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
Emission nebula glow and reflection nebula reflect the light form other stars
it is plop of a difference
"Nebula" is a astronomical term for a cloud of gas and dust. "Nebulae" is the plural of "Nebula" and refers to more than one such cloud.
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
Well, darling, a nebula is a big ol' cloud of dust and gas in space, while the Crab Nebula is a specific nebula located in the constellation Taurus. So basically, it's like saying a nebula is a generic term for a cloud in space, while the Crab Nebula is a specific cloud that got its own fancy name. Hope that clears things up for ya, sugar!
There isn't 'an' Eagle Nebula. There is 'the' Eagle Nebula. This is just the familiar name for a large cloud surrounding the Open Cluster M16. Nebulae come in all conceivable shapes and sizes, so they are all different from each other!
Crab Nebula:Pulsar wind nebulaSupernova remnantRadius of 5.5 ly6,500 light years awayOrion Nebula:Diffuse nebulaStellar nurseryRadius of 12 ly1,244 light years awayEdit: M1, the Crab Nebula, is related to the death of a star. The Orion Nebula, M42, is relateted to the birth of stars.
The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
It's the length of time between two solar transits as observed from the planet's surface. That's typically close to the time the planet takes to make one complete axial rotation. In the case of Earth, the difference between the two is a bit less than 4 minutes.
Orion is a constellation made up in the minds of the ancients to represent "Orion" a hunter in mythology. The Orion Nebula is a diffuse nebula located south or Orion's belt. It is an area of extensive star formation. It is only called Orion Nebula as it is seen within the constellation of Orion. See related questions
A nebula is a vast cloud of gas and dust in space, while a protostar is a dense region within a nebula where gravity causes material to come together and heat up, eventually leading to the formation of a star. In essence, a protostar is a stage in the formation process of a star within a nebula.
A nebula contains stars and other matter; a supernova is just a large enough nova, or star that explodes at the end of its life cycle due to spent fuel
