Milky Way may have a huge hidden neighbour....
http://www.newscientist.com/article/mg2 ... hbour.html ^ | August 13th, 2009

A LARGE satellite galaxy may be lurking, hidden from view, next door to our own. Sukanya Chakrabarti and Leo Blitz of the University of California, Berkeley, suspected that the gravity of a nearby galaxy was causing perturbations that have been observed in gas on the fringes of the Milky Way. "We did a large range of simulations where we varied the mass of the perturber and the distance of closest approach," says Chakrabarti. In the best-fitting simulation, the unseen galaxy has about 1 per cent of the Milky Way's mass, or 10 billion times the mass of the sun. That's a lot. It means the object has roughly the same mass as the Milky Way's brightest satellite galaxy, the Large Magellanic Cloud (LMC). Right now, says Chakrabarti, the galaxy is roughly 300,000 light years away from us - about twice as far away as the LMC. But the simulations suggest it follows a highly elongated elliptical path, and about 300 million years ago it swept through our own galaxy just 16,000 light years from the galactic centre - closer in than Earth - disturbing the Milky Way's outskirts as it went.

To make matters worse, the simulations suggest that the galaxy orbits ours in the same plane as our galaxy’s disc. If it is now on the opposite side of the galaxy from us, it could be hiding behind the thick gas and dust in the galactic plane. “It’s very likely to be in a region of very high obscuration,” says Chakrabarti. The work will appear in Monthly Notices of the Royal Astronomical Society.

By further studying the distribution of gas, Chakrabarti hopes to pinpoint the galaxy’s location so that astronomers will know where to look for it. This parallels the way astronomers in the 1840s discovered Neptune from irregularities in the motion of Uranus caused by gravitational tugs from the more distant planet.

If the unseen galaxy exists, it will be the first nearby galaxy detected through its gravity rather than its starlight.

It wouldn't be the Mars bar, would it?

Can you even buy Mars bars anymore? I don't see them in the stores in central VA.

It's impossible to hide a galaxy.

Unless maybe you are hiding it behind the shed out back.

Then, yeah, sure.

They can be bought here in the US, but are much more common in the UK.

Milky Way may have a huge hidden neighbor....

Worse yet scientists reported that this neighboring galaxy played loud music late at night, didn't cut its grass, left its garbage cans out at the curb for several days and left beer cans in the Milkyways front yard. The intergalactic tenants association has been called, but had no comment.

Well, my wish for all FReepers is that the next time this thing comes plowing through the Milky Way galaxy, disturbing everything to which it comes near, that it doesn’t come anywhere near Uranus.

There was a theory floating around I read about recently that the Earth is actually part of a small galaxy or cluster of stars that collided with the Milky Way Galaxy.

And of course, we all know about the Dec 21 2012 theory of our demise based on a perfect alignment of our solar system with the center of the galaxy or some such.

The old U.S. Mars bar, the one with white nougat and almonds, has been re-packaged as Snickers with Almonds, same candy bar.

It's not the same Mars bar sold in the U.K., I understand.

That makes sense, I guess. We have a running family joke, both in VA and in southern calif, that if anyone finds a Mars Bar they should buy one and send it to me. So far no one has so I assumed they didn't make them anymore, at least in the US.

I used to LOVE that Mars bar, it was my favorite, I was so disappointed when I couldn't get them any more. Imagine my surprise when the hub decides to try a Snickers with Almonds awhile ago, he opens the wrapper, takes a bite and I see that white nougat!! Yippee!!

There was a theory floating around I read about recently that the Earth is actually part of a small galaxy or cluster of stars that collided with the Milky Way Galaxy.

Some 250-300 million years ago, there was a mass extinction of dinosaurs and other life on earth. That kind of extinction occurs cyclically on our planet every 250-300 million years. My belief, which I've expressed in the past, is that, every 300 million years or so, out planetary system (including earth, of course), in its orbital path around the galaxy, encounters a dangerous region in our galaxy which disturbs all life on our planet. We will have that encounter again, but, personally, I'm not worried. But, I'll leave a warning note to my great, great, great... great, great, great..... grandchildren.

Thanks for this. I just learned about the Snickers Almond this afternoon on this thread so I'll look for those locally.

But I sure learned a lot about Mars Bars today. LOL!

Ha! Good eye, Ms_Anne_Thrope! Yes that was me on TV on TV. In case others blinked: I was on some video playing on a TV on the counter in a diner in Cold Foot, Alaska. This was aired on an episode of the reality series Ice Road Truckers. What a coincidence!

I once worked at the New England Confectionary Company (NECCO) in Cambridge Mass. A 200 pound metal bin of candy fell off a dolly and onto my big toe.. I recovered quickly and fully. That was many years ago. Rest assured that all is well.

The Milky Way has 12 other satellite galaxies within half a million light years.

The Mars Bar has a new name... Snickers Almond Bar. Roasted almonds, nougat, caramel and milk chocolate in a 1.76 oz candy bar. A box of 24 is $19.99.

Single bars are $1.05 each on the Pack-a-Bag page.

We first saw the Mars Bar in the United States in 1936. It contained nougat and almonds topped with caramel and covered with milk chocolate. It was renamed the Snickers Almond bar in 2000.
