Your Sky by John Walker Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet. A control panel permits customisation of which objects are plotted, limiting magnitudes, colour scheme, image size, and other parameters; each control is linked to its description in the help file. Your Sky provides three ways to view the sky with links, where appropriate, among the various presentations. Sky Map The sky map shows the entire sky as viewed from a given location at a specified time and date. Horizon Views Horizon Views, showing the stars above the horizon as seen from a specified observing site at a given date and time. The Virtual Telescope Your Sky help Related Software
Magnifying the Universe Embed this infographic on your site! <iframe width="500" height="323" scrolling="no" src=" frameborder="0" allowfullscreen></iframe><br />Copyright 2012. <a href=" the Universe</a> by <a href=" Sleuth</a>. The above is an interactive infographic. Introduction: This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. While other sites have tried to magnify the universe, no one else has done so with real photographs and 3D renderings. We hope you have a blast magnifying the universe, know that each time you zoom in a depth, you're magnifying the universe 10x ... and every time you zoom out, the bigger objects are 1/10th of their prior size.

The end of the net as we know it | Broadband | Features Posted on 21 Jan 2011 at 13:34 ISPs are threatening to cripple websites that don't pay them first. Barry Collins fears a disastrous end to net neutrality You flip open your laptop, click on the BBC iPlayer bookmark and press Play on the latest episode of QI. But instead of that tedious, plinky-plonky theme tune droning out of your laptop’s speakers, you’re left staring at the whirring, circular icon as the video buffers and buffers and buffers... That’s odd. Net neutrality? The free, unrestricted internet as we know it is under threat. No such thing as net neutrality It’s worth pointing out that the concept of net neutrality – ISPs treating different types of internet traffic or content equally – is already a busted flush. “We have an unbelievably good, differentiated network at all levels, with huge levels of widespread discrimination of traffic types. Indeed, the major ISPs claim it would be “unthinkable” to return to an internet where every packet of data was given equal weight.

Space.com Buy This Infographic as a Full-Size Poster Astronomers have discovered more than 700 alien planets beyond the solar system, and the count is rising all the time. Some are large and hot, and others are smaller and cooler, but scientists are still on the lookout for an Earth twin. They just got closer, with the announcement Dec. 5 of a planet found by NASA's Kepler space telescope to lie in the habitable zone around its star where liquid water, and perhaps life, could exist.

The Planets Today : A live view of the solar system Now trending: the internet could usher in an Independent revolution that topples the two-party establishment | CAIVN As the country remains highly polarized and chronically dissatisfied with the performance of the two major parties, the internet, and advent of social media in particular, could catalyze the historic campaign of an Independent presidential candidate as early as 2012. Joe Trippi, the internet guru behind Howard Dean’s remarkable 2004 presidential campaign and the mind behind Jerry Brown’s 800 number fundraising effort during his 1992 presidential run, echoed this sentiment at the South by Southwest Interactive festival’s recent gathering. Author of the book The Revolution Will Not Be Televised: Democracy, the Internet, and the Overthrow of Everything, Trippi discusses how he leveraged the internet’s enabling ability of allowing a two-way interaction between candidate and voter to spur a people-driven movement for Howard Dean’s 2004 presidential run. Aided by the fluid medium of the internet, the impending doom of the two-party system might just arrive sooner rather than later.

Hubble's Panoramic View Several million stars are vying for attention in this NASA/ESA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, located in the heart of the Tarantula nebula. 30 Doradus is the brightest star-forming region in our galactic neighbourhood and home to the most massive stars ever seen. The nebula resides 170 000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region in our galaxy is as large or as prolific as 30 Doradus. The image comprises one of the largest mosaics ever assembled from Hubble photos and consists of observations taken by Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys, combined with observations from the European Southern Observatory’s MPG/ESO 2.2-metre telescope that trace the location of glowing hydrogen and oxygen. The image is being released to celebrate Hubble’s 22nd anniversary. The colours come from the glowing hot gas that dominates regions of the image. Notes
Solar System Scope The Measurement of Science Albert Einstein’s greatest scientific “blunder” (his word) came as a sequel to his greatest scientific achievement. That achievement was his theory of gravity, the general theory of relativity, which he introduced in 1915. Two years later, in 1917, Einstein ran into a problem while trying to apply general relativity to the Universe as a whole. At the time, Einstein believed that on large scales the Universe is static and unchanging. Twelve years later, in 1929, Edwin Hubble discovered that the Universe isn’t static and unchanging, but is actually expanding. The story doesn’t end there. The point of the story of the cosmological constant is not that Einstein was a fool. The problem of measuring science Assessing science may be hard, but it’s also something we do constantly. There’s a slightly surreal quality to all this activity. In this essay I argue that heavy reliance on a small number of metrics is bad for science. Three problems with centralized metrics One metric to rule them all
Classification System | The Daffodil Society What do those numbers and letters mean? What are all those number and letter combinations that appear in daffodil catalogues? The Daffodil Society follows the Royal Horticulture Society’s (RHS) daffodil classification system. In 1975, the RHS adopted a colour code system devised by American Dr. The letter refers to the colours of the daffodil as follows: W – White or WhitishG – GreenY – YellowP – PinkO – OrangeR – Red Daffodils are given a colour code to describe both the perianth (petal) colour and the cup colour. See the photo of Kaylee Ann below as an example: All daffodils are classified into one of thirteen divisions.

The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. The earth is in motion. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year. We all learn in grade school that the planets move at differing rates around the sun. Why the huge differences in periods? Johannes Kepler Tycho Brahe Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe. Here you see a planet in a very elliptical orbit.
