What are stellar nurseries?

http://en.wikipedia.org/wiki/Molecular_cloud

A molecular cloud, sometimes called a stellar nursery if star formation is occurring within, is a type of interstellar cloud whose density and size permits the formation of molecules, most commonly molecular hydrogen (H2). This is in contrast to other areas of the interstellar medium that contain predominately ionized gas.

Molecular hydrogen is difficult to detect by infrared and radio observations, so the molecule most often used to determine the presence of H2 is CO (carbon monoxide). The ratio between CO luminosity and H2mass is thought to be constant, although there are reasons to doubt this assumption in observations of some other galaxies.[1]

Here's a picture I took of one yesterday:

Do we have the technology and capability to land on Mars the way we did with the moon?

With the technology we have now, if we sent men to Mars, it would pretty much be a one way trip. We do have Mars rovers there now, scootling about at an interminably slow speed, taking samples, taking photos and acting the c**t. The Mars rover has it's own twitter feed, which is quite good.

Great post once more confi. I enjoy reading about all these things, but clearly not as much as you. If you could post or pm any good links i would be gratefull.

Of course my fine fellow:

Also, to have your breath quite literally taken away, get your arse onto Wikipedia and read up on the following cosmic wonders:

Quasars, Gamma Ray Bursts, Hot Jupiters, Pulsars, Magnetars, Neutron Stars, Exotic Stars, Blasars, Red Supergiants.

That should keep you busy.

You can fit about 1400 Earths inside Jupiter. So if the big fella made Earth in 7 days, it would take almost 27 years to get Jupiter up and running.

correct me if i'm wrong, but isn't Jupiter just a great big ball made up of the same stuff? even though its huge, the old boy should have been able to knock it up in an afternoon surely

Jupiter's an interesting big b*****d.

It's mass is a thousandth of the Sun's mass, but two and a half times that of all the other planets in the solar system put together.

As for what it's made of, it's mainly hydrogen, about a quarter helium, in gas and liquid form,possibly has a rocky core and has no solid surface at all. It's ALL atmosphere.

" The density of the interior of a magnetar is such that a thimble full of its substance would have a mass of over 100 million tons."

What's the chat with that, then? How is that possible, and how do they know that for sure?

Same with neutron stars. They're basically the corpses of stars after they've went supernova. The density is because of the sheer mass of the thing and the small space it's squeezed into. A neutron star that has the same mass of one and a half times that of our Sun would be between 10 and 15 km in diameter, which is about 1/60,000th of the Sun's diameter.

As I said earlier in the thread, a teaspoon of this stuff would weigh around 900 times as much as the Great Pyramid of Giza.

This is why I fucking love Space!

The fact we can't even confirm for sure how many moons Jupiter has shows how much we really know about the universe, 63 is known at the moment.

Jupiters europa moon may support life as it is believed that it has the most vital thing to support life, water. Would be incredible.

Europa is basically just a giant ocean underneath a big thick ice sheet.

Could be all sorts down there.
