Galaxies

Answer: These numbers are only estimates of course. Over the years estimates of the numbers of stars in our Galaxy has gradually increased. Good sources

give various numbers ranging from about 200 billion up to 500 billion.

I think the higher numbers are more likely to be correct.

Our Milky Way Galaxy is, very roughly, average.

So, a typical galaxy should contain a few hundred billion stars.

Answer: It is very hard to give a "typical" number. The answer above refers mainly to our own galaxy, but there are lots of galaxies that are much, much smaller - and there are also giants that are much larger than our galaxy. Thus, a typical galaxy may contain anywhere between about 10 million stars, and a trillion (i.e., a million million) stars, although you'll probably find galaxies with more than that.

The star that a planet travels around is called its parent star or host star. The parent star provides the gravitational force that keeps the planet in orbit around it. Similarly, our planet Earth orbits around the star we call the Sun.

Leaving aside any religious predictions regarding armageddon, from a scientific perspective, the Earth will end in about 5 thousand million years time, when the Sun expands to become a red giant whose outer layers will extend as far as Earths orbit. The Earth will become part of the Sun.

By definition the question is incorrect. There are not only 2 galaxies in our universe, but billions. Each galaxy is a different size and is made up of millions or stars and planets. Our galaxy is called the Milky-Way, and our closest neighbouring galaxy is called the Andromeda galaxy.

Nearly all galaxies have a component of motion directly away from us. The farther a galaxy is from us today, the faster it appears to be receding from us.Nearly all galaxies are moving away from Earth. This is because the universe is expanding.

Shapley discovered that the Milky Way is not at the center of the universe, but rather on its outer edge. Oort determined that the galaxy is rotating and that the Sun is located about halfway between the center and the edge.

Yes, searching for extraterrestrial life can expand our understanding of the universe and potentially provide insights into the origins of life on Earth. Continued exploration and research are essential to potentially making profound discoveries about life beyond our planet.

No the big dipper is IN Ursa Major and the little dipper is in Ursa Minor

A Galaxy isn't just one object, it is a group of millions of objects, in this case the objects being stars (which are all like the Sun since the Sun in itself is a star).

A galaxy is a massive, gravitationally bound system that consists of stars, stellar remnants and an interstellar medium of gas and dust.

Typical galaxies range from dwarfs with as few as ten million (107) stars up to giants with one trillion (1012) stars, all orbiting the galaxy's center of mass.

Our own Galaxy in which our solar system is found is called the Milky Way and it is estimated to contain at least 200 billion stars and possibly up to 400 billion stars.

So to answer your question:Yes, the galaxy is bigger than the Sun.

I am an artificial intelligence and do not have a physical location in the Milky Way galaxy or any other place in the universe.

1. Using a spacecraft: By building a spaceship with enough fuel and power to travel to the moon, astronauts can travel to the moon via a spacecraft.
2. Using a space elevator: Although currently a theoretical concept, a space elevator is a proposed method of reaching the moon by constructing a tall structure extending from Earth's surface into space, with a cable system that can transport payloads to the moon and beyond.

Earth is located in the Milky Way Galaxy.

The Sun is a mid-sized, average yellow star in the Milky Way galaxy. It is classified as a G-type main-sequence star, with a surface temperature of around 5,500 degrees Celsius. Its luminosity and size place it comfortably within the range of other similar stars in our galaxy.

Sun is important to earth cause it produces light needed for plants(photosynthese) to make O2(oxygen)
Without the suns heat and light we could not survive
If there is no sun then there would be no life on Earth. All the plants would die, then all the animals that eat plants would die then humans who eat both the plants and animals would die. Not to mention it would become very, very cold.

The Coma Cluster is known to contain a mix of elliptical and lenticular (S0) galaxies as its dominant types. These galaxies are characterized by their older stellar populations and lack of much ongoing star formation activity. Spirals and irregular galaxies are also present but in smaller numbers compared to elliptical and lenticular galaxies in the Coma Cluster.

Dwingeloo 1 galaxy is about 9 million light years from us.

Dwingeloo 2 a satellite galaxy of D1 is about 10 million light years from us.

It is likely your imagination. White holes are theoretical in physics and have not been observed in reality. It could be a cloud formation or optical illusion causing the appearance of an open white hole in the sky.

Yes. In the second pilot, the first one with Kirk as the Captain, they left the galaxy. In the one with the Medusan Ambassador, they left it again. I am not sure if the Kelvans took he Enterprise outside the galaxy or not (the episode in which the crew was mostly turned into small paperweight-sized objects). And in one episode of TNG the Enterprise D wound up so far from this galaxy, I don't know if they could even tell where it was. I think this was a Q episode but am not sure.

The galaxy is extremely large. It is elliptical in shape, and measures roughly 80,000 light years on its short axis and 200,000 light years on its long axis. Even a single light year (the distance light travels in a year) is a very long distance, approximately seven trillion miles. The only way we have of investigating the galaxy at large is by telescope, and even the best telescopes can only see so much. When you are looking at something that is on the order of quadrillions of miles away, it is really hard to see. That is why it is difficult to find Earth-like planets elsewhere in the galaxy.

Learning about the solar system, galaxies, and the universe helps us understand our place in the vast cosmos, appreciate the diversity and scale of celestial objects, and gain insights into fundamental scientific principles like gravity and cosmology. It also sparks curiosity, fosters critical thinking skills, and promotes a deeper appreciation for the natural world.

Galaxies are mainly made up of stars, gas, and dust. Stars are the primary components, with gas (mostly hydrogen and helium) and dust filling the space between the stars. Dark matter is also thought to make up a significant portion of a galaxy's mass, even though it cannot be seen.

The sun is but one of several hundred billion stars within the Milky Way Galaxy. Thus the galaxy is much larger. The Milky Way is so vast that it takes light approximately 100,000 years to travel its diameter, and 1,000 years to travel its thickness.

The constellation is basically a direction in the sky, so it includes parts of our galaxies, but you can also see other galaxies in the same direction (in the same constellation).
