World's fastest spinning man made object

Scientists create world's fastest spinning man made object.
The object precisely is not a object but a nano particle which is in dumbbell shaped.
The nano particle is made up of silica and was levitated by using laser in vacuum.
The noted rotation per second (rps) of the nano particle was about 60 billion rps.
Scientists behind this invention are Tongcang Li and Jonghoon Ahn.
Tongcang Li is assistant professor of physics and astronomy and also serve as assistant professor in computer engineering and electrical engineering in Purdue University.
According to Tongcang Li the dumbbell shaped particle was levitated in vacuum with using laser work.
The laser used having capability of working in a straight line and in circle helped in finding two motion of the nano particle
When the laser work in straight line the nano particle vibrates.
When the laser work in circle the dumbbell spins.
The spinning dumbbell work as a rotor and the vibrating dumbbell functions like an instrument which can measure tiny forces and torques
This kind of instruments can work as an excellent torsion balance.
Torsion balance device were used for discovering things like gravitational constant ,density of earth.
According to Tongcang Li that further advancement can help in to study more typical things like quantum mechanics.
Normal people thinks that vacuum is a complete vacant space but physician knows that vacuum a vacant space is a myth ,there are millions of particles which appears for infinitesimal small duration and than disappears .
Tongcang Li and his co scientist want to make a torsional balance with this dumbbell nano particle to study vacuum
Thus this nano particle motions can help in studying about vacuum friction and gravity which is essential for Modern Physics.

Is ISRO in a position to compete with the space organizations of other countries? Where does it rank?

ISRO is one of the biggest contender in space race despite limitations on funding and resources. Many milestones achieved by ISRO like Mars Orbiter Mission, Chandrayaan, 104 satellite launched in orbit on a single rocket put them in the forefront of space race. ISRO might have very less funding in comparison to other major space agency like NASA,JAXA,ROSCOSMOS, ESA, CNSA, CSA but determination of space scientists and there hardwork put ISRO in above elite space groups. There is no ranking system but if I would like to give ISRO a rank and on which most of the people will believe is: 1.NASA 2 ROSCOSMOS 3.CNSA 4.ESA 5.JAXA and ISRO 6.CSA

How Parker Solar Probe will withstand Sun's heat ?

Sun may look calm and beautiful from our earth but it is one of the most ferocious body in our solar system, a body whose mass continuously rises , having millions of nuclear reactions going every second , tingling magnetic lines sun also have strong and constant winds flowing with speed of million miles per hour . Since it is the only star in our reach to study but it is still very difficult to study its behaviour So how? Parker Solar Probe The answer is Parker solar probe made by NASA which will blast off this year to a long journey of around 4 million miles(6.4 million km) from the earth to the sun. The temperature of sun which can rise up to 1 million degree Fahrenheit is strong enough to melt anything approaching it. So how will our small probe will withstand this harsh surrounding? But still the temperature of the solar panels and elements still can go to about 2498 degree Fahrenheit (1370 degree Celsius) so there is necessity to co...

NASA's Chandra X-ray observatory may have observed star consuming a planet for the first time

There are infinite number of stars in our universe. It is always remained an attraction for cosmologist to observe there behaviour. Many observatories are made by space agencies to study astrology and cosmology one of them is NASA's Chandra X-ray observatory It is dedicated in observing behaviour of stars and planets in our galaxy there are many evidence which shows that a star can consume planets. Well,The New report from NASA on findings of NASA's Chandra X-ray observatory which says that they have observe a star in our Milky Way Galaxy around 450 light years away from our earth. the star which which is named RW Aur A is been in consideration of scientist since 1937 . the curiosity in this star increased due to fading of its optical light for few decades and brightening again. But in recent times the frequent dimming of light took attention of scientists A team of scientist with NASA's Chandra X-ray observatory obse...
