Why the space is dark in spite of billions of stars?
Because the universe is neither infinitely large nor infinitely old. If you need more details, look up "Olbers' paradox".
Earth the sun and billions of stars are contained within what?
Earth, the Sun, and billions of stars are contained within the Milky Way galaxy, which is a vast collection of stars, gas, dust, and dark matter. The Milky Way is a barred spiral galaxy, and it is just one of billions of galaxies in the universe. It spans about 100,000 light-years in diameter and contains hundreds of billions of stars.
Can stars be dark?
Stars emit light due to thermonuclear reactions happening in their cores. Therefore, by definition, stars are luminous and cannot be dark. However, some stars may appear dimmer to us based on their distance, size, or phase in their life cycle.
Galaxies are made up of billions of?
Galaxies are made up of billions of stars, along with gas, dust, and dark matter. These components come together to form vast systems that are bound together by gravity.
In space is it dark?
Yes! space is pitch black! however, because of the light of the stars,and especially the sun..... space is really glowing with light . but it is still dark in space .
What is the largest object in space that is not a planet or a star?
The largest object in space that is not a planet or a star is a galaxy. Galaxies are massive systems of stars, gas, dust, and dark matter held together by gravity. They can contain billions to trillions of stars and are among the largest known structures in the universe.
Why is Space black or dark?
the space between stars and planets has insufficient particles to reflect the light back to us.
What are galaxies mainly made of?
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.
What would it look like in outer space?
Very dark - very similar to looking up at the stars on a dark night.
What is a galaxy How many galaxies are there and how many stars does each galaxy hold?
A galaxy is a large system of stars, gas, dust, and dark matter held together by gravity. There are estimated to be billions of galaxies in the universe, each containing millions to trillions of stars. The exact number of galaxies and stars in the universe is still unknown due to the vastness of space and the limitations of current technology.
What a space contains?
Space contains various celestial objects such as stars, planets, asteroids, comets, and galaxies. It also includes vast amounts of dark matter and dark energy, which make up the majority of the universe's mass-energy content. Additionally, space is filled with radiation, cosmic rays, and interstellar gas.
What is an irregular luminous band of stars called?
An irregular luminous band of stars is called a "galaxy." Galaxies are massive systems of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. They come in various shapes and sizes and can contain billions to trillions of stars.
