The scientists determined this because the speed of some of the observed particles is up to 10 times greater than the average for the solar wind - something only possible with a powerful phenomenon like magnetic reconnection. It is this process, called magnetic reconnection, that is responsible for flinging out the charged particles that we see as solar wind. The team thinks that when magnetic fields with opposite directions pass each other in these funnels, magnetic field lines break and then reconnect. That knowledge, and these new results, could aid the prediction of potentially disruptive solar storms, study team members said. But when the sun becomes more active and its magnetic field "flips," switching poles, coronal holes become more widespread, and these powerful streams of charged particles can be directed at our planet. ![]() This means that the solar wind that emerges from coronal holes isn't usually directed toward Earth. This causes open field lines that spread to fill the space around the sun.ĭuring quiet periods of our star's 11-year activity cycle, coronal holes are usually found at the poles of the sun. This discovery pointed to these regions as the source of the "fast" solar wind, which is seen over the poles of the sun and can reach speeds as great as 1.7 million mph (2.7 million kph), around 1,000 times faster than the top speed of a jet fighter.Ĭoronal holes are believed to form in areas where magnetic field lines emerge from the sun's surface but do not loop back there. The spacecraft saw that the streams of high-energy particles that make up the solar wind match so-called "supergranulation flows" within coronal holes.

NASA's sun-touching Parker Solar probe has flown close enough to our star to spot the fine details of the solar wind - including its origin, "coronal holes" in the sun's atmosphere.Īrmed with this information, scientists may now be able to better predict solar storms that can supercharge auroras over our planet but can also disrupt communication and power infrastructure and pose a threat to satellites, spacecraft and even astronauts. And despite the beer mile, beer during a bout of exercise isn’t a good idea, either.īut for those who love a cold beer after a hot, sweaty workout, go ahead and enjoy, just be sure to make healthy choices.Artist's illustration of nasa's parker solar probe observing the orange, highly active sun at close range. And while exercise expends energy, you might not always work out enough to burn off all the added calories that come from a night spent enjoying a few cold ones.įinally, given the neurological effects of alcohol (balance, coordination and spatial awareness are all negatively affected), no studies suggest having a pint or two before a workout or game is advantageous. Guidelines related to alcohol consumption state more than two drinks per week (341 ml/12 ounces of 5% alcohol beer) increase the risk of several types of cancer, including breast and colon cancer.

Keeping in mind not all beer recipes are alike and that most of the immunity boosting benefits of beer are found in barley malt (about 80 per cent) and hops (20 per cent), the type of beer you choose can impact the quantity of healthy ingredients. Other nutrients found in your favourite pint glass are carbohydrates, amino acids, minerals and vitamins. The natural plant-based compounds have anti-oxidizing properties that boost immunity and reduce inflammation. Made from water, barley, malt, hops and yeast, the healthy properties of beer are associated with their polyphenol content. Stronger bones, a reduction in cardiovascular risk and added anti-inflammatory and immunological benefits have all been linked to beer consumption. Consumed in moderation, beer is good for you. One of the oldest and most widely consumed beverages in the world, beer and sports go hand in hand, with many a win celebrated and loss commiserated over a frothy pint or two.
