Are images we see in a telescope snapshot into the past??

Yes, you are completely right.  This is why astronomy is so important.  By looking at galaxies that are a billion light years away, we are seeing what those galaxies looked like a billion years ago.  Since we can see objects up to 13.7 billion light years away (corresponding to the age of the universe), we can see objects like galaxies as they appeared at a range of times, letting us develop more thorough hypotheses about how the universe itself has evolved, and what might lie in our galaxy's future.

We are currently observing 7 objects with a small possibility of hitting us in the near future, and keeping tabs on 14 others that we can't see right now (the sun is in the way).  We also know of 26 objects which we have "lost," but feel that it would be a good idea to find again, just in case.  We also know of another 33 objects that could potentially hit us, but are rather small and would only cause minimal surface damage.\n\nAll in all there are a quite a number of potential impactors right now, we're watching them closly to see if any really will hit us or not.  Obviously this does not count really small things that hit us all the time, just things that are large enough to see in moderate sized telescopes.\n\nJust noticed the source link below mine -- nice to see that Yeomans and Baalke got the JPL site working and up to date again!

Yes, We will be able to see our past. I can explain with a simple example !\nA star situated say 100 light year away from us, this simply means that information of last 100 years about that star is traveling between us and this information is approaching towards us with velocity of light. If we travel towards that star with velocity of light, the rate of information we will receive will be double. In other words we see all things happening there(at star) with double speed.\n    Similarly the photons traveling away from us carrying info. about us will be catched back when we travel faster then light and we will be able to see our past pictures towards the direction opposite from us.\n    Nothing will happen to our physical structure(If we assume that nothing will happen to the molecular chains of our body at that speed), \n We say, at velocity of light the mass of a particle become infinite, that actually means we are not able to push it farther, for example if we push it away by a laser beam that also travel with velocity of light,it will become impossible for a shower of rays to push it farther when the aim is also traveling WIth similar speed. In other words we say it increase of mass with velocity.

Nasa has quite apparently manipulated the light and shadows on the second set of photographs so that the features of the face cannot be properly seen from that angle.  I suggest you investigate these matters on the web.  IMO both the moon, Mars, and Iapetus show signs of ancient ruins of one type or another.  I highly recommend the following site.  Perhaps Iapetus was the Ark that brought us here, Mars was our "Eden", and Earth is where we ended up when paradise was lost.

It is pretty hard for me to say..no they are not real...\nI have seen several things both day and night..A huge object perhaps the size of a football field..it was very massive and overwhelming..I have have witnessed a silver disc object above me in mid afternoon..that shot straight up into the sky with instant speed. Speed that we dont have here. An elongated diamond light at night that turned out to have the intensity of a very bright spotlight...then dimmed again..and shot off up into the sky..with incredible speed ..Orange glowing spheres in early evening...backwards "c" shaped object in the daylight...the list goes on..but..Yeah..I have seen many...I cannot believe other than..We are NOT alone

There have been many systems identified, some with multiple planets and a few with asteroid belts. The problem is that they are mostly discovered by measuring the minute movements of the star caused by gravitational influences of nearby orbiting objects, so most of the discoveries to date have been systems with relatively large planets (many times larger than our Jupiter) and quite close to the star so that the movement is more easily detected. Recently however, there have been more sensitive sensor arrays which have been able to resolve more "normal" configurations using sophisticated imagery, so there is hope for discoveries of systems more similar to our own in the near future. In any event, given the tremendous distances involved, the resolution of optical telescopes available in the foreseeable future would pretty much preclude any traditional photograph of such a system if it were to be found. There have been some rather blurry computer images generated from these other imaging systems, but I'd hardly call them photographs. Try monitoring <space.com>

Yep, check out the Meade Telescope site.  Great new stuff in astronomy.

Wormholes were thought to exist via black holes, like the movie The Black Hole.  That idea was taken back this year so now black holes are just thought to be strong gravitational objects with no special properties.\n\nTime travel was never possible.  The closest thing to seeing the past is by looking at like that was projected by objects.  The light from our sun is around 9 minutes old.

Everything we know about, everything we can see, behaves as if 13.7 billion years ago it was a dense, hot plasma that has been expanding and cooling ever since.  That's the Big Bang theory, and there is a tremendous amount of overlapping, detailed evidence to show that it's correct.  The Big Bang theory being wrong is about as likely, and makes about as much sense, as the idea that a Sun-centered solar system is wrong.  Essentially all of modern astronomy depends on the Big Bang to make sense.  The main observations are:\n\n1) The redshift of more distant galaxies is larger than that of nearby galaxies.\n\n2) Quasars and radio sources are seen to evolve.  There were many quasars in the past, now there are almost none.\n\n3) The amounts of the light elements Deuterium and Hydrogen make sense in the context of neucleosynthesis in the Big Bang.\n\n4) The Cosmic Microwave Backround Radiation is as predicted by the Big Bang theory, both in magnitude and in the details of its anisotropy in amplitude and polarization.\n\n5) All stars and galaxies evolve as if that evolution were set into motion by the Big Bang.\n\n\nYour notion of mirages and crests makes no sense in the context of modern physics.  We do see some warpage of space, particularly gravitational lensing by clusters of galaxies, but the Cosmic Microwave Background is most certainly only 400,000 lightyears from our event horizon.\n\nMany current versions of the Big Bang involve a Universe that exists eternally in both the past and future.  Our Big Bang was not necessarily the beginning of the Universe.

The satellite images on Google earth are not live.\nThey are static (taken months, usually years, ago)

The nearest star in the night skyis 4.3 light years away from us. This means that the light you see started out over 4 years ago. So, in that sense, the image is 4 years old. Stars that are farther away have correspondingly older images. The farthest we can see without a telescope is the Andromeda Spiral galaxy which is 2 million light years away. The light from this galaxy started out 2 million years ago! So, we are lookingback in time 2 million years when we see it.\n\nThis isn't unusual, though. When you hear something, you are hearing it as it was rather than how it is. Just imagine an airplane in the sky. The place where the sound comes from won't be where you see the plane. Similarly, you don't hear thunder until the sound gets to you from the lightning strike. So you are hearing it as it was, not as it is. The only difference is that stars are far enough away that the light takes years rather than seconds to travel the distance.

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.

Given enough imagination, you can explain almost anything with a sufficiently large dataset to draw on: see Slutzsky's Theorem and think about it in terms of things outside time series analysis...\n\nHaving said THAT, the theory has been advanced that these sightings actually could fall into numerous types of categories; some are quite probably purely psychological phenomona, others are probably illusions or misperceptions; some may well be a cockeyed chain of events that are (individually) quite mundane but which are bizarre as a chain--field effects and the like.\n\nWhat I have heard suggested by serious, rather free-thinking but otherwise hard-nosed physicists is that there may be the temporal equivalent of a wormhole: something that will transmit light across large spans of time, but little else, other than (perhaps) other fields and possibly pressure waves (=sound).  Do I buy that?  No--nor do I reject it out of hand, either.  HOWEVER, it is interesting to note that spectral appearances are invariably from the past, and often from the distant (but not too distant) past.  We're talking years to a few centuries, rarely if ever millenia, and I've never heard of a ghost CroMagnon or Astralopithicus or even Homo erectus or whatever.  This suggests that there is a distancing issue--you can only jump so far forward, so to speak, or the perception can only be so long delayed.\n\nThis thought is potentially one that is experimentally testable, actually--or at least potentially so.  Consider this thought: if there is something equivalent to a wormhole or quantum tunneling through time, it is reasonable to assume that the larger the distance in time "traveled" the more blurred the image is likely to be.  THUS, you can set up a "grid" of observations that allow you to rate how "clear" an apparation is--things like number of facial features clearly present, whether clothing is present, whether audible and discrete phonemes are heard in any sound made (you might want to go for just consonants; they's likely be disappearing before vowels, and that gets you past most barriers caused by languages differing); and you can set up some sort of tool (how, I don't know) to allow you to rate the probable age of the appearance.  That would probably need some sort of something to identify the period of the spectre--like period clothing, perhaps, which would require a fairly clear apparition, or the legend of who the spectre is supposed to be, and from when--but I leave that detail to you, because you've probably more data to sift and can find more in terms of datable stuff than I can dredge up out of my ol' brain.\n\nThe null hypothesis: there is no relationship between clarity of apparition and putative age of its source.\n\nActive hypothesis: the older the putative age of an apparition's source, the less distinct it is likely to be.\n\n\n\nJust remember: don't expect a single explanation to handle it all, because the odds are that there are multiple phenomona all being lumped together as "ghosts" or "hauntings"...

My first answer is probably not, because we would see future people by now.\n\nHowever, what if UFO's are time machines from the future?

The photos are as real as the stars in the sky \nWhatever see in the sky is the past ,all these have been found to obey a gravitational theory proposed by einstein,many experiments conducted on earth also validate the theory ,So if u have the belief in the theory then believe what u see

yes. i don't think any pre-existing celestial body can be reflective like that, but if there somehow were one far enough away, then yes.  it would have to be very very far though. for example, if it were 2 light years away, then we would see events from four years ago, the light would have to travel 2 years there and 2 years back. but we would see the events being exactly played out, in real time, and always exactly four years ago, and it would follow the rotation of the earth, so it would only be certain parts at certain times.

What you have stated is quite true only that inorder to view what happened at thatime you will have to have like a super tellescope mciroscope (if theres any thing by it) inorder to view what happened here at that time time "x" It is not hypotheticaly possible it is possible by all laws the only thing is that currently we do not have that kind of technology.
