Data from Parker Solar Probe helps unravel sun’s mysteries

Data from Parker Solar Probe helps unravel sun’s mysteries

Science
Dec. 4 (UPI) -- Over the last year, NASA's Parker Solar Probe flew closer to the sun than any previous spacecraft. Now, scientists are beginning to make sense of the measurements captured by the probe's four instruments during its first three record-setting flybys. On Wednesday, researchers published four new scientific papers, all supported by Parker Solar Probe data, in the journal Nature. According to the authors of the new studies, the observations and measurements recorded by the Parker Solar Probe are bringing scientists closer to solving some of the sun's greatest mysteries -- like explaining why the corona is a couple million degrees hotter than the sun's surface, where solar flares come from and what propels solar wind. "Some of the data confirmed what we already thought, but so...

Voyagers shed light on Solar System’s structure

Science
Data sent back by the two Voyager spacecraft have shed new light on the structure of the Solar System.Forty-two years after they were launched, the spacecraft are still going strong and exploring the outer reaches of our cosmic neighbourhood.By analysing data sent back by the probes, scientists have worked out the shape of the vast magnetic bubble that surrounds the Sun.The two spacecraft are now more than 10 billion miles from Earth.Researchers detail their findings in six separate studies published in the journal Nature Astronomy."We had no good quantitative idea how big this bubble is that the Sun creates around itself with its solar wind - ionised plasma that's speeding away from the Sun radially in all directions," said Ed S...

Tesla and Walmart address solar panel fire issues

Technology
US supermarket chain Walmart and Tesla are working to solve the issues which allegedly caused solar panel fires in seven of its stores, Reuters reports.It follows a lawsuit launched by the retailer, alleging "widespread negligence" when the panels were installed on roofs.Clean energy firm SolarCity had installed panels on 240 Walmart stores, and was bought by Tesla in 2016.In a joint statement, the firms said they were addressing the concerns.Every system needed to operate safely, they added.The firms said they were looking to "re-energise Tesla solar installations at Walmart stores, once all parties are certain that all concerns have been addressed"."Above all else, both companies want each and every system to operate reliably, ...

Total solar eclipse to cast a shadow on South America on Tuesday

Science
July 2 (UPI) -- For a few hours on Tuesday, across a small portion of the Southern Hemisphere, the sun will disappear behind the moon. During the total solar eclipse, the moon's shadow will darken parts of the South Pacific, Chile and Argentina. For those who don't live in or can't make it to South America, there will be several online streams of the event. Exploratorium, a San Francisco museum, will offer live telescope views of the eclipse from Chile beginning at 3:00 p.m. ET on its website. The European Southern Observatory's La Silla Observatory in Chile's Atacama Desert will also offer live coverage of the eclipse. At each location, the total solar eclipse will last just under two minutes. Solar eclipses occur when the moon passes in front of the sun. Of course, the moon regularly ...
