The Orion nebula m 42 is a hot thin cloud of glowing gas so its spectrum is?
The spectrum of the Orion Nebula (M42) would show emission lines typical of hot, ionized gas, such as hydrogen-alpha and doubly ionized oxygen. This is because the gas in the nebula is being energized by nearby hot stars, causing it to emit light at specific wavelengths.
A nebula begins the process of becoming a protostar when the nebula?
begins to collapse under its own gravity due to a disturbance, such as a shockwave from a nearby supernova. As the nebula collapses, it heats up and the particles within it start to come together, initiating the formation of a protostar.
What is the horse head nebula?
The Horsehead Nebula is a dark nebula located in the constellation Orion. It is a cloud of dust and gas that is backlit by a nearby bright star, giving it the distinctive shape that resembles the head of a horse. The nebula is a popular target for astrophotography due to its striking appearance.
What color will an interstellar gas cloud composed of hydrogen glow?
It all depends on how close stars are to the cloud, and how intense those stars radiate energy. A nebula will glow with a blue colour if it simply reflects starlight (the blue is from the same mechanism our sky is blue, from the scattering of light). This occurs when a nebula is too far from stars, or the stars are too cool to generate enough radiation to ionize the hydrogen. Nebula will glow red if they are close enough to stars to absorb energy - that energy is re-emitted by the nebula as red (from the ionization of the hydrogen, which then glows red).
Cloud of dust that becomes a star?
A cloud of dust that becomes a star forms through the process of gravitational collapse. As the dust particles come together, they begin to heat up and eventually ignite nuclear fusion, which results in the birth of a new star.
What is emission nebula?
a type of nebula
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
What is an emission nebula?
An emission nebula is a type of nebula that glows and emits light due to the ionization of gases by nearby stars. These nebulae typically have a reddish hue from hydrogen gas and can be found in regions of active star formation. They are often characterized by their intricate and colorful shapes, such as the famous Orion Nebula.
What does a nebula contain of high density?
A nebula of high density contains mostly gas and dust particles. As gravity causes these particles to clump together, they can eventually form stars or other celestial bodies. High-density nebulae are often stellar nurseries where new stars are born.
What is the connection between pulsars and the Crab Nebula?
Pulsars were discovered in the Crab Nebula, a supernova remnant, in 1967. The Crab Pulsar is a neutron star at the center of the nebula that emits beams of radiation, producing regular pulses of light. The high-energy particles and magnetic fields in the nebula power the pulsar's emission.
Is a nebula a star?
a nebula is cloud of particles which forms into a star.
Which constellation is home to the Lagoon Nebula?
The Lagoon Nebula is located in the constellation Sagittarius. It is a prominent emission nebula and can be seen with the naked eye from a dark location.
What is the difference between a planetery nebula and a nebula?
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas
Are particles in the nebula attracted to one another because of gravity?
Yes, particles in the nebula attracted to one another by gravity?
What does a nebula form from?
Dust and particles.
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)
Orion is not the only nebula in space this is another one that is the name of a bird that rhymes with fawn?
The nebula you are referring to is likely the Swan Nebula, also known as the Omega Nebula. It is a famous emission nebula located in the constellation Sagittarius. The name "Swan Nebula" comes from its resemblance to a swan when viewed in certain images.
