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...
The Hubble space telescope has made an unexpected discovery of a draft Galaxy in our cosmic backyard,located just 30 million light years away,scientist say.
Research used the NASA/ESA Hubble space telescope to study white dwarf stars within the globular cluster NGC 6752.
According to European space agency (ESA), the aim of the observations was to use these stars to measure the age of globular cluster ,but in process researchers made an unexpected discovery.in the outer fringes area observed wit Hubble's Advanced camera for surveys a compact collection of stars was visible, according to a study published in the journal Monthly Notices of the royal astronomical society:letters.
After careful analysis of brightnesses and temperatures, the astronomers concluded that these stars did not belong to the clusters--which is the part of milky way--but rather they are millions of light years more distant. the cosmic neighbor, nicknamed Bedin 1,is modestly sized, elongated Galaxy.It measures around 3000 light years at its greatest extent--a fraction of the size of milky way.Not only it is tiny,but it is also incredibly faint,researchers said.These properties led astronomers to classify it as a dwarf spheroidal galaxy. Dwarf spheroidal galaxies are defined by their small size,low luminosity,lack of dust and odd stellar populations. 36 galaxies of these type is already known to exist in the local group pf galaxies, 22 of which are satellite galaxies of milky way. while dwarf spheroidal galaxies are not uncommon,Bedin 1 has some notable features. Not only it is one of just a few dwarf spheroidal that have a well established distance but it is also extremely isolated.
it is about 30 million light years from the milky way and 2 million light from the nearest plausible large galaxy host,NGC 6744. this makes it possibly the most isolated small dwarf galaxy discovered to date.From the properties of its stars,astronomers were able to infer that the galaxy is around 13 billion old nearly as old as universe itself.
Due to is isolation--which resulted hardly any interaction which one galaxies --and its age, Bedin 1 is the astronomical equivalent of a living fossil from the early universe. The discovery of Bedin 1 was a truly serendipitous find.
