What did our sun look like before it was a star?
The Sun (and all the planets) started their lives in a giant cloud of cold molecular gas and dust. And then about 4.6 billion years ago, something bumped into the cloud, like the gravity from a passing star, or shockwaves from a supernova, causing the cloud to collapse. With the collapse, the mutual gravity from the particles in the cloud pulled together, and formed pockets of denser material in the cloud. These were star forming regions, and one of them was to become the Solar System.
A very large cloud of gas in outer space is?
Called a nebula. It's mainly made from hydrogen gas and when it contracts under it's own gravity may eventually form a new star.
what causes a star to explode as a supernova?
Either somebody shoots at the star. Or kills the star turning it into a supernova.
How does Gravity play a role in the Death of a Star?
When a star runs out of energy, its mass is so great that the remaining energy cannot force the outer edges of a star away from its core, so the gravity causes the star to implode on itself.
Can condense and become concentrated enough to form a star and possibly planets?
A gas cloud. It must contain dust to form planets. (And lots of hydrogen to form a star.)
Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
What is the source of energy as a star evolves from an interstellar cloud to the protostar stage?
Gravity
Do protostars form when gravity causes dense parts of a star-forming nebulae to expand?
No. A protostar forms when gravity causes dense parts of a nebula to collapse. Since gravity is an attractive force it does not make any sense that it would cause something to expand.
What stage is a nebula?
A nebula is the initial stage in the lifecycle of a star, a vast cloud of gas and dust in space where stars are born. Gravity causes regions within the nebula to contract and form protostars, which eventually grow into full-fledged stars. Nebulas are the birthplaces of stars in the cosmos.
What creats a star?
Gravity is the force that causes stars to be created
What force causes a nebula to become a star?
Gravity and heat.

What forces cause the accumulation of matter that form stars?
Well what the problem is really adressing is what force causes the accumulation of matter or the nebulae to form stars. Simply gravity. The nebulae collapes due to a concentrated point of gravity. All that matter collapes into a star. So the answer is gravity.
What force creates a star?
Gravity is the force that causes stars to be created
Glowing gas clouds that will eventually become stars?
protostars That is called a Nebula. It is a giant cloud of gas, made up of various elements including hydrogen, helium and others. The clouds float in space and contain everything necessary to form a star and a solar system. Eventually something causes the gravity in the nebula to become unstable. For instance, shock waves from a super nova or something similar. These shock waves cause the cloud to start to move, which if strong enough, will cause the cloud to start spinning. Gravity takes over and eventually you have a star. This is a gross oversimplification. Much more happens than this. But it answer the question fairly quickly.
