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

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

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

COLDEST PLANET. “At a temperature of just 50 degrees above absolute zero – -223°C – OGLE-2005-BLG-390Lb snatches the title of the coldest planet.” https://lnkd.in/darr44x View in LinkedIn

WASP-189b temperatures “are enough to melt all rocks and metals, and even turn them into a gaseous form. It is not quite as hot as the surface of our Sun (6,000 degrees Celsius or 10,832 degrees Fahrenheit), it's basically as toasty as some small dwarf stars.” https://lnkd.in/dyZ3niw View in LinkedIn

WASP-121b. Nine-hundred light-years from Earth, there's a football-shaped planet so hot that heavy metals boil through its atmosphere, venting into space. The planet is about 10 times hotter than any other known exoplanet, due to its proximity to its host star, which is hotter than the sun. This proximity also gives the planet its unique shape, because gravitational tidal forces in its atmosphere elongate the whole planet.” https://lnkd.in/d3b5Rts View in LinkedIn

THE UNCERTAINTY PRINCIPLE. “Suppose you have an ice bucket containing H2O. You don't know whether the water is in the form of liquid or ice cubes, and you're not allowed to look into the bucket. So you try an experiment to find out. You grab a pair of tongs and stick them into the bucket, and out come ice cubes. But if you dip in a ladle, you get liquid water.” https://lnkd.in/g-p9M-4 View in LinkedIn

JUST STAMP COLLECTING is a criticism that can be leveled at the descriptive nature of astronomy, which is accumulating basic information with spanking new tools in the absence of grand schemes and broad theories. This criticism has been leveled at biology for the same reasons. But it is a natural developmental stage of a data heavy science. With this in mind, we will look at a range of extreme planets and stars. View in LinkedIn
