A "nova". About 500 years ago, an observer watching the sky observed a new star where there had never been one visible before. (500 years ago, there were no street lights and the night sky was DARK. There wasn't much to do other than to look at the stars.)
Since the observer was in Europe and the educated classes all wrote in Latin, he called it a "nova stellarum", which is Latin for "new star". The name "nova" has stuck.
Now, of course, we know SO much more than they did in the middle ages, and now we know that the "new star" was actually the last gasp of a DYING star; a star too far away to be visible, flaring into temporary brightness as it exploded, and the glow fading as the explosion spread out.
If it burns up in the atmosphere, it is a meteor. If it manages to make it through the atmosphere and land on Earth, it is a meteorite. A really bright meteor is called a bollide.
No she did not appear in that episode.

Assuming you mean "outer space", those people are called astronomers.
It is called the Apollo spacecraft.
A star that explodes is called a supernova.

When a star explodes and destroys itself, leaving only a dense core behind, it is called a Supernova. The only other option is when a star goes nova, where only the outer body of the star explodes, but the stellar remnant remains in place.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).

Its blown into interstellar space - to enrich and mix with the gasses already out there.
The grainy texture on the sun's surface produced by numerous bright markings is called granulation. These granules are the tops of convection cells, where hot plasma rises and cooler plasma sinks in the sun's outer layer.
