How Much Of Space Have We Explored

Space exploration is much newer yet it seems scientists have made more progress.

How much of space have we explored. Our sun the nearest star is 93 million miles away. Cosmic evolution is depicted in this image from the exobiology program at nasa ames research center 1986. 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. In space we can see out great distances and using powerful telescopes scientists can make discoveries about the vast universe around our solar systems. 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.

Part of this could also be attributed to history. 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. Astronomers today have seen objects 13 billion light years away in a universe 13 7 billion years old containing hundreds of billions of galaxies.

Did mars provide similar environmental conditions for life long ago. We have two asteroid sample return missions being planned. It is said that humans have managed to explore only about 5 of the ocean floor.

The remaining 95 of the ocean still remains a mystery. 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. Given the millions of asteroids in the asteroid belt this region is currently under explored.

That s why the sun which is a million times the size of the earth looks so small. It would take the space shuttle seven months to fly there. Although many scientists do believe that there s much more of the universe to explore comparing 13 billion lightyears to the ocean only being seven miles deep underscores how much technology has developed for space exploration rather than ocean exploration.
