Over the past couple of years, many individuals with precarious understandings of science have said that a massive solar flare will swell up from the Sun in 2012, killing everyone on Earth and destroying the planet. That is, simply put, absolutely impossible, NASA researchers explain.
What is very important to know... |

For quite some time now, climate researchers have figured out that clouds play a critical role in determining the amount of sunlight that makes its way to Earth, and is retained here to warm the planet. A new study has just found that the amount of light that passes through depends on the photons' wavelength.Exp... |

NASA solar physicists say that the Sun exhibited another sign that it's heading for a solar maximum recently. On March 19, a massive eruption on its surface led to the release of a huge plasma tendril into its surroundings. This is the third time in just a couple of months a major solar event occurs. The phenome... |
