The secret layer ?

[Jaskin]

Hello,
The following passage is from article on science.nasa.gov

Next April, for a grand total of 8 minutes, NASA astronomers are going to glimpse a secret layer of the sun.
Researchers call it "the transition region." It is a place in the sun's atmosphere, about 5000 km above the stellar surface, where magnetic fields overwhelm the pressure of matter and seize control of the sun's gases. It's where solar flares explode, where coronal mass ejections begin their journey to Earth, where the solar wind is mysteriously accelerated to a million mph.

It is, in short, the birthplace of space weather.

Researchers hope it is about to yield its secrets.

I have problem with understanding the last sentence.
Could you tell me what "it" and "its" in the last sentence refer to ?
Is "it" refers to the secret layer ?
Cheers,

Yes, it would seem to refer to the "secret layer".
