We have not physically explored our galaxy beyond the bounds of our own solar system, because we lack the technology to do so. We have still been able to learn a great deal through sending out space probes and through the use of powerful telescopes such as the Hubble.

∙ 14y agoVirtually nothing has been explored. Even if we had our entire solar system well mapped, we would not have any portion of this really giant universe explored. Even the Milky way is a very very tiny portion of this really giant universe!

∙ 13y agoIt depends on what you mean by explore. Satellites have photographed the entirety of the surface, including the oceans. If you mean explored by a human actually going there and observing the place and its intricacies, the ocean, caves, rain forests, and unpopulated forested mountains like in Alaska and northern Canada, are largely unexplored. If you follow roads on Google maps you can see huge areas of rough unpopulated areas that are unlikely to have had any real in depth exploration.

We have only now started to see the edge of Our system that circles our sun,
the Solar System is just a small smudge on the Universe to explore.
That (this) is hard to answer because it depends on what you mean by 'explored'.
The human race has photo's from space of pretty much every square inch of this planet, but that does not mean that a human has actually been there; and that does not include the oceans (whats under the surface; seems as though we discover new things there every day) - so you can only really say we have a very good ideal of what 1/3 of this planet is like.
We (the human race) have only went to one other planetoid (the moon) and while we have satellite mapped it, we have only actually walked on a few hundred square feet of it.
Following this guideline the human race has sent probes to, and observed all significant astronomical bodies in this solar system. We have sent probes to map, photograph, and take other readings of pretty much all of them. This gives us a very good ideal of the overall layout of things, but we are far from finishing with this planet and it will be hundreds of generations (at current rate) before we have made a dent in exploring even our closest two neighboring planets.

When was the star polaris discovered?
Polaris has been there all along. The ancient Phoenician and Chinese astronomers knew about it, and the Phoenicians used for navigation. (Not that it did them all that much good, since ancient ships were difficult to keep on track; the ships went where the wind did.)
What is the name for the periods of time where the Earth has been much colder?
The periods of time where the temperature of the Earth has been much colder then traditional times are referred to as ice ages. It is a long term reduction in the temperature of the Earth resulting in the expansion of the polar ice caps.
Who has tried discover Pluto?

How much water does the earth get every year?
None. The water cycle only recycles the water that has been on Earth for the past 13 billion years.
When was proxima centauri discovered?
There isn't much to "discover" here - Alpha Centauri is the third-brightest star in the sky. People must already have seen him tens of thousands of years ago.
How much of the earth's land surface is undiscovered?
All the earth's land surface has been discovered. There are parts that are virtually unexplored, however.
How much percentage is the earth is it 100?
Only if you are referring to earth as a percentage of earth, then earth is 100% of earth
What has been discovered about earth the moon and the solar system by visiting the moon?
What was discovered was that the moon is composed of material that is very close to the composition of the outer layers of the earth. A theory has been adopted that the earth was struck by a small proto-planet, about the size of Mars, and the collision threw much of the earth's crust into orbit, that eventually formed the moon.
Have scientists discovered a planet comparable to earth?
Comparable, in what sense? - Scientists have discovered over a thousand planets outside our Solar System; most of these are much larger than Earth (since those are easier to discover), but several have been found that have a mass comoparable to Earth.
How much percentage of water is in earth?
78 %
Is there an earth like planet the size of earth's moon?
No planets like Earth of any size have been discovered. For a planet the size of the Moon to have Earth like characteristics, it would have to have a much larger iron core in order to hold on to an atmosphere.
How much percentage is the desert covering on earth?
About 33% of the land surface of the earth is desert.
How much percentage of deforestation is on the earth?
More than half.
How much percentage of the earth is covered by the hydrosphere?
75% or 3/4 of the earth is covered by hydrosphere
By whom was the sun discovered?
Uhm, the first living being on earth, the sun is much older than the earth.
How much percentage of beryllium makes up the earth?
The beryllium abundance in the earth's crust is 4-6 ppm.
About how much percentage of the earth is in a temperate climate?
About 45% is covered in a temperate climate
