five things that only happen on Jupiter – Latest News, Breaking News, Top News Headlines

Just yesterday we learned that one of the natural satellites of Jupiter emits radio signals.

This is not any kind of smart message, rather, a natural emission of radio waves, but either way, it’s always interesting to take a look at our huge neighbor.

Visit the largest moons in the Solar System

The Jupiter tourism agency could well use this slogan: Ganymede, the moon that emits radio signals is also the largest in the Solar System.

It is larger than Mercury and only slightly smaller than Mars.

With Io, Europa and Callisto, is part of the Galilean satellites, so called because they were discovered in 1610 by Galileo Galilei. Because of their size, they are easy to observe with common optical telescopes.

Ganymede is special not only because it is the largest moon in the neighborhood, but it is also the only natural satellite that has a magnetic field of its own; by the way, that’s one of the things that explains why it emits radio waves.

Maximum gravity

On Jupiter, not only the moons are huge, the planet itself is the largest in the Solar System. It is 1300 Earths in size, although in reality it is not very dense.

Its mass is about 300 times greater than that of our planet, but that is so that the gravitational attraction on its surface is very large, compared to Earth, and with any of the planets in the Solar System.

Weight is the force with which the Earth attracts us, so if we travel to a place with less gravity like the Moon, we will feel lighter; so if we go to a place with more gravity like Jupiter, we would feel heavier, about three times more than here.

Oceans of metallic hydrogen

Jupiter is a giant composed mainly of hydrogen and helium, the two lightest elements in the periodic table, and in the Universe.

So really in that hypothetical trip we could not stand on its surface, because it is not solid.

It is thought that under that surface, due to the high temperatures and pressures, hydrogen could be in liquid and metallic state.

Although hydrogen is not a metal, it has been predicted that under certain conditions, such as those that exist on Jupiter, it could behave as such: conducting electricity.

Big red spot

It is the most easily identifiable feature of Jupiter in the images, although it does not always look exactly the same, because it is moving.

The spot is actually a meteorological event, what we here on our planet call anticyclone: a storm caused by a high pressure system.

As it is a dynamic event, its characteristics vary: it is currently twice the size of the Earth and it is estimated that it has winds of 400 km / h.

Long years, short days

We know that one year is the time when the Earth completes its return to the Sun, for us that is the succession of 365 days, approximately.

The farther away the planets are from the Sun, the longer they need to complete their full orbit: on Mars a year lasts almost 2 Earth years and Jupiter takes much longer: 12 Earth years.

On the other hand, the succession of days depends on how fast the planet rotates on its axis and Jupiter does it very fast: a day there lasts barely 10 Earth hours.

So without a doubt, we would have to organize very well to complete our daily tasks, if we lived there.
