She used her innate force powers. It was called the Mary Poppins force power. Supposedly Leia tapped into her force power almost out of instinct and that force instinct protected her in the vacuum of space and amazingly she didn't implode.
In the movie, Leia is sent hurtling into space after an attack on her ship. Just when it seems like all hope is lost, Leia is able to use the Force to pull herself through space and back to the safety of the ship. It was the first tacit moment where Leia displayed Force powers onscreen.
Since exogorths insulated themselves deep inside asteroids and their own heat-generating waste, Leia Organa, Han Solo, and Chewbacca were able to survive inside the space slug with only breath masks to provide oxygen.
So Leia isn't 'flying' or even floating really. All she really needs to do is apply a small amount of force to propel her in the right direction. She'll keep going until a force acts on her causing her to come to halt.
Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection. Vader's denial of Anakin Skywalker's legacy and his fear of getting hurt again prevented him from realizing the truth about his children until later in the original trilogy.
Thankfully, an astronaut being irretrievably stranded away from their spacecraft has never happened before. The first astronaut to float away from the safety of their ship without a tether was Bruce McCandless, who reached 320 feet away from the Challenger space shuttle on February 7, 1984.
Therefore, given that the plasma can be generated, it will function. There is no risk of short-circuiting in space as there would be underwater without augmentation. Plasma can materialize anywhere as long as it is hot enough, so it could exist in the vacuum of space.
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.
How long can you survive in outer space? Without a space suit, you'd lose consciousness in about 15 seconds, die after 90 seconds and freeze solid within 12 to 26 hours.
Many of the Expanded Universe stories take place after or in between the events of the movies, and follow the main characters as they grow and start families. Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin.
Kylo Ren dies on Kef Bir (the ocean moon of Endor) shortly after Rey deals a mortal wound during a lightsaber duel on the wreckage of the second Death Star. Though Rey Force-heals him, saving his life physically, this blow, coupled with the memory of his mother and father, destroys the man known as “Kylo Ren” forever.
Leia wanted to lead and reshape the galaxy, but wielding the same power that had corrupted Vader would be too big of a temptation because she would have become a powerful Jedi. So, it was safer to choose happiness, marry Han and avoid becoming a Jedi.
She utilized her lightsaber for sparring sessions during her time as her twin brother's first Padawan, and became immensely skilled with the blade. Soon after, in 5 ABY, Organa discontinued her training after she told Skywalker that she had sensed the death of her son at the end of her Jedi path.
Leia does not seem to react to tragedy. Instead, she has this wonderful ability to stay perfectly alert, reasonable, and careful of the feelings of others. She witnessed the destruction of her entire planet, and still had the mental and emotional strength to escape with Luke and Obi-Wan.
In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.
Zero gravity combat sounds fun, but it may be quite painful. The first punch might, because the assailant can't brace against the ground, so some of the momentum of his fist will be wasted pushing his body backwards.
The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny, lightwhips—a lightsaber variant with a flexible blade—were used to defend against Sith Lords who utilized the forms.
No, lightsabers can't block bullets. Here's a great video that explains why. The idea was actually put into issue #18 of the Dark Lord of the Sith comic series. During the hunt on Chandar's Folly, Tarkin's team armed up with slugthrowers (firearms) and flamethrowers, two things Vader couldn't block with his lightsaber.
Creating a lightsaber isn't a new idea by any stretch of the imagination, but doing it successfully has never actually been done, which means we're working entirely in the realm of the hypothetical.
Thankfully, this has never happened. While 21 people have died in space, spacecraft malfunctions that killed the entire crew, rather than health issues that affected only one person, have been to blame.
But the moniker of the "most terrifying space photo" is generally given to a photo of astronaut Bruce McCandless II, taken from the space shuttle Challenger on February 7, 1984.
