Great Red Spot on JUPITER!!!

Fifth Planet from the sun???

Closest to Mars???

Largest planet within the Solar System???

Fourth Largest Object in the Sky???


Of course it’s JUPITER… Great Red Spot.. What is it??? Exploration Starts…

Scientists recently noticed a GREAT RED SPOT on JUPITER which is a persistent anticyclonic storm on the planet that lasted atleast 300 years.

The Red Spot is huge as the storm is large enough to be visible through earth based telescopes. The red spot is large enough to contain TWO or THREE PLANETS of EARTH’s SIZE.

Jupiter also has white ovals and brown ovals, which are lesser unnamed storms. White ovals tend to consist of relatively cool clouds within the upper atmosphere. Brown ovals are warmer and located within the “normal cloud layer“. Such storms can last hours or centuries.. Thus storm created big spot on the largest planet of our solar system.

Helium Rains in SATURN and JUPITER!!!

Hydrogen and helium are the two lightest and most common elements in the universe. Because of their ubiquitous nature, they are critical in cosmological nucleosynthesis and are essential elements of stars and giant planets. Hydrogen by itself in the observable universe provides clues to the origin and large-scale structures of galaxies.

However, scientists have struggled to determine what conditions are needed for the two elements to mix.

The simulation results are consistent with the idea that a large portion of the interior of Saturn has conditions such that hydrogen and helium phase separate. “This can account for the apparent discrepancy between the current evolutionary models for Saturn and observational data.”

In addition to being made mostly of hydrogen and helium, a characteristic of Jovian planets is that they radiate more energy than they take in from the sun. Various models of their evolution and structure have been developed to describe a relation between the age, volume and mass of the planet and its luminosity.

While this model works for Jupiter by modeling the energy radiation left over from its formation 4.55 billion years ago, it doesn’t exactly work for Saturn. Instead, the model seriously underestimates the current luminosity of Saturn.


So the researchers decided to try something different. They determined where helium and hydrogen mix as well as at what temperature they don’t mix.

It turned out the temperature where the two elements don’t mix is high enough that helium is “partially mixable over a significant fraction of the interior of the Jovian planets with the corresponding region of Saturn being larger than in Jupiter. “This, in fact, could change the current interior models of Saturn and Jupiter.”
