Is the Milky Way the only known galaxy?
Most of the stars in our galaxy are thought to host their own families of planets. The Milky Way galaxy is just one of billion of galaxies in the universe.
How many different galaxies have been discovered?
While NASA previously determined that there were around two trillion galaxies in the universe, new findings say the number is more likely hundreds of billions. While NASA previously determined that there were around two trillion galaxies in the universe, new findings say the number is more likely hundreds of billions.
Will we ever visit other galaxies?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Who found Milky Way galaxy?
Galileo was the first to see the Milky Way Galaxy in 1610 as individual stars through the telescope.
How Milky Way was discovered?
Ancient Greek philosophers proposed that that Milky Way might be a vast collection of stars, to dim to make out individually. But the first actual proof came when Galileo Galilei pointed his first rudimentary telescope at the Milky Way in 1610, and was able to see that the Milky Way was made up of countless stars.
When was Milky Way discovered?
How do scientists know about other galaxies?
Although we cannot visit the other galaxies we can see that they are there through telescopes—that’s how we know they exist. An astronomer called Shapley took the position that they were in our galaxy, while another astronomer called Curtis argued that they were outside it.
Who discovered that the Milky Way is just one galaxy?
Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated visible diameter of 100,000–200,000 light-years.
What is the difference between the Milky Way galaxy and universe?
Most of the stars in our galaxy are thought to host their own families of planets. The Milky Way galaxy is just one of billion of galaxies in the universe, The universe is a vast expanse of space which contains all of everything in existence. The universe contains all of the galaxies, stars, and planets.
What is the Milky Way’s nearest neighbor galaxy?
The Milky Way galaxy is in the Local Group, a neighborhood of about 30 galaxies. Our nearest major neighboring galaxy is called Andromeda. 5 More Planets Than Stars
How many planetary systems are there in the Milky Way galaxy?
This means there are potentially thousands of planetary systems like our solar system within the galaxy! Our Sun is one of at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across.
