In a galaxy that is close to the size of the Milky Way, supernovas occur roughly every 50 years. Scientists predict, however, that a supernova happens around every second across the universe based on how many galaxies have been observed.
Larynx is also known as lungs. The word larynx is a medical term.
Larynx: A tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm (2 in.) long. It is part of the respiratory system and is located between the pharynx and the trachea. Humans use the larynx to breathe, talk, and swallow. Its outer wall of cartilage forms the area of the front of the neck referred to as the Adam's apple. The vocal cords, two bands of muscle, form a V inside the larynx.
