NASA’s Kepler and Spitzer space telescopes discover a Giant Storm on a Tiny Star

If you think windy storms are always linked to planets, then you must check new observation by NASA’s Kepler and Spitzer space telescopes. The lenses have spotted a giant storm on a distant dwarf star, according to a study published in the Astrophysical Journal.

The cool dwarf star, W1906+40, belongs to a category of L-dwarf. Some dwarf stars are also known as ‘failed stars’ because there is no nuclear fusion going on in their cores. But some stars like W1906+40 are capable of stroking their inner furnaces.

The star has some serious weather issues, scientists said. The star, about the size of giant planet Jupiter, has surface temperature approximately 3,500 degrees Fahrenheit, which means some fusion is still going on the stellar body. But it is not enough to form mineral clouds in the star’s atmosphere.

NASA’s Wide-field Infrared Survey Explorer first spotted the star about four years ago. That time, John Gizis from the University of Delaware, Newark and other scientists used Kepler data to know more about the distant stellar body. They looked at the star’s atmosphere and found that there was a huge storm closer to the north pole of the star. The storm was so huge that it was completing a trip around the star’s surface in just nine hours.

The researchers compared the storm spot with some other similar stars. They realized that a number of brown dwarf stars had rapid cloud evolution. “The long life of the cloud is in contrast with weather changes seen in cooler brown dwarfs on the timescale of hours and days”, they explained.

The researchers also said that the storm may have been going strong for at least two years.
