  • The science communities since a long time have been debating upon the existence of Planet Nine. 
  • Space highlights different shreds of evidence based on which scientists are stating the claim.

What Is Planet Nine?

Planet Nine is a hypothetical planet present in the far outer Solar System, whose mass is estimated to be 10 times more than the mass of Earth. The planet is said to be 20 times farther than the sun than Neptune is.

What Do Researchers Have To Say?

Dr Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology, said that there were five different lines of observational evidence which pointed to the existence of Planet Nine. He stated that if this theory does not sound believable, then people would have to come up with the answers of the five pieces of evidence which could lead to further confusion.

Batygin in 2016 published a study examining the six known objects in the Kuiper Belt, a  circumstellar disc in the Solar System beyond the planets that extends from the orbit of Neptune towards interstellar space.

The study examines all the objects have elliptical orbits pointing in the same direction and are tilted the same way. These serve as evidence to the planet’s existence.

It is being said that the objects are tilted 30 degrees downward compared to the plane where the eight official planets circle the sun. Researchers also made use of computer simulations of the solar system including the Planet Nine and to demonstrate that there should be more objects tilted a whopping 90 degrees to solar plane. It was revealed that five such objects, which fit these parameters were already known.

The study led to the birth of two more ideas. Researchers said that this planet could have tilted the planets of the solar system during the last 4.5 billion years.

Planet Nine’s existence could also tell the reason as to why Kuiper Belt objects orbit in the opposite direction as compared to other things in the solar system.

Number of Students Opting for Science or Tech Are On Rise in India

India leads the world in the number of students getting bachelors degrees in science, technology, engineering and maths (STEM) subjects, according to the UN Conference on Trade and Development (UNCTAD).

India leads the world in the number of students getting bachelors degrees in science, technology, engineering and maths (STEM) subjects, according to the UN Conference on Trade and Development (UNCTAD).

Of about 5 million students who received their bachelor’s degrees in 2012 in STEM subjects worldwide, 29.2 per cent were from India, UNCTAD’s Technology and Innovation Report 2018 released on Tuesday said.

China came next with 26 per cent of the STEM graduates. The EU accounted for 9.5 per cent of STEM graduates that year and the US for 6 per cent, the report said.

The report used statistics from 2012 and said the total number of bachelors-equivalent degrees awarded that year was 20 million.

The wide gulf in the numbers of students graduating in STEM explains why the US relies on such a large number of foreigners, especially Indians, to fill its technology workforce needs.

“Many countries are witnessing skills shortages in the fields of digital technologies and many employers report difficulties in filling high-skill vacancies,” UNCTAD said, citing a 2016 worldwide survey by ManpowerGroup on talent shortage that found that 40 per cent of employers reported difficulties in filling positions.

So, if your child is preparing for IIT-JEE or NEET from any of the reputed centres like Aakash Institute, as a parent, it's your responsibility to help your child find the right study time

According to India’s University Grants Commission, 10.7 million students were studying science, engineering/technology or computer science in 2016-17, although it did not give a breakdown between undergraduate and postgraduate levels or by year of study.

They made up 36 per cent of those studying in universities and colleges, UGC statistics showed.

Looking to the future, UNCTAD cautioned that “there were indications that educational institutions were not keeping pace with technological advances during the current transition period”.

It urged educational institutions to “react with agility” to the rapid pace of technology and the labour market changes and said this may require “significant transformations” in the education and training systems.

With the widespread use of artificial intelligence and robots looming on the horizon, the report said that “rapid technological progress required the labour force to develop a broader range of skills, focusing on humans’ comparative advantage, to increase employability”.

UNCTAD called for broadbasing education and said: “In the new technological landscape, there is a need for generic, core or fundamental skills such as literacy, numeracy and academic skills, together with basic financial and entrepreneurial skills and increasingly, basic digital and even coding skills.” (IANS)
