Despite being so hot, the corona is less than a millionth as bright as the Sun. As you walk away from a bonfire, you feel less of its heat because you receive less energy due to the inverse square law. Why is the more distant corona so much hotter than parts of the Sun closer to...
as a result of the incessantly thermonuclear fusion processes that produce the energy the sun relies on. In general, the temperature decreases from the core to the photosphere and then increases towards the corona; however, the abnormally high temperature of the corona (~1 million kelvin) is st...
According to Illinois law, it's pretty simple - if someone outside of the car can see what you're doing, it's illegal. So if you're driving around with your pants off and someone catches a glimpse, you could be in hot water. And no, putting on a show for other drivers on the ...
Death Valley is unbearably hot each year, but other spots on Earth are feeling the heat, too. And surface temperatures can be 50 degrees hotter than the air.
BEIJING, August 29 (TiPost) – In 1908, Professor Heike Kamerlingh Onnes at Leiden University in the Netherlands first liquefied helium in the laboratory, refreshing the record of artificial low temperature to -269℃ (4.2 Kelvin). In 1991, Onnes measured the electrical conductivity of pure metals...
The corona can be seen best during a solar eclipse and in X-ray images of the sun. The temperature of the corona averages 2 million degrees Kelvin. Although no one is sure why the corona is so hot, it is thought to be caused by the sun's magnetism. The corona has bright areas (...
Therefore, scientists concluded that a black hole had passed between Earth and the object. Emitted Radiation When material falls into a black hole from a companion star, it gets heated to millions of degrees Kelvin and accelerated. The superheated materials emit X-rays, which can be detected by...

Presents a history of the thermometer invented by physicist Lord William Thomson Kelvin in 1848. Scale proposed by Kelvin that would have at its lowest extreme the temperature that results when atomic oscillations stop; Coldest temperature reported on earth; Background on cryosurgery , the spinoff ...
“The day-night temp variations on the moon are so large that at least for half of the time, it would be too hot for the magnets to even operate,” Beacham says. Beacham notes the best bet is to bury the tunnel at least 100 meters underground, where it will still require some ...
