Re: Any astronomy buffs about tongiht (29thAug) ?

A colleague of mine recently bought a new (small) Celestron astro telescope, and it came with a software disc called "First Light" it is absolutely brilliant but, only available with new telescopes I believe, fortunately he loaned me the disc which I copied (shusssh!!) quite the best astronomical software I've ever seen.
I did try to find it on line before copying it without success.

You might like to install the program at http://www.stellarium.org/
(It's also available on Ubuntu etc)...

Re: Any astronomy buffs about tongiht (29thAug) ?

one can hardly miss Jupiter its the largest planet in the solar system
known as the liquid planet its a giant ball of gas and liquid
about 500 million miles away from earth
we have a problem with Jupiter right now
it usually shows off two  dark, slightly reddish bands , or
stripe.
one is in the northern hemisphere , one in the southern
the southern one has disappeared
no its not august fools day
it was there last year, but this time when Jupiter came out from behind the sun
on its yearly orbit it was gone
before you start buying gold  for the approaching apocalypse  or dream of the genesis of the dalek
relax, it has happened before
The last time it happened was 1973
problem though is that no-one is sure why
its a constantly changing planet and i'm glad
some of you were out looking into the night sky gazing as its a wonderful planet to watch
Jupiter is not solid like Earth but as a core which is four times as big
as earth and around that is a thick sea of liquid metallic hydrogen and then
just lots of gas which form surrounding belts , which is what people through their lenses see
the gases include sulphur and phosphorus which form rings around the planet because of very strong winds
just over 300 mph fueled by Jupiter's rapid rotation
its like a hurricane blowing around its surface without buildings to slow it down

if you can wait a few months, Jupiter will be closest to Earth on Sept. 24 .2010, which is when you'll get the best view of it.
Without one of its stripes.
if anyone out there spots Jupiter minus its southern ring could you let me know

Jupiter the lord of solar system
its visible to the naked eye
a day lasts 9.9hours
and takes 11.86 years to orbit  the sun
its electro magnetic radiation makes the planet
act like a strong magnet
any craft approaching its surface would need to have heavy lead protection
as would any traveler visiting the planet and it would be very difficult
for any craft to lift back off the ground after a landing
so a landing on jupiter is just not going to happen hahaha-haha
why ?
simply you wouldn't have a solid surface on which to land or to walk around , its a gas planet
some might say well  we can go through the gas deeper and deeper and land on its core hahaha-ha
you would be crushed by the pressure of jupiters hydrogen atmosphere
could we land by balloon ?
hydrogen gas is the lightest gas so a helium balloon would sink
so what will float in a  cold hydrogen atmosphere?
any one with an A level in chemistry will be able to tell you is
the only thing that would float would be
hot hydrogen
so you would need a hot hydrogen balloon
as we all know innate hydrogen is a tricky thing as the German WWI balloons showed
As for Jupiter's  origin its believed that Jupiter was  a cloud in the galaxy and that it  had the same composition as the Sun
but it collapsed under its own gravity  and some stuff was left behind
that stuff became the planet in that the majority of that stuff became Jupiter
and the rest went into the Sun and then left a couple of tiny leftovers
one of  tiny leftovers   being  Earth
Jupiter's  speeding gasses  attracted light elements and over time grew bigger and bigger in the process
like an oyster creating layers around a grain of sand  to make a pearl
it protects Earth  by(the Frisbee phenomenon)  cleaning some of debris up,  those objects that are  flying in  outer space
flinging some of it out shooting some of it into the Sun where it will be lost forever
that would otherwise land on earth
Jupiter has cleaned out a path where the other planets like Earth and  Venus  could  exist
in peace
So thanks to Jupiter , Earth has a nice environment instead of being pummeled  by rocks and  comets

@A Fox Is Evil...Hey, that stellarium is rather good. Quite simple and intuitive, has a lot of similarities to First Light (I suppose most astro software would have) but technically not as complex as First Light but for quick reference, excellent. Not seen it before.

Re: Any astronomy buffs about tongiht (29thAug) ?

Only problem I've found is that for some reason the default location is Paris (er! France) whilst I can set Watford UK (from the list) it won't remain set as preferred default however many different ways I find to select it, keeps returning to Paris!! There must be a French takeover conspiracy here somewhere....
It's fortunately not difficult to set up the preferred location each time, just annoying to have to do it.
Having been playing around with it for the last couple of hours, I think I prefer it to First Light.
Thanks

First time I set my coordinates, I'm sure I ticked 'Use as default', but it opened up next time with 'Paris' again. Ticked the box again and all OK now.

One of the small annoyances mentioned in a CNET review of the prog was that it runs full screen, so you have to use the Windows key to restore the task bar.
Just realised that pressing F11 overcomes this.

Glad people like it.  Smiley
It comes (in a Linux flavour) as a standard Ubuntu option.
Just click install - and it does!
