True. The gravitational force between two objects decreases with distance, and the vast distances between our sun and distant stars in other galaxies make their gravitational influence negligible. While gravity acts over infinite distances, the effects become incredibly weak at such scales, making it difficult to perceive any significant gravitational interaction.
True
Einstein's cross is located about 8 billion light-years away from Earth. It is a gravitational lensing phenomenon where the light from a distant quasar is bent by the gravitational field of a foreground galaxy, creating multiple images of the quasar.
The gravity of the galaxy's mass, primarily from stars, gas, dust, and dark matter, is responsible for holding these components together. The gravitational attraction between these elements counteracts the outward pressure from stellar processes and cosmic expansion, maintaining the galaxy's structure. Additionally, dark matter, which does not emit light, contributes significantly to the overall gravitational field, further binding the galaxy's mass.
The Andromeda Galaxy is a distant spiral galaxy located about 2.537 million light-years away from Earth. It is the nearest spiral galaxy to our Milky Way.

No. It's the mutual gravitational force between it and the earth that keeps a satellitein a closed orbit, instead of flying off away from earth in a straight line.Technically, there's no such thing as "outside of" the gravitational force of anything.We can calculate the gravitational force between a star in a distant galaxy and the earth.In fact, we can calculate the gravitational force between a star in a distant galaxy and you.The force is pretty small, but it's there.
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
Gravitational lensing is a phenomenon where light from a distant object is bent and distorted by the gravitational field of a massive object, such as a galaxy or a cluster of galaxies, that lies in between the distant object and the observer. This bending of light can create multiple images of the distant object, distort its appearance, or even magnify it. Gravitational lensing is a powerful tool for studying the distribution of dark matter in the universe and for discovering distant galaxies and objects.
Yes. Lensing magnifies the image of galaxies behind distant galaxy clusters but also greatly distorts the image.
Everywhere is all the things which are visible and visible around you. This can be a home, another country, or a distant galaxy.
Yes, furthest the galaxy more it's speed of moving away from each other also universe is expanding continuously therefore space between galaxies is also expanding . Redshift is directly proportional to the distance b/w the galaxies therefore distant galaxies red-shifted at faster rate
A satellite galaxy is one that revolves around another galaxy.
Yes, all objects with mass exert a gravitational force on each other regardless of the distance between them. This force follows the universal law of gravitation, which states that the force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. This explains why the sun and a star in another galaxy can still feel each other's gravitational pull, even if they are very far apart.
They are red shifted.
The Galaxy, also call the Milky Way, is made of stars. Other, distant star systems are called galaxies (lower case g) by analogy.
There are distant galaxies all around us - in all directions, and at varying distances.
