temperatures in this layer can soar to as high as 4,500 degrees Fahrenheit. This intense heat is primarily due to the absorption of high-energy X-rays and ultraviolet (UV) radiation from the Sun. However, because the gas molecules
aChinese scientists and experts frame the space program partially in terms of the nation’s constant quest for energy and raw materials, talking about helium-3 and solar power as potential energy sources on the moon, as well as its reserves of titanium, rare earths, uranium and thorite 中国科...
The intrinsic features of the solar interior, e.g., the stratification, the turbulence and the nonlinearities, make the global MHD simulations of solar convection with the realistic parameters of the Sun extremely hard. The past substantial progress in understanding the solar magnetic cycle benefit...

And how much space does it take to hold 1.3 million Earths? And while we’re at it: How does the sun emit energy? Did the sun kick-start life on Earth (and the rest of our solar system)? Does the sun rotate? Why does the sun send out solar flares? Will the burn out? (And ...
Perspective: Having coffee in your kitchen one morning and you sense something is not quite right. The next instantyou are no more. Some asteroids are too fast to detect early. “On March 23, 1989 an asteroid passed within earths orbit only 400,000 km away. This asteroid is presumed to ...
(excluding fugitive methane) through operational efficiency, electrification, and renewable-energy use. Capital investments are required to achieve most of the decarbonization potential, but certain measures, such as the adoption of renewables, electrification, and operational effic...
There’s a new definition of insanity: trying to satisfy net-zero carbon dioxide gas emissions targets without nuclear power. Australia’s PM, Scott Morrison’s energy policy falls well within that definition, which probably makes this country one of the
