I found a great gallery of images showing stuff at all scales, from “Quarks to Quasars”.

Excerpt from 10²¹: Given an estimated age for our solar system of 4.5 thousand million years, the Sun has made about 15 to 18 orbits around the galactic core.

Bruce Bryson writes: “This is a visual journey consisting of 42 images — 42 powers of ten. At one end of the journey is the immensity of the known universe, 13.7 billion years old with a radius of at least 12 billion light years (and probably much larger). At the other end of the journey is a depiction of the three quarks within a proton.”

ESA’s Envisat The most detailed portrait ever of the Earth’s land surface is being created with ESA’s Envisat environmental satellite. The GLOBCOVER project aims at producing a global land cover map to a resolution three times sharper than any previous satellite map.

It will be a unique depiction of the face of our planet in 2005, broken down into more than 20 separate land cover classes. The completed GLOBCOVER map will have numerous uses, including plotting worldwide land use trends, studying natural and managed ecosystems and modelling climate change extent and impacts.

Envisat’s Medium Resolution Imaging Spectrometer (MERIS) instrument is being systematically used in Full Resolution Mode for the project, acquiring images with a spatial resolution of 300 metres, with an average 150 minutes of acquisitions occurring daily.

[/.] PunkOfLinux writes “TechWeb has an article about Google’s plans to start a video service that sounds similar to Picasa. Excerpt: ‘While there’s no formal announcement yet, Google co-founder Larry Page said Monday that the well-known search engine concern would soon let the general public upload self-produced videos to Google’s servers, partly in an effort to learn more about how to more efficiently search and display information about video-based data.’”
