So when did planets stop having orbits and started having Transits
Makes it sound like an old Ford Van

Getting that close to the sun will cook the brakes for sure.

A black dot moves across the sun.....yawn.

a cool app for those that have kids that like looking at the stars while out camping is skywalk less than 5 bucks

Think the "2012" in the topic title is somewhat redundant... not like the topic would be about the last venus transit, or the next Venus transit ;D
I love the night skies but the Venus transit wasn't that exciting. Have a look at Saturn through a good telescope, far more interesting!

Here are a couple of different ways of looking at a "Black Dot".
NASA | SDO's Ultra-high Definition View of 2012 Venus Transit (https://www.youtube.com/watch?feature=player_embedded&v=4Z9rM8ChTjY)

I could watch that video and find it just as cool without the little black dot moving across the screen. Knowing it's Venus does make it mildly interesting, but watching the activity on the surface of the sun itself in this case is far more interesting.
Cheers!
Jono.

It's an amazing thing the sun, but in comparison
it is a small sun compared to bigger suns that are out there.

I reckon the grapes I had would have been that big, or at least they felt that big :-[ :-[ :-[
FWIW,
I love space stuff, it fascinates me, theres too much of it out there to be empty and uninhabited. Yea life as we dont know it.

Yep, 200,000 galaxies (give or take a few), and the universe is STILL expanding... in fact, the day the universe stops expanding is the day that time itself stops. Or something like that. Don't ask me, I heard Professor Brian Cox (worlds coolest dude) explain it once...

Bill Bryson wrote some interesting stuff on the 1769 transit that scientists measured to work out how far earth was from the sun.
Back then it was a big deal and there was a lot of crazy stuff happening as they sent heaps of explorers/scientists all over the globe to measure it.

Thanks for posting.

We need to remember that Captain Cooks main task for his 1769/70 Voyage was to observe the Transit from Tahiti.
Discovering the Great Southern Land was an afterthought as far as the Admiralty was concerned.
Otherwise, we might be "Bonjour, mon ami" instead of Gday Mate!

Your right it was a close thing. Wasn't there a french ship that lobbed into botany bay a couple of days after cook, tipped their hats and were on their way (then disappeared at sea.

Actually the Dutch first "discovered" Australia (W.A.) quite a few years earlier and named it New Holland. The first documented and undisputed European sighting of and landing on Australia was in March 1606, by the Dutch navigator Willem Janszoon aboard the Duyfken. He mapped Cape York and the Gulf of Carpentaria ... So 'Hallo' it would have been.
Courtesy of Wikipedia:
When Who Ship(s) Where
1606 Willem Janszoon Duyfken Gulf of Carpentaria, Cape York Peninsula (Queensland)
1616 Dirk Hartog Eendracht Shark Bay area, Western Australia
1619 Frederick de Houtman[11] and Jacob d'Edel Dordrecht and Amsterdam Sighted land near Perth, Western Australia
1623 Jan Carstensz[12] Pera and Arnhem Gulf of Carpentaria, Carpentier River
1627 François Thijssen[13] het Gulden Zeepaerdt 1800 km of the South coast (from Cape Leeuwin to Ceduna)
1642–1643 Abel Tasman Heemskerck and Zeehaen Van Diemen's Land, later called Tasmania
1696–1697 Willem de Vlamingh[14] Geelvink, Nyptangh and the Wezeltje Rottnest Island, Swan River, Dirk Hartog Island (Western Australia)
Guess they couldn't populate it with convicts like Britain could as so it's mostly gone un-noticed really. So saying it was "discovered" by Captain Cook in 1770 ... isn't 100%, correctly true, really at all, perhaps, maybe. ;D
