Diameter of the universe?
With current technology, astronomers are able to detect objects (galaxies) out to about 14 billion light years from us in every direction. We don't know what's farther than that.
How long do astronomers attend college?
they attend for Jack Dombrowski number of years.
How do astronomers locate other stars trillion light years away?
They can't. The universe is only about 13 billion years old. If there are galaxies a trillion light years away their light has not reached us yet and due to the expansion of the universe, never will. At the edge of what we call the observable universe we cannot make out individual stars, but we can detect galaxies using infrared telescopes.
Atronomers believe that the solar system is about how many years?
Our solar system is thought by astronomers to be about four and a half billion years old.
Which is the biggest known black hole in the universe?
The supermassive black hole that hosts the galaxy NGC 1277, in the constellation Perseus, is currently the largest black hole in our visible universe with a mass equivalent to 17 billion suns. In 2012, astronomers have discovered this small galaxy about 250 million light-years from Earth.
How long have astronomers been trying to find out what the sun orbits?
For two or three hundred years, astronomers have had a fair idea the the Sun is not the center of the Universe.
How do astronomers know the universe is infinite?
The universe is not infinite. It is 156 billion light-years wide. A light-year is equivalent to about 9,500 billion km
How do astronomers find out about changes in galaxies over time?
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
The universe is so large that astronomers measure distance between stars instead of kilometers?
light-years, parsecs, and megaparsecs
How astronomers can predict planetary alignment?
How can astronomers predict planetary alignment
Whats the biggest struture in the universe?
Astronomers have found a mind-bogglingly large structure so big it takes light 10 billion years to traverse in a distant part of the universe.
What do you think that astronomers mean when they use the term observable universe?
They mean the part of the universe that we can see with the naked eye, through telescope, or the amount of light years we can travel without dying
How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
When do astronomers blieve the solar system was formed?
By studying rocks from Earth, from the Moon and meteorites it is believed that the age of the Solar System is approximately 4.6 billion years old.
Does the universe have a definite size?
The universe has been continuously growing since the Big Bang, and there is no way to accurately measure it, so no. Comments: In fact astronomers have estimated the size of the "Observable Universe". They say there's probably a lot more that we can't see. The Universe is about 13.8 billion years old. That gives the maximum distance we can observe as 13.8 billion light years. But while the light from the "edge" of the Observable Universe has been travelling to us, the Universe has been expanding. Astronomers have estimated how far away that edge is NOW. The usual estimate given for the "real" radius of the Observable Universe is about 46 billion light years.
Who is the famous ancient astronomer?
There were many famous ancient astronomers, and astronomers from hundreds of years ago (not exactly ancient. but vital to our present understanding of astronomy). They include:HipparchusPtolemyCopernicusGalileoEudoxusThere were also many Egyptian, Mayan, and Chaldean astronomers whose names have been lost over time.
