what is aurora – pressnews

[ad_1] Auroras are one of the most visually stunning sky phenomena visible on Earth with naked eyes. The solar particles released during interaction of a solar storm with Earth's magnetic field further interact with the various gases present in our atmosphere and form stunning Auroras. However, auroras are not the only visually-pleasing sky phenomena. One other phenomenon takes place, but it is much rarer than auroras. It is known as Airglow.According to NASA, Airglow is a type of chemiluminescence from chemical interactions between oxygen, nitrogen, and other molecules in the upper atmosphere. It occurs in the form of dayglow and nightglow. Nightglow is more easily visible during the dark as airglow is just one billionth as bright as our Sun. NASA's Astronomy Picture of the Day is a s...

[ad_1] Over the last few days, the Earth has suffered the onslaught from a solar flare, a geomagnetic storm and a coronal mass ejection (CME). But what are they and how do they differ? NASA explains. The last few days have been pretty terrifying for the Earth. Our planet has been suffering from a solar storm onslaught that included two different X-class solar flare eruptions and a geomagnetic storm, all within just a week. This has resulted in radio blackouts in Australia, New Zealand and South America as well as the fascinating aurora displays in the arctic circles. But as we continue to report on the latest solar disturbances, what do these terms actually mean and how are they different from one another? If you've been confused about them as well, don't worry. NASA has come to your ...
