Photographer Revisits Underwater Paradise
National Geographic photographer David Doubilet explores the glittering world hidden beneath the waves of Papua New Guinea’s Kimbe Bay. After shooting a photo assignment there 17 years ago, he was eager to return.

Five Years of Great Discoveries for NASA’s IBEX
Launched on Oct. 19, 2008, the Interstellar Boundary Explorer, or IBEX, spacecraft, is unique to NASA’s heliophysics fleet: it images the outer boundary of the heliosphere, a boundary at the furthest edges of the solar system, far past the planets, some 8 million miles away. There, the constant stream of solar particles flowing off the sun, the solar wind, pushes up against the interstellar material flowing in from the local galactic neighborhood. IBEX is also different because it creates images from particles instead of light. IBEX, scientists create maps from the observed neutral atoms. Some are of non-solar origin, others were created by collisions of solar wind particles with other neutral atoms far from the sun. Observing where these energetic neutral atoms, or ENAs, come from describes what’s going on in these distant regions. Over the course of six months and many orbits around Earth, IBEX can paint a picture of the entire sky in ENAs.
During its first five years, IBEX has made some astounding discoveries.
IBEX is a NASA Heliophysics Small Explorer mission. The Southwest Research Institute in San Antonio, Texas, leads IBEX with teams of national and international partners. NASA’s Goddard Space Flight Center in Greenbelt, Md., manages the Explorers Program for the agency’s Science Mission Directorate in Washington.

Master of Disguise: The incredible camouflage of a weedy scorpionfish
Led by a school of blue-banded snapper, the Earth Touch crew dive to the bottom of Stringer Reef off the coast of South Africa to investigate the area’s underwater life. After spending some time with a well-camouflaged paperfish, the crew encounters an even more impressive master of disguise: the weedy scorpionfish. It’s the first time in a decade of diving that cameraman Grant Brokensha has spotted one of these unique creatures and it’s not hard to see why!

Astronaut Uses Single Hair To Show Newton’s Laws
On-orbit astronaut Karen Nyberg proves Cady Coleman told ‘Gravity’s Sandra Bullock the truth: a single strand of human hair pushed against a handrail aboard the ISS sprang Nyberg backwards in microgravity.

Gregg Treinish: Adventures in Conservation
Many outdoor enthusiasts live to pursue sports in far-flung regions. Many scientists need samples and data from those same hard-to-reach places. Enter National Geographic Emerging Explorer and conservationist Gregg Treinish, who’s bringing the two worlds together in the name of science.
Hunting Extraterrestrials: Interview with SETI Icon Jill Tarter
The Search for Extraterrestrial Intelligence. No other space-related program so effectively stirs our emotions, symbolizes our sense of hope and optimism for the future, or provokes philosophical debates about the meaning of our life and our place in the universe. Dr. Jill Tarter, a key player and icon of SETI, the Search for Extraterrestrial Intelligence, joins Justin Trottier for a special live interview of The Star Spot, an astronomy and space themed podcast, filmed as part of the Centre for Inquiry’s Fall Equinox events.
Astronomer Jill Tarter is the holder of the Bernard M. Oliver Chair for SETI. She is one of the few researchers to have devoted her career to hunting for signs of sentient beings, and there are few aspects of this field that have not been affected by her work.
Jill was the lead for Project Phoenix, a decade-long SETI scrutiny of about 750 nearby star systems, using telescopes in Australia, West Virginia and Puerto Rico. While no clearly extraterrestrial signal was found, this was the most comprehensive targeted search for artificially generated cosmic signals ever undertaken. Now Jill heads up the Institute’s efforts to build and operate the Allen Telescope Array, a massive new instrument that will eventually comprise 350 antennas, each 6 meters in diameter. This telescope will be able to enormously increase the speed, and the spectral search range, of the Institute’s hunt for signals. A subset of the full array will begin operations in the Fall of 2007.
Indeed, being as much of an icon of SETI as Jill is, perhaps it is not surprising that the Jodie Foster character in the movie “Contact” is largely based on this real-life researcher.

James May Q&A - How do spacesuits work?
You’ve seen the videos of those astronauts on the International Space Station getting suited and booted in a spacesuit before a spacewalk, but how exactly does the space suit work?
A spacesuit has to protect you from the glaring radiation from the sun as well as keeping you warm from the extreme cold of outer space. As well as that is has to make sure you have enough oxygen and enough movement so you can actually do your job.
It also has to be pressurised to about 4.7PSI. Otherwise the empty vacuum of outer space will make your organs increase to twice their normal size and you will meet a very unpleasant untimely death.

Planck’s view of the Universe
This animation highlights some of the many discoveries made by ESA’s Planck space telescope over its 4.5 year observing career, from new discoveries in our home Milky Way Galaxy stretching back to the first few moments after the Big Bang 13.82 billion years ago.

Rosetta’s twelve-year journey in space
This animation tracks Rosetta’s journey through the Solar System, using gravity slingshots from Earth and Mars to reach its final destination: Comet 67P/Churyumov—Gerasimenko. Rosetta made three flybys of Earth, on 4 March 2005, 13 November 2007 and 13 November 2009, and one of Mars, on 25 February 2007. Rosetta has also visited two asteroids, taking extensive close-up images of 2867 Steins on 5 September 2008 and 21 Lutetia on 10 July 2010. Once the spacecraft is woken up from deep space hibernation on 20 January 2014, it will head for rendezvous with the comet in May. In November the Philae probe will be deployed to the comet surface. Rosetta will follow the comet to its closest distance to the Sun on 13 August 2015 and as it moves back towards the outer Solar System. The nominal mission end is December 2015.
GPS technology - Mapping lakes in Norway
Jonas just got back from Norway where he spent the summer living in a camper van while helping out on a project mapping out the bottom of mountain lakes. Here is a short video explaining the project. Beautiful country, with incredible scenery but don’t let the images of good weather fool you. The first week they actually had non-stop rain while literally living in a cloud at about 1000m altitude. Everything was soaking wet for the whole week and the heater broke. Still awesome though.
