Andromeda Galaxy

According to a recent research, the spiral disk of stars in Andromeda is three times larger in diameter than previously estimated. This constitutes evidence that there is a vast, extended stellar disk that makes the galaxy more than 220,000 light-years (67,000 pc) in diameter. Previously, estimates of Andromeda's size ranged from 70,000 to 120,000 light-years (21,000 to 37,000 PC) across.

The Andromeda galaxy rotates at a speed of about 100 to 200 kilometers per second at its outer edges, and faster towards its center. It takes approximately 200 million years for Andromeda to complete one full rotation.

The distance to the Andromeda Galaxy is estimated at 2.5 million light-years. The distinction between "near side" and "far side" is irrelevant, since the diameter of the Andromeda Galaxy is probably less than the error in the distance estimation.

No scale was specified.

However, if the Earth was one inch, the Andromeda Galaxy would be 29,300,000,000 miles away.

We can tell the distance is decreasing because the light from Andromeda is blue shifted. That galaxy is closing in on us (or vice versa) 500,000 km (300,000 miles) per hour.

It would take approximately 2.5 million years for a radio signal to travel from Earth to the Andromeda galaxy, which is about 2.5 million light-years away.

It has the same things the other galaxies have i.e. stars planets etc . It's just that it is very big .

Comments : I think the answer may be that Andromeda gives out light that

is blue shifted instead of the red shift for most galaxies.

So the answer is " a light spectrum that's blue shifted".

Both the Andromeda galaxy and the Milky Way are spiral galaxies that are part of the Local Group of galaxies. They have similar structures with central bulges surrounded by spiral arms. Additionally, both galaxies contain billions of stars and are part of the larger cosmic web of galaxies in the universe.

The Andromeda Galaxy has an apparent magnitude of +3.44

Andromeda is a constellation, but because one of the best-known and most-photographed galaxies is M31, the "great nebula in Andromeda", the name is often used to refer to the galaxy.

Charles Messier was a French astronomer who was a fanatic about comets. Most of his astronomical observations were done while hunting for comets. But there are a lot of faintly bright fuzzy things in the sky that are NOT comets, and Messier achieved lasting fame for his list of things that look like comets but are not comets.

M31 is "item number 31" in Messier's list of fuzzy things that aren't comets.

At the base which is kinda like a nucleus, is a bright yellowish color. surrounding it is what looks like dust clouds (or so what i've been told), at the beginning is brown and continues into a deep purple and blue and black. then surrounding it are the stars

To see the Andromeda galaxy, you will need a telescope with an aperture of at least 6 inches (150mm). This is because Andromeda is a large galaxy and its light is spread out over a wide area in the night sky. A larger aperture will allow more light to enter the telescope, making it easier to observe.

Traveling at the speed of light, it would take about 2.5 million years to reach the Andromeda galaxy, which is approximately 2.537 million light-years away from Earth. However, current technology is far from achieving such speeds, making intergalactic travel to Andromeda currently impossible for humans.

A trip to the Andromeda galaxy would take about 2.5 million years traveling at the speed of light, which is currently beyond our technological capabilities. It would require significant advancements in space travel, propulsion systems, and sustainability for human passengers to make such a journey.

Earth, Sun, Andromeda galaxy and then the universe.

increasing size------------------------->

The Andromeda galaxy is visible to the naked eye in the night sky from fall to spring in the Northern Hemisphere. The best time to see it is during late autumn and early winter when it is high in the sky and away from city lights.

The Andromeda galaxy is approximately 2.537 million light-years away from Earth.

There is a new substantiated hypothesis that the universe is now expanding and contracting at the same time (here we go: nasha-vselennaia.ru/?p=10056) .

We think that some galaxies are moving away from us and some are approaching. The Andromeda is approaching to us with high speed (almost with the speed of light), but it falls into the black hole, at the center of which is our galaxy, the Milky Way.

Because of the great gravitational force between our galaxy and Andromeda, there is gravitational compression of time around us. That is, the time passes slowly around us, and it seems to us that Andromeda is approaching us slowly.

The closer it comes to us, the more will be the gravitational force and the time will slow down. We would think that the Andromeda is braking, slowing its approach, but it is actually approaching us almost at the speed of light.

We have nothing to be afraid of. According to our time, it needs billions of years to collide with our galaxy. If we really live in four-dimensional space, there is nothing surprising.

The Andromeda galaxy was discovered using a telescope. Specifically, it was first observed by Persian astronomer Abd al-Rahman al-Sufi in the 10th century using a basic refracting telescope. Subsequent observations have been made with more advanced telescopes to study Andromeda in greater detail.

The Andromeda galaxy is moving towards our Milky Way galaxy at a speed of about 110 km/s. This relative motion is causing the galaxies to slowly approach each other and will eventually result in a collision in billions of years.

About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.

In Greek mythology, Andromeda was a mortal princess known for her beauty and kindness, but she did not possess any supernatural powers. She was saved by the hero Perseus from a sea monster, and later became his wife.

The only real way to demonstrate this is to see Andromeda and all the local group of galaxies in one diagram sketch showing all of the proximities of the Milky way and it's satelite groups and all of the Andromeda satelite group of galaxies.

I can tell you that Andromeda is found about 20 widths of our galaxy away however I repeat you need to see this by drawing to comptemplate it. May i suggest you search for "Our Galactic Realm"

The Andromeda galaxy is a spiral galaxy, similar in shape to our own Milky Way galaxy. It is made up of a bright central bulge surrounded by a disk of gas, dust, and stars that spiral out in curved arms. From Earth, it appears as a fuzzy patch of light in the night sky.

With current technology, it would take hundreds of thousands of years to reach Andromeda Galaxy. The distance is about 2.537 million light-years away, making it impossible for humans to travel there in their lifetime using conventional means.
