Which new method has been identified for predicting monsoon? |
| Answer» Lucrezia Terzi, a researcher at the Belgian Nuclear Research Centre (SCKCEN), has come up with a new way of predicting the monsoon at a science and technology conference organised in Vienna by the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO). The new method measures how much Beryllium-7 (an isotope of the element Beryllium) is present in the air. The Be-7 is chosen because it is created only in the stratosphere, when cosmic rays hit and break the nuclei of nitrogen and oxygen. Due to the sun warming the oceans differently at different latitudes, and the spin of the earth, water-bearing air moves up and down in circular fashions, which is the basic cause of the monsoons. When air flows down from the stratosphere (upwards of 33,000 feet from the earth's surface), it brings with it some Be-7. That makes the strong connection between the amount of Be-7 and the timing of monsoons. | |

The researchers from this organisation has discovered 28 new stars in Milky Way galaxy. |
| Answer» The Indian scientists at the Aryabhatta Research Institute of Observational Sciences (ARIES) have recently discovered 28 new variable stars in the Milky Way galaxy using 3.6 metre Devasthal Optical Telescope (DOT) established in 2016 near Nainital. The ARIES team of researchers was led by Dr. Sneh Lata and Dr. A K Pandey. It is for the first time that variable stars have been identified in Globular cluster NGC 4147 in the constellation of Coma Berenices. Besides the detection of new variable stars, the study also provides important insights into the internal structure of NGC 4147 which is located closer to the Earth than previously thought. A variable star is a star whose luminosity or brightness changes. This change may be caused due to periodical swelling and shrinking of the star or occasional block of light due to an eclipse by some other solar body. NGC 4147 was discovered by British astronomer William Herschel in 1784. | |
