With 12 new discovered moons Jupiter now has 79 moons

Jupiter, the fifth planet from our Sun and the largest planet in the solar system – more than twice as massive as all the other planets combined, has 79 moons including 12 new discovered moons.

On Jul. 17, 2018, scientists announced they had discovered 12 new moons orbiting Jupiter. That raised Jupiter’s total number of moons to 79—the most of any planet in the solar system. Fifty-three of the moons are confirmed and named; the other 26 are awaiting official confirmation of discovery before they are named.

Jupiter's four largest moons—Io, Europa, Ganymede and Callisto—were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope. These four moons are known today as the Galilean satellites, and they're some of the most fascinating destinations in our solar system.

Io is the most volcanically active body in the solar system.

Ganymede is the largest moon in the solar system (even bigger than the planet Mercury).

Callisto’s very few small craters indicate a small degree of current surface activity.

A liquid-water ocean with the ingredients for life may lie beneath the frozen crust of Europa, making it a tempting place to explore.

Some facts about Jupiter

One Day on Jupiter is about 10 hrs (9.92496 Hours). The shortest day in solar system.

Jupiter takes nearly 12 earth year (4,333 Earth days) to complete one orbit around Sun.

Jupiter is the biggest planet in our solar system with radius 43,440.7 miles (69,911 kilometers) which 11 times wider than earth

It is nearly 484 million miles (778 million kilometers), away from the Sun. For this distance, Sunlight takes 43 minutes to travel from the Sun to Jupiter.

It has the largest ocean in the solar system—an ocean made of hydrogen instead of water. This is due to the great pressure that squeezed off the hydrogen atoms.

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

STARS GOING OUT OF CONTROL

Stars Gone Haywire. As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Thanks to Hubble which give us a chance to view these beautiful stars. The Butterfly Nebula Imagine a lawn sprinkler spinning wildly, tossing out two S-shaped streams. At first it appears chaotic, but if you stare for a while, you can trace its patterns. The same S-shape is present in the Butterfly Nebula, except in this case it is not water in the air, but gas blown out at high speed by a star. The S-shape directly traces the most recent ejections from the central region, since the collisions within the nebula are particularly violent in these specific regions of NGC 6302. "This iron emission is a sensitive tracer of energetic collisions between slower winds and fast winds from the stars. It's commonly observed in supernova remnants and active gala...

WHAT IS A BLACK HOLE

In April, NASA created a big announcement that they captured first image of black hole. BUT WHAT IS A BLACK HOLE It is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole. HOW THEY ARE FORMED Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the total mass of the star is large e...
