Biggest solar flare 2013 results in fast-moving solar storm to earth
Global Warming Means Oceans are Taking the Heat
The sun has been increasingly vibrant these days. It has been causing rage impact to the life on the earth in different ways. On Thursday (April 11), the sun has emitted a massive solar flare that is measured as the largest one this year so far.
The solar storm is now heading to the earth fast, but is not fierce enough to directly cause harm to humans and other earthly creatures. The flare is rated as M6.5 class, meaning that it is not as much strong as the largest solar flares of last year.
The recent solar flare resulted when a huge and Earth-facing group of sunspots flung towards the earth at high speed. NASA’s monitoring satellite namely the Solar Dynamics Observatory first spotted the Coronal Mass Ejection (CME), April 13th. Indeed, sky watchers should be able to watch colorful auroras in the sky owing to these geomagnetic storms.
“The high influx of charged particles buffeting the magnetic field can potentially pose a hazard to everything from GPS signals, polar radio communications, power grids”
particularly strong solar storms can knock power grids offline,” says US News.
USA Today reported it:
“A recent study found that heat absorbed by the world's oceans has increased significantly over the same period, prompting the study co-authors to say that the warming has been diverted and is heating the oceans instead of the atmosphere. The study was published in the journal Geophysical Research Letters, a publication of the American Geophysical Union.”
NASA funded study shows rain from Saturn’s Rings falls across the Planet:

In the early 1980s, images from NASA’s Voyager spacecraft showed two to three dark bands on Saturn, and scientists theorized that water could have been showering down into those bands from the rings. Those bands were not seen again until this team observed the planet in near-infrared wavelengths with the W.M Keck Observatory on Mauna Kea, in Hawaii, in April 2011. The effect was difficult to discern because it involves looking for a subtle emission from bright parts of Saturn. It required an instrument like that on Keck, which can split up a large range of light.
“Where Jupiter is glowing evenly across its equatorial regions, Saturn has dark bands where the water is falling in, darkening the ionosphere,” said Tom Stallard
These shadows cover some 30 to 43 percent of the planet’s upper atmosphere surface from around 25 to 55 degrees latitude.
