The Hubble Space Telescope has had a peek behind the clouds of frenzied star-birthing supercluster the Tarantula Nebula, the nearest observable laboratory of the kind of star-making that was common in the early Universe. The Hubble mosaic, spanning a width of 600 light-years, of a star factory of more the 800,000 stars being …
How can anyone look at a picture like that, and not want to find some way, some day, to get out there and take a closer look ourselves? I know Einstein's physics says no, but...
Nah, up close it wouldn't look nearly so good.
True - ish. Up close it's as bright as the full moon.
So not quite as spectacular to the naked (alien) eye. But still pretty damn spectacular.
And from that location in the Magellanic Clouds, you'd also see a spiral view of the Milky Way.
How cool would that be?
Pen-y-gors, that's what I thought, too. For example, seeing a spiral galaxy from far away is amazing. Sitting within, well, it's also quite impressive but mostly void. Still, I wonder how such a nebula looks close up if at all.
"I know Einstein's physics says no, but..."
I don't think Einstein's theories ever said no, just that you would need an extremely powerful propulsion system and an awful lot of energy to make the journey within a human lifetime, plus the technology to allow a ship and crew to survive several hundred G's of acceleration / deceleration, potentially for a number decades (so we're not going there any time soon.)
And just as importantly, you'd need a crew who could cope with the knowledge that, due to time dilation, by the time they got there everyone they'd ever known back on earth would have been dead for at least 170,000 years.
But you're right, stunning photo, and wow, what a journey of discovery that would be...
"...by the time they got there everyone they'd ever known back on earth would have been dead for at least 170,000 years."
plus everyone would have forgotten that you'd even gone at all. Monkeys would rule earth by then anyway.
The monkeys already rule earth.
"All I see are the lights of a billion places I'll never go"
If you go to APOD @ nasa you can find a link to a trip to the moon!
> to get out there and take a closer look ourselves?
Not if there are Tarantulas
Hundreds of G? I don't think so. A simple 1G acceleration will get them there in their lifetimes. (Note that in the Earth's reference frame they're already going nearly c in just a year, and from then on it's just a matter of increasing the time dilation factor.)
I can't believe no one's done it already, so...
'MY GOD, ITS FULL OF STARS!'
> How cool would that be?
Quite. No more than a few Kelvin.
That would be a bonus, no?
But by the time people can do this, they would probably be able to keep people alive for much longer time spans. One way of doing that is by flying around the Local Group at reasonable speed and agreeing on meeting up at certain points in time.
Monkeys? We're apes....
An absolutely awesome image from Hubble again. The Tarantula Nebula (seen quite easily with binoculars from the southern hemisphere) is spectacular in its scale, but several other star-forming regions in our galaxy are of course much closer (the Orion Nebula, for example).
And STILL some people believe that the earth was 'created' 6000 years ago.
That sure is some powerful cognitive dissonance.
What is your problem, infidel? Surely, those nebulas et al were created +/- 6000 years ago just like fossils and all was: to appear very old! Thereby proving that earth and things like that were created by a very, very intelligent creator.
Yeah, mine's the one with "Stupidity for Dummies" in its pocket.
Bless. Someone downvoted that comment, presumably because they don't think there really can be people who think that the earth was created 6000 years ago.
But it's true!
Sometimes, truth is stranger than fiction.
The world was created 44 years agon on 1 Jan 1970 - just check your computer's time() function
"These pockets will likely eventually merge into larger clusters, helping researchers to answer questions like whether supermassive stars always form in clusters or whether they can be born in isolation"
Would have thought that it will take millenia before there's any sort of clustering or merging? This'll help researchers in about half a million years, no?
It's called planning ahead.
Or job security.
Ok, I got my coat.
Had the exact same thought when I read that.
And how many light weeks per pixel is it?
Or does the picture look like a big giant flying spaghetti monster?
a power cloud!
"....These pockets will likely eventually merge into larger clusters, helping researchers to answer questions...."
Erm, yes, I suppose so.
But at that time will there be anyone around here to observe it?
Will there be anything here at all?
would just about cover the cost of one pixel for one second. Who Pays for all that stuff to shine so bright and pretty? Is it regulated, government controlled/sponsored? Can I get a copy?
