What is the most abundant gas in emission nebulae?
The most abundant gas in emission nebulae is hydrogen. In these regions, hydrogen atoms are ionized by the intense ultraviolet radiation from nearby hot stars, causing them to emit light, primarily in the form of the characteristic red hue of H-alpha emission. Other elements, such as helium and traces of heavier elements, are also present but in much smaller amounts compared to hydrogen.
What is the two most abundant elements in the nebulae?
The two most abundant elements in nebulae are hydrogen and helium. These elements make up the majority of the mass in interstellar clouds and are the building blocks for the formation of stars and planets.
What are the different kinds of nebula found in outer space?
There are several types of nebulae found in outer space, including emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae are clouds of ionized gas that emit light, reflection nebulae reflect light from nearby stars, dark nebulae are dense clouds that block light, and planetary nebulae are the remnants of dying stars.
Where are you most likely to find an ionization nebula in the galaxy?
Ionization nebulae are most commonly found in regions of active star formation, such as stellar nurseries like the Orion Nebula in the Milky Way. These nebulae are energized by the ultraviolet radiation emitted by hot, young stars, causing the surrounding gas to ionize and emit colorful light.
What gas is the most common in nebulae?
The most common gas in nebulae is hydrogen. Hydrogen makes up about 90% of the atoms in the universe and is the building block for stars and galaxies. It emits light in the red part of the spectrum, creating the characteristic pink or red glow of many nebulae.
What are two elements which are abundant in nebulae?
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
What is the two most abundant elements in the nebulae?
The two most abundant elements in nebulae are hydrogen and helium. These elements make up the majority of the mass in interstellar clouds and are the building blocks for the formation of stars and planets.
What is the third most abundant element in the Milky Way Galaxy?
The third most abundant element in the universe is Oxygen.
Why is the milky way similar to other galaxies?
For one thing, the Milky Way is a spiral galaxy, which is the most abundant type of galaxy.
Milky white mineral made of silica?
A milky white mineral made up of silica is quartz. Quartz is the second most abundant mineral on the Earth's crust.
What are the different kinds of nebula found in outer space?
There are several types of nebulae found in outer space, including emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae are clouds of ionized gas that emit light, reflection nebulae reflect light from nearby stars, dark nebulae are dense clouds that block light, and planetary nebulae are the remnants of dying stars.
Can Nebula exist only within your galaxy?
No, nebulae are not unique to the Milky Way, there are hundreds that have been identified outside it, and are generally assumed to be present in most if not all other galaxies.
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

Are Bok globules same as Nebulae?
They are the smallest manifestations of dark nebulae with sizes less than 3 light years across, and are most easily visible when silhouetted in front of emission nebulae or reflection nebulae. Though upper limits are difficult to decide, they generally contain between 0.1 and 2000 solar masses of gas and dust (above this they are simply known as dark nebulae), and form isolated stars, not massive star clusters. Bok Globules typically have temperatures of around 10 Kelvin.
Why is hydrogen emission useful in mapping the arms of the milky way?
Because hydrogen is the most common element in the universe and also it has a spectral emission line in the microwave radio part of the spectrum making it easier to track with a radio telescope.
Are nebulae and constellations found within galaxies?
constellations are actually pictures that the stars seem to be arranged in from particular point of view, while nebulae are places where stars form. Both the Orion Nebula and the stars in the constellation Orion are visible from Earth, and both are in the Milky Way Galaxy, of which we are also a member. In fact, most things that you see in the night sky are part of our galaxy.
