Feedback loops: How nature gets its rhythms - Anje-Margriet Neutel The music in this lesson was composed by Ross Allchurch. Feedback What is feedback? It is a process that is the result of mutual causal interaction: X affects Y and Y affects X. LHC Machine Outreach The Large Hadron Collider (LHC) is built in a circular tunnel 27 km in circumference. The tunnel is buried around 50 to 175 m. underground. It straddles the Swiss and French borders on the outskirts of Geneva. The first beams were circulated successfully on 10th September 2008. Unfortunately on 19th September a serious fault developed damaging a number of superconducting magnets. Solar System Planet Earth A European researcher has interpreted carvings in a 32,500-year-old ivory tablet as a pattern of the same stars that we see in the sky today in the constellation Orion. The tablet is a sliver of ivory from the tusk of a mammoth — a large woolly animal like an elephant. Mammoths are extinct today. Carved into the ivory is what appears to be a carving of a human figure with outstretched arms and legs.

Good(night) Moons Rising Paper Plate Education"Serving the Universe on a Paper Plate" The classic children's book Goodnight Moon by Margaret Wise Brown has excellent illustrations by Clement Hurd. Notice the location of the moon in the great green room's window. The clocks--on the mantle and on the nightstand--advance in 10-minute increments as the full moon rises appropriately in the evening. Two clocks show the passage of time. Meanwhile, the painting over the fireplace of the cow jumping over the moon accurately portrays a waxing crescent moon setting in the evening sky. Bad Moons Comments Paper Plate Education"Serving the Universe on a Paper Plate" What's wrong with these pictures? Plenty! As detailed in the Bad Moons Rising activity, a random sampling of children's books at a small local library reveals frequent errors in how moon phases are depicted. Below are excerpts from the books and brief descriptions of the story.

Paper Plate Education Welcome to a unique genre of education materials. Paper Plate Education is an initiative to reduce complex notions to simple paper plate explanations. This website promotes innovative hands-on Activities that you can experience across a range of interests, at varying degrees of complexity, and at a low price—all with common paper plates. Check out the exciting new material that has been uploaded to this website recently. Paper Plate Education evolves as educators contribute to its content.

Is The Simpsons actually set Down Under? Astronomer claims Springfield CAN'T be in America because latest episode shows the moon as seen in the southern hemisphere Less than two weeks after The Simpsons producer dismissed a theory that Homer has been in a coma for two decades, an astronomer has come up with another conspiracy: Springfield is in the southern hemisphere. In the latest episode of the show, SpaceX's Elon Musk guest starred and spends time at the Simpsons' home. At one point he stands by the dining room window, looking out at the night sky as the family sits behind him eating dinner.

Lunar phase The phase and libration of the Moon for 2013 at hourly intervals, with music, titles and supplemental graphics. Animation of the Moon as it cycles through its phases, as seen from the northern hemisphere. The apparent wobbling of the Moon is known as libration. Total Solar Eclipse 2017 - "Close" is NOT close enough! Our Letter to the editor, in response to his readers' possible decision to forsake the path: I am a veteran of 11 total solar eclipses, and I operate the site – which has as its primary mission the offering of information regarding the safe, enjoyable viewing of the total solar eclipse which will occur on August 21, 2017. Our task is to convince people who are not in the path of totality, that they simply must travel into the path, in order to see one of the most spectacular things they will ever see in their life. The task is difficult, because it is natural to believe that if one is “close” to the path, one will see something that is “pretty good”. But just as the person who only smells the meal outside the steakhouse remains hungry, so too do those who observe the eclipse from outside the path of totality end the day wondering what, indeed, all the fuss was about. Get thee to the path!

Everyday Classroom Tools: Table of Contents Welcome to the Everyday Classroom Tools web site! For the past three years, Smithsonian Astrophysical Observatory has worked with elementary schools in Massachusetts to develop an integrated, inquiry-inspiring curriculum framework that brings science and the Internet into the everyday life of the elementary classroom. Our goal has been to infuse the Spirit of Inquiry into every school subject, so that students and teachers can approach learning as a life-long exploration of the world around us. The result of our efforts is embodied in the "Threads of Inquiry: Observing the World Around Us", a series of ten hands-on, minds-on investigations that focus on the changing seasons and other aspects of our everyday experience. Developed according to the National Science Education Standards, the Threads can guide you and your class towards a practical and enthusiastic understanding of scientific inquiry. This work has been supported by the NASA Learning Technologies Project.

TED Ed: The Moon Illusion This is What Outer Space Does to Your Body NASA astronaut, engineer, and former football player Leland Melvin explains how the human body changes when it leaves the confines of Planet Earth.

Earthshine, the Moon's Darker Side With a subtle beauty all its own, the earthshine we see glowing in the lunar night invites us to consider Earth's many connections to the Moon. A 2-day-old crescent moon is filled out by light twice reflected — first by Earth and then from the moon back to our eyes. Bob King This week's crescent Moon offers more than two horns to hang your hat on. Take a close look, and you'll see an entire circle of moonlight. Sunlight illuminates the bright crescent, but the remainder of the disk would be utterly black and invisible were it not for earthshine.

Galleries - NASA Solar System Exploration Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms. This annotated artist's concept illustrates the new view of the Milky Way, along with other findings presented at the 212th American Astronomical Society meeting in St. Louis, Mo.
