Different types of benign, or noncancerous, adrenal tumors prove a frequent cause of enlargement of the gland. Adrenal adenomas remain the most common type of benign adrenal tumors, representing over 50 percent of adrenal masses. Uncommon benign adrenal tumors include adrenal cysts and lipomas, or fat-derived tumors.
The Sun provides the energy for the aurora, but particles in the. aurora come from Earthâs own neighborhood in space. The Sunâs. energy is carried toward the Earth in the solar wind, a stream of. electrically charged particles (mostly protons and electrons) ïow-. ing out from the Sun in all directions.
The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earthâs atmosphere and collide with gases such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern and southern hemispheres. Auroras that occur in the northern hemisphere are called âAurora Borealisâ or ânorthern lightsâ and auroras that occur in the southern hempishere are called âAurora Australisâ or âsouthern lightsâ.
