CCould you guess how many Earths could ftinside a Jupiter(木星)-sized jar? Would youguess one hundred? Five hundred? The answer can be found at the end of this story.Jupiter is the biggest planet in our solar system. All seven of the other planets togetherwouldn't weigh half as much ...
To know how many Earth’s could truly fit inside in three-dimensions, you have to consider total volume, which you can calculate using the simple formula of 4/3 x Pi x radius2. Doing the math, we find that Jupiter has a volume of 1.43 x 1015km³ (1,430 trillion cubic km; 343 ...
we can see with the naked eye. Its claim to fame is that it happens to be the closest one to being straight above the earths northern pole. So like in real estate, the only three reasons we care about Polaris arelocation,locationandlocation. We earth fans have a fickled relationship ...
It is covered here because brown squares and section numbers appears on many topographical maps, and can be confusing if you don’t know what they are. Luckily, UTM and Longitude and Latitude are really the only ones used by wilderness navigators, so you might want to forget I even brought...
After many weeks of a blank sun with no sunspots, a small new sunspot emerged on Sept. 23, 2008, marking a new solar cycle. Photo courtesy of NASA Through telescope images we can see several interesting features on the sun that can have effects here on Earth. Let's take a look ...
We also don't know how many of those planets could have magnetic fields to protect their surfaces from damaging particles, or moons to stabilize their rotation. In short, there are lots of things that make Earth such a special planet, and we do not know enough about planets around other ...
WR: The system must be a ‘many state variable’. Water, H2O, is influenced by a lot of forces and we need to study all those forces to know which variable is influencing the oceans (and water vapour), at what moment and why. We should start with studying all (!) movements in th...
Where will so many people live? How will we feed them?Unless we diffuse this "population bomb", by the end of the century we will need several Earths to survive. But we can't have several Earths, and so we will face a future of increasing poverty, food shortages, conflict and ...
