Most certainly our ocean. There’s an incomprehensible number of planets out there. All of them with their own characteristics, maybe some of them have their own oceans! Who knows what lies there!

I have to disagree with Nick here, I think given our current technology there has been put much more effort in trying to discover what is it out there in the space rather than completely understand our planets. We are not able to go as deep as we can in the ocean and there are thousands of species discovered every year. Maybe the key to understanding more space could be found in the ocean, who knows!

Depends what you mean by explore. If you mean to have physically gone there, definitely the ocean, as as humans we haven’t gone further than the moon and that is less than 1% of our own solar system. If you mean study wise, I would probably still say the ocean as well. The universe is soo big that it is really hard to get our head around its size. Each one of the lights you see in the sky at night is either a star, like our sun but probably much much bigger possibly with its own planets, or a galaxy that could be upto 400 times the size of our own Milky Way. We have barely explored 1% of our own galaxy in the terms of actually looking at individual stars and planetary systems. There are thought to be 400,000 stars in the Milky Way and only a hand full of these have been looked at closely. For galaxies, there are thought to be up to 2 trillion (2,000,000,000,000) galaxies. So if each of them has the same number of stars as the Milky Way, that is almost a quintillion stars (1,000,000,000,000,000,000). So yeah, we have barely even scratched the surface of space.

That’s a good question because space is HUUUUGE! We haven’t been to the deepest depths of the ocean yet, but we know it has to be finite. Whereas we don’t really know how far space stretches!
For example, we have better maps of the surface of Mars, than we do of the ocean floor. But, if we talk about how much of it we have been to, it will have to be the ocean.
The furthest spacecraft to ever have travelled away from Earth are the Voyagers! They were launched before you and I were born and they are STILL going take a look at what they are up to here: https://voyager.jpl.nasa.gov
We have even seen further than where Voyager 1 & 2 are with telescopes, so technically, we have explored a lot more space! If you go by first hand experience though, I’d have to say Earth as the furthest into space any human has ever travelled is the moon!
