Here are some of the ways: (1)
We use computers to help run big telescopes
, the instruments that collect data, and the satellites that study stars and planets. (2) We use computers to analyze the data and try to understand what the data mean.
How did we learn about space?
Scientists learned quite
a bit with telescopes
. This paved the way for more space exploration. Humans have taken trips to the Moon and dozens of space shuttle flights. They have traveled in space and carried out research on many scientific subjects.
What do we use to study the universe?
Here are some of the ways: (1) We use
computers
to help run big telescopes, the instruments that collect data, and the satellites that study stars and planets. (2) We use computers to analyze the data and try to understand what the data mean.
When did we learn about the universe?
January 1, 1925
: The Day We Discovered the Universe | Discover Magazine.
How do we know about the universe?
The expansion of the universe was
discovered in 1929 by American astronomer Edwin Hubble
. He used the 100-inch telescope on Mount Wilson in California – at the time, the largest telescope in the world – to measure the distances to other galaxies. … Today, we call such a graph a Hubble Diagram.
What is the galaxy we live in?
We live in one of the arms of a large spiral galaxy called
the Milky Way
. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. 100 000 years to cross from one side to the other.
Why do we need to study universe?
By studying the cosmos beyond our own planet,
we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth
. In astronomy, the Universe is our laboratory!
Who made the universe?
The earliest cosmological models of the universe were developed by
ancient Greek and Indian philosophers
and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System.
What can we learn from the space race?
The list of technology from the space race goes on. Consumer products like
wireless headsets, LED lighting, portable cordless vacuums
, freeze-dried foods, memory foam, scratch-resistant eyeglass lenses and many other familiar products have all benefited from space technology research and development.
How many universes are there?
There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is
one, only one universe
.
What is outside the universe?
To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then
there can’t be anything outside the universe
.
How did the universe begin?
The Big Bang
was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. … The matter that spread out from the Big Bang developed into everything in the universe, including you.
How old is our galaxy?
Astronomers believe that our own Milky Way galaxy is
approximately 13.6 billion years old
. The newest galaxy we know of formed only about 500 million years ago.
What universe do we live in?
Our home galaxy,
the Milky Way
, contains at least 100 billion stars, and the observable universe
Which arm of the Milky Way do we live in?
In recent decades, research advances have revealed that we live in our very own spiral arm of the galaxy, albeit a relatively minor one. Our spiral arm is formally called
the Orion-Cygnus Arm
. It’s also known simply as the Orion Arm or Local Arm, and you sometimes still hear the names Orion Bridge or Orion Spur.
