How do we see Galaxies ??

Question

In science magagines u can read about billions of billion galaxies all around the universe,,
well we know radio wave telescopes r used to get the idea of their shape, size n distance.
Do u know more about it, some new invention to see these far away galaxies !! do tell ??

Answer 1

Apparently, the newest thing is... GALAXY HUNTERS!

I know, sounds rediculous. But take a look...

Imagine a universe with no stars, no galaxies, and no light: just a black brew of
primordial gases immersed in a sea of invisible matter. Beginning a few hundred thousand years after the blinding flash of the big bang, the universe plunged into a darkness that lasted almost a half billion years. Then something happened that changed it all, something that led to the creation not just of stars and galaxies, but also of planets, people, begonias, and lizards. What could that something have been?

New clues to this puzzle—one of the most fundamental in cosmology—are pouring in from many directions. Theorists using supercomputer simulations have retraced the steps that produced the first stars and galaxies. Astronomers peering through giant new telescopes have journeyed back in time in search of the first galaxies. Researchers studying images from the Hubble Space Telescope have discovered the breathtaking diversity of the galaxies that surround us today—from giant pinwheels blazing with the blue light of newborn stars, to misshapen footballs glowing with the ruddy hue of stars born billions of years ago, to tattered galaxies trailing long streamers of stars torn out by collisions with intruder galaxies.

Less than a century ago astronomers knew only about our own galaxy, the Milky Way, which they believed held about 100 million stars. Then observers discovered that some of the fuzzy blobs in the sky weren't in our own galaxy, but were galaxies in their own right—collections of stars, gas, and dust bound together by gravity. Today we know that the Milky Way contains more than 100 billion stars and that there are some 100 billion galaxies in the universe, each harboring an enormous number of stars.

Our view of the universe is changing completely, says cosmologist Carlos Frenk of the University of Durham in England, and it's largely because of our new understanding of galaxy formation: "It's no exaggeration to say that we're going through a period of change analogous to the Copernican revolution."

Answer 2

You can see a few yourself with a pair of binoculars, if you know where to look. Galaxies tend to be dim, though, dimmer than stars, so generally you need a good telescope to see them. With a really good telescope -- the giant kind that astronomers use -- you can see billions. Here's a photo from the Hubble Space Telescope showing a few hundred, in an area of the sky that looks black to human eyes:

Answer 3

well hubble telescope can see millions with its lens, basically just looking into the sky and counting. If we had a bigger telescope like the size of earth we would see even more stuff. Hell we might see right into another universe. I mean we might be able to read the EXIT ONLY sign at the end of our universe like in the movie The Truman Show. Plus matter in space makes noise and colors its just basically mass observation. if we didnt have the scientific tools that we already have hell we might not even have realized how everything works. i mean, the universe might only be a small part in the puzzle. There might be something even bigger out there. I find it exciting and I would love to be the first one to find out. I love the movie Contact.

Answer 4

join an astronomy club or ask a science teacher or somebody who owns a VERY good telescope. Galaxies can be seen as white swirly blobs in the sky if you know where to look for, but only with very good telescope you'll see their shape and difference in the light and swirls.

Look for your local astronomy society, I bet they can teach you where to look and howto use telescope.

Answer 5

The Hubble telescope has been used to view most of them.

Answer 6

a galaxy is just a cluster of millions of stars, i guess we see them using telescopes, like the hubble telescopes. we cant see galaxies with the naked eye, i think.

Answer 7

poem,the hubble telescope uses onboard and earthboard computers to make hugely amplified and brilliant color photographs of ,for 1 example the orion constellation,which looks like a monster head coming toward us,computers combine radio frequencies and visible and invisible light to make these photographs.

Answer 8

Um...
eyes are good but telescopes are better...
umm maybe u shall go to NASA and see if u can get answer there they have superb telescopes u know...
well...
at least i tryed

Answer 9

with our eyes or telescopes

Answer 10

eyes?
