Hey guys;
I was just reading this post: http://www.minecraftaddicts.com/showthread.php/11589-SCIENCE!
And Yen said he would love a topic about about space... So here it is : Most Interesting Thing You Learned About Space Today :)

Also if you don't have anything to say about space DON'T POST!

I'll start... The most interesting thing I learned about space today is that billions of light years away there are Earth sized planets that could possibly have life on them, In particular a planet that is 100% water. This 100% water planet may not seem special but it would be like and ocean on our own home planet... Life forms like like plankton or bacteria living in it.

Lifting a toothpick on a neutron star would be like benching something like 2.8 m tons
 
In order to make a black hole from all the mass of the earth (the gravitation will be so strong so light can't escape it) the whole earth will have to shrink to be smaller then the period at the end of this sentence (So whilst keeping all the mass of the earth).
Also black holes are other stars or planets that have done this, and this doesn't happen slowly but in a matter of seconds.
And time is really bent in black holes.
 
Space is so far and few between...

however this small snippet always makes me think.... those planets we see now may be where we are or more advanced... they may even be completely destroyed from war... and we just cant see the destruction on their surfaces yet.

 
Heh good ol' Cracked, thanks a bunch for kicking the thread off btw Cheezy, anyway, for some reason I've always found Jupiter's moon Europa to be pretty interesting, apparently it contains more water (albeit frozen on the surface) than Earth, it's also one of the better prospects for extra-terrestrial life in the solar system.

Also, Curiosity might have an interesting find (nothing actually announced as of yet as they await confirmation). Source.
 
The energy in the sunlight we see today started out in the core of the Sun 30,000 years ago – it spent most of this time passing through the dense atoms that make the sun and just 8 minutes to reach us once it had left the Sun!
 
Oh, and our sun and solar system is a 2nd generation item. That means kiddies, you are made from stardust, an Ex-star provided the matter from which we were moulded/formed/created/shaped.... whatever. So when you think on it, the sun really does shine out of our arses!
 
The only 'fully' illustrated and rendered planet apart from earth on orbiter (It's in the UCGO simulation which is downloadable) is Europa. It has about a 1 km x 1 km spot that actually looks half decent.

And now to a more real world application of this thread

It was just a tiny galaxy, minding its own business shortly after the big bang. But a chance alignment has brought this ancient galaxy into view. It just might be the most distant object that astronomers have ever seen.

A new study using the Hubble and Spitzer space telescopes has tentatively identified the galaxy, so far away that its light has traveled for 13.3 billion years to reach us.

The galaxy itself is no shining cosmic beacon. In fact it’s only about one one-hundredth the size of the Milky Way. So how did the scopes see it? Chalk it up to a cosmic conjunction.

Some 5.6 billion years ago, its light passed a giant cluster of galaxies. The gravitational pull of the galaxy cluster acted like a lens. As a result, the scopes saw the tiny, distant galaxy in distorted—but greatly magnified—form. The study will appear in The Astrophysical Journal. [Dan Coe et al., CLASH: Three Strongly Lensed Images of a Candidate z ~ 11 Galaxy]

In the cosmologist’s preferred distance measure of redshift, which gauges how much light has been stretched in an expanding universe, the galaxy lies at a redshift of about 10.7. The previous record holder was found at about redshift 10. Literally far out.
 
In 2015 a company in Ohio is launching a test-unmanned space craft, testing a new, safer space fuel.
 
Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion Suns — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories of how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.

NGC 1277 lies 220 million light-years away in the constellation Perseus. The galaxy is only ten percent the size and mass of our own Milky Way. Despite NGC 1277's diminutive size, the black hole at its heart is more than 11 times as wide as Neptune's orbit around the Sun.
 
I guess this fits here:

Super high resolution view of the earth at night! We are starting to look like something out of a scifi movie!

From what we know about the physical world, our consciousness cannot exist without something else outside. I just picture a big server room with all of our thoughts contained in them. And the admin will occasionally turn it all off and we would never know it happened!
