The Planets Today : A live view of the solar system 10 Best Channels for STEM Education on YouTube Was Formula 1 in your syllabus growing up? Probably not, but times are changing. As of this year, Formula 1 cars have made the grade, and will be appearing in public school curriculum. When you look at the speed and design of our racecars and their performance on the track, NASCAR represents a unique platform to teach math and science. Acceleration Nation isn’t alone in pushing for STEM education. Why Is STEM so Important? The STEM acronym breaks down into four disciplines: Science, Technology, Engineering, and Mathematics. STEM education prioritizes active sub-disciplines like astronomy, biochemistry, biomechanics, civil engineering, mathematical biology, nanotechnology, neurobiology, and robotics – to name just a few. We need to be raising the next generation of critical thinkers and innovators; more, we need motivated teachers who can connect the dots. But Why Is It so Critical? Reason #1 – For our children. It’s the technology age. Reason #2 – For the world. STEM is an American concept.
Night Sky Constellations Naming History | Skywatching There are 88 officially recognized constellations in the sky, and these astronomical patterns have a fascinating and long history. Forty-eight of the constellations are known as ancient or original, meaning they were talked about by the Greeks and probably by the Babylonians and still earlier peoples. After the 15th century, with the age of the great discoveries and worldwide navigation, the southernmost parts of the sky became known to man and had to be charted. Furthermore, across the entire sky were large gaps filled chiefly with dim stars between them. In more recent times people have invented the modern constellations to fill up some of these spaces. In our current evening sky, roughly between the bright star Capella and the Big Dipper’s bowl are two examples of modern constellations. The other is the Lynx, one of only two animal constellations with identical Latin and English names (the other is Phoenix). “I am very fond of cats," he said, explaining his choice.
Science Explained: Where Did the Big Bang Happen? Where's the Center of the Universe? Timeline of the universe after the big bang (Image Credit: NASA) The Big Bang happened some 13 billion years ago. Before this time, as best we can tell, there was no time (or space, for that matter). In short, we can’t go back to a time before the Big Bang. But what about the Big Bang itself? This is actually a pretty common question. However, what many people don’t realize about the Big Bang is that it was not matter exploding into empty space. When the Big Bang happened, everything was in one location. To be absolutely clear, space was literally growing everywhere. And here’s the thing: Space is still stretching out in much the same manner. Image of the expansion of the universe. Because this expansion happened everywhere, the term “the center of the universe” doesn’t really mean anything. How far we can see is called our “light horizon.”
Has This New Discovery By Astronomers Confirmed there is a 'Planet X'? Astronomers have extended the range of our Solar System with the discovery of a new 'dwarf planet' orbiting our Sun. The planet, currently technically labeled '2012 VP113', has an elliptical orbit that brings it to within 80AU of the Sun (an 'AU' is the unit of distance from the Sun to Earth) at perihelion (closest point in its orbit to the Sun) - some three times the distance from the Sun to Neptune - while it gets as far as 450AU away at the other end of its orbit. The object is not unique: astronomers have previously discovered another similar dwarf planet, named 'Sedna'. An intriguing coincidence is that the current positions of both Sedna and 2012 VP113 - which are also near both their perihelions - are very similar, leading to some speculation of an unknown, massive body orbiting our Sun well beyond our current sensing abilities - a 'Planet X': The latest work has already thrown up an intriguing possibility. Link: A second Sedna!
Los Planetas del Sistema Solar Su Trayectoria, Datos y Caracteristicas Inicio » Temas Científicos » Los Planetas del Sistema Solar Su Trayectoria, Datos y Caracteristicas LOS PLANETAS DEL SISTEMA SOLAR: El sistema solar consta de nueve planetas. A todos ellos, excepto Mercurio y Venus, los acompañan satélites en número variable, desde la Tierra, que solamente tiene uno (la Luna), hasta Júpiter, alrededor del cual giran once. Entre Marte y Júpiter hay multitud de pequeños cuerpos, cuyo número sobrepasa los dos millares. Además de la Tierra, los planetas se dividen en dos grupos claramente diferenciados. La excentricidad orbital de los planetas aumenta de manera inversa a su diámetro: en los más grandes alcanza algunas centésimas y crece notablemente para los pequeños. Planeta Mercurio: El pequeño y rocoso planeta Mercurio tiene el nombre del veloz mensajero de los dioses romanos, por su rápido paso a través del cielo, visto desde la Tierra. MERCURIO El planeta más próximo al Sol. Planeta Venus, es el planeta que está más cercano a la Tierra.
Radio Waves from Brown Dwarf Discovered An artist's impression of a brown dwarf similar to J1047+21. Using the radio telescope at Arecibo, Puerto Rico, a team of astrophysicists from Penn State have discovered radio emissions from a brown dwarf in the constellation Leo. 33.6 light years away, this ultra-cool star, named J1047+21, is only 5 times hotter than Jupiter. Penn State astronomers using the world’s largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous record for the lowest stellar temperature at which radio waves were detected. The team from Penn State’s Department of Astronomy and Astrophysics and the Center for Exoplanets and Habitable Worlds, led by Alex Wolszczan, the discoverer of the first planets ever found outside our solar system, has been using the giant 305-meter (1000-foot) telescope to look for radio signals from a class of objects known as brown dwarfs.

Myter og sagn om stjernebildet Orion Om vinteren er Orion lett å få øye på. Ta utgangspunkt i de tre stjernen som utgjør beltet. De er som perler på en snor og den midterste av stjernene i beltet heter Alnilam, og det betyr perlerad. Den nordligste av de tre stjernene heter Mintaka som betyr kjempens belte. Den sørligste av de tre stjernene er en dobbeltstjerne som heter Alnitak. Orions belte er et godt utgangspunkt for å finne andre stjerner på vinterhimmelen. Orions høyre skulder er den rødlige stjernen Betelgeuse. Et stykke under beltet finner du Rigel, en blåhvit stjerne som utgjør Orions venstre fot og Saiph som danner hans høyre fot. Foran Orion, halvveis til Tyren er det en bue av svake stjerner. Orion var ingen vanlig dødelig. Rødfarge på himmelen og dugg på blomster og blader En gang truet Orion med å drepe alle dyrene på jorda, fordi han mente at han var så flink en jeger. En gang lå Orion og sov sammen med hundene sine Sirius og Procyon. Hvorfor legger påskeharen egg? Haren sprang og hadde det fint i skogen.
NASA space assets detect ocean inside Saturn moon NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence that Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes. Researchers theorized the presence of an interior reservoir of water in 2005 when Cassini discovered water vapor and ice spewing from vents near the moon’s south pole. The new data provide the first geophysical measurements of the internal structure of Enceladus, consistent with the existence of a hidden ocean inside the moon. “The way we deduce gravity variations is a concept in physics called the Doppler effect, the same principle used with a speed-measuring radar gun,” said Sami Asmar of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. The gravity measurements suggest a large, possibly regional, ocean about 6 miles (10 kilometers) deep beneath an ice shell about 19 to 25 miles (30 to 40 km) thick.
Electricity for kids - and everyone else: A simple introduction! Advertisement by Chris Woodford. Last updated: April 14, 2016. If you've ever sat watching a thunderstorm, with mighty lightning bolts darting down from the sky, you'll have some idea of the power of electricity. Electricity is the most versatile energy source that we have; it is also one of the newest: homes and businesses have been using it for not much more than a hundred years. What is electricity? Electricity is a type of energy that can build up in one place or flow from one place to another. Static electricity Static electricity often happens when you rub things together. Have you ever walked across a nylon rug or carpet and felt a slight tingling sensation? Lightning is also caused by static electricity. Photo: Lightning in South Lakewood, Colorado. How static electricity works Electricity is caused by electrons, the tiny particles that "orbit" around the edges of atoms, from which everything is made. Suppose you rub a balloon on your pullover over and over again. Electric circuits
Mystery over the giant cosmic explosion of 774AD, which has left absolutely no trace - except deep within the rings of two cedar trees By Eddie Wrenn Published: 12:10 GMT, 4 June 2012 | Updated: 16:39 GMT, 4 June 2012 The clues are in these rings: The rings capture microcosmic traces of particles in our skies - and tell us an explosion occurred It is a mystery which is truly beyond even Sherlockian scale - a cosmic explosion which left no trace behind except deep within the bark of two cedar trees. Fusa Miyake, of the Nagoya University in Japan, studied the growth rings of two trees dating back 1,200 years - and discovered that an explosion of epic proportions occurred between 774 and 775AD. But there is no record of something happening in our skies in that period - except perhaps for one tiny, obscure account by a 13th-century historian. The problem - and this is where we need to call in Mr Holmes of Baker Street - is that there should be a record. Carbon-14 forms when cosmic rays - generally caused by massive solar flares, or by supernovae - interact with nitrogen and oxygen in our atmosphere.
