What else can I help you with?
Which is the correct order in this secuence of events Big Ban Formation of galaxies formation of sun formation of earth?
Big Bang, formation of galaxies, formation of sun, formation of earth.
What has the highest rate of star formation?
Starburst Galaxies
What is the primary force involved in the formation of galaxies after the big bang?
Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.
What galaxies are smaller with many bright young stars and lots of gas and dust for star formation?
Spiral Galaxies
What cosmic accident is believed to form many irregularly shaped galaxies?
Collisions or interactions between galaxies are believed to be the cosmic accidents that can lead to the formation of many irregularly shaped galaxies. These interactions can trigger bursts of star formation and distort the shape of galaxies, resulting in the formation of irregular shapes.
What role do particles in the universe play in the formation and evolution of galaxies?
Particles in the universe, such as hydrogen and helium, play a crucial role in the formation and evolution of galaxies. These particles come together through gravity to form stars, which then group together to create galaxies. The interactions and movements of these particles shape the structure and behavior of galaxies over time.
How are galaxies influenced by their surroundings?
About the only thing that can surround galaxies is other galaxies. Since many galaxies appear to lie in approximate lines, one thing that influences galaxy formation may be "superstrings," but these have yet to be directly detected.
Which formation theory suggests that galaxies formed when massive Protogalactic cloud fragmented into smaller gas clouds that then formed into individual galaxies?
The formation theory that suggests galaxies formed when massive protogalactic clouds fragmented into smaller gas clouds is known as the "top-down" model of galaxy formation. In this model, the initial large structures collapse under gravity, leading to the creation of smaller, individual galaxies as these gas clouds cool and condense. This theory contrasts with the "bottom-up" model, where smaller structures merge to form larger galaxies over time.
What galaxies are massive blobs of stars?
Elliptical galaxies are massive blobs of stars characterized by their round or ellipsoidal shapes. These galaxies are composed mainly of older stars and have little to no ongoing star formation activity.
Galaxies shaped like footballs are blank galaxies?
Galaxies shaped like footballs are known as elliptical galaxies. They typically have an elongated, oval shape and lack the distinct structures, such as spiral arms, found in spiral galaxies. Elliptical galaxies can vary in size and brightness, and they often contain older stars with little ongoing star formation.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
What type of galaxie is smaller and fainter than other galxies?
Dwarf galaxies are smaller and fainter than other types of galaxies. They typically contain fewer stars and have lower luminosity compared to larger galaxies like spiral or elliptical galaxies. Despite their size, dwarf galaxies can be important for understanding galaxy formation and evolution, often serving as satellites to larger galaxies.
