What objects were once called nebulae?
Galxies were once thought to be nebulaes
What is a cluster of stars and a nebulae called?
its a constilalation
How many kinds of Nebula's are there?
*the correct term is nebulae. a nebulae is a could of many gases and dust, where stars are created. TYPES: Diffuse Nebulae- the most common type. it is interstellar, which means among the stars, and not part of any galaxy. Planetary Nebulae- completely unrelated to planets. planetary nebulae is when gas and plasma are formed after certain types of stars die. it sometimes looks like gas planets, like neptune and uranus, hence the name. Reflection Nebulae- clouds of dust that reflect the light of nearby stars, though they are not nebulae, because they do not create stars. Protoplanetary Nebulae- a point in the lifetime of an astronomical object (star). protoplanetary nebulae, or preplanetary nebulae, emit light, much like reflection nebulae Emission Nebulae- a could of ionized gas which emits colorful lights
What are two types of bright nebulae?
emission nebulae and reflection nebulae.
What are The Two types of bright nebulae?
emission nebulae and reflection nebulae.
How do stars get their enegry?
They get enegry by giant clouds of dust called nebulae.
What are the two main types of bright nebulae?
emission nebulae and reflection nebulae.
Do stars make a star?
A star is created once enough dust/gas gather up (called nebulae) and the gravity from a nearby star or shockwave from a nearby supernova causes it to contract. Once a star dies, it blows and becomes a nebulae again, recreating the entire process over and over again to repeat until the end of time. (unless the star becomes a black hole.)
What is a diffuse nebulae?
In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
Where are all-stars born?
From vast clouds of dust and gas called nebulae.
Is a meteoroid and a meteorite the same?
An object is called a meteorite once it has struck the ground; before that it's called a meteoroid
