NASA scientists, using the Spitzer Space Telescope, announced the discovery of the hottest extrasolar planet found to date

The NASA Spitzer Space Telescope recently discovered gas planet HD 149026b, the hottest planet ever discovered. University of Central Florida astronomers, led by Joseph Harrington, found that the planet is 3,700F, a temperature higher than many low-mass stars.

The planet is a “hot Jupiter,” meaning that it is a large gas giant that rotates closely around its star. HD 149026b is located in constellation Hercules, up to 279 light-years away from Earth. While similar in size to Saturn, it has a core that is 70 to 90 times the mass of Earth, and the planet is able to complete a full revolution around its star in 2.9 days.

The telescope was able to estimate the temperature on the planet by monitoring the decrease of infrared after the planet dips around its star. It is likely that HD 149026b does not spread its heat around the planet. “The day side is very hot, and the night side is probably much colder,” said Harrington.

"This planet is off the temperature scale that we expect for planets," said Drake Deming, co-author for the paper, and a researcher at the NASA Goddard Space Flight Center.

Along with being the hottest planet ever discovered, the planet does not reflect a high amount of starlight, instead absorbing it – meaning HD 149026b is also the blackest planet known.

Scientists are trying to create a climate map of a “typical” gas giant. The recent discovery will help scientists learn about dense, gas giants that are not located in Earth's solar system.

The findings are available in the May 9 edition of Nature.

You are blind beyond all reason if you think that things are not getting worse. And yes im being dead serious. You ask around about this. Before the late 70's, people didn't have to lock the doors on their homes and cars. People didn't come to school and cowardly murder 30 unarmed students.

Charles Manson, Al Capone, the Harp boys.

Yeah, insanity is a result of modern science.

NOT.

Some people didn't lock doors back then because they were naive and had "faith". They still died.

School shootings have happened ever since both guns and public schools have existed.

Just because you don't know doesn't make it not true.
