Why don't we see Quasars locally(nearby)?

The answer is (A) most quasars happened a long time ago, so we can only see those that are very distant.\n\nQuasars are the precursors of galaxy formations. They are gigantic blackholes ejecting enormous amount of energy at their poles. These massive blackholes are now at the centers of all galaxies, including our own the Milky Way. So the quasars haven't disappeared, they've just turned into the galaxies that we see now.

such a waste of space if we were alone.\n\n if you could just imagine yourself looking on our milky way from another outside.. \n\nhow infitestimally small we truly are... we are nothing but dust on a small rock revolving a small star..

Objects can't change their brightness faster than the time it takes a light signal to travel across their width.  Quasars change their brightness very fast, so we can infer they are very small for their energy output.

It's because even at 'only' 4.3 light-years away, you have to remember that Alpha Centauri is only about the size of our sun, or 1,400,000 kilometers.  A light year, however, is almost 10 *trillion* kilometers.  So Hubble is trying to look 40 trillion kilometers to see something that's only 1,400,000 kilometers across.  The angular resolution of the Hubble Telescope simply isn't good enough to see an actual disk for Alpha Centauri.  Hubble's power lies not in its resolving power (It can't even see Pluto all that well...see my last source below), but in the fact that it lies above the Earth's atmosphere.  In fact, almost all of the famous telescopes today, such as the Keck telescopes, have mirrors that are bigger then Hubble's, and they can't see Alpha Centauri either.  With an object so small, and so far away from us, all the stars in the sky simply appear to be point sources.  It's a testament to the power of stars that we can see them at all from so far away.

The nearest black hole known to us is near a visible star called V 4641, in the constellation Sagittarius just 1,600 light years away in the direction of the galactic center.  It is about 3 to 10 solar masses and is classified as a microquasar.

Our local group is inside our galaxy. It is a group of nearby stars. Yes there are billions of other galaxies outside of our Milky Way, but there are none within our local group.

Who knows? Don't you think that speculating about the beginning of the universe is far reaching enough, you want scientists to posit ideas which predate that for which there would be zero testable merit to? Maybe there are other 'universes' outside ours some quadrillion light years away popping off big bangs all the time. Maybe before the big bang there was a big collapse where all this matter and energy fell together into a ginourmous abyss-hole. Who knows how many orders of existence could be identified beside what is within our range to observe.\n\nI mean trying to see the forest through the trees is one thing, but trying to see the sattellite image through a microscope is just ridiculous.

I think maybe the separation is smaller than the resolving power of my eyes rather than the angular separation of my eyes. So I can't resolve the two sources and just see one bright star. \n\nBest of luck - Mike

A resounding YES! The reason we haven't met them is quite obvious, really. The incidents of life as we know it are so far apart that it would take more time for them to reach us or for us to reach them than any given life form in the universe has. In other words, we will all die and all trace of our existance will be long gone by the time any other beings got here. Take it from an alien!

Yes, it is possible to see a galaxy in a telescope.\n\nDepending on the strength of the telescope, the galaxy will appear very VERY faint and look like a star itself.\nYou probably will not be able to see any with an ordinary telescope in your back yard, or if you do, it will just look like a faint star.

I think that simple answer is, no one knows. We have theories, but we really do not know. \n\nFor example, maybe the antimatter particles decay much faster (see reference). Maybe the universe is only locally mainly matter, and there are other patches of the universe that are locally mainly antimatter (see reference). \n\nWhat science is, is a series of problems and questions that scientists attempt to answer. You have asked one of those questions that is so far, in the unresolved category.

Yes, there are a few of them, I beleive they are called Quasars, and they fluctuate through the color spectrum. I see one a lot at my camping spot in the summer. I dont have my star chart right now, or i could tell you more about it.

It all depends on how bright the thing we're looking at is. \n\nIn one sense, the farthest thing we can 'see' is the cosmic background radiation, which is essentially the glowing leftovers from the big bang.  That light has been traveling for 13.7 billion years away. It's probably impossible to see anything further than that, because the universe was opaque before then.\n\nThe farthest discrete object is a quasar whose light has been traveling for 13 billion years.\n\nOne thing to be careful of is that when you're talking about these extremely distant objects, space and time get sort of mixed up.  For example, that quasar was about 4 billion light years away when it emitted the light we're seeing now, the light has traveled for 13 billion years, and the quasar is about 27 billion light years away now.

No where can it be seen?

In the 1980s, unified models were developed in which quasars were viewed as simply a class of active galaxies, and a general consensus has emerged that in many cases it is simply the viewing angle that distinguishes them from other classes, such as blazars and radio galaxies. The huge luminosity of quasars is believed to be a result of friction caused by gas and dust falling into the accretion discs of supermassive black holes, which can convert about half of the mass of an object into energy as compared to a few percent for nuclear fusion processes.

It doesn't work that way. Because the universe is still expanding, if you were to stand still at one edge of the universe, you would see the opposite edge traveling away from you at FASTER than the speed of light. (That's one of the peculiar thing about quasars ... they're so far away that the expansion of space between that location and this location makes them appear to be traveling faster than lightspeed.)\n\nSo how far from one side of the universe to the other? Too late! It's already changed! How about now? Too late again! It's already ... and so on.

You can see them. but not right now. if you want to see the same sky as asturiala sees right now wait till fall.
