New Delhi, March 30: The Sun, located approximately 93 million miles (150 million kilometers) from Earth, significantly influences our daily lives. The phenomena resulting from solar activity are referred to as ‘space weather.’
In its most severe form, space weather can damage satellites and disrupt electrical systems on Earth. Studying space weather is crucial as life on Earth heavily relies on satellites, communication, and power systems. Scientists continuously monitor solar activity to prepare for potential threats.
So, what exactly is space weather? The Sun constantly emits streams of gas and charged particles into space, known as ‘solar wind.’ These particles originate from the Sun’s outer atmosphere, called the ‘corona,’ and travel towards Earth at speeds of nearly one million miles per hour.
Fortunately, Earth is protected by a strong magnetic field that acts as a shield. This magnetic field, along with the atmosphere, blocks most of the solar wind particles. When these particles collide with the magnetic field, they flow around the Earth. The side of the magnetic field facing the Sun flattens, while the opposite side extends like a long tail.
However, sometimes these charged particles penetrate Earth’s magnetic field and enter the atmosphere. When they collide with atmospheric particles, they create colorful lights known as ‘auroras.’ This stunning display can be seen in the northern and southern polar regions.
Occasionally, intense magnetic activity on the Sun leads to powerful ‘solar storms.’ During these storms, solar wind becomes much faster and more dangerous. They can occur suddenly and reach Earth within minutes. The effects can disrupt satellite operations, impact GPS systems, and even cause power outages.
Scientists keep a close watch on these phenomena. They attempt to predict solar storms in advance. NASA’s Solar and Heliospheric Observatory monitors coronal mass ejections, while the Solar Dynamics Observatory and NOAA satellite series continuously observe the Sun. These satellites issue early warnings about solar storms, helping to mitigate potential damage.
