Is it possible that an object no longer exists even though it is visible through high powered telescopes?

Yes. I assume you are talking about objects that are very far away from Earth. Let's say we're talking about an object 10,000 light years distant. IF we can see it, what we are actually seeing is the object as it appeared 10,000 years ago. That's how long it takes for the light emitted from or reflected off of the object to reach our eyes here on Earth. It makes no difference that we are looking through a high-powered telescope. The speed of light is unchanged. The only "power" involved is an increase in our ability to see that light that is just now reaching Earth. Our high powered telescopes do not have the power to go out and grab that light immediately from the object 10,000 light years away and transport it instantaneously to our eyes. That kind of power does not exist and probably never will.
It is, of course, entirely possible that the object in question was destroyed some time in the last 10,000 years, and therefore no longer exists. We still see it only because, 10,000 years ago, it was still emitting or reflecting light, light that is just now reaching us. 10,000 years after its destruction, we will see that destruction. But until then, we will see the object in all its intact splendor.

What are the largest telescopes used for observations in the visible region of the spectrum?
The largest telescopes that use visible light are reflector telescopes.
What are the largest telescopes used for observations in the visible region of the spectrum called?
The largest telescopes that use visible light are reflector telescopes.
What kinds of telescopes are used to see stars in visible light?
Optical telescopes.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How long was the crab nebula visible for?
The Crab Nebula or SN1054 is still visible with telescopes.
Why are radio telescopes not located on top of mountains like the visible light telescopes?
It is not necessary to do so, as atmosphere doesn't distort radio signals as much as visible light.
Does makemake appear in the sky?
Makemake is not visible to the naked eye, or even to very large telescopes. It is barely detectable only through a detailed computer analysis using the most powerful telescopes in the world, or in space.
What telescope does not use visual light energy?
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
What are light telescopes?
Telescopes that work with visible light, as opposed to other radiations such as infrared, ultraviolet, x-rays, etc.
How do telescopes for invisible wavelengths differ from those for visible light?
Visible Light telescopes use mirrors or lenses. The images are viewed by the naked eye. Telescopes operating in invisible wavelengths use Electromagnetic sensors. The data is then converted into an image that can be viewed by us.
What is the observable parts in the milky way in terms of light years?
Most to all of the milky way is visible through sattelite telescopes as well as other galaxies, but only our local spiral arm is visible from here.
What part of the electromagnetic spectrum do MOST telescopes use?
Visible light
