The asteroid Vesta (mean diameter 530km) is in the southern hemisphere sky, I saw it last night approx 8.30pm from the Byron Bay area unaided. Alt 40, Az 90. Just a fraction south of the eastern cardinal point, climbing vertically. Magnitude is 5.48 so pretty bright, looks like a slow moving satellite. I'll post a Stellarium pic later today.

Jesus!.. i wonder what would happen if that thing decides to poke us... probably modifies the orbit..

it would alter our orbit a bit for sure, but not that much. vesta's mass is about 1/27000 of earth's mass (rough estimation) so we should be okay. the biggest problem would be the huge amount of dust caused by the impact which would change our climate quite drastically.

Post the pictures Mortal. I can't wait to see them. Maybe someone will convert it to Gp4 :)

Modifying the orbit sounds morbid.

I'd prefer if it added us as friends.

I just ain't gonna accept no farmville invitations.

Speed-of-light experiments give baffling result at Cern

[www.bbc.co.uk]

Quote
BBC
Puzzling results from Cern, home of the Large Hadron Collider, have confounded physicists because subatomic particles seem to have beaten the speed of light.

so what does this mean?, every law of physics would be rewritten?... AMAZING!.. i hope it's true.. a lot of people would need to go STFU!...

can you imagine all those mathematicians figuring out some weird formulas throughout all their lives just find out now that it was all a waste of time?

best explanation i heard today: they let undergrads near the experiment :P

we (we=physics nerds) already know that there are problems with relativity. eg it doesn't work on the quantum level. if these findings turn out to be true it would be awesome but for sure we wouldn't have to rewrite anything. just because some neutrinos decided to go faster than light gps devices (which depend on the correctness of relativity) won't stop working.
it would be more or less just another exception where relativity does not work. it came unexpected, though. the scientists who work in this field won't be sad, as there's something new to discover and new ideas will be needed. plus they'll get a lot of funding :-)
the measured deviation was afaik only about 60/1000000 of the speed of light, so this is a very small effect. and in case anyone is interested: here's a preprint version of the corresponding publication: [static.arxiv.org]

The Physics debate is a very interesting one, and it'll be interesting to see what the results are.

Regarding the other major space-related story right now:

It's a surprise to me that they've not been able to keep better track of it.

some news on the faster than light neutrinos (in case you missed it): the people at cern discovered two issues with their experiment. one could have led to an underestimation of the neutrino speed while the other could be responsible for an overestimation. they'll do some more tests to quantify the influence of the problems they discovered.

Perhaps one day all of the leaders of the world will be taken into space, maybe then there will be world peace.
