Nanobama

The nanobama structures are made of carbon nanotubes, and the pictures were taken using optical and electron microscopes. Carbon nanotubes (CNTs) are tiny hollow cylinders of carbon; the diameter of a CNT is tens of thousands of times smaller than a human hair, and CNTs are several times stronger and stiffer than steel.

How they are made? Check it out: Nanobama

Nature Unleashed: Inside Natural Disasters

Nature Unleashed investigates what we know and are still learning about nature’s terrifying power by focusing on four types of disasters—earthquakes, volcanoes, hurricanes, and tornadoes. These phenomena are the spectacular results of forces that drive our ever-changing planet and dramatically affect the lives of everyone around the world. From Pompeii to Papua New Guinea, from New Orleans to Greenburg, Kansas, Nature Unleashed examines the science behind the history and the headlines.

To understand how natural phenomena work, interactive displays and animations let you trigger an earthquake, simulate a tsunami, generate a virtual volcano, and stand within the center of a roaring tornado. Images, artifacts, and inspiring survivor stories then bring home the realities of recent disasters by revealing how people adapt to living at risk.

NASA Images

This stunning false-color picture shows off the many sides of the supernova remnant Cassiopeia A. It is made up of images taken by three of NASA's Great Observatories, using three different wavebands of light. Infrared data from the Spitzer Space Telescope are colored red; visible data from the Hubble Space Telescope are yellow; and X-ray data from the Chandra X-ray Observatory are green and blue. Located 10,000 light-years away in the northern constellation Cassiopeia, Cassiopeia A is the remnant of a once massive star that died in a violent supernova explosion 325 years ago.

NASA Images is a new comprehensive database of NASA images to increase our understanding of the earth, our solar system and the universe beyond in order to benefit humanity. Highly recommended!

Explore the International Space Station

The ISS Interactive Reference Guide is a fun way to learn about, and explore the space station to achieve a better understanding of how it operates, and generally what it is. This interactive feature includes:

  • How the crew lives: how they eat, sleep, and exercise
  • How the ISS: is operated, built, and supported
  • A 360 degree view of the space station
  • An explanation of the ISS's purpose
  • And a cool music video!

Cosmic Voyage

A sweeping view of the universe!

This 36 minutes short documentary takes you on a journey through forty-two orders of magnitude, beginning at a celebration in Italy to zoom to the outer limit of human visibility. The view descends back to earth, and later zooms in upon a raindrop on a leaf, to the level of sub-atomic particles. Cosmic Voyage, narrated by Morgan Freeman, is truly fascinating with great graphics.




Enjoy your weekend!

Galaxies Gone Wild

image


Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies.

A series of 59 new images of colliding galaxies has been released from the several terabytes of archived raw images from the NASA/ESA Hubble Space Telescope to mark the 18th anniversary on 24th April 2008 of the telescope’s launch.

This is the largest collection of Hubble images ever released to the public simultaneously.

The Complete Work of Charles Darwin Online

I saw this in our newspaper last weekend: Darwin's private papers online for all to see - and it's kept me busy for a while.

In October 2006 [link BBC article], Cambridge University decided to put the complete works of Charles Darwin online, and it seems that now the project has evolved, to include his private papers too.

After making the original draft of Darwin’s "On The Origin Of Species", some 20,000 other writings and 90,000 images available to the public now.

The collection includes thousands of notes and drafts of his scientific writings, notes from the voyage of the Beagle when he began to formulate his controversial theory of evolution, and his first recorded doubts about the permanence of species.

It also contains photographs of Darwin and his family, newspaper clippings, reviews of his books and much more.

The Complete Work of Charles Darwin Online

For a basic, non-academic, entryway go here: The major works of Charles Darwin Near the bottom of this page you will find all the the thousands illustrations available.

Some other highlights:

Ocean Explorer

Porpita porpita has a small disc like body and floats freely in the water column. Related to the jellyfish, this species measures just one inch in diameter:


image


The picture above you'll find at Ocean Explorer Gallery: Living Ocean, with hundreds of images and videos of the living ocean.

NOAA Ocean Explorer is an educational Internet offering for all who wish to learn about, discover, and virtually explore the ocean realm. It provides public access to current information on a series of NOAA scientific and educational explorations and activities in the marine environment. The site provides a platform to follow explorations in near real-time, learn about exploration technologies, observe remote marine flora and fauna in the colorful multimedia gallery, read about NOAA's 200-year history of ocean exploration, and discover additional NOAA resources in a virtual library.

NOAA Ocean Explorer - be warned, this is an enormous site!!!

They have also a YouTube channel.

Space Debris: Evolution In Pictures

Between the launch of Sputnik on 4 October 1957 and 1 January 2008, approximately 4600 launches have placed some 6000 satellites into orbit, of which about 400 are travelling beyond geostationary orbit or on interplanetary trajectories.

Today, it is estimated that only 800 satellites are operational - roughly 45 percent of these are both in LEO and GEO. Space debris comprise the ever-increasing amount of inactive space hardware in orbit around the Earth as well as fragments of spacecraft that have broken up, exploded or otherwise become abandoned. About 50 percent of all trackable objects are due to in-orbit explosion events (about 200) or collision events (less than 10).

Origins of AIDS

While AIDS may be one of the most feared diseases of modern times, there is still a degree of scientific debate over the subject of just how the disease originated, and how the first cases spread. Two filmmakers explore a controversial theory about the beginnings of the disease. In the 1950s, American and Belgian missionaries in the Belgian colonies of the Congo widely distributed polio vaccine to a million children in a bid to wipe out the crippling disease; however, evidence now suggests that Dr. Koprowski's oral vaccine may have been tainted, and that the first instances of the disease may be linked to these inoculations. Using interviews, newsreel footage, and documented research experiments, "The Origin of AIDS" examines how a combination of benevolence, careless lab procedures, and the need of a desperate few to cover their tracks could have led to one of the most serious pandemics of the 20th century.

Extreme Engineering: Transatlantic Tunnel

A transatlantic tunnel is a theoretical tunnel which would span the Atlantic Ocean between North America and Europe and would carry mass transit of some type—trains are envisioned in most proposals. Using advanced technologies, speeds of 300 to 5,000 mph (500 to 8,000 km/h) are envisioned.

Plans for such a tunnel have not progressed beyond the conceptual stage, and no one is actively pursuing such a project. The main barriers to constructing such a tunnel are cost - as much as $12 trillion.

So, if you could take the train from New York and in less than an hour reach London, would you do it? What if you had to make the journey through a tunnel 150 feet under the Atlantic? And on a magnetically levitated train traveling at 5,000 mph?

In 2003, the Discovery Channel's show 'Extreme Engineering' aired a program entitled 'Transatlantic Tunnel' which discusses the proposed tunnel concept in detail.

See also Discovery Channel's Extreme Engineering: Transatlantic Tunnel interactive tour.

Watch today Extreme Engineering: Transatlantic Tunnel (2003).
Duration: 44 minutes.
