Scientists say that Pluto Should be Considered a Planet

For the association a star is considered a planet when it orbits around a star has a spherical shape and manages to be gravitationally dominant It is precisely in this last aspect that the IAU believes that Pluto will fail

According to Fox 13 News the authors of the article urge the association to use a more complex and pervasive criteria across science to carry out the classification of planets

A planet is an condensate where physics produces complexity in geology mineralogy chemistry and possibly atmospheres oceans magnetospheres biology and more making this planet concept not an arbitrary definition but one of the most common alignments important with explanatory vision in all of science

The articles authors also point out that the definition used by the IAU is constantly questioned by the world community of astronomers The researchers call for a concept fundamentally geophysicalgeological not limited by the current orbital status of a body

In a note sent to Fox channels the IAU said that it respects all scientific advice and welcomes open debate The scientific decisionmaking authority of the IAU is the general assembly which takes place every three years Proposed resolutions must be submitted to the Resolutions Committee

Also according to the IAU any request to review concepts is welcome even if the results of this study have not been analyzed by other scientists

Because it is beyond the Moons orbit and far from the region in which current manned space shuttles can reach inperson maintenance on the James Webb should not be done

It is estimated that the telescope has a useful life of about ten years James Webb Space Telescope will be launched by NASA this Saturday 25 in a project that spanned three decades between conception construction and sending to outer space In partnership with the European Space Agency ESA in English and the Canadian Space Agency ASC in English

The equipment will replace the famous Hubble telescope launched in 1990 James Webb has a set of primary mirrors 65 meters in diameter according to NASA The structure is composed of 18 goldplated hexagonal mirrors coupled to the remaining segments of the telescope The James Webb weighs 65 tons and has an electrical power of 2000 watts

On January 20 2017 James Webbs mirrors were placed in a chamber that simulates outer space specifications such as temperature The structure came to face 236°C and passed the tests carried out by NASA engineers

The powerful mirrors of the James Webb rated by NASA as the most powerful telescope ever created by man will observe the evolution of galaxies as well as the formation of the first galaxies and stars The equipment will capture infrared light and turn it into information for NASA scientists

To protect the telescopes entire vital system NASA designed five plates of a special material the dimensions of a tennis court Equipment such as the solar panels to power the James Webb were placed below these structures

Built in California USA the James Webb was shipped by sea to French Guiana the launch site To reach the country the telescope even had to cross the Panama Canal an artificial channel that connects the Pacific and Atlantic oceans

The James Webb telescope will only reach final orbit in March according to NASA estimates The equipment will be more than 15 million km from Earth at a point in space called Lagrange L2 Point

Because it is beyond the Moons orbit and far from the region in which current manned space shuttles can reach inperson maintenance on the James Webb should not be done It is estimated that the telescope has a useful life of about ten years

The James Webb Space Telescope will be launched by NASA this Saturday 25 in a project that spanned three decades between conception construction and sending to outer space In partnership with the European Space Agency ESA in English and the Canadian Space Agency ASC in English the equipment will replace the famous Hubble telescope launched in 1990.
