Not as far as anyone knows, and it's really very unlikely.
Traveling at the speed of light ... which is impossible for people ... it would take millions of
years ... which is longer than people have existed ... to reach the Andromeda Galaxy. So
it's probably a safe bet that earth people have never been there.
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
There have not been counted yet.
The collision of Andromeda with the Milky Way is not expected for many billions of years, by which time the Earth will have already been destroyed by the expansion of the sun into a red giant.
It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.
Since the Andromeda Galaxy is about 2.4 million light years away, when we observe it, we are seeing it as it was 2.4 million years ago. This is because the light we see from the galaxy today has taken approximately 2.4 million years to travel from the galaxy to Earth.
Astronomer's have not been able to count all the planets in the Andromeda Galaxy. The Andromeda Galaxy is home to one-trillion stars. The Andromeda Galaxy is expected to collide with the Milky Way in the next 4.5-billion years.
No. The furthest "man" has gone is the moon.
Nothing as far as I know. It is still the same as it has been for years
The Milky Way galaxy is the brightest and most visible to to the naked eye Andromeda, which can been seen with the naked eye, and is 2.2 million light years from earth.
Because the Andromeda galaxy is so distant it is significantly difficult to identify planets in it - although there are likely hundreds of billions. Using a technique called gravitational microlensing, one planetary candidate within Andromeda has been announced by a team of scientists; the exoplanet is a stellar companion and thought to have about six or seven times the mass of Jupiter.
Never - its not alive. But it has existed for many billions of years, almost 13.
The joke in which a blond says she does not know which is bigger, the Earth or the galaxy, because she has not been to the galaxy is a mockery of blond people. The Earth is in the galaxy, so she has been to the galaxy. The joke implies that she isn't smart enough to realize that she is in the galaxy.
