Metaphasic shield

Metaphasic shielding is a technology invented by Dr. Reyga, a Ferengi scientist, in 2369. It is capable of withstanding the pressure, radiation and energy of a star's corona. The technology was installed on the Shuttlecraft Justman, but Reyga was murdered by Takaran scientist Jo'Bril shortly before the shields were proven. Subsequently, Dr. Beverly Crusher successfully demonstrated the shield's effectiveness by piloting the Justman into the corona of the star Veytan.
