Testo Storyboard
Diapositiva: 1
Once upon a time, on a planet far, far away...
Me too! It's been too long
I'm so glad we finally found time to stargaze again!
Diapositiva: 2
Little do they know, their lives are about to change forever, all thanks to this guy
Diapositiva: 3
OW! A creepy spider just bit me! Help!
ACK! Same! Wait, Maybe we'll get super powers now...
Diapositiva: 4
A spider that has been injected with gamma radiation, and accidentally let out of the lab
Diapositiva: 5
Oh my goodness what was that?!
I don't know, but it was so bright!
Yeah, it was brighter than every other star combined! What could have caused something so bright?
Diapositiva: 6
It is I! The great alien God! You have both been bitten by a radioactive gamma-ray spider
What you saw was a gamma ray burst. Gamma ray bursts are the most powerful events in the universe
There are two types of gamma ray bursts, although both signal the existence of a black hole
Diapositiva: 7
Short gamma ray bursts are caused by either the collision of a neutron star and a black hole, or two neutron stars
Short gamma ray bursts last less than two seconds.
Diapositiva: 8
Long gamma ray bursts are caused by the collapse of giant stars into black holes.
These gamma ray bursts last longer than two seconds.
Diapositiva: 9
Woah, I had no idea that gamma ray bursts existed. That one must have been a short burst, it was only one second!
Me neither, let's keep stargazing and see if we see any more neutron star/black hole collisions or star collapses!
