    Sun
    1/5 The Sun is the largest object in our solar system and is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of the solar system. It is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet. (Pixabay)

    2/5 The Sun’s volume would need 1.3 million Earths to fill it. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it. The hottest part of the Sun is its core, where temperatures top 27 million degrees Fahrenheit (15 million degrees Celsius). The Sun’s activity, from its powerful eruptions to the steady stream of charged particles it sends out, influences the nature of space throughout the solar system. (NASA)

    3/5 According to NASA, measuring a “day” on the Sun is complicated because of the way it rotates. It doesn't spin as a single, solid ball. This is because the Sun’s surface isn't solid like Earth's. Instead, the Sun is made of super-hot, electrically charged gas called plasma. This plasma rotates at different speeds on different parts of the Sun. At its equator, the Sun completes one rotation in 25 Earth days. At its poles, the Sun rotates once on its axis every 36 Earth days. (NASA)

    4/5 Above the Sun’s surface are its thin chromosphere and the huge corona (crown). This is where we see features such as solar prominences, flares, and coronal mass ejections. The latter two are giant explosions of energy and particles that can reach Earth. (Pixabay)

    5/5 The Sun doesn’t have moons, but eight planets orbit it, at least five dwarf planets, tens of thousands of asteroids, and perhaps three trillion comets and icy bodies. Also, several spacecraft are currently investigating the Sun including Parker Solar Probe, STEREO, Solar Orbiter, SOHO, Solar Dynamics Observatory, Hinode, IRIS, and Wind. (Pixabay)

    Know all about the solar storm that is set to hit the Earth later this week. (NASA)

    The Earth is constantly battling the radiation and the attacks on its magnetic field coming from the Sun, but lately it has turned from bad to quite worse. After escaping from a potential G5-class solar storm event from an unstable sunspot recently, now another danger is coming for the Earth. A hole has emerged on the southern hemisphere of the Sun, which is releasing a high-energy stream of plasma. This stream of plasma, also known as fast-moving solar winds, are expected to hit the Earth later this week and cause a powerful solar storm. Read on to know the consequences of this solar disturbance.

    The development was reported by SpaceWeather.com which noted on its website, “A fast-moving stream of solar wind is expected to hit Earth's magnetic field on Nov. 19th or 20th. It is flowing from a southern hole in the sun's atmosphere. High-latitude sky watchers should be alert for auroras at the end of this week”.

    Dangerous solar storm brewing for the weekend

    While the website only spoke about auroras, the incoming solar storm is capable of much worse. While it is not possible to gauge how powerful the incoming solar storm can be, it is likely that it will not be a very intense storm. However, it is still capable of causing disruption in radio waves and cause a radio blackout. This can also impact GPS systems. As a result, flight timings can be delayed and ship transportation can be affected. If you are in the affected zone (which you can find out closer to the weekend on the National Oceanic and Atmospheric Administration website), you should check if any of your flights have been rescheduled.

    While this solar storm may not be a strong one, the threat of a G5-class solar storm has not entirely gone. The Sun is still reaching the peak of its solar cycle and the intensity and frequency of solar storms are only about to get much worse. In case you're wondering how it may impact you, you should know that such solar disturbances can damage satellites, impact mobile networks and internet connectivity as well as cause power grid failure. Although humans will not be directly impacted by the radiation, due to disruptions to emergency services and power outages at places of high importance, it can still cause a high number of deaths.
