What is “down,” and what is “up” of gravity?

What is “down,” and what is “up” of gravity?

A real place where things weigh nothing and where there is no up or down. Why is it that the oceans do not flow off the earth? What is gravity? What is “down,” and what is “up”? There is a place where nothing has weight; where there is no “up” or “down”; where nothing ever falls; and where, if people were there, they would float about with their heads pointing in all directions. This is not a fairy tale; every word of it is scientifically true. Gravity, or gravitation, is…

Things we should know about these amazing ocean planet

Things we should know about these  amazing ocean planet

An ocean planet, aquaplanet or water world[1] is a hypothetical type of exoplanet wherein the surface is completely covered by water, and a substantial portion of its mass is water. Formation Planetary objects that form in the outer Solar System begin as a comet-like mixture of roughly half water and half rock by mass. Simulations of Solar System formation and of extra-solar system formation have shown that planets are likely to migrate inward (i.e., toward the star) as they form.[2][3][4] Outward migration may also occur under particular conditions.[4] Inward migration…

what it was like before big bang

what it was like before big bang

Now a team of mathematicians from Canada and Egypt have used cutting edge scientific theory and a mind-boggling set of equations to work out what preceded the universe in which we live. In (very) simple terms they applied the theories of the very small – the world of quantum mechanics – to the whole universe – explained by general theory of relativity, and discovered the universe basically goes though four different phases. More importantly they discovered what came before this universe was.. another universe or more accurately another ‘cosmological phase’….

Amazing strange dwarf planet discovered in the solar system

Amazing strange dwarf planet discovered in the solar system

SCIENCE Will this newly discovered dwarf planet help astronomers find ‘Planet Nine’? Researchers hope techniques used to discover dwarf planet 2014 UZ224 will help find the enigmatic ‘Planet Nine.’ By Weston Williams, Staff OCTOBER 11, 2016 Travis Heying/The Wichita Eagle/AP/FileView CaptionAbout video adsView Caption About 8.5 billion miles away from the center of the solar system, a small dwarf planet orbits our sun. Unknown and undetected for millennia, this planetary body, known as 2014 UZ224, is among the most distant objects in our solar system, more than twice as far…

stunning wonderful universe got a lot bigger

stunning wonderful universe got a lot bigger

Astronomers used to think the universe contains 100-200 billion galaxies. Now, the population estimate has jumped up to 2 trillion. The universe just got a lot bigger. Thanks to some new data from Hubble, scientists have calculated that there must be at least 2 trillion galaxies in the universe–a massive population spike from the previous estimates of a measly 100-200 billion galaxies. We haven’t yet set eyes on the vast majority of these, because they are small, faint, and very far away. “It boggles the mind that over 90 percent…

powerful way to understand galaxies and stars

powerful way to understand galaxies and stars

CATS is a long-term survey aimed for an enhanced near-IR study of the structural, chemical, star formation, and kinematic evolution of distant field galaxy subcomponents on sub-kpc scales. This is possible by using adaptive optics (AO) on an 8-10m class telescope that has diffraction-limits in the near-IR of 0.05 arcsec, which is 3x-4x better than is possible with HSTs 2.4m mirror at a similar wavelength. This resolution corresponds to the sizes of bulges, disks, bars, spiral arms, and merger/interaction or lensing signatures at redshifts z > 0.5 and improves the…

what is orion nebula ?

what is orion nebula ?

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000…

Largest galaxy in the known universe

Largest galaxy in the known universe

There are about More than 100 billion galaxies in the observable universe. For roughly 13 billion years they’ve swarmed around each other, colliding and merging, undergoing rapid star formation and suffering periods of drought, where no new stars are born. They range in size and shape from small, dwarf galaxies to the beautiful and graceful mid-range spiral galaxies to the gigantic and ancient ellipticals. The smallest, the dwarf galaxies, can be as small as 200 light years across and not much more massive than a star cluster. They contain as…

what we know about planet x?

what we know about planet x?

we all are heard about strange planet called planet x or nibiru. But what is exactly is planet x? How do we know that exists beyond our solar system. The stories we hear about planet x is strange and mysteries. so lets get some facts about planet-x. Dozens of large celestial bodies beyond Neptune in perturbed orbits have been discovered, yielding stronger astronomical evidence that the elusive world, Planet X (or Planet Nine, as scientists prefer), exists somewhere in the outer solar system. A new study being presented by the…

what is super earth

scientists are discovering amazing planets and stars using different methods because of the technological advancement we can find out the newer and amazing planets one of the greatest discovery is super earth planets. so what is super earth actually? super earths are similar to earth temperature and its atmosphere and which orbits in habitable zone where its atmospheres are almost close to the earth atmosohere. For the past two decades, astronomers have conducted concentrated searches for extrasolar planets, planets orbiting other stars. So far, astronomers have found about 2,000 extrasolar…
