Thus, the planets and ourselves, are in fact, all made out of star-stuff! Almost all elements in the universe are literally debris blown off by dying stars — material that is later recycled in the formation of new stars, planets and eventually life. (19) فَاَنۡشَاۡنَا لَـكُمۡ بِهٖ جَنّٰتٍ مِّنۡ نَّخِيۡلٍ وَّ اَعۡنَابٍ‌ۘ لَـكُمۡ فِيۡهَا فٰوكِهُ كَثِيۡرَةٌ وَّمِنۡهَا تَاۡكُلُوۡنَۙ‏, With it We grow for you gardens of date-palms and vines: in them have ye abundant fruits: and of them ye eat (and have enjoyment)― (19). 28:54 Will I ever stream video games? Here, a stunning view of our blue planet captured by NOAA's GOES-East satellite on April 22, 2014. The two lightest elements, hydrogen and helium, were also formed. Vote Now! That would support the idea that in the inner system, the water evaporated, while in the outer system, it didn't. Adjudicating between the two is a challenge, and over the years scientific judgment has swung from one to the other. Do not reproduce without permission. Eventually, the Universe expanded and cooled and huge collections of gas formed into billions of separate galaxies, and billions of stars formed within each. Over time, denser regions of the interstellar medium form into giant interstellar clouds of gas and dust. Wouldn’t the dust in the inner solar system have blocked most of the light/heat of the forming sun. Oceans cover approximately 70.8% or 361 million square kilometers (139 million square miles) of Earth's surface with a volume of about 1,370 million cubic kilometers (329 million cubic miles). Astronomers have found the most distant water yet seen in the Universe, in a galaxy more than 11 billion light-years More and more research suggests that asteroids delivered at least some of Earth's water. In this backscattered electron image, a narrow opal rim surrounds a bright metallic mineral inclusion. Also, in the last several years, newer models seem to show that the Earth retained a lot of water as it formed, and that the oceans might have been present for much longer than anyone thought. But the analyses are based on limited samples, meaning there’s a good chance we’ve not yet heard the final word. So how are the heavier elements, such as oxygen, formed? Advertising Notice But how did it get here in the first place? 22:55 How likely is the Venus phosphine abiotic? It certainly makes a bottle of Fiji seem a little less exotic. They believed that any element heavier than helium had to … The Earth appears blue because large bodies of saline water known as the oceans dominate the surface. "We looked at the chemistry within young molecular clouds containing a thousand times less oxygen than our Sun. Once the hydrogen is used up, helium begins fusing and one of the by products of that process is oxygen. Any less and large areas would have become devoid of all life. Music by Nathaniel Schroeder. The origin of water in the universe Thread starter pixel01; Start date Jan 15, 2008 Jan 15, 2008 state that exploded in what astronomers call The Big Bang. Melting glaciers and rising tides challenge us all, even in an ever more thirsty world. Californians Required to Cover Mouths While Eating, According to Gov. Thus, if the spectrum of water is found to be present in the full spectrum of light that we observe from a given planet, we can infer the existence of water on that planet. Follow LiveScience on Twitter @livescience. Follow us on Twitter: @universetoday Anyone who’s ever seen a map or a globe easily knows that the surface of our planet is mostly covered by liquid water — about 71%, by most estimates* — and so it’s not surprising that all Earthly life as we know it depends, in some form or another, on water. Depending on the mass of the star, all the heavy elements up to iron can be created in succeeding fusion reactions or nucleosynthesis. The atmospheres and interiors of the four giant planets -- Jupiter, Saturn, Uranus and Neptune -- are … By 59:43 Wrap up, Our Book is out! 27:45 How intense is the radiation field at Jupiter? 53:17 Do Mercury and Venus pass in front of the Sun? Earth is quite a watery place. Look at Earth compared to other rocky planets in the neighborhood, and the first thing that would likely jump out is that there's A LOT of water. Helium consists of two protons and two electrons. To be fair, the origin of our planet’s water is an intricate story stretching back some 13.8 billion years to the Big Bang. One is ordinary hydrogen, which has just a proton in the nucleus, and the other is deuterium, also known as "heavy" hydrogen, which has a proton and a neutron. I asked, but my teacher looked as if I’d sought the sound of one hand clapping. Those first generation stars produced elements such as oxygen, which eventually spread across the universe through supernova explosions and stellar winds. 55:43 Is the expansion rate different in the Universe? But this new source was a surprise. Can Scientists Stop the Plague of the Spotted Lanternfly? Zeeya Merali. Meteorite EET 83309 contains tiny fragments of opal, a material that requires water to form. The earliest stars are believed to have been massive but short-lived. However, only at certain temperatures and pressure, like those we find on Earth, would we expect to find liquid water. In this week's live questions show, I answer questions about drilling for microbes on Mars, missions that could survive the surface of Venus, and if anyone else is dissatisfied with the Big Bang. [What Will Happen to Earth When the Sun Dies?]. of a cloud based on the resulting star but some clever people might be able to do it from looking at open star clusters. The oceans contain 97% of our planet's available water. Sorry, your blog cannot share posts by email.

Only light of specific wavelengths can be emitted by atoms of a given element. The discovery may have implications on the origins of life and sources of water throughout the galaxy. Space weathering, which works similar to geological erosion on the Earth, produces water in the rims of tiny particles of interplanetary dust. Water is fairly common in the universe, found everywhere from vast interstellar dust clouds to the orange-red fields of Mars, but most of this water is in the form of ice. Visit our corporate site. Read more. While it’s disputed whether there were particularly “heavy” periods of asteroid and comet bombardment, it is understood that the early Solar System was a tumultuous place. The study's co-author, Amiel Sternberg, added that the cosmic microwave glow back then was hotter, and that the densities of gases were higher. "Astronomy" magazine, February 1999, has an article ("Divining on Mars") on the Mars Polar Lander and the search for water there. Karla Thompson – @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fw Photographs From the Last Quiet Places on Earth. 19:50 Favorite solution to Planet 9? Elon Musk's Starman, Tesla Roadster Made First Close Pass by Mars After 2 Years in Space. http://www.abovetopsecret.com/forum/thread844028/pg1, Join our 836 patrons! Now, given the creation of hydrogen in the Big Bang and oxygen in nucleosynthesis in stars, and the fact that these elements are highly reactive chemically, water should therefore be fairly common in the Universe. https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/, Astronomy Cast: Water is found in primitive bodies like comets and asteroids, and dwarf planets like Ceres. The other 3% is found in atmosphere, on the Earth's terrestrial surface, or in the Earth's lithosphere in various forms and stores. The CfA study asserts that this process occurred earlier than initially thought. How big did the planetesimals get prior to the start of fusion and the solar wind? I guess the collapse rate of the dust cloud would determine how likely pre-fusion planetesimal formation would be, I doubt if it’s possible to determine the temperature, mass etc. The Origin of water in the Universe The Big Bang An estimated 10 to 20 billion years ago, the Universe was in an extremely dense state. Nevertheless, recent observations of their chemical makeups are tipping the scale toward asteroids. Eventually, the Universe expanded and cooled. UPDATE March 2, 2014: recent studies support an “alien” origin of Earth’s water from meteorites, but perhaps much earlier in its formation rather than later. Beirut blast was one of the biggest non-nuclear explosions ever, Fossils of Ice Age manatees discovered in Texas. According to earlier theories, the formation of water in space may have taken a longer time since the oxygen created in the first stars had to disperse and combine with hydrogen molecules in significant amounts. Primordial Black Holes, Episode 687: Open Space 89: Scott Gaudi and the HabEx Mission, Episode 686: Q&A 129: Did Life Get a Ride to Venus from our Missions? ⓒ 2018 TECHTIMES.com All rights reserved. Similarly, each type of molecules has a unique spectrum of light. © Hallis and her colleagues looked at hydrogen isotope ratios in ancient Canadian rocks, some of the oldest rocks on Earth. Later in their lives, when stars go super­nova, the explosions spew these elements into space. What Will Happen to Earth When the Sun Dies? Wondering How to Eat with Mask on? or Privacy Statement Scientists from the Harvard-Smithsonian Center for Astrophysics (CfA) have discovered that water vapor likely appeared in pockets across the universe a billion years after the Big Bang.

Fortunately, the composition of a planet's atmosphere and surface can be partially determined by analyzing the spectrum of light emitted or absorbed by the elements that compose it. Accordingly, each has been fingered as a suspect in the mystery. There are two prevailing theories: One is that the Earth held onto some water when it formed, as there would have been ice in the nebula of gas and dust (called the proto-solar nebula) that eventually formed the sun and the planets about 4.5 billion years ago.
