America and prehistoric man struggled for existence in what is now the Olduvai Gorge of East Africa."
No one can see the individual stars of another galaxy without a big telescope.
The brightest 'stars'
As light pollution renders the sky less interesting, some objects become all the more prominent. Some of the brightest "stars" in the sky are planets. Venus, Mars, Jupiter and Saturn routinely rival or outshine the brightest stars, depending on where they are on their orbits around the Sun in relation to the position of Earth.
Venus can be so brilliant that concerned citizens call their local law enforcement offices to ask what's up.
And of course the Moon is obvious when it is up. Several Earth-orbiting satellites are also visible at night, including the International Space Station.
And finally, since we're counting, there's one more celestial object to mention, one that is visible in broad daylight. It is the brightest star in the sky. Our Sun, of course.
Stars are supposed to be billions of light years away so i guess its just the light you can see shining off them yeah.
can you see the milky way?
can you gaze at the constelation orion..the answer is
dun dun daahhhhn..
YYYYEEESSS
When you look into the sky at night, you are looking into space. You are also looking back in time, as the light that you are seeing takes thousands of years to travel from the stars to your eyes.
When you look at anything all you actually see is the light that is either reflected from it or generated by it. So, yes, you are seeing the light from stars many, many light years away.
Yes.
You can see a few of the planets with the naked eye, Saturn is particularly impressive.
What you are seeing is the light boucing off (but that's true of a lot of things you see), and light that's been travelling many, many light years to reach you.
Isn't it fantastic!
With a small telescope you can even see Saturn's rings!
You are looking at the light shining from stars. Whereas, our local planets and moon are illuminated by our sun as is planet earth.

Ahhh, my eyes!
Yes.
they are not stars you have got pinholes in your eye lids
open wide your eyes and you'll see .. the light that surround you. it's magical isn't it ?
When you look at anything what is actually happening is the light is traveling from the object right into your eye and striking light detectors in your eyes called rods (and cones for color).
All light headed in our direction, assuming it isn't intercepted by anything and can make it here before we expand out of it's reach, actually does make it here, whether you can see it or not. The eye is not sensitive enough to detect a lot of though it may be in the visible part of the spectrum and thus when these low amplitude photons enter our eye they go undetected by us. Light "spreads out" the farther it gets from the source. Kind of like an expanding shell, and thus becomes dimmer.
Telescopes work by collecting up this light and "condensing" it to make it bright enough for your eye to detect.
So you actually aren't doing anything more than pointing your eyes and letting the light flow in.
Seeing something is exactly the same thing as seeing the light coming from that thing. In the case of stars, the light is coming from inside the star. This is true of lightbulbs as well---when you see a light bulb that is turned on, you see it in the light it generates. When you turn the light bulb off, you see it in reflected light. When you see the planets or the moon, you see them in reflected light from the Sun. When you look at the Sun, you see it in the light it is emitting. The stars are the same as the Sun, only further away.
The Sun, the planets, and the stars are all in "outer space", so yes, when you see them you are seeing into outer space.
If you can see the stars then you are looking into outer space. Everything that you can see, your computer for example, you can see either because it has light shining from it or light is being reflected from it; so yes, you are actually looking at stars.
Yes the naked eye can see into space! But the light that you see from the stars are actually millions of years old because the light from the star is still traveling.
Yes, looking into the night sky you are looking into space, and, amazingly, back in time. Light travels at phenomenal speed(186,000 miles per second) and astronomers measure the distance to stars in light years(1 light year is light from a star that has taken a year to reach us). So for a star that is 100 light years away from us, we are seeing it as it was 100 years ago. If you see something that looks like a fuzzy patch, it could be a galaxy, and some of these galaxies are so big they would make the Milky Way look puny.
Even looking at our local star, the Sun, it's 93million miles from us so it's light takes EIGHT minutes to reach us. The moon's light take just a few seconds.
no those are real stars. Actually, you can see about 2 million light years or so with your naked eye if the object is large enough. And because it takes several years for light to travel to us, we can view stars that are dead right now sometimes.
When you look into the night sky you see the stars but because there so far away on average 40 billion light years you see them how they looked 40 billion years ago. (when you see the sun that's how it looked 8 minutes ago freaky huh?)
