KELT-9b is a newly discovered giant planet which is hotter than many stars. The 4,315 degree Celsius hot planet, which is almost three times the size of Jupiter, revolves around a giant star named KELT-9. At 300 million years, the host star is a relatively young blue A-type star expelling so much ultraviolet radiation that KELT-9b is evaporating!”This is the hottest gas giant planet that has ever been discovered,” said Scott Gaudi, astronomy professor at The Ohio State University in Columbus, who led a study on the topic published in Nature magazine, as per NASA.The previously known hottest planet was WASP-33b, glowing at 3,200 degree Celsius and located in the Andromeda constellation– 380 light years away.(Source: NASA/JPLCaltech/R.Hurt/SWNS)Here is what you should know about the hottest planet in the known universe and its blue A-type host star:1. KELT-9b is situated 650 light years away from Earth, in the constellation Cygnus.2. The planet is 2.8 times bigger than Jupiter, but only half as dense.3. Scientists thought the radius of the planet to be smaller but the temperature of its host star is causing the planet to inflate like a balloon.4. The dayside temperature of the planet KELT-9b is more than 4,315 degree Celsius. KELT-9 star sizzles at 9,897 degree Celsius while our sun’s temperature is 5,600 degree Celsius. The star is also more than twice the size of Sun.5. The planet and its star are locked tidally as the earth and moon. So, one side of the planet always faces the star and the other side remains completely dark.advertisement6. The planet might sport a giant, glowing gas tail like a comet as it is being constantly hit by extreme radiation causing planetary material to evaporate.7. All known planets move around the equator of their stars but KELT-9b orbits around the poles of its massive star.8. KELT-9B also orbits its star at a much closer distance than between Mercury and Sun.9. The orbit of the planet is perpendicular to the spin axis of the star. One “year” on this planet is less than two days.10. Almost all the elements on the planet are in atoms, not in molecules and the atmosphere of the planet is essentially too hot for molecules to exist. So, methane, water, or carbon dioxide cannot form. Scientists presume that molecules might form on the nightside of the planet, albeit temporarily.”KELT-9 radiates so much ultraviolet radiation that it may completely evaporate the planet,” said Keivan Stassun, a professor of physics and astronomy at Vanderbilt University, Nashville, Tennessee, who directed the study with Gaudi.Why is this discovery significant?The scientists are usually interested in studying smaller and cooler stars, as there is more chance of finding planets with Earth-like habitable conditions. Still, the discovery of the weird atmosphere of the planet is quite intriguing. It is the hottest planet to be found till date, which might provide some insight as to how planetary systems form around extremely hot stars.The discovery was made using one of the two Kilodegree Extremely Little Telescope (KELT) telescopes at Arizona’s Winer Observatory trained to look at very bright stars at low resolution over broad areas of the sky. In contrast, other telescopes look at faint stars over small sections of the sky and in high resolution. Astronomers plan to look at KELT-9b using other telescopes like the Spitzer and Hubble space telescopes to gather more information.KELT telescope (Source: NASA)”Thanks to this planet’s star-like heat, it is an exceptional target to observe at all wavelengths, from ultraviolet to infrared, in both transit and eclipse. Such observations will allow us to get as complete a view of its atmosphere as is possible for a planet outside our solar system,” said Knicole Colon, the paper co-author who was based at NASA Ames Research Centre in California’s Silicon Valley during the time of this study.(Main image: NASA/JPLCaltech/R.Hurt/SWNS) Interested in General Knowledge and Current Affairs?

Ed. note: I asked my uniform Photoshop specialist Chris Knox to see if he could whip up some options for what the throwback uniforms OSU might wear on Thursday might look like.That’s a lot of mights but Knox did a tremendous job re-creating what a nod to yesteryear might look like. Here’s his take on a few different years with my commentary.1980I would weep. My gosh. If this is what OSU rolls out in on Thursday evening as a nod to 1980 I will lose it. The three stripes, the black and white helmet, all of it. Bring it on.1983Pretty similar to 1980 but I like the three stripes of 1980 a little bit better.1988These are good, not great. I would prefer a white-orange-white look if this is what OSU decides to go with.1992Another fantastic look and a nod to the three wins we posted from 1990-1998 (or something like that). I wouldn’t mind seeing these pants full time.If you’re looking for the comments section, it has moved to our forum, The Chamber.
