Cerf: 2011 will be proving point for 'InterPlanetary Internet' Vint Cerf takes his title of Chief Internet Evangelist for Google seriously. He is knee-deep in several projects to bring the next versions of the Internet into the world -- or in some cases, beyond the world and into the solar system. One of his pet projects includes an extraterrestrial Internet that uses a protocol other than IP. Cerf sat down with Network World's Cisco Subnet editor, Julie Bort, at the annual Digital Broadband Migration conference in Boulder, Colo., to discuss the InterPlanetary Internet, cloud computing standards, the Semantic Web and other topics. PART 1: Cerf: Future of Internet doesn't include an IPv7

Astrophysics Astrophysics People have gazed at the stars, given them names, and observed their changes for thousands of years. NASA joined the ancient pursuit of knowledge of our universe comparatively recently. Goals The science goals of Astrophysics are breathtaking: we seek to understand the universe and our place in it. Wallpaper Videos See the universe come to life via animations, scientific visualizations, expert commentary, and more. 30 Habits Of Highly Effective Teachers Editor’s Note: We often look at the qualities and characteristics of good teaching and learning, including the recent following pieces: How A Good Teacher Becomes Great What You Owe Your Students Ten Secrets To Surviving As A Teacher The Characteristics Of A Highly Effective Learning Environment How To Be A Mediocre Teacher

Great Attractor Panoramic view of the entire near-infrared sky. The location of the Great Attractor is shown following the long blue arrow at bottom-right. The Hubble Telescope turned its lens to the region of the sky where the Great Attractor is located. The Great Attractor is a gravity anomaly in intergalactic space within the range of the Hydra-Centaurus Supercluster that reveals the existence of a localized concentration of mass equivalent to tens of thousands of galaxies, each of which represents the mass of the Milky Way; this mass is observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light-years across. 21 Unbelievable Photographs of Mars Mars is the fourth planet from our Sun in the Solar System. Out of the various planets and moons in our Solar System, Mars perhaps bears the most similarity to Earth, featuring an atmosphere, polar ice caps, and remnants of tectonic activity on the planet’s surface. Mars has fascinated both astronomers and the general public for years, and has been the subject of countless movies and fiction works.

15 Foods That Can Be Regrown From Scraps I love gardening. Well, not actually the work behind the gardening so much – it’s the harvesting that I really look forward to. There is nothing like fresh veggies from your own personal garden! I actually just planted a bunch of things in my vegetable garden, and may have gone a little plant happy at the feed & seed store. Oops. Obviously, we all know about the normal ways to grow plants – from seeds.

The Great Attractor The Question (Submitted September 24, 1999) The great attractor has been described as an agglomeration of matter. What would it look like, a galaxy ? What are its proportions and what are its effects on the Milky Way and other local galaxies. The Answer A Cosmic Exclamation Point VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction. The edge-on galaxy near the top of the image is VV 340 North and the face-on galaxy at the bottom of the image is VV 340 South. Millions of years later these two spirals will merge - much like the Milky Way and Andromeda will likely do billions of years from now.

Chandra est un télescope à rayons X qui été lancé en 1999 par la navette spatiale Columbia. Chandra a profondément transformé notre connaissance de l'univers, nous apportant un nombre considérable d'informations nouvelles ou inattendues. by astro_drillaudweb Jun 28
