Living beings which have eyes can observe light. Nature has endowed the human eye with the sensitivity to detect electromagnetic waves within a small range of electromagnetic spectrum.
Object that only shine with radio waves and not in the visible spectrum an object hidden by dust that block visible light.
You can observe an object's color, shape, texture, size, weight, smell, taste, and temperature using your senses.
Yes. A comet is a real object that you can observe.
That would be the current distance. It emitted the light 13 billion years ago, when it was much closer; in the meantime, it moved away from us.________________If it emitted the light we observe 13 billion years ago, then by definition the object we observe is 13 billion light years away. We have no way at all of observing what might be the object's true current location or distance. If the object still exists, it is completely beyond our relativistic frame of reference. Think of it this way. The actual events within the sun at this very moment are completely outside of our relativistic frame of reference. If the sun has exploded right in this very moment, we have no way of knowing anything at all about the event until about 8.5 minutes from now.The answer might have to do with the expansion of space itself, which is different from what we would think of as objects simply moving away from one another. The theory that many hold is that there was an extremely rapid expansion very early on after the onset of the universal expansion (big bang), much more rapid than we usually consider possible given the speed of light as the limit.
We observe the universe with our various telescopes. Since light travels at a finite speed, it takes time for any light to travel from an object (say, a galaxy), to your telescope. Therefore, for any distant object, you are not seeing the object as it appears now, but as it appeared when the light left it.For very distant objects this can be billions of years, and further back in time you look, the more different the universe appears. Beyond about 13 billion years, there are no galaxies, for example.
The wavelength of light used to observe an object must be shorter than the size of the object itself.
Object that only shine with radio waves and not in the visible spectrum an object hidden by dust that block visible light.
A flower is an object that you can observe using your nose, as it emits fragrances that can be smelled.
You can observe the color, texture, shape, and temperature of an object using your senses.
[object Object]
You can observe an object's size, shape, color, texture, weight, and any other physical characteristics it may have.

You would use a compound microscope with transmitted illumination or a digital microscope with top lighting. These microscopes can illuminate the object from above, allowing you to observe details even if the object is too thick to let light pass through it.
You can observe an object's color, shape, texture, size, weight, smell, taste, and temperature using your senses.
The farthest objects we can observe are galaxies that are around 13.8 billion light-years away. This distance is governed by the age of the universe, as light from these objects has taken the entire history of the universe to reach us.
