The same reason why most things happen; gravity. Every speck of matter in the universe attracts every OTHER speck of the universe with gravity. So a a large thin cloud of gas in space will, over time, become a smaller thicker cloud of gas. Given enough gas and enough time, the cloud will collapse under its own gravity to form a star, or a planetary system.
But if all the gas is attracted in all directions, why would it all fall together HERE, rather than OVER THERE - and since the gas is all over, why would it collapse at all? We think that the shock of a somewhat-distant supernova explosion begins the collapse process by pushing enough gas together for gravity to finally do its thing.

How many types of nebulas are there that are known?
There are primarily five types of nebulas: planetary nebulas, reflection nebulas, emission nebulas, dark nebulas, and supernova remnants. Each type of nebula has distinct characteristics and origins.
Are nebulas bigger than earth?
Nebulas are interstellar clouds consisting of dust, hydrogen, helium and other ionized gases. Nebulas vary in size, so some are bigger than Earth, and others are not.
Are all-stars formed by nebulas?
No, all-stars are not formed by nebulas. All-stars are formed from clouds of gas and dust called molecular clouds, which collapse under their own gravity to form a star. Nebulas are massive clouds of dust and gas in space, where stars are born.
Do nebulas absorb light?
Nebulas do not absorb light in the same way that solid objects do. Instead, they scatter and reflect light from nearby stars and emit their own light through ionized gases and dust particles. This creates the beautiful and colorful appearance we see in images of nebulas.
Are Nebulas Toxic?
Nebulas in outer space are not toxic as they are vast clouds of dust, hydrogen, helium, and other ionized gases. However, if you are referring to the Nebulas blockchain platform, then it is not inherently toxic either. Like any technology, its use and applications can have positive or negative effects depending on how it is utilized.
When did Nebulas Ray happen?
Nebulas Ray happened in 1994.

When was Nebulas Ray created?
Nebulas Ray was created in 1994.

What do nebulas have to do with stars?
Nebulas are clouds of gas and dust in outer space, and they are where stars are born. The gas and dust in a nebula can collapse under gravity to form new stars. Additionally, nebulas are often illuminated by nearby stars, making them appear as colorful and glowing formations in the night sky.
What four letter word has to do with nebulas?
Star
What do nebulas form?
The nebula forms into a protostar.
Are nebulas larger than supernovas?
Yes they are.
What are the release dates for The Universe - 2007 Nebulas 2-14?
The Universe - 2007 Nebulas 2-14 was released on: USA: 25 March 2008
About nebulas what are they?
a nebula is a cloud of gas dust in space.some nebulas are regains where new strars are being formed while others are the remaidings of dead or dying stars .
Do nebulas absorb light?
Nebulas do not absorb light in the same way that solid objects do. Instead, they scatter and reflect light from nearby stars and emit their own light through ionized gases and dust particles. This creates the beautiful and colorful appearance we see in images of nebulas.
