Why is the pleides called a steller nursery?
Pleiades is considered a stellar nursery because it is a dense region of stars and gas in our galaxy where stars are still being formed. Basically, Pleiades is a stellar-sized birthing place of stars.
What are the unique characteristics of a galaxy disc and how does it contribute to the overall structure of a galaxy?
The galaxy disc is a flat, rotating component of a galaxy that contains most of its stars, gas, and dust. Its unique characteristics include a spiral shape, a thin and dense structure, and the presence of young stars and star-forming regions. The disc contributes to the overall structure of a galaxy by providing the framework for the galaxy's spiral arms, influencing its gravitational dynamics, and playing a key role in the formation and evolution of stars within the galaxy.
What came first the sun or the stars?
Stars came first before the sun. Stars formed billions of years before the sun did as part of the process of galaxy formation. The sun is a relatively young star compared to many others in the universe.
Where are the ionization nebulae predominantly located in the galaxy M51?
Ionization nebulae in the galaxy M51 are predominantly located in the spiral arms of the galaxy. These regions are where massive, young stars are found, which emit high-energy ultraviolet radiation that ionizes the surrounding gas, creating the colorful nebulae. The ionization nebulae are often observed in regions of active star formation within the galaxy.
What is the color of a dying star?
The color of a dying star can vary depending on its size and age. Smaller dying stars tend to appear white or blue, while larger dying stars can appear red or even orange. The color is determined by the star's temperature and the chemical elements present in its outer layers.
Which type of galaxy is composed mostly of young stars?
The spiral galaxy's.
Young stars in the Milky Way Galaxy?
Yes, there are young stars in the Milky Way Galaxy.
Is this true an elliptical galaxy has mostly old stars?
Both - all galaxies contain young and old stars.
Match each galaxy to its description?
Milky Way: Arms extend from a core full of black holes Elliptical Galaxy: Contains mostly older stars with a red color Irregular Galaxy: Contains dust, gas, and young stars Apex :)
Is there a such thing as the Milky Way?
Yes: 1) THERE IS A CHOCLATE BAR THAT IS CALLED THAT AND IT IS VERY TASTY 2) WE LIVE IN THE MILKY WAY GALAXY IT IS A BARRED SPIRAL GALAXY AND IS MADE OF MOSTLY OLD STARS BUT ALSO YOUNG STARS
Contains dust gas and young stars?
irregular galaxy
What galaxy has the youngest stars?
Most new, young, stars can be found in the arms of spiral galaxies
What are young galaxy stars that have giant black holes at the center?
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
Explain how scientist know that elliptical galaxy do not contain many young stars?
Scientists know that elliptical galaxies do not contain many young stars because observations have shown that they have mostly older stars with low levels of interstellar gas and dust needed for star formation. This lack of gas and dust suggests that these galaxies have exhausted their supply of materials for forming new stars and are no longer actively forming young stars.
What is the difference between disk stars and halo stars?
Stars in the disk all orbit in the same direction and nearly the same plane, while halo stars have more randomly oriented orbits.Clusters of young stars are found only in the disk.Disk stars come in a broad range of masses and colors, while halo stars are mostly of low mass and red.Gas and dust are abundant in the disk but not in the halo.
Why do new stars form in the arms of a spiral galaxy and not in the central bulge?
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
What contains dust and gas and young stars?
A nebula contains dust and gas, which are the raw materials for forming new stars. Nebulae are regions in space where young stars are born from the gravitational collapse of these materials.
