These speeds are so high that the particles can escape the Sun's gravity. The next issue of The Toronto Sun Headline News will soon be in your inbox. Most affected are older people and those with health conditions. You can subscribe to our print edition, ad-free app or electronic newspaper replica here. Thailand has reported five cases; Australia has reported four; Singapore, France, Japan, Taiwan and Malaysia three; Vietnam, South Korea and the U.S. two each; and Nepal one. The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. Facts about the Sun. Thank you for supporting our journalism. There is some evidence to suggest the spread of the virus may slow down as the weather gets warmer. Omissions? Fact check: What's true and what's false about coronavirus? In... Total solar eclipse. Older people are more at risk for catching COVID-19.) Check symptoms. Only levels of UV light much higher than what is in sunlight can kill viruses, experts said, and the levels that kill viruses can cause irritation to human skin and should be avoided. NOW 50% OFF! Temperatures at the photosphere are around 5,500C (10,000F), the corona can reach temperatures of almost 2 million C (3.6 million F). Not just yet, LILLEY: Canada's first case of deadly coronavirus lands in Toronto, Canada’s first “presumptive positive case” of coronavirus has been confirmed in Toronto, tap here to see other videos from our team. This article was most recently revised and updated by, https://www.britannica.com/science/corona-Sun, Montana State University Solar Physics - Corona. What experts say: The sun’s UV light cannot kill the coronavirus, and concentrated UV light should not be used to kill the virus. However, the corona is very dim. Sign up to receive daily headline news from the Toronto SUN, a division of Postmedia Network Inc. Thatâs why experts are working so hard to figure out how to prevent people from getting the diseaseâand how to help them recover if they catch it. The corona's temperature causes its particles to move at very high speeds. The free electrons in the corona move along magnetic field lines and form many different structures including helmet streamers which can be seen as long, spiked cones in solar eclipse images. The shape of the corona is mostly determined by the magnetic field of the Sun. Find tips on how to safely view an eclipse here. Yet the corona is hundreds of times hotter than the Sun’s surface. The Sun is a main-sequence G2V star (or Yellow Dwarf). COVID-19 is a "novel coronavirus," which means it’s a new disease unfamiliar to scientists and doctors. The corona continually varies in size and shape as it is affected by the Sun’s magnetic field. The coronavirus was first reported in a city called Wuhan in the Huabei district of China on December 31. Itâs also good to stay away from large crowds of people where you canât be sure who might be infected. However, the corona can be seen during a total solar eclipse. … Get information. Its name is actually a mash-up of the words "corona" (CO); corona means "crown" in Latin (coronaviruses are named for the crown-like spikes on their surface), "virus" (VI), and "disease" (D). Unauthorized distribution, transmission or republication strictly prohibited. Friedman referred to sunlight as “virus destroying sunlight.” This is FALSE. This low density makes the corona much less bright than the surface of the Sun. Conceptual animation (not to scale) showing the Sun's corona and solar wind. If you don't see it please check your junk folder. The Sun is 109 times wider than the Earth and 330,000 times as massive. © 1996-2015 National Geographic Society, © 2015- Learn more about protecting yourself from the coronavirus and COVID-19. Cows, bats, and camels are among the animals that have spread diseases to humans in the past. You could also pick it up by touching doorknobs or countertops that an infected person has touched, and then touching your eyes, nose, or mouth. The corona reaches extremely high temperatures. Remember to never look directly at the Sun, even during an eclipse. The cards, which some people have purchased online, may have official-looking logos or government insignias on them. But astronomers think that this is only one of many ways in which the corona is heated. The SARS-like pathogen has killed 213 people and infected 10,000 in China itself. The term "coronavirus" actually refers to a family of viruses that causes many different types of diseases, including the common cold. The article listed UV light as one of seven “things that COVID-19 is afraid of.” AFP Fact Check reported the article was shared in a Thai-language health group on Facebook with more than 6,000 followers and posted on social media multiple times, translated into English and Spanish. That may lead some to incorrectly suggest sunlight as a tip to stay healthy. These include streamers, loops, and plumes. Fake cards and flyers, claiming that the bearer is exempt from mask-wearing regulations, have shown up in some areas. Most likely, it will be in the light bulb or lamp as the natural UV from the sun is not strong enough to kill it. Time magazine reported on new research that has not yet been peer-reviewed that suggested the possibility of a connection between heat and the rate of the spread of the coronavirus, but experts concluded the research is still early and not definitive. Our Sun is surrounded by a jacket of gases called an atmosphere. WHAT’S NEXT: The World Health Organisation (WHO) said the outbreak is an emergency for China but is so far not a global health emergency. CAUSE: It’s believed the virus came from illegally traded wildlife at an animal market in Wuhan, particularly the kait snake and Chinese cobra. The solar wind, which The surface of the Sun is covered in magnetic fields. Here is a list of myths and facts about the deadly virus: We answer the often searched question: "What are the symptoms of coronavirus versus the flu? HOW IT SPREADS: Researchers believe each person infected passes the disease on to two and three others. Coronal holes are sources of high-velocity streams in the solar wind. Viruses can change over time. The corona continually varies in size and shape as it is affected by the Sun’s magnetic field. A NASA mission called IRIS may have provided one possible answer. In 1940 the source of the lines was identified as weak magnetic dipole transitions in various highly ionized atoms such as iron…, …of stars are surrounded by coronas having temperatures of one million kelvins (K) or more. The corona can also be studied under noneclipse conditions with a special telescopic instrument called a coronagraph. In the video, Murphy, a physician who worked in urology and renal transplantation, stands in scrubs in front of a large white board and shares tips to prevent the spread of the coronavirus. Most people who catch COVID-19 get better, and their illness is usually mild. The claim holds little truth. USA TODAY reached out to Friedman and Murphy for comment but did not receive a response from either. The corona extends far out into space. On Saturday, Ontario government and health officials revealed Canada’s first “presumptive positive case” of coronavirus has been confirmed in Toronto — a man in his 50s who is being treated at Sunnybrook hospital. Disinfectants, bleach and soap and water may be used to clean surfaces, an important prevention step in stopping the spread of coronavirus and COVID-19 — the disease caused by the coronavirus that’s led to the global pandemic. It has a temperature of approximately two million kelvins and an extremely low density. But just like when youâve had a cold, the best treatment is to stay in bedâand away from anyone who might catch it from you. The reason it has spread so quickly from country to country is because of how much humans travel now. Dozens of drugs are already being tested around the world, and scientists are hoping to come up with a vaccine as soon as possible to prevent COVID-19 from spreading at this rate again.

But what do kids need to know about this disease?
