So I really love how the intro to Pacific Rim is, like, 90% plausible/whatever for the first two minutes. Massive tragedy in San Francisco, media and cultural response, blah blah blah
Then, completely straight-up, “So that’s when we decided to make giant robots.”
When life hands you lemons
you make giant robots

(Movies of jets from young stars at HubbleSite: here)
If you’re like me and maybe a little confused as to what you’re looking at, here’s some more detail (Yes, even Joe has to look stuff up sometimes):
As a star is formed from collapsing dust, ever increasing its density and energy, it begins to form a disk of dust and gas pulled in and rotated by its growing gravity. Perpendicular to this disk, like the tip of a spinning top, some gas is ejected away from the growing star in a high-energy jet. As this collides with interstellar gas, it gives off radiation, which we can observe with telescopes like Hubble.
To see the jets, we have to shift into the infrared and other spectra, as the radiation is outside normal human vision. These movies represent the first time we’ve seen the dynamics of the jets as opposed to still images. More info on protostellar jets here, you star-freaks.
