June 18, May 21, What is a nebula? Nebulae plural of nebula in context of universe are interstellar clouds that are made NOT of water vapors BUT of The veil nebula essay, helium, hydrogen and dust. Now that we know that a nebula is not an average cloud, it is time that we learn about 20 interesting nebula facts and try to get a better understanding of these interstellar clouds.

Nebulae are usually formed by gravitational collapse of gasses in the interstellar medium. The particles that collapse have their own gravitational attraction and they clump together to form these clouds.

They may stretch over hundreds of light years across. A light year is essentially the distance that light can travel in one year. Here is a quick calculation: Light covers a distance ofkilometers in a second. Let us trivially assume that we have a nebula in form of a perfect circle which usually never happens.

So, the maximum distance between two extreme points of the nebula will be its diameter. If our assumed circular nebula stretches only one light year across then, the diameter of the nebula will be 9,, kilometers. So imagine how big a nebula can be that stretches hundreds of light years across!

Nebulae are often referred to as star nurseries of the universe because stars often form inside the nebulae. We know that nebulae are ginormous but how do they look like?

The Veil Nebula is a cloud of gas and dust, which is about 1, light years away in the constellation of Cygnus. It is a large supernova remnant which is said to be exploded about 5, years ago. Space travel and space exploration. NASA ESA Hubble Space $ About this time last year I successfully imaged first NGC the Western Veil, AKA the Witch’s Broom Nebula and shortly afterwards NGC the Eastern Veil, which includes NGC AKA the Bat Nebula. In themselves they are both wonderful parts of the larger but perhaps more elusive (photographically speaking) Veil Nebula.

Nebulae have myriads of shapes. We know that stars can form inside nebulae but how? According to scientists, gas and dust inside these nebulae squash together under their own gravitational pull. As a result, the clouds start contracting and get denser.

The denser they become, the hotter they get. Eventually they become so hot that hydrogen present in them gets ignited and new stars comes to life. When a star forms inside a nebula, ultraviolet rays are emitted and the entire nebula is lit up, resulting in what is known as emission nebula.

The Orion constellation that we see has an emission nebula known as Orion nebula.

Apart from emission nebulae we have other types of nebulae known as the reflection nebulae. They are so named because they do not emit their own light.

They only reflect the light from the nearby stars. Reflection nebulae appear blue in color.

Witch Head Nebula 9. An interesting phenomenon is that presence of reflection nebula means the presence of an emission nebula somewhere close.The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own .
