Using some basic maths, based on in which constellations they are apart, can anyone please caluclate how far they are from each other after knowing the degrees of the constellations or their locations there ?

i.e. :

The most farthest object A is say at longitute 10 right now and the second most farthest object B is at longitude 180; so these object make a Obtuse angle triangle from earth. What is the length of AB the side opposite to the angle formed at E, earth ?

can you rephrase the question?
it doesn't make any sense the way it's written

I will edit the first post

What's the matter, Anom, you don't know any basic math either? (In addition to all the other things you don't know.)

Obviously not, because no one could compute the length of the line with just the information you've provided.

As a computer might say, "Insufficent data."

The concept of distance is very difficult in an expanding universe. What is it you want to know-
the location of the most distant objects which have yet been detected? Bear in mind the objects concerned have moved since they emitted the light which we now observe. Because of the expansion of the universe, they are probably many tens of billions of light years away by now.

Do you want to know how far apart they are now, or how far apart they were when they emitted the light which we now see? If you want to know how far apart they were when they emitted the light now reaching us, that too will be a strange and surprising statistic.
The most distant objects we have seen in the universe so far are very young active galaxies, which emitted the light we now see 13.5 nbillion years ago; in those days, the universe was a lot smaller, so these objects were a lot closer together than they now appear. In fact these galaxies might have only been two or three billion light years apart; perhaps less.


Confused? You will be.

Oh, I got it - and I remember when you first said it. Not only that but you keep reminding us by the things you say in about every other post.

To get the answer you want, you'll need to at least know the distance to one of the objects in addition to the angles you provided.

And I don't know where they are either but I know that they are quasars. I really don't gave much interest in extreme-deep space astronomy.

....Bear in mind the objects concerned have moved since they emitted the light which we now observe. Because of the expansion of the universe, they are probably many tens of billions of light years away by now. So

1) does that make our universe 28billion light years old ?

2) for the distance that light took 14 billion years to cover, how much do U think we must have moved from there to here ?

3) based on the redShift if we could determine our average speed of going away from the most distant objects then I am sure age of the universe will cross 100s of billion years if not trillions from that point of distance.


Do you want to know how far apart they are now, .... Lets start with the now part for the time being. But that depends on the location of the most distant object apart from eachother in the sky from earths point of view.

The most distant objects we have seen in the universe so far are very young active galaxies, which emitted the light we now see 13.5 nbillion years ago; in those days, the universe was a lot smaller, so these objects were a lot closer together than they now appear. In fact these galaxies might have only been two or three billion light years apart; perhaps less. so where are they in our sky ?

The most distant object known is the protogalaxy Abell 1835 IR1916, discovered a couple of years ago by R. Pello. It has a redshift of z=10
http://xxx.unizar.es/abs/astro-ph/0403025

The second object in the distance ladder is a galaxy with z=7, discovered by Kneib
http://hubblesite.org/newscenter/newsdesk/archive/releases/2004/08/text/

I will let to you to discover the distance between these 2 objects

Edit: in fact, if you're interested in distant objects, look table 1 of the following paper. It gives the redshifts of the 10 most distant galaxies and protogalaxies known
http://www.kas.org/e-journals/Web_JKAS/data/382/v38n2p73.pdf

Ok so the most farthest object Abell 1835 is in the Virgo constellation and
the second most farthest object Abell 2218 is in the Draco constellation,
Both roughly at 13 billions light years away.

Any idea how to get the degrees distance between them ?

the problem is that they may not be in a straight lattitudes or longitudes planes according to human sky maps.

Any good sky Maps site that can search constellations and show the positions in degrees ?

good question.

Try 'starry night' software.

Try 'starry night' software. Thanks, but I thought some experts here could have helped me, but it seems no one is interested, so I too will go back to my cave.

Few are interested in dealing with your resistance to understanding and learning.

Welcome to ignore :rolleyes:

Sounds like you're asking about spherical trigonometry. That is - distances between objects on the imaginary "celestial sphere".

For that, check out
http://www.hps.cam.ac.uk/starry/sphertrig.html

Note that these distances do not correspond to physical distances, they just give the angle between objects in the sky.

You mean assuming the universe is expanding right? Because afterall that is only a theory; not a solid-proven fact.

quasars...are usually the most distant objects found in universe...Abell 2218 magnifies this unnamed quasar 25x...for example

But you said two...so...the second one is called Sharon...no not the Israel...but Sharon in the universe...also called STIS 123627+621755 .... here it is...

They are the most distant objects that we can see with our current technology. There could be many types of undiscovered energy lying outside the bounds of the sight of our most powerful telescopes.

Just because you can't see what's beyond the horizon does not mean nothing exists on the other side.

No, it is not a theory but a well proven and accepted fact.

These two objects are located at a distance of over 13 billion light years from us, if you take the Light Travel Time Distance. This means that they will be no more than 27 billion light years from each other, measured using the same yardstick.
But if you take the location of the objects where they are now you will need the Co-moving distance; they might be as far as fifty billion light years away by now, or more, and so could easily be a hundred billion light years apart. Worse than that, they are outide each other's observable universe, so you could never travel from one to the other, even if you went at the speed of light for ever.
So on that scale they are effectively infinitely distant from each other.

They are the most distant objects that we can see with our current technology. There could be many types of undiscovered energy lying outside the bounds of the sight of our most powerful telescopes.

What exactly does lie beyond these protogalxies, and can we 'see' it and/or detect it? I've been pouring over some of the Hubble Deep Field pictures, and I have been very intruiged by what could lay beyond even the galaxies in the picture.

Also, I know that there may or may not be an edge to the universe, but is there an edge to the visible universe? That is, a point where there are no more galaxies, only empty space? I have been confused with that for a while.

arrgh

We have just about reached the limit of what can be seen. The early universe, after protons and electrons had formed, but still too hot for atoms to form, was a plasma. Plasma is opaque to all EM because of the free electrons.

No, it is not a theory but a well proven and accepted fact.


Yes, that the universe is expanding is an observed fact. Note the Hubble constant and recent work with supernovae in distant galaxies. The Big Bang is a theory that explains this phenomenon.
