This was one of aol's stories today that I found interesting. Since it was an aol link, I found another artical to post at the end. (May 16) - Astronomers are baffled after finding an exotic type of star called a pulsar apparently locked in an elongated orbit around a star much like the sun -- an arrangement defying what had been known about such objects. The rapidly spinning pulsar -- an extraordinarily dense object created when a massive star exploded as a supernova -- is called J1903+0327 and is located about 21,000 light years from Earth, the astronomers said. A light year is about 6 trillion miles, the distance light travels in a year. "The big question is -- how in the heck did this thing form, because it doesn't follow our standard models of how these things form," astronomer Scott Ransom of the National Radio Astronomy Observatory in Charlottesville, Virginia, said in a telephone interview on Thursday. This object is known as a millisecond pulsar because of its speedy whirl -- it spins on its axis 465 times per second. "The reason why we're so excited about this is the impact it might have on our understanding of where the pulsars that we look at are coming from," David Champion, an astronomer at Canada's McGill University, told SPACE.com. "We've never seen anything like this before." Until now, all of the ones found orbiting with another star have been doing so with a white dwarf, another type of dying star. In each case, they shared a perfectly circular orbit. But this one has a very elongated orbit around a star similar in size and composition to our sun. "What we have found is a millisecond pulsar that is in the wrong kind of orbit around what appears to be the wrong kind of star," astronomer David Champion of the Australia Telescope National Facility said in a statement. "Now we have to figure out how this strange system was produced." It was detected using a radio telescope in Puerto Rico. Pulsars are a rare type of neutron star whose strong magnetic fields channel lighthouse-like beams of light and radio waves that whirl around as the star spins. Typical pulsars spin once a second to about 10 or 20 times a second. But millisecond pulsars spin far more rapidly. The understanding had been that these started out as typical, slower-spinning pulsars, then built up speed after material expelled from another star reached the pulsar's surface, giving it momentum. "If you were to ask any astronomer if we would have found a system like this, they would have said no. So this is a very big surprise," Ransom said. The scientists, writing in the journal Science, speculate a third star -- perhaps a neutron star or white dwarf -- might be orbiting with the other two. Scientists know of about 100 pulsars in two-star, or binary, systems, and this might be the first in a triple-star system, Ransom said. here is another artical about this star system: http://www.space.com/scienceastronomy/080515-weird-pulsar.html I just love learning about the wonders of the universe. Oh what wonders God hath made! Or whoever you chose to believe, it can't be by accident, it must be design.

Didn't you know a new star is born on my b-day every year? This new star they are talking about is mine. :-D :-D :-D

lol You didn't get it. I meant that star was discovered on my b-day.

Rygel and Booboo - Rygel, the white eared cat and Booboo
really, well, i have 26 little kitty stars running around my house!

It seems to me that this system formed by the capture of the pulsar by the sun - like star. The pulsars elliptical orbit would seem to support this I think.

I'm no expert, but in a two star binary system which this effectively is, the two objects orbit round a common centre of gravity. I don't think that the mass of of the two objects is really relevant, it would just be necessary for the pulsar to approach close enough to swing each of them into a stable orbit around each other.

But the theory has always been that pulsars are heavy objects so how could a sun-type star capture a super heavy object?

I love anything that has to do with our world and our solar system also. It all amazes me to no end. I love to rent movies and documentaries about these types of things also. There is alot of information in them that I truly find is very entertaining. I love to know what is going on in the world and how things have and will happen in the future also. There are alot of things left to question that the scientist are still trying to figure out. I have alot of interest in it also but I am not even close to a scientist to try to figure it all out.

Don't ask me to do the math, just let me stare in awe at these wonders! I figure if I find it interesting, others will too.

LOL. Okay. I won't ask ya. I love everything about the stars and the moon and the planets. I love to look through my husband's binoculars at the stars and the moon at night time. I had a telescope at one time but could never get it to work right.

Thanks Elic for sharing this. One of my very first loves when I was a kid was astronomy, in fact, at one time I was thinking of becoming an astronomer myself. The technical mathematics got in the way though as that was my worse subject...but I do understand about speed of light, light years, parsecs..and so forth. It's amazing that in our so-called advanced scientific age however, we are STILL learning about the universe around us. That pulsar, 21,000 ly isn't really all that far away either..the closet galaxy for instance is Andromeda and that is 2 million light years away--Have to check up the statistics here, but 21,000 light years away??? Then that pulsar is within our own galaxy, no???

It sounds like it to me. I think we are just getting into advance science myself, I would so love to see what people could accomplish in a hundred years considering what we've done in the last hundred.

Thanx, Elic. SOME might just shake their heads & say, "And this pays the bills HOW?" But not I. You know me, I eat this stuff up! Maggiepie

I know, Maggie, and I find these things just a recognition of the fact that God can do anything he wishes.
