ROLE OF COMPUTING. “Large-scale or global models of the coupled solar wind-magnetosphere-ionosphere system have advanced greatly in the recent past, both due to better understanding of the critical processes and due to the increased computational capabilities.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

THE STAR HD 195689, “also known as KELT-9, is 2.5 times more massive than the sun and has a surface temperature of almost 10,000°C. Its planet, KELT-9b, is much closer to its host star than Mercury is to the sun.” https://theconversation.com/the-seven-most-extreme-planets-ever-discovered-78959 View in LinkedIn

HD 149026b. “This boiling world is one of the hottest and densest ever found. None too pleasant to visit, the surface of the planet is about 3700 degrees Fahrenheit (more than 2,000 degrees Celsius) — about three times hotter than the surface of Venus, the hottest planet in our solar system. HD 149026b is so hot that scientists think it absorbs almost all of the heat from its star, and reflects almost no light. The scorching ball is smaller than Saturn, but has a core that weighs 70 to 90 times the mass of the entire Earth.” https://lnkd.in/dDZa-gH View in LinkedIn

EXTREME PLANETS tend to present with any of the following characteristics: extreme heat, coldness, magnetic properties, density, gravity winds, toxic atmospheres and charged particle fluxes. And the presence of exotic matter called plasma. In most cases, these are many fold greater than found on Earth. We have only just scratched the surface of these planets in our near-observable universe. There will, undoubtedly, be more. View in LinkedIn

MORE ON NEPTUNE WINDS. “Neptune has the strongest winds in the Solar System. Winds whip clouds of frozen methane across the planet at speeds of more than 1,200 miles per hour (2,000 kilometers per hour). This is close to the top speed of a U.S. Navy F/A-18 Hornet fighter jet! The most powerful winds on Earth reach only about 250 miles per hour (400 kilometers per hour). https://lnkd.in/ddpsRdK View in LinkedIn

JUPITER. “The stronger the magnetic field, the larger the magnetosphere. Some 20,000 times stronger than Earth's magnetic field, Jupiter's magnetic field creates a magnetosphere so large it begins to avert the solar wind almost 3 million kilometers before it reaches Jupiter. The magnetosphere extends so far past Jupiter it sweeps the solar wind as far as the orbit of Saturn.” https://lnkd.in/deW2BUt View in LinkedIn

MAGNETIC BUBBLES. “Space may seem empty, but it’s actually a dynamic place populated with near-invisible matter, and dominated by forces, in particular those created by magnetic fields. Magnetospheres — the magnetic fields around most planets — exist throughout our solar system. They deflect high-energy, charged particles called cosmic rays that are spewed out by the Sun or come from interstellar space. Along with atmospheres, they happen to protect the planets’ surfaces from this harmful radiation.” https://www.nasa.gov/feature/goddard/2017/nasa-investigates-invisible-magnetic-bubbles-in-outer-solar-system/ View in LinkedIn
