How Often Do Solar Flares Occur? Smaller solar flares occur more often than large ones. The frequency of any flare occurring depends on the activity of the Sun. Following the 11-year solar cycle, there may be several flares per day during an active part of the cycle, compared with fewer ...
The Aurora Australis, like its northern cousin, is difficult to predict with precision. It has stops and starts (known as sub-storms). Patience is important, but so is information. Here are some tools that will increase your chances of seeing it. ...
The colors of the aurora change depending on which sun storm electrons and protons collide with which atoms and molecules in Earth’s atmosphere. The green light and the deep, broad red color that often occur high in Aurora appear when electrons collide with atomic oxygen atoms. The bluish-tin...
Auroras occur on other planets, too — all that's required to make an aurora is an atmosphere and a magnetic field. "Auroras have been seen in the atmospheres of all thegas giant planets, which is not surprising, since these planets all have robust magnetic fields," said Jeff Regester, ...
—Auroras over Earth: Amazing northern lights photos from space —What is the solar wind? Auroras occur on other planets, too — all that's required to make an aurora is an atmosphere and a magnetic field. "Auroras have been seen in the atmospheres of all thegas giant planets, which is...
However, the most intense and widespread auroras tend to occur when solar activity is at its greatest. Our active Sun The progression of Solar Cycle 24, from 2008 through 2019, is shown in this graph of sunspot count, revealing...
Can you see the northern lights from the Blue Lagoon? Yes, though it's less likely as the Blue Lagoon typically closes in the late evening during the winter and early spring, which is often too early to see the northern lights.
In the industrial world, X-ray scanners are often used to detect minute flaws in heavy metal equipment. And X-ray scanners have become standard equipment in airport security, of course. The X-Ray Machine The heart of an X-ray machine is an electrode pair -- a cathode and an anode -...
When this radiation and these particles reach the Earth's magnetic field, they interact with it at the poles to produce the auroras (borealis and australis). Solar flares can also disrupt communications, satellites, navigation systems and even power grids. The radiation and particles ionize the at...
Treating bacterial infections with antibiotics often kills intestinal flora, leading to diarrhoea and inflammation of the gut. Often it is bacteria known as Clostridium difficile which are responsible; they proliferate when the normal microbiome is kille
