Quantum tunnel it is a new concept of modern physics. Since last decade quantum mechanics is successor over classical physics rules at quantum level. It will help us better for understanding of matter. Starting from matter, it a composition of atoms , nuclei , nucleons , electron, etc. their size from 10^-11 to 10^-15 . At this quantum level ,long range forces (like Gravity)become very weak. And strong forces like nuclear force, Wander waal force ( little weak) , Electrostatic force , Inter-atomic force of Gluons came up. Due to this it changes the whole structure of time at quantum level. Let's us understand how it works -- Nucleus is final density of matter it is equivalent to density of atom at center of Black holes,or other stellar bodies in universe. According to theory of Relativity , gravitational force can bend space and time and increase in gravitational forces literally Squeeze time and space. ( Ex: any stellar massive body) . Then what is its relation to Quantum le...
Scientists have discovered 12 new moons orbiting Jupiter ,bringing the total number of natural satellite circling around king planets to a whooping 79 .
The finding include 11 " normal" outer moons , and one that scientist called an "odd ball".
Researchers , led by Scott Sheppard from Carnegie Institution for science in US , first spotted the moons in last year while they were looking for a possible massive planet far beyond Pluto.
"Jupiter just happened to be in the sky near the search field where we where looking for extremely distant solar system object, so we where serendipitously able to look for new moons for Jupiter while same time looking for planet at the fringes of our solar system," said Sheppard."It takes several observations to confirm an object actually orbits around Jupiter.
So, the whole process took a year," said Gareth Williams from the International Astronomical Union. Nine of new moons are part of a distant outer swarm of moons that orbit it in the retrograde, or opposite direction of Jupiter's spin rotation.
These distant retrograde moons are grouped into a least three distinct orbital grouping and are thought to be the remnants of three once-larger parent bodies that broke apart during collision with asteroids ,comets and other moons. The newly discovered retrograde moons take about two years to orbit Jupiter.
Two of these discoveries are part of closer, inner part of moons that orbit in prograde, or same direction as the planets rotation. These inner prograde moons all have similar orbital distances and angle of inclination around Jupiter and so are thought to also be fragments of a larger moon that was broken apart. this two newly discovered moons take little less than a year to travel around Jupiter.
"Our other discovery is a real odd ball and has a orbit like no other known Jovian moon. It's also likely Jupiter's smallest known moon, being less than one kilometer in diameter ," Sheppard explained. This new "oddball" moon is more distinct and more inclined than the prograde group of moons and takes about one and half years to orbit Jupiter
So, unlike the closer in prograde group of moons, this new oddball prograde moon has an orbit that crosses the outer retrograde moons.
As a result, head on collision are much more likely to occur between the "oddball" prograde and retrograde moons, which are moving in opposite directions. "this is an unstable situation . Head on collision would quickly break apart and grind the objects down to dust," said Sheppard. It's possible the various orbitals moon grouping we see today where formed in distant past through this exact mechanism. The team thinks this small "oddball" prograde moon could be the last remaining remnant of a once larger prograde moon that formed some of the retrograde moon grouping during during past head on collisions.
The name Valetudo has been proposed for it, after the roman God Jupiter's great grand granddaughter, the goddess of health an hygiene.
