Astronomers unveil the magnetic field of the solar corona

While the world dealing with the corona virus pandemic researchers at the University of Hawaii Institute of Astronomy have been hard at work studying the solar corona, the outermost atmoshphere of the the Sun which expands into interplanetary space.

This stream of charged particles radiating from the surface of the sun is called the solar wind and expands to fill the entire solar system.

The properties of solar corona are a consequence of the sun complex magnetic field which is produced in the solar interior and extends outward.

The charged particles that are radiating from the surface of the sun is called solar wind. These particle expand and fill in entire solar system. the properties of solar corona are completely dependent on the magnetic field of the sun. The magnetic field is produced int the interior and extends outward.

Study

The solor corona can be easily seen during a solar eclipse . The magnetic field lines of solar corona were recorded for over 14 eclipses that occured in 2 decades.

Acc. to the observations, during the periods of minimum solar activity, the corona field came straight out of the usn near the equator and poles. During the maximum solar activity, the magnetic field was radial.

Amery Ice Shelf: Increase by 24% by 2021

                                    

The National Centre for Polar and Ocean Research has predicted that the Amery Ice Shelf is to expand 24% by 2021. The Ice Shelf would expand another 24% by 2026.

The NCPOR observations is based on 16 year-long satellite observations. The covered 60,000 sq km of the Amery Ice Shelf.

Amery Ice Shelf

Amery ice shelf is located in the east coast of Antarctica. It is one of the largest ice shelf in the world.

The mass balance and dynamics of the ice shelf help in understanding the changes in global climate scenario.

The Amery Ice shelf extended by about 550 Metres in 201, 1470 metres in 2018 and 2200 metres in 2019. if the extension of the ice shelf continues, the positions will coincide with actual boundary conditions.

NCPOR

Th National Centre for Polar and Ocean Research (NCPOR) is the indian institution that perform country's reserach activities in Polar and southern oceans.

It performs geoscientific surveys in the extended continental shelf, deep sea drilling in Arabian Sea basin and also explore the ocean for resources such as multi metal sulphides, Gas hydrates etc. The institute is located in Goa.

SWADES Initiative- Mapping Skill Programme for Indian Returing from Overseas

The Government of India is to conduct SWADES initiative to map the skills of Indians returning from abroad. SWADES is Skilled Workers Arrival Database for Employment Support.

The SWADES initiative has been begun under Vande Bharat Mission. The initative aims to generate database of indians returning from abroad based on their skill sets and experience.

SWADES Initiative

To Help fulfill the demand of Indian & Foreign Companies in India, Skill India Mission under the Initiative SWADES will create a database of skilled overseas citizens coming back to the country and map their skillsets to suitable jobs.

The initiative is to be conducted by Ministries of Civil Aviation, External Affairs, Skill Development and Entrepreneurship. The form consists of details of job tittle, work sector, years of experience etc. A toll free facility has also been set up to support citizens for their queries in filling the forms.

COVID-19 Pandemic

The COVID-19 pandemic led to the closing of companies all over the world. This made 1000s unemployed. Thus, they are returning to India.

Did You Know About Black Box ?

Black box is a device which records the cock pit voices and some other functions of the air craft like the engine speed and the altitude etc.  Black box is usually orange in colour not in black

The black box is a generic term for two recording devices carried aboard commercial airliners. it is very hard substance made of hardened steel and titanium. The Flight Data Recorder records a variety of parameters related to the operation and flight characteristics of the plane.

The Cockpit Voice Recorder recors the voices of the flight crew, engine noise and any other sounds in the cockpit. All large commercial airliners and certain varieties of smaller commercial, corporate, and private aircraft are required by law to carry one or both of these boxes, which generally cost between $10,000 and $15,000 a piece.

The data these devices provide is often invaluable to experts investigating the events leading up to an accident. The Recovery of the boxes is one of the highest priorities in any mishap investigation, second only to locationg survivors or recovering the remains of victims, and to indentify potential maintenance issues.
