Today I found out that the moon isn't as old as the Earth and was formed approximately 3050 million years after the Solar System based on what is called the giant impact theory'. Although no one can say for sure exactly how our moon came to be, there a few hypothesis and theories of which the the giant impact theory' is the most compelling and widely accepted. In this theory, the Earth had no moon until it was struck by a rogue planet which instantly vaporized. The impact is said to have created a cloud that reached roughly.
13,700 miles or 22,000 kilometers high, where it condensed into solid particles that orbited the Earth. Over time they aggregated into larger moonlets, which eventually combined to form the moon we know today. This theory is supported by quite a bit of evidence such as even though the Earth has a large iron core and the moon does not, the moon has exactly the same oxygen isotope composition as the Earth, unlike other planets formed in other parts of the Solar System. This indicates the moon should have been formed from material in Earth's neighborhood. Another significant.
Piece of evidence comes from the oldest record of Earth's ocean tides ever found, which were 3.2billionyearold rocks from South Africa. Pinstriped circular sandandsilt layers in the rocks were deposited by daily, fortnightly and monthly tidal cycles. If the moon formed elsewhere, then was captured intact by Earth's gravity as some theories state, the moon's orbit would have been extremely elliptical and tidal rock layers would not have shown such normal cycles. Computer simulations modeling a giant impact are consistent with measurements of the angular momentum of the EarthMoon system, and the small size of the lunar core. They also show.
That most of the Moon came from the impactor planet and not from Earth. The postimpact mixing of the vaporized material between the forming Earth and Moon could have equalized their isotopic compositions, but this again is just speculation. Bonus Facts The rotation of the moon i.e the time it takes to spin once around on its own axis takes the same amount of time as the moon takes to complete one orbit of the Earth, about 27.3 days. This means the moon's rotation is synchronized in a way that causes the moon.
To show the same face to the Earth at all times. One hemisphere always faces us, while the other always faces away. The lunar far side aka the dark side has been photographed only from spacecraft. The South African rocks indicating tidal patterns indicate that 3.2 billion years ago, the moon orbited Earth in perhaps a 20day month and was 25percent closer to Earth than it is today. At that time, the Earth would have spun faster, so there would have been about 550 days in a year. Temperature on the moon's surface is said to range from 243 degrees Fahrenheit 117.
Degrees Celsius for two weeks at a time the lunar day lasts about a month, then, for an equal period, the same spot is in the dark and cools to about 272 degrees Fahrenheit 169 degrees Celsius. The saying once in a blue moon refers to the occurrence of two full moons during one calendar month. The Moon is bigger than Pluto. And at roughly onefourth the diameter of Earth, some scientists think the Moon is more like a planet. They refer to the EarthMoon system as a double planet. Pluto and its moon Charon are also called a doubleplanet system by some.
Kepler Conference on This Week NASA
A full house onboard the International Space Station NASA's new top scientist on the next mission to Mars And big news from the planetfinding Kepler mission Those are some of the stories trending, This Week at NASA! During the Kepler Science Conference at Ames Research Center, the science community discussed the latest news from the Kepler mission's hunt for exoplanets. which are planets outside our solar system Among the findings 833 newly discovered candidate planets 10 of those orbiting in their sun's habitable zone a distance.
At which their surface temperature may be suitable for liquid water. The Expedition 38' crew, including NASA Flight Engineer Rick Mastracchio launched from Kazakhstan on a sixhour trip to the International Space Station. Onboard with them was the Olympic torch which, as part of the traditional torch relay, is headed by way of spacewalk to Sochi, Russia for February's winter games. The arrival of Mastracchio, Soyuz Commander Mikhail Tyurin and JAXA Flight Engineer Koichi Wakata brought the number of ISS crew members to nine for just the second time ever AND it's the second time three Soyuz spacecraft have been docked to the.
Station at the same time. At Kennedy Space Center, NASA's new chief scientist, Dr. Ellen Stofan met with the media to discuss the upcoming launch of the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft. The solar wind comes in and is actually stripping atoms off the top of the atmosphere of Mars and so MAVEN comes in is gong make the measurements, understand that process, understand what's going on now that will help us say what happened on Mars in the past. MAVEN launches from Cape Canaveral Air Force Station later this month on its mission.
To study Mars' atmosphere. For the first time, a team of NASA and international scientists has a detailed understanding of the effects of a small asteroid impact on Earth. The unprecedented data was obtained from the airburst of a meteoroid over the Russian city of Chelyabinsk on Feb. 15. Scientists now have established a new benchmark for future asteroid impact modeling, which has implications for the study of nearEarth objects, such as asteroids and the development of strategies for planetary defense. The first functional satellite built by high school students is scheduled for a ride to.
Space November 19 from Wallops Flight Facility. The small satellite called TJCubeSat was developed as a club project over the past eight years by students at Thomas Jefferson High School for Science and Technology, outside Washington, DC. Part of something that goes into space, part of something that's making history. It's just like a really unbelievable experience for me and everybody who's worked on it so far. It's quite a student effort in investing the initial time in getting this project off the ground. TJCubeSat is primarily an educational outreach tool. It features a website where the.
Administrator Bolden on Kepler Mission Findings
KEPLER REMINDING THE WORLD WHY WE CONTINUE TO EXPLORE This week NASA is holding a conference of 400 scientists from around the world to discuss the findings that continue to emerge from our amazing Kepler mission. These scientists, both inside and outside government, will continue to explore potential planets outside our solar system for years to come based on the spacecraft's groundbreaking work. Conference participants are reporting many amazing findings. Among these include a stunning result, which found that there maybe many more Earthlike planets than previously thought in the Milky Way that reside in the habitable zone..
The science that Kepler has made possible reminds us just how important NASA's work is to understanding our universe and why we need to continue to push the boundaries of exploration. Kepler was designed to survey our region of the Milky Way galaxy to discover Earthsize and smaller planets in or near the habitable zone and determine what fraction of the hundreds of billions of stars in our galaxy might have such planets. Although the Kepler mission ceased operation earlier this year, we've already confirmed 167 planets orbiting stars in.
Other solar systems, with the planet candidates list currently standing at 3538. As NASA plans missions to an asteroid and Mars, and just marked 13 years of continuous habitation aboard the International Space Station, we're learning to live and work off planet for the long term. We're working hard to revolutionize humanity's ability to reach and live in other places than our home planet, and these Kepler findings are a fascinating reminder that there may be other worlds like ours that could also harbor life or be habitable. While we continue to learn more about these worlds, missions.
Like Juno and New Horizons will magnify our understandings of worlds closer to us. MAVEN, launching later this month, will add to our growing body of knowledge about Mars in preparation for a human mission there in the 2030s. Before that, NASA plans to locate and redirect an asteroid to lunar orbit where astronauts can visit one of these ancient building blocks of the solar system by 2025. These incredible achievements would have been unthinkable just a few years ago, but with our steady and strategic investments in science, technology and human exploration we.
1000 exoplanets, baldness cures, and trees full of gold Truthloader Investigates
Hello and welcome to Truthloader's science in 90 seconds, big stories, little bulletin. And first up. Like planets Well you've got plenty to choose from the number of confirmed expoplanets has hit the symbolic 1,000 milestone. Thanks to the likes of the now retired Kepler space telescope, humanity has discovered close on 4,000 potential exoplanets, with 1010 confirmed, 12 of which are potentially habitable. The milestone hasn't been universally welcomed though, some have said it demonstrates just how far behind we are in learning about the cosmos due to a lack of funding.
Space. On top of your head. The final frontier. The mission of science To baldly grow where no hair has grown before. OK ok, but jokes aside, despite the miracles of medical science, a cure for baldness has so far remained elusive. So scientists from the US and UK have united to scratch their shiny heads over the problem and have come up with a promising idea growing hair from tissue of other bodily hair. Sounds simple, but whilst this has worked before with animal samples, human hair has a tendency to regrow as skin. But the team found that.
Plankton Net Toy Dr. Morris Testimonial
My name is Dr. Kimo Morris, I am a biology professor at Santa Ana College My job on this project was to advise the designers on how a plankton net works for real scientists and from that, they came up with this really cool design The mesh here is perfect for catching microscopic plankton and for actually viewing them right onsite. When kids go to the beach, they absolutely love collecting things and yet there's so much about the ocean that they never get exposed to this sort of a toy actually lets them explore being a scientist and see a.
Update One direction no, not the band
Hello, and greetings from the middle of the German countryside. Thank you for your comments on my last tutorial. 2008PowerStrokeF450 wants to know if I'm still in Germany, and the answer is Yes, I only moved a few miles up the road. Literally. rubadux wants to know who needs books, which is a fair point for acoustics, you just need to hang a pair of curtains. It's not that I need books, it's that I have books and they've got to go somewhere, so they might as well go somewhere where they're doing a bit of good.
'Cause nobody ever reads them. anmoose, I know exactly what you mean when you say we never realise just how much stuff we have until we move. It seems to me that every time we do move, we have to put into our new house about twice as much as we took out of our old house, and I really don't understand how that happens. thejonusvlog has moved five times in 20 years, which averages out at about once every 4 years, which is not too bad I've known worse. The most popular comment was by Seegalgalguntijak,.
Who says that when my house is finally furnished perhaps I could give a tour of it. And since that is the most popular comment, it seems that that's what you all want. Well, that is going to take some time, I'm afraid. So until then, I thought I'd give you a tour of the village. I say village of course, it's a municipality with a total of eight named places, and a combined total population at the end of last year of 1,859. One of the things about such a tiny place as this.
Is that most of the places that are important or interesting, like the church or the town hall, are all in one place. And so this means that when they decided to put up pretty little signs telling everybody where everything is, most of the arrows pointed in the same direction. And of course, because this is in the middle of the country, one of the biggest industries, apart from agriculture, around here is timber, and so there's a massive sawmill. It doesn't look as if there's anything going on, but actually there is.
82nd Fifth Celestial by Clare Vincent
The Celestial Globe is a threedimensional map of the stars. Inside is a mechanical device for the sixteenth century is absolutely mind blowing. It was the work of the clock maker Gerhard Emmoser for the Holy Roman Emperor Rudolf II. Rudolf had an interest both in art and in the sciences and even the pseudosciences. There are traces of astrology in the astronomy of the period. The globe itself is engraved with constellations copied from a globe by Gerard Mercator. There are extra constellations, and they both turn out to be.
Unclothed ladies, probably made specifically to please the emperor. It moves to show you the position of the stars overhead on the day that you need. A calendar revolves, hidden in the horizon line. A lovely little sun rides along and gives you the position of the sun in the zodiac for each day of the year. The disc tells you the time of day. You could also simply turn the thing yourself and find out an individual star at a given time. This is clearly made for the delectation of the emperor, so that he could show.
He knew about these things. Pegasuss relation to astronomy comes through a very complicated history of Pegasus and the Muses from antiquity. Rudolf would have understood this trope I think a very beautiful and poetic way of expressing comes through a very complicated history the science of astronomy rests on the wings of geometry and arithmetic. This colored the rest of what I did in the world of art history in a way that I cant say that any other object in the collection has. As a piece of purely decorative art,.
