top 5 science discoveries in 2019

1.Black hole

Real image of Black hole

The biggest discovery that take place in 2019 was the “First Image Of Black hole” .you all know that scientist are willing to know about the outer world(space) and one of the many interesting thing is Black hole . Scientist are very curious to know about black hole as it is hiding the most interesting facts about the space and our world. We all are read and understand about the black hole but we don’t know that the black hole does exist or not as we don’t have any photo of black hole until 2019. But on previous year (2019) scientists  took the photograph of black hole and confirmed the existence of it. The Photograph was took from 8 Radio Telescope which was also known as Event Horizon Telescope collaboration. They were fixed at different location on the earth which collectively collects the lights coming from Black hole and made a large data of about 50,00,000GB (5 million GB) and it took about 2 years by scientist to arrange this data perfectly than finally on 10^th April 2019 they got the image of black hole. About 200 scientists arranged this data to form a perfect image.

2.Arrokoth

Arrokoth

On 26 June 2014 an American astronomer Mare William and the New Horizons team seen a different object on Kuiper belt with his Hubble space telescope and named it 2014MU₆₉ . That thing was like a iceberg which is also known as commit but when another scientist Marc saw it then that thing was not looked like a commit asit is 36km long which is 10 times more than a normal commit and also 1000 times denser than a commit and it shape was also different like it was formed by attaching 2 commit with each other which is also known as binary commit system . One of them commit is 21km and other was 15km big and are attached to each other and were named as Ultima Thule and collectively is known as Arrokoth means “a distant unknown region ” . With the new horizon space probe’s (A NASAs space craft made by new horizon team) flyby on 1 January 2019 ,Arrokoth became the farthest and most primitive object in the solar system visited by spacecraft. At the time of New Horizons flyby , the object had been nicknamed Ultima Thule. Arrokoth was 1% bigger than the puto in size but its shape was like snowman .Therefore, scientist are studying about its structure and were finding the answer about its structure.

 

 

3.K2-18B

k2-18b

On September 2019 NASAs’ scientist founded a planet  and named it as K2-18B which is 124 light years (1.173 X10¹⁵km) far away from our earth planet it was founded by the Kepler space Telescope which was specifically designed by NASA to find planets which are like earth . The Kepler space telescope was lanuched on 7 march 2009 by NASA . The Kepler space telescope founded a planet which was named as K2-18B But that time scientist doesn’t have information that the planet was habitable or not. But on 2019 researches and scientist founded it to be habitable as it contain water bodies and also have the temperature between 0^o – 40^o which was habitable . Its size was also 8times of earth . On this planet two universities researched and founded that the formation of clouds also occur on it but scientist are not sure about  its  ground surface  that’s why scientist right now are not able to say that the planet is fully habitable or not. They are researching for its surface information .

4.CHANG’E-4

CHANG’E -4 was robotic spacecraft mission, part of the second phase of the Chinese Lunar(moon) Exploration Program. It was launched by China space center on 3 January 2019 .In this Mission China landed their rover in back to the farpart(L₂ point) of the moon . China became the first country to do so successfully .

5.Voyager – 2

voyager-2

Voyager – 2 was the one of the biggest achievements  as Voyager -2  on 2019 crosses the solar system which make it the first object made by the human  which go far from Uranus and Neptune and leaves back the solar system . Its speed was 57890 km/hr at the time of leaving the solar system.It was launched on 20 August 1977 by the NASA and today it left  the solar system and moving beyond the solar system  in the Space.
