It releases winds that head towards the earth. A huge spot is discovered on the surface of the sun
A huge spot, 20 times the size of the Earth, penetrated the sun, releasing a solar wind that moves very quickly towards the planet.
What do we know about the new sunspot?
- The new sunspot or coronal hole is located on the sun's equator.
- It releases solar winds heading towards the planet.
- This solar wind has a speed of 1.8 million miles per hour.
- Our planet is expected to witness the impact of the winds on Friday, according to the British Daily Mail.
- Scientists are watching the situation closely, to see if the winds will affect the Earth's magnetic field, satellites and technology.
Coronal spots
- The two spots on the sun's surface were spotted by the NASA Solar Dynamics Observatory, which studies the sun.
- The first spot, spotted on March 23, was 30 times the size of Earth and spewed solar winds that caused spectacular aurorae as far south as Arizona.
- NASA explained that "sunspots are magnetically open regions, and they are one of the sources of the high-speed solar wind."
- The spots appear dark when viewed in many wavelengths of intense ultraviolet light. Sometimes, the solar wind can generate aurorae at higher latitudes on Earth.
- While the image of the spots may seem alarming at first, it does not indicate that planet Earth is in danger.
- Coronal spots are a common feature of the Sun, although they appear in different locations - particularly near the poles - and with greater frequency at different times in the Sun's activity cycle.
- They are cooler, less dense regions, and are generally more common when the Sun is at its least active point in an 11-year cycle.
Are these spots a danger to the Earth?
- Spots are usually harmless, but sometimes they can disrupt satellite communications and high-altitude radio transmissions.
- "The shape of this coronal spot is not particularly distinctive, but its location makes it very interesting," Daniel Verscharen, assistant professor of space physics and climate at University College London, told Insider.
- The scientist added, "I expect some fast winds from this coronal spot, to come to Earth from Friday night to Saturday morning this week."
