Solar System Scope "ET Technology Could Appear as Natural Objects in the Universe" According to the British physicist Stephen Wolfram, intelligent life is inevitable. But there is a hitch. Although intelligent life is inevitable, we will never find it -at least not by looking out in the Milky Way. As evidence Wolfram points out In order to compress more and more information into our communication signals - be they mobile phone conversations or computer- we remove all redundancy or pattern. If anything in a signal repeats, then clearly it can be excised. According to Wolfram, if someone beamed our own 21st-century communication signals at us from space we would be hard pressed determining whether they were artificial or natural. ET artifacts coordinated by computers would look far more like a natural onject. If Wolfram is right and ETs are out there but we will not be able to recognize them - either in their communications or their artifacts - then of course they could be here in the Solar System and we would not have noticed.

The above is an interactive infographic. We have also developed a complimentary poster that you can view here: Sizes of the Universe poster. If you're technically inclined, here's a look at the references we used to construct these infographics: Facts About The Universe. 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. How To Use: Credits:
If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
Your Age on Other Worlds Want to melt those years away? Travel to an outer planet! <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your birthdate below in the space indicated. (Note you must enter the year as a 4-digit number!) 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. Kepler's third law is the one that interests us the most. Let's just solve for the period by taking the square root of both sides: Isaac Newton
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. 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. To make a sky map, enter the latitude and longitude of your observing site in the boxes below (be sure to check the correct “North/South” and “East/West” settings) and press the “Make Sky Map” button below the form. 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 On the Web:
The Milky Way Project The very first image of a black hole, explained by 2 astrophysicists This week, a group of scientists unveiled the first-ever image of a black hole at the center of the Messier 87 galaxy, some 55 million light-years away. The image comes to us from a vast and incredibly sophisticated scientific collaboration called the Event Horizon Telescope, which involves 200 scientists in 20 countries who’ve been working together for nearly a decade. The image they created has been eagerly anticipated by all those enthralled by black holes, and it does not disappoint: a deep black well in the center of a bright ring of plasma and gas. Some may not be impressed by the slight blurriness of the image. But there’s so much more to it than what immediately meets the eye. Two astrophysicists — Sheperd Doeleman, the project leader of the Event Horizon Telescope, and Katie Mack of North Carolina State University, who was not involved with the effort — walked me through a few of the coolest aspects of the image that helped me appreciate just wonderfully mind-blowing it is.
SpaceWander Virtual Space Trip! Schrodinger's 'Kitten'? Large-Scale Quantum Entanglement Achieved By Two Physics Labs Uncategorized Published on July 26th, 2013 | by Michael Ricciardi July 26th, 2013 by Michael Ricciardi In the famous gedanken experiment posited by famed quantum physicist Erwin Schrodinger in the 1930′s, a hypothetical cat resides in a closed box with a radioactive atom which may exist in a stable or decaying state; if the atom decays, it triggers the release of a poison contained in a flask, which would kill the poor, putative puttycat. The opening of the box is an analogy for performing a measurement on the quantum system. Such a superposition of quantum states — like another bizarre quantum property known as entanglement in which the states of two quantum particles are linked regardless of the distance between them — apply to exceedingly tiny objects; they do not (according to Schrodinger and many modern physicists) apply to everyday objects in the macro world that we can see and touch. For many physicist, the idea of applying this quantum effect to larger scale systems is absurd.
Across Our Blogs: Mars Curiosity Rover Moonrise, New Rover, Billion Pixel Marsscape Seems the Mars Curiosity Rover has been a busy little six-wheeled fellow these past few weeks. Here's a roundup of news related to the rover, from top Technorati listed science blogs...
