South Atlantic Anomaly: NASA confirms dent in the Earth’s Magnetic field

The NASA Scientists have discovered a small but an evolving dent in the earth’s magnetic field. The dent has been found over South America and South Atlantic Ocean. It is an unusually weak spot and is called South Atlantic Anomaly. Highlights The Earth’s magnetic field acts as a protective shield to the planet as it Read More…

Magnetic Field of Solar Corona unveiled

The researchers in the University of Hawaii Institute for Astronomy have studied the interplanetary space of the sun called solar corona. Highlights The charged particles that are radiating from the surface of the sun is called solar wind. These particles expand and fill in entire solar system. The properties of solar corona are completely dependent Read More…

Sun has entered into deepest period of Sunshine Recession

The sun has reached into a state of ‘solar minimum’. It has been more than 100 days since sun has shown zero sunspots. The sun is to enter into the deepest period of ‘sunshine recession’. Highlights The cycle of the sun lasts for 11 years. This is called Solar Cycle. Solar minimum does not mean Read More…

New Code by Indian Scientists to study magnetosphere of the earth

The Indian Scientists at the Indian Institute of Geomagnetism has developed fluid simulation code to study electric field structure in the magnetosphere of the earth. Significance The study will help to plan the future space missions. The study will also lead to control fusion experiments to fulfill ever-expanding energy demands of humanity. Highlights The scientists Read More…

Indian Scientists Discover model to predict Ionospheric Electron Density

The Indian Institute of Geomagnetism researchers have developed a model that will predict electronic density of ionosphere. This is highly important for the communication and navigation on the earth. Highlights The researchers developed an Artificial Neural Networks based Global Ionospheric Model (ANNIM) to predict ionospheric electron density. The model was developed by using data collected Read More…
