    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)

    The Earth has become a standing target for the incessant solar storm attacks this year. And after a small break, the solar storm attack is back again. According to the National Oceanic and Atmospheric Administration (NOAA), fast-moving solar winds are going to strike the Earth tomorrow, September 23, causing a solar storm. This event takes place mere days after a solar flare eruption on the Sun caused radio blackouts in Africa and the Middle East. But how powerful is this solar storm and should we be concerned? Read on to find out.

    This development was reported by SpaceWeather.com which noted on its website, “NOAA forecasters say that a minor G1-class geomagnetic storm is possible on Sept. 23rd when a high-speed stream of solar wind is expected to hit Earth's magnetic field. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. High-latitude auroras are possible when the windy stream arrives”.

    Solar storm to hit the Earth tomorrow

    Right now, it is not possible to fully gauge just how this solar storm might affect us. On top of that, due to it being on the day of equinox, the magnetosphere of Earth will be weakened, resulting in easier access of solar particles and radiation to enter the Earth's atmosphere. This can also increase the intensity of the storm and can cause radio blackouts and GPS disruptions that may lead to travel delays.

    With the Sun moving towards its solar maximum, the main threat Earth is facing is being struck by a G5-class solar storm. Such a solar storm can burn and destroy satellites in Earth's lower orbital space and massively disrupt and breakdown wireless communications like shortwave radio transmissions, GPS, mobile network and even internet access. In the worst case scenario, power grids can also be damaged due to such a solar storm.

    How NOAA tracks these solar storms

    All of this information is being collected in real time through some amazing tech. NOAA monitors the solar storms and Sun's behavior using its DSCOVR satellite which became operational in 2016. The recovered data is then run through the computers at the Space Weather Prediction Center and the final analysis is prepared. The different measurements are done on temperature, speed, density, degree of orientation and frequency of the solar particles.
