Chinese 'SUN' is three times hotter than our Sun

Chinese nuclear fusion scientists achieve temperatures three times hotter than the sun
The temperatures were roughly equal to a 'mid-sized thermo-nuclear explosion'

A nuclear reactor in China has created plasma at a temperature of 50 million Kelvins (49.999 million degrees Celsius or 90 million Fahrenheit) for 102 seconds.

The temperature is thought to be three times hotter than the core of the sun or “roughly the same as a mid-sized thermo-nuclear explosion,” according to the South China Morning Post.

The experiment was done in a machine called the Experimental Advanced Superconducting Tokamak (EAST).

It happened last week at the Institute of Plasma Physics at the Chinese Academy of Sciences in Jiangsu province.

The research team had aimed to maintain a plasma of 100 million Kelvins for over 1,000 seconds, nearly 17 minutes.

However, the length of time that the plasma was sustained and controlled remains significant, as this is one of the main obstacles to implementing nuclear fusion more widely.

Despite the extreme temperatures reached during the experiment, there have been other plasmas produced which have been much higher in different types of machines. However, other super-hot plasmas have not been maintained for as long, largely due to their volatile temperatures and the consequent safety considerations.

The plasma being created is a super-hot gas formed from heating atoms in the magnetic EAST device.

While the technology - in which the atoms fuse at extremely high temperatures to release large amounts of energy - is many decades from being perfected, its proponents believe that it could eventually replace fossil fuels and conventional nuclear fission reactors.

Stephen Hawking's Final Book gives brief Answers to Big Questions

Stephen Hawking's final work was launched by his children on Monday which discuss issues from Existence of God to Time Travel and other big questions. His children completed his final book after he died last year.

Stephen started his book last year to answer the common question which he encountered many times from public. The title of the book is ''Brief Answers to Big Questions''.

His daughter, Lucy Hawking, said he was regularly asked for such question and this book contains his clear and most authentic answers. We all wish he was here to see it published, she added.

What are these big questions and what did he write answers to them?


Is there a God?How Did it All Began?What is inside a black hole?Can we predict the future?Is Time Travel possible?Will we survive on Earth?Is there any other intelligent life in Universe?Should we colonize space?How do we shape the future?Multiple challenges Stephen Hawking says the simplest explanation is that God does not exist and…

Russia Trying to Bring back Extinct Animals

A research facility is being settled in a region of Russia by Vladimir Putin at 4th Economic Eastern Forum which aims to study the remains and clone extinct animals like woolly mammoth, woolly rhinoceros, cave lion and breeds of long-gone horses of old times.





The investment sought for this project is 5.9Million USD.

The animals which could weight 6000 kg have been disappeared from that territory about 4 thousands years ago.

About 80% of the samples of the extinct animals with preserved tissue have been found in this region Siberia .  







Human flights to ISS will begin in 2019

NASA has confirmed that manned space flight will be carried by SpaceX and Boeing in the mid of 2019.SpaceX rocket for ISS will depart in June 2019 while Boeing spacecraft will go in August 2019.
It will be the first US mission since the retirement of the shuttle in 2011.NASA's astronauts are currently using Russian made Soyuz spacecraft and its contract will end in June 2019.NASA said on 4th of the October that it will give monthly updates 


Phil McAlister who is the director of commercial flights in NASA said in Blog that 

New Updates schedule is better but launch schedule may be uncertainHe also said these are new spacecraft and lot of engineering work has to be done before take off.

Back in 2014 both the SpaceX and Boeing received $6.8bn from NASA to build spacecraft that will take humans to ISS.

Boeing has said they will be ready for Orbital Flight Test in March 2019.
The Success of this manned space shuttle will be a great achievement of the commercial space industry, and NASA will …
