The brightness of the sun is decreasing, the age of snow is returning!

Banglahant Desk: Scientists are saying that the brightness of the sun has decreased by analyzing the data of NASA. According to them, the Sun is weaker than other stars like him in the galaxy. But why did the sun become so dim? Scientists are looking for the reason

The sun is the only source of energy on earth. But over the last 9000 years it has been steadily weakening. Its brightness is declining. This was claimed by astronauts at the Max Planck Institute in Germany. Scientists at the Max Planck Institute have published data from the US space agency NASA's Kepler Space Telescope. Scientists report that the Sun's brightness is fading compared to other stars in our Milky Way galaxy.

The Sun and other stars have been studied based on their age, brightness and rotation. In the last 9000 years, its brightness has decreased five times. Dr. Alexander Shapiro, a scientist at the Max Planck Institute, says that we are surprised that more active stars are present in our galaxy than in our Sun. We have come to this conclusion by comparing the Sun with 2500 stars like it.

Is the sun causing global warming? No. The sun can influence Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. The sun is a giver of life; it helps keep the planet warm enough for us to survive. We know subtle changes in the Earth’s orbit around the sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity. In fact, recently (2005-2010) the sun has become less active, while temperatures have marched upwards. One of the “smoking guns” that tells us the sun is not causing global warming comes from looking at the amount of the sun’s energy that hits the top of the atmosphere. Since 1978, scientists have been tracking this using sensors on satellites and what they tell us is that there has been no upward trend in the amount of the sun’s energy reaching Earth. A second smoking gun is that if the sun were responsible for global warming, we would expect to see warming throughout all layers of the atmosphere, from the surface all the way up to the upper atmosphere (stratosphere). But what we actually see is warming at the surface and cooling in the stratosphere. This is consistent with the warming being caused by a build-up of heat-trapping gases near the surface of the Earth, and not by the sun getting “hotter.” Video: The sun as seen from NASA & # 039; s STEREO-B mission.

Another scientist, Dr. Timo Reinhold, who made this report on the sun, said that the sun had been quiet for thousands of years. However, the number of solar flares has also decreased in the last few years. Since 1610, the solar spots formed on the sun have been steadily declining. Last year, not a single spot was seen for about 264 days. Solar spots are formed when strong heat waves rise from the center of the sun. It caused a big explosion. As a result, a solar storm arose in space.

Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA. Every year, the cap of frozen seawater floating on top of the Arctic Ocean and its neighboring seas melts during the spring and summer and grows back in the fall and winter months, reaching its maximum annually extent between February and April. On March 24, Arctic sea ice extent peaked at 5.607 million square miles (14.52 million square kilometers), a new record low winter maximum extent in the satellite record that started in 1979. It is slightly smaller than the previous record low maximum extent of 5.612 million square miles (14.54 million square kilometers) that occurred last year. The 13 smallest maximum extents on the satellite record have happened in the last 13 years.

The Sun is believed to be 4.6 billion years old. 9000 years is nothing compared to that. The Max Planck Institute also included the University of New South Wales in Australia and the South Korean School of Space Research in the study. Dr. Sami Solanki, who was involved in this study, said that the rotation of the axis of any star shows the strength of its magnetic field. When the magnetic field is strong, the action of the center and surface of the star is correct. It shows how much sun is moving.

Dr. Solanki said that if the sunlight continues to decrease. There was no explosion of fire. Solar spots are not being created. This means that the Sun is definitely weaker than other stars. Its brightness has decreased.
