Nebulae
A nebula refers to an interstellar cloud of dust, helium gas, hydrogen gas, and other ionized gases in outer space. There are several types of nebulae categorized according to how they were formed.

Because in that era they had a TIME MACHINE that they took and went back to the first era where the cavemen were fascinated by the machine that they killed them and stole it and went back to the third era and they took hostages back with them so yeah they did make it
What is the longitude and latitude of the Crab Nebula?
The Crab Nebula's longitude is 184.6 and its latitude is -5.80, in the third galactic quadrant.
What year was the nebular theory discovered?
The nebular theory was proposed in 1755 by the German philosopher Immanuel Kant and was further developed by French mathematician and astronomer Pierre-Simon Laplace in 1796.
Dark nebulae are formed when dense interstellar clouds of gas and dust block the light from background stars, creating a visible dark patch against the bright emission nebulae behind them. Gravitational forces can cause these clouds to collapse and form new stars within them over time.
What is the most important factor that causes matter in a nebula to form clumps?
I don't know but here is a pic of a ninja

What two things are needed to create an emission nebulae?
An emission nebula is created when hot, young stars emit high-energy ultraviolet radiation, which ionizes the surrounding gas, causing it to glow. Additionally, the gas and dust clouds within the nebula act as the raw material required for the formation of such structures in space.
Nebulae are important because they are the birthplace of stars. They are large clouds of gas and dust in space that can collapse under gravity to form new stars and planetary systems. Studying nebulae helps us understand the process of star formation and the evolution of galaxies.
Why is a spoon named like that?
Spoon is derived from Old English spón, meaning chip of wood (Compare Old Norse spann, sponnchip/splinter, spoon; Swedish spån a wooden spoon); possibly from Proto-Germanic spænuz, (compare Middle Low German spon wooden spatula); possibly from Proto-Indo-European spē length of wood (compare Greek σφήν [sphēn] wedge).
How long does it take for a tooth cavity to form?
The formation of a cavity depends of: 1- How much sugar is in the diet.
2- The person's hygiene.
3- The person's defense system. If a person has a low defense system in his mouth, has a poor diet and poor hygiene, a cavity can form within a few weeks.
What caused the nebula that formed our solar system to rotate?
1) The collapse is not bound to be perfectly symmetrical. Some pieces of matter will randomly move in one direction, or in another. The net result is that there is some rotation.2) Roughly speaking, anything that rotates will continue rotating.
What benefit do you get from studying interstellar gas and dust?
It helps you understand the fundamental concepts of quantum physiology of the cosmos as well as cereptal covalency
How are stars formed within a nebula?
Interstellar gas is inelastic. To compress it some event typically must occur. A supernova, for example, produces a shockwave that collapses interstellar gas, precipitating nearby star formation. Another force is gravity--we have seen stars form in the swirling wake of passing black holes.
When two nebula collide, we might infer star formation across the "impact zone," much as water droplets precipitate when a moist warm air mass collides with a cooler, denser mass of air.
Sorry, but this doesn't make sense!
For a start, 'nebulae' is plural. And Cygnus isn't in a nebula. Cygnus (like all the constellations) is just a name given to a region of sky that appears to resemble some object or other from the arrangement of its stars. None of the stars in a given constellation usually have any connection with the others. They just lie in the same general direction. Deneb, the brightest star in Cygnus, is over 1000 lightyears away, but close to it (in the sky!) we have 61 Cygni, which is one of the closest stars to us, at about 11 lightyears.
A constellation is a purely human construct, like (say) a country with its borders.
How is the meaning of the word nebula different today than it was before Hubble's discoveries?
"Nebula" means "cloud" [cf. "nebulous," meaning misty or uncertain]. At one time, it was though that those fuzzy lights in the night sky were patches of glowing gas, probably satellites of our Galaxy. Better ranging techniques eventually confirmed that those were other galaxies, so far away they we couldn't discern the individual stars.
Pre-Hubble, it would have been quite acceptable to speak of the "Andromeda Nebula." Now, only something we KNOW is a gas cloud can be called a nebula, the most common usage being for "planetary nebulae" which, to add further confusion to the uninitiated, aren't composed of planets.
