Our scientists have studied THIS galaxy, a little at least, using telescopes. We have never left the very near neighborhood of our own planet, and probably won't within the next several decades. It will be hundreds of thousands of years, if ever, before human scientists visit even the nearest neighboring galaxies.
==============================================
Another contributor agreed:
No human being has ever been more than roughly a quarter-million miles away from
Earth. That's about 0.003 of the distance to the sun, and about 0.000000009 of
the distance to the next nearest star, out of maybe 400,000,000,000 stars in our
own galaxy. We have a long way to go before anybody will ever visit another galaxy.
Scientists are trying to figure out
It's not possible that we could cross a galaxy. But astronomers study galaxies with huge telescopes.
Satilights take pictures of the galaxy, and scientists make hypothesizes.
Scientists determine the amount of mass in our galaxy by studying the movements of stars and other celestial objects. By observing how these objects move and interact with each other, scientists can calculate the total mass of the galaxy. This helps us understand the structure and dynamics of our galaxy.
The galaxy in which our solar system is located has long been known as "the Milky Way". Scientists refer to it as "our galaxy", or more often just " the Galaxy".
The redshift tells scientists how fast a star or galaxy is moving away from us.
Scientists estimate that there are around 58 billion star systems in our Galaxy.
Cosmologists.
They do not say that.
yes they as scientists found in the middle of the messier galaxy
Scientists determine the rotational direction of the Milky Way galaxy by studying the movement of stars and gas in the galaxy's spiral arms. This movement helps them understand how the galaxy spins on its axis.
Because it's where we live.
