STARS
The answer is simple: gravity.
a region of burning gases
It is due to surface tension. Surface tension is only for liquids. Due to surface tension surface energy is to be minimized only reducing the area. For a given volume sphere has minimum surface area. Hence spherical shape.
The sun
Greenhouse gases, like Carbon dioxide (CO2).
The answer is simple: gravity.
Gases are not restricted by gravity, so the molecules fly around, rather than stick together.
Yes.
A Nebula! :D!
a region of burning gases
In outer space, gases stay together due to the force of gravity. Gravity pulls gas particles towards each other, causing them to form clouds, stars, and galaxies. The balance between the outward pressure from gas particles and the inward pull of gravity helps maintain the shape and structure of these cosmic objects.
there are so many gases
A protostar forms when gravity pulls the dust and gases in a nebula together.
No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.

gasses
Yes, gravity plays a significant role in preventing gases from escaping a planet's atmosphere. The strength of a planet's gravity determines the escape velocity required for gases to break free from the planet's gravitational pull. Planets with higher gravity, like Earth, are able to retain gases more effectively compared to those with weaker gravity.
