Solar system is named because of Sun, it’s main part. It is present in the centre of solar system around which planets revolve. It is the star closest to earth. It is a hot ball of hydrogen and helium having 15 million degree celsius temperature in its core.
The sun formed more than 4.5 billion years ago, when a cloud of dust and gas called a nebula collapsed under its own gravity. Sun is 26,000 light years from milky way’s galaxy. Many satellites work on the study of sun’s surface. Here are some detailed information related to sun. What are they, let’s see.
Recently, a mysterious object is found in the solar cell, named Hedgehog.
ESA- Solar orbiter
The European Space Agency’s Solar Orbiter is a satellite that observes the sun, the solar wind, and the solar polar, to unravel the mysteries of the solar system. On the 26th of March this year, the Sun is very close to it. An analysis of the information sent by it revealed a remarkable vision of powerful flares in all solar panels. NASA and the UK Space Agency also contributed to the project.
When it got very close to the Sun, the satellite was inside the orbit of Mercury, the nearest planet to the star. At this point, the heat shield of this space engine saw a rise in temperature of more than 500 degrees Celsius. Fortunately, human ingenuity has kept 10 scientific instruments as cool as possible.
Through its technician, the orbiter, is constantly trying to provide an unprecedented insight into how our local star ‘works’. According to ESA, the closer the spacecraft is to the Sun, the more details are detected by a distant sensory device. During this time, the satellite was able to capture solar flares and even Earth-directed coronal mass ejection.
A mysterious object was discovered in a solar cell, and a scientist has dubbed it the ‘hedgehog.’ He photographed the Extreme Ultraviolet Imager (EUI), taking photographs showing the high resolution of the solar corona, the lower layers of the Sun. the atmosphere. It is not even known how these hedgehogs formed in the Sun’d atmosphere.
David Berghmans, Principal Investigator (PI) of the EUI, however, called the images ‘breathable’ and said the object would keep them busy for years as it traveled 25,000 kilometers across the Sun and contained large amounts of hot and cold gases. reaching out to all sides.It shows spikes of hot and cold gases – about a million degrees Celsius – pointing in different directions.
At 25,000km the crossing is the smallest aspect of the Sun – extending the distance twice the Earth’s circumference.Scientists will look at past data on the Sun to see if they can find previous examples of hedgehog going under radar.Solar Orbiter also absorbed a large number of solar flares during its operation.
Finding out more about these events can help in predicting the future weather. Understanding the high frequency emissions is important because of the growing threat of such events in technology and space.
Caroline Harper, head of space science at the UK Space Agency, said: “It’s very exciting to see these beautiful images and photographs; the closest we have ever seen of the Sun, taken during the recent passing of the Solar Orbiter so far. This event, in turn, appears to double the Earth’s surface and encompass a small fraction of the sun’s mass of 1.4 million miles [1.4 million km].
This 11-year solar cycle and the activities that regulate these periods, including solar flares, sunspots, and CMEs, can be understood by learning more about solar panels, experts say.
So, sun is too unveiling many different things. These are going to help in studies and researches. You will find many more unveiling topics here. Check out other article as well to know more.
