Supernovae are very bright and generate bursts of radiation that can briefly outshine a whole galaxy before declining in brightness over many weeks or months.n this period a supernova can emit as much energy as the Sun might over its entire lifetime. How Supernovae are Studied. By using optical telescopes, astronomers can approximate the amount of light generated by a supernova.
What are hand cramps? Cramps in your hand can arise from a number of different causes. Hand cramps develop as a result of conditions affecting muscles and nerves in your hand. Trauma or injury to a nerve in your hand can also cause hand cramps. Even breathing too fast (hyperventilation) can result in hand cramps, as carbon dioxide levels in the blood become too low. Everyday, simple reasons, such as fatigue from overuse, can lead to temporary, acute cramps in the hand.
