What is an antonym of nebula?
Since,Nebula is an interstellar cloud of dust, hydrogen gas, helium gas and other ionized gas so it's antonym can be clearness and brightness
What is nebula's magnitude?
The magnitude of a nebula varies depending on its distance from Earth and its intrinsic brightness. Nebulae can range from very faint to quite bright, with some being observable to the naked eye, such as the Orion Nebula (around magnitude 4). Most nebulae, however, require telescopes for observation and can have magnitudes ranging from about 6 to 20 or more. The specific magnitude of a nebula is often used by astronomers to classify and study its properties.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
How do you measure the distance from earth to a nebula?
There are actually a number of different techniques that are used to estimate the distances of various astronomical objects. You can study the spectrum of the light (or any electromagnetic emission) from that object, and determine how much of a Doppler red shift there is (it's almost always a red shift, very few objects are approaching the Earth) and since the general rate of expansion of the universe is known, we can determine from the size of the red shift how far away something is. If the nebula is associated with a Cepheid variable star, then from the rate of variation and the brightness of the star, we have another clue. And, if we observe the nebula at two different seasons of the year, when the Earth is at opposite sides of the solar system, we may be able to get some parallax for a geometrical calculation, but that depends upon how far away the nebula is; if it is extremely far away, we don't have enough parallax to do it.

What is the difference between the Helix Nebula and the Ring Nebula?
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.

What was the first planetary neblua found?
M27 (dumbbell nebula) the dumbbell nebula is also known as messier 27,M27 or NGC 6853 is a planetary nebula is in the constellation Vulpecula at a distance of about 1,360 light years. This object was descoverd by Charles Messier in 1764.At it's brightness of visual magnitude 7.5 and it's diameter of about 8 arcminutes,it is easliy visible in binoculars,and a popular observing target in amateur telescopes.

How do you calculate the distance of nebulae?
There are many ways to calculate distance at huge scales. One popular way is using a Cepheid within the nebula. A Cepheid is a very luminous variable star (a star that changes brightness). The changing of brightness tells us a lot about the distance by measuring the period (time) and the luminosity. See the related link for more methods.
