This week, Jupiter is the brightest object in the evening sky

All observers in the Northern Hemisphere will notice, this week, with the naked eye, the planet Jupiter, which will become the brightest object in the evening sky. Jupiter will be visible even in the big cities with the worst light pollution. During this period, Jupiter will be even brighter than the star Sirius, which is usually the brightest.

Those who have binoculars could see at least one of Jupiter’s moons clearly. A telescope will be able to show all four of Jupiter’s moons: Io, Europa, Ganymede, Callisto.

  These moons of Jupiter were the very first objects to be discovered by Galileo Galilee in 1609. They were the proof to Galileo’s theory: the moons revolve around plants and planets themselves revolved around the sun.

Moons of Jupiter can be easily seen with binoculars or telescope if they not in front of or behind Jupiter which is very bright. Those who want to observe more details, you can use a powerful telescope, it will help you to see the bizarre atmosphere of Jupiter. Because of Jupiter’s rapid rotation (once every 10 hours), the clouds are forced into huge horizontal jet streams.

  The most interesting detail is the famous Great Red Spot, which is actually an oval cyclone, three times bigger than our planet.

This “Storm” has been tracked in Jupiter’s atmosphere for three centuries, the oldest and largest storm in the solar system. Red spot tends to drift east or west over time, so astronomers must always know its current longitude in order to observe it.
