SN 2011fe Type 1a Supernova in M101..!!!

[caroby]

Discovered on Tuesday the 23rd of August.

Boys and Girls, this one is HOT...! Gonna be talked about in a similar fashion liken to SN 1987.

This, the closest Supernove of it's type to us in a long while... Yes, it's in another galaxy. It's just that its been since 1972 since the last >>confirmed<< type 1a has been seen within 35 million light years of Earth (Relatively close)...! Prior to this the closeset Type 1a was Tycos super nova back in 1572 @ 8,000 light years distant in our own Galaxy http://en.wikipedia.org/wiki/SN_1572..

This one is gonna be studied heavily over the coming weeks..

Pretty cool!

Find the Big Dipper...

M101 is Slightly NNW "between" the stars in the handle of the Big Dipper (The last two stars of the handle Mizar and Alkaid ... BTW Mizar is a Binary system)...


Were the heck is M101.......


M101 is considered one of the GRAND Design Spiral Galaxies... Thought of to be 1.5-2x the Diam of our galaxy and 2.5x the mass.... Just beautiful..!

Get them telescopes out...

I'm confused. If it is 21 million light years away, how the heck did they catch the explosion within hours of it happening? It had to have happened 21 million years ago for the light to get here - and no phenomena associated with it can get here sooner than that. So they caught it 21million years (plus or minus a million or so?) and a few hours after it happened?

The super computing and detection routines noticed the event relatively quickly after the light showing it arrived following it's ~21 million year journey here from where it happened. It will be another 21 million years before we know what is happening there today. What this amounts to is very early detection of really old news.

""It will be another 21 million years before we know what is happening there today. What this amounts to is very early detection of really old news. ""

FUNNY...! True too...

Time and space............... Hard for this Benchrester to wrap his mind around it........ Shooting little aggs at 100yds TOO..!!!
HAAAAAAAAAAAAAHHHHHHHHHHHHHAAAA!!!Sad....!hehe

Here's one..... This new Supernova discovery is well, news to us.... Photons been traveling for 21 million years ("old news" to Space Time)......
Ok.... The beautiful 1572 Tycho's 1a Supernova has been know to man since 1572.... The light took about 8,000 years to get to Mr. Brahe's telescope back in 1572.... Long time but nothing compared to 21 million...!!! Funny how "we've" known about Tycho's supernova for the last 400 some odd years....("old news" to us but Relatively new to Space Time). And we are just now seeing this "new" SN..

As I said before..... It's a GOOD thing the White Dwarf around Sirius (Brightest night-time star in our sky and at around 8 light years away http://en.wikipedia.org/wiki/Sirius) orbits far enough away from Sirius A or we would have no future.... Kill zone away from Type 1a Supernovas is thought to be less than 250 light years.... Some say further, some say closer.... But at 8 light years.... We Would Be Toast...LITERALLY.

Fitch, they didn't catch it as it happened, they caught it when it became visible to us....21 million LY after it happened. However from our perspective it is happening now. Interesting huh?

Yup, I got that part (really early detection of really old news). I spent 35 years in aerospace, lots of time to ponder now and then on the truly mind bending realities of the universe. I'm as mind boggled now as I was then, the difference is now I'm not surprised I don't understand it, and I'm pretty sure nobody else does either. The speed of light limitation (assuming we could ever even approach that which is a huge assumption) on emigration to another solar system combined with the finite life of our sun may mean nobody ever will.

We all know what a moa is. Take a picture of the sky that large, expand it, and you will find that small portion, any portion is filled with 10's of thousands of galaxies.
