Jupiter : the largest of the planets and fifth in order from the sun — Webster
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn, with the other two giant planets, Uranus and Neptune, being ice giants. Jupiter was known to astronomers of ancient times. The Romans named it after their god Jupiter.
Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet’s shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope. Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury. — Wikipedia

Million fold increase in the power of waves near...

Chorus waves are electromagnetic waves. Converted to sound they sound like singing and chirping birds at dawn. They can cause polar lights above the Earth as well as damage to satellites. Now, a team of researchers has found that such waves are intensified million-fold around Jupiter's moon Ganymede. This study provides important observational constraints for theoretical studies. […]

Astronomers have detected a possible planetary-mass object with a surprisingly powerful magnetic field some 20 light-years from Earth. It can help scientists better understand magnetic processes on stars and planets. […]
More mysteries of metallic hydrogen

Liquid metallic hydrogen is not present naturally on Earth and has only been created in a handful of places. Now scientists are researching the properties of liquid metallic hydrogen to understand how planets both inside and outside our solar system form magnetic shields. […]

The discovery of a dark ribbon of weak hydrogen ion emissions that encircles Jupiter has overturned previous thinking about the giant planet's magnetic equator. […]
Finding a planet with a 10 year orbit in just a...

To discover the presence of a planet around stars, astronomers wait until it has completed three orbits. However, this effective technique has its drawbacks since it cannot confirm the presence of planets at relatively long periods. To overcome this obstacle, astronomers have developed a method that makes it possible to ensure the presence of a planet in a few months, even if it takes 10 years to circle its star. […]
