The Celestia Motherlode: Earth Surface Maps Surface Maps | Bump, Normal, Spec Maps | Cloud Maps | Night Maps | Close-ups | Other Earth Files This page contains surface textures for the planet Earth. Most textures here are based on data from the NASA project Blue Marble, but have been modified in various ways to enhance colors etc. The original Blue Marble data had a resolution of 42K (43200x21600), but the improved dataset "Blue Marble Next Generation" was made available in 2005, offering a resolution of 86400x43200 and better quality in many details. Note that a 64K texture made from the original dataset has less detail than one made from the "Next Generation" dataset. Note that "(pre)shaded" refers to textures which have a static shadow already visible on the surface. Generally this looks better than a flat surface texture, but shadows may appear at the wrong side of a mountain because shadows don't follow changes to the sun's position.

The McGill University Centre for Research in Air and Space Law is the principal research and educational outreach arm of McGill’s Institute of Air and Space Law, established in 1951.

NIGHTSCAPE – Craft & Vision David Kingham expertly explains every aspect of this style of photography as he covers topics like: stars, constellations, meteors, moon phases, galaxies, scouting, gear, field work, shooting technique and post-processing. Nightscape is an in-depth resource full of detailed descriptions, charts, maps, and step-by-step actions, practical insights and beautiful photographs that will inspire you to get outside. BONUS: Also included within this eBook (on Page 88) is a download link to 22 Lightroom presets. It's important to note that we recommend Adobe Acrobat for PDF viewing and for selecting Resource hyperlinks; applications such as Mac Preview don't always play nice. One Sad Monkey » Carl Sagan What lady could resist my turtleneck? I was listening to the love story between Carl Sagan and his third and final wife Anne Druyan from an episode in Radiolab. I kept playing it again and again because there this gigantic gap in the story that seems to require a giant cognitive leap that I just couldn’t make. Carl was on his second marriage with his wife Linda Salzman with which he had a child with. Anne Druyan was in a serious relationship with a man and the two couples were friends.

Millennium Simulation Project Introduction: The Millennium Simulation The Millennium Run used more than 10 billion particles to trace the evolution of the matter distribution in a cubic region of the Universe over 2 billion light-years on a side. It kept busy the principal supercomputer at the Max Planck Society's Supercomputing Centre in Garching, Germany for more than a month. Mapping The Universe A new map of our complex universe is out. We’ll look at our “chunky” cosmos. We look up at the night sky and marvel at its depth and beauty. Its constellations and its stupendous scale. And then on a curious night we wonder, what is all that? What shape, what age, what stuff?

Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does. Now let me be clear: this is a planet candidate; it has not yet been confirmed.

Jay Alfred - Acupuncture Meridians & the Cosmic Spider Web Posted on Friday, 2 March, 2007 | 1 comment Columnist: Jay Alfred In 1999 computer simulations of magnetic fields in galaxy clusters by Klaus Dolag revealed that galaxy clusters are embedded in a large-scale spider-web-like structure of filaments. Star Walk - Interactive Astronomy Guide Stargazing guide Enjoy Stars Day or Night Now on Apple Watch! Star Walk is an interactive astronomy guide that shows celestial objects in the exact positions on the sky above you, providing detailed information about them. It helps anyone even remotely interested in astronomy find their way across the sky, determine where to look for any object, rewind or fast-forward time to see how celestial bodies move.

The Five Great Problems in Theoretical Physics - Lee Smolin's Five Great Problems in Theoretical Physics In his controversial 2006 book The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next, theoretical physicist Lee Smolin points out "five great problems in theoretical physics." The problem of quantum gravity: Combine general relativity and quantum theory into a single theory that can claim to be the complete theory of nature. The foundational problems of quantum mechanics: Resolve the problems in the foundations of quantum mechanics, either by making sense of the theory as it stands or by inventing a new theory that does make sense.
