Moment: Sun produces humongous 'light-bulb' solar storm


An enormous sun eruption, shaped like a giant glowing light bulb, was captured by a veteran spacecraft that closely monitors our nearest star. NASA scientists dubbed the sun storm a solar "Eureka! moment."The Solar and Heliospheric Observatory (SOHO) spacecraft, which is a joint mission by NASA and the European Space Agency, snapped the new photos of the bulbous, light bulb-shaped coronal mass ejection as it erupted from the sun's surface on Aug. 20.Coronal mass ejections (CMEs) are massive clouds of plasma and charged particles that are unleashed into space duringstrong solar storms. When powerful CMEs are aimed directly at Earth, they can cause geomagnetic and solar radiation storms, which have the potential to disrupt power grids and communications infrastructure on the ground.You can find a variety of lights available including the solar spot lights, solar ground lights and the Lighting Africa Offers. You can choose the one among them based on your needs. This is the best way to do your part on saving the environment and saving yourself big bucks. That is the reason that these are becoming increasingly popular among the people today and used at a variety of places. These solar eruptions can also knock out satellites in space.
Thin, wispy outer edge. It's not uncommon for CMEs to have a rounded shape, but according to NASA officials, it has been years since one took on the appearance of a light bulb.In the new image,Though there are many wholesale companies which offer you wholesale solar panels, but it is hard to find the best. You need to look out for superior quality when you are looking for buying China Solar Chargers Wholesalers like solar lanterns, solar lights, etc. It is always beneficial if you are looking for solar lights in bulk. the white circle at the center represents the solar disk, and the photo includes the inner solar corona region up to a staggering 5.25 million miles (8.4 million kilometers) away from the sun, NASA officials said.SOHO captured photos of the fun-shaped CME on Aug. 20, when a series of eruptions were unleashed from the sun. The spacecraft used its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument to make the observations.
This instrument is capable of snapping images of the outer layer of the sun, known as the corona, by blocking out the sun's light and creating an artificial eclipse within the instrument, NASA officials explained.SOHO was launched into space in December 1995, and uses 12 different science instruments to stare at the sun. The spacecraft is located roughly 930,000 miles (1.5 million kilometers) away, near a region called the Lagrange Point 1 between Earth and the sun, where gravitational forces combine to create a relatively stable environment.The cost approach would normally be used for new assets that someone has built himself or herself and for which there is no comparable sales data. It basically looks at the costs of building the project and adds a profit margin. The underlying assumption is that a buyer would pay no more for the property than the cost of producing another identical property.There are hundreds of options when it comes to motion sensing lights. Most hardware or home improvement stores carry these devices but China Motion Sensor Lights Wholesalers can also order them online where there may be a bigger selection of styles and varieties.You have many choices when it comes to outdoor motion sensing lights.
