Universe is Not Expanding After All, Scientists Say New evidence, based on detailed measurements of the size and brightness of hundreds of galaxies, indicates that the Universe is not expanding after all, says a team of astrophysicists led by Eric Lerner from Lawrenceville Plasma Physics. This image shows a star forming region in a nearby galaxy known as the Large Magellanic Cloud. Image credit: ESA / Hubble. In their study, the scientists tested one of the striking predictions of the Big Bang theory – that ordinary geometry does not work at great distances. In the space around us, on Earth, in the Solar System and our Milky Way Galaxy, as similar objects get farther away, they look fainter and smaller. In contrast, the Big Bang theory tells us that in an expanding Universe objects actually should appear fainter but bigger. So in an expanding Universe the most distant galaxies should have hundreds of times dimmer surface brightness than similar nearby galaxies, making them actually undetectable with present-day telescopes.

untitled L'ordinateur quantique ThierryLombry Informaticien Depuis l'invention du premier circuit intégré monolithique par Jack Kilby de Texas Instruments en 1958, l'intégration des composants électroniques n'a cessé d'être améliorée au point que nous parvenons aujourd'hui à faire fonctionner des centaines de milliers de composants sur une puce (chip) mesurant à peine 1 cm2, c'est la technologie ULSI (Ultra Large Scale Integration) qui détrône aujourd'hui le VLSI. Le coeur de l'ordinateur : le microprocesseur Mais à cette échelle la difficulté de fabrication devient digne d'une mission impossible.

The Universe Magnified This is one of the most beautiful infographics we've ever seen: a high resolution view of different levels of the universe. Our favorite parts are the jaw-dropping nebulae and then the point where you see the size of Pluto compared to Texas. Puts things into perspective. Try it out in full-screen mode: Copyright 2012.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. i i i
How to Process Your Own Colour Images from Hubble Data The Hubble Space Telescope uses a number of different filters when taking images of objects. The best wideband filters for the production of colour images are F435W, F439W, F450W, F555W, F606W, F675W, F702W, F791W, and F814W. Narrowband filters used include F437N, F502N, F656N, F658N, and F673N. 1Locate the fourth image in the result for the search of NGC 604 above and you will find the file name "hst_05237_02_wfpc2_f814w_wf" below it. For this guide, download hst_05237_02_wfpc2_f814w_wf, hst_05237_02_wfpc2_f555w_wf, and hst_05237_02_wfpc2_f336w_wf.

More sensitive, faster, wider spectrum, more sky coverage The Breakthrough Listen initiative will be 50 times more sensitive than previous programs dedicated to SETI research, the scientists say.
