How Much Of Space Have We Explored

In space we can see out great distances and using powerful telescopes scientists can make discoveries about the vast universe around our solar systems.
How much of space have we explored. It is said that humans have managed to explore only about 5 of the ocean floor. It would take the space shuttle seven months to fly there. We are peripherally located in one of those galaxies known as the milky way. Did mars provide similar environmental conditions for life long ago.
Mercury has been a difficult planet to explore as spacecrafts have to withstand high temperatures being so much closer to the sun. Soho esa nasa when we leave the solar system we find our star and its planets are just one small part of the milky way. Part of this could also be attributed to history. Astronomers have discovered a gas giant planet that s roughly 13 000 light years from earth among the furthest ever known and yet there s still so much more to find.
Cosmic evolution is depicted in this image from the exobiology program at nasa ames research center 1986. That s why the sun which is a million times the size of the earth looks so small. Astronomers today have seen objects 13 billion light years away in a universe 13 7 billion years old containing hundreds of billions of galaxies. Evidence from mars missions suggest mars may have been much warmer and wetter than we observe it to be today.
Space exploration is much newer yet it seems scientists have made more progress. Even though humans have explored and mapped large parts of the planet mars and the moon in outer space only a small part of the oceans of the world have been explored till now. Our sun the nearest star is 93 million miles away. Given the millions of asteroids in the asteroid belt this region is currently under explored.
How much of space have we explored. In this ancient timeframe scientists find the first evidence of microbial life on earth. The remaining 95 of the ocean still remains a mystery. That s made up of planets stars and galaxies that astronomers can see.
To date scientists have explored about 4 percent of the visible universe.
