Earth scientists assume that all this magnetic activity is to blame for the oddly intense heat of the corona, but heating up the corona to a hundred million kelvin—hotter than the core of the sun itself—a major solar Care releases only deadly amounts of radiation: lethal X-rays and gamma rays streaming through the system.

What is the meaning of the phrase in bold, please? And, why the word "Care" is written in the capital letter? Thank you.
