here is the info on...The discovery of a rare magnetic star - or magnetar - is challenging theories about the origin of black holes.

"Magnetar" sounds like it should be a Transformer name.

the thread title got me to think of Matt....strange.

Just to keep things straight, magnetars are not new (not even close), the discovery of Westerlund 1 as a magnetar is.

aaa ok haha sorry
i just gathered from what i read ("The discovery of a rare magnetic star...") that it was new :S

It's hard to imagine an object with a diameter the size of Saturn's orbit;
2 866 898 740 km.

Bummer, that is a couple years old. Last year they found a couple even larger. But the first primordial stars made even VV Cephi look like a baby, or so we believe.


And hey to some of us Pluto always was and will be a dog, err planet. Well definitely a dog.

No! and get over it. :devil:

Anybody truly interested and has access to it, heres a link to the actual paper. It was a good read!

I wonder what will happen when this monster goes supernova : http://www.popsci.com/technology/article/2010-07/eso-researchers-find-biggest-star-ever-seen-265-times-larger-sun

will probable cause a Hypernova and add a nother damn black whole to our universe, there are loads of the now-a days hehe (i think :) )

what isevery ones favaorite subject when it comes to Space.
mine it black whole holes
i just cant get my head around how powerfull they are i mean it stops there, nothing beets a black hole, thats were it ends nothing mor powerfull, (as far as i know anyway) i jsut cant get my head around it haha

My final paper in astrophysics was the Shoemaker-Levy comet impact with Jupiter.

haha i have just looked that up (im normaly good with knowing things to do with astronomy but i had to look that up haha)
and that begain 2 days after i was born haha so was 2 days old when that happend haha
(Shoemaker-Levy 9 collided with Jupiter on July 16-22, 1994, for any one who dosent know)

My fav and something I do a lot with is WR Collapsar models (forming black holes with GRB's) as well as MHD methods for forming jets from the accretion disk around black holes.

The other thing I really get into is galactic collision dynamics.

[EDIT]Sorry, before people ask, WR = Wolf Rayet stars, GRB = gamma ray burst, MHD = magnetohydrodynamics

aa cool cool
are thay hard to do?
iv only attempted a black hole onece and it was a complete desaster hahaha :)

It was fascinating. For months we knew about the comet and its trajectory, but nobody knew what was going to happen, only speculation. Many supercomputer cycles devoted to simulate the collision, at the end was very anticlimatic, aside from the brilliant explosions.

First, as someone that dabbles, OK a little less then dabbles, maybe just reads about, astro-atmospheric-chemistry, Shoemaker-Levi9 was HUGE and far from anti-climatic. Scientists are still studying and modeling from that data especially with the birth of the mini-redpsot and what happens when the two red spots pass each other like they did just last week.

But on the more exciting and S-L9 related front, check out this video footage shot Friday of a fireball on Jupiter!!!http://libra-co.com/Jupiter2010Aug20182212UT.wmv
