Ancient Galactic Black Holes
You're no doubt aware of how powerful the Spitzer Space Scope is. NASA can take alot of credit here. Astronomers have discovered what seem to be the earliest, most supermassive black holes known to mankind. Whew....
What they've basically found - and what it means to understanding our own origins - are ancient quasars born in a dust-free universe - the earliest stages of evolution. (A quasar is what you get when matter interacts with massive black holes. It gives off radiation and more light than any star) The universe didn't have any dust at its inception which tells astronomers that quasars from that time should also be dust-free. But no one has seen one - UNTIL NOW! Spitzer has identified two, the smallest on record, about 13 billion light years from earth. O yea. Here's a quasar over 3 billion light years from earth; isn't it beautiful?
Below is an image caught of a supermassive massive black hole as it eclipses in its galaxy NGC1365 (NGC=New Galactic Cataloge)So think about it: these supermassive black holes existed around the time the early universe did not yet have the ability to form dust, about a billion years post Big Bang. The picture below is of a system containing two quasars about 4.6 billion years away. Now that's pretty amazing since the scientific age of earth is 4.6 billion years old. You're looking at something just as it appeared when earth was still forming out of colliding asteroids, comets, etc.
We're gazing back at the beginnings of time and space - nothing less.

Now for your jaw-dropping viewing pleasure, this is the image taken by Hubble of "The Veiled Black Hole". The left is the x-ray image and the right shows the galaxy it is interacting with. That's right - black holes are not black.

I found this subject facinating ~ I loved the pictures ~ Ally x
amazing....
much love
This is mind boggling and asks one to ponder a lot on the origin of life. To think that black holes aren't really black? Is the light coming from planets being swallowed up or explosing as they enter it Are they the entrance to a parallel dimension or universe? Thanks for giving my old brain a whack. lol I will lie awake wondering about it all now. lol
Great pictures Cathy!
Great entry too.

I wonder if you ever gave like a seminar or something of that nature at a library or observatory. I think you would do a wonderful job.
Each time you post an entry, I find that I am entranced as I look into the infinte. 'Dare To Think' is certainly a proper fit for this blog!!
I'm with Mark. Give lectures or something.
I read that it is thought the holes are they way they are because they are drawing pariticles into themselves fsster than the speed of light.

Beautiful images! Thanks!

This is absolutely brilliant..mindblowing..shtuff!
LOVE IT!
Wow that is so interesting Cathy...there is so much we don't know or are just discovering. The pictures are amazing; but why do we call them black holes? They are so colorful and beautiful...thanks for posting on this fascinating topic.

Pictures like this is one reason why I'm hooked on the science channel:) Amazing info to bounce around in one's head.LOL
wow man
Beyond Our Dreams.Lovely Post Cathy .
Hi Kathy,
Thank you for the truthful, candid comment on my humble Blog: TOM'S JOURNAL. Few people now days have that precious commodity.
And to a large degree, I agree that much if not most "organized religion" is dangerous to your everlasting life.
I choose to put all my 'Faith' and trust in Jesus Christ, and the KJV Bible. Please see: biblefortoday.org
Warm Regards,
