it's actually Ceres, proto-planet in the asteroid belt.

 

mercury, venus, earth-moon, mars, ceres

Does this include Jupiter and Saturn? Apparently, they're much larger than earth (10 & 9 times)...

cool

haha yeah, would not fit in picture.

if we crashed two jupiters into each other it would probably create a star

 
 

i guess you need more than that

In terms of mass, you'd need to pile up 75 jupiters to start fusion.

However, in terms of diameter, some of the smallest stars are only 30% bigger than Jupiter. This is because, as you add mass, gravity also becomes stronger, so the whole thing just gets more compressed, instead of more swollen.

And that's the key. All that extra mass is compressed a lot in a star, which eventually kickstarts fusion.

really cool orbital game

perfect for this forum

Those giant energy bubbles look an awful lot like electron clouds around atoms. 

space programs like nasa are bloated innefficent government bueracracies with little performance based incentives or goals.


Fair enough, however, I don't think it's accurate to blame NASA for this. You can't be redirected from "Go to the Moon" to "do some stuff" and not be unproductive for a time. 

I'd agree that there's way too much focus on "process" sometimes though. 

Not too long ago NASA had a large performance-contract based push. The downside is it eats away at the very thing NASA is good at: taking huge risks that might not have good return on investment. People quickly abandoned projects that weren't "sure, quick wins," and we lost some interesting technology development. 

Expensive space experiments have always been at the core of NASA. The science required to innovate in the fields of cosmology, astronomy, and space exploration necessitate some level of experimentation done beyond the grips of this planet. 

"The Universe in a Nutshell," also by Hawking, is outstanding as well. 

I'll buy that with the giant diamond in the core of Jupiter.

It's been theorized before that since renditions of atoms look similar to celestial masses that solar systems are in fact atoms in a molecule, that we are in fact part of an actual larger bit of matter that we don't have the ability to detect.

another great pic to destroy 56k modems

wow, this is great.

It's a little bit anal on the data but some if it for me is interesting so to the ones that did not see it and like this type of info .
