Hibernation


In cold areas, animals use various survival techniques to survive through cold and harsh winter. Hibernation is one such technique used by animals like brown and black bears in mountains. Hibernation is a state when animals become inactive. During hibernation, their body temperature lowers and, they breathe slowly and their metabolic rate lowers. This whole process conserves their energy during the frigid winter.

Bears usually hibernate from mid-December into March or early April. Bears in mountains hibernate in natural caves in talus slopes, snow caves, and hollow trees and logs. Bears hibernation is different from the hibernation of other animals like squirrels and rodents and bats. Hibernation of these other animal is called "true hibernators". These animals take several weeks before they reach the state of inactivity. During the hibernation, these animals have a very low metabolic rate and their body temperature drops many degrees below normal. Before entering hibernation most animals eat a large amount of food and store energy in fat deposits in order to survive the winter.

Jupiter


Jupiter is the most massive planet in our solar system. It has four planet-sized moons and many smaller moons. Jupiter forms a kind of miniature solar system. Jupiter resembles a star in composition. In fact, if it had been about eighty times more massive, it would have become a star rather than a planet.

On January 7, 1610, using his primitive telescope, astronomer Galileo saw four small 'stars' near Jupiter. He had discovered Jupiter's four largest moons, now called Io, Europa, Ganymede, and Callisto. These four moons are known today as the Galilean satellites.

Io is the most volcanically active body in our solar system. Ganymede is the largest planetary moon. Ganymede is the only moon in the solar system known to have its own magnetic field. A liquid ocean may lie beneath the frozen crust of Europa. Icy oceans may also lie deep beneath the crusts of Callisto and Ganymede. In 2003 alone, astronomers discovered 23 new moons orbiting the planet Jupiter. This gives Jupiter a total moon count of 49. The numerous small outer moons may be asteroids captured by the giant planet's gravity.
