Herschel has made over 35 000 scientific observations, amassing more than 25 000 hours’ worth of science data from about 600 observing programmes. A further 2000 hours of calibration observations also contribute to the rich dataset, which is based at ESA’s European Space Astronomy Centre, near Madrid in Spain.
This episode of the ESOcast relates how ESO – based on experience gathered over the past fifty years as the most powerful observatory in history – is going to satisfy the eternal longing of astronomers: the construction of even bigger telescopes.
Google, as many researchers know well, is more than a search engine—it’s a remarkably comprehensive barometer of public opinion and the state of the world at any given time. By using Google Trends, which tracks the frequency particular search terms are entered into Google over time, scientists have found seasonal patterns, for example, in searches for information about mental illnesses and detected a link between searching behavior and a country’s GDP.

Piccard and his partner, André Borschberg, have created one of the strangest flying machines ever–a plane with the wingspan of a jumbo jet, but one that weighs about a ton less than an SUV. Its power is generated by nearly 12,000 silicon solar cells over the main wing and the horizontal stabilizer that charge lithium-polymer battery packs contained in the four gondolas under the wing. The batteries in total weigh almost 900 pounds–that’s about one quarter of the plane’s weight–and they’re capable of storing enough energy to allow the plane to fly at night.
Wool&Prince claim they have invented a shirt that stays clean even after 100 days of wear, made from wool which is also wrinkle free.
This is one of ATV-5′s solar panels as it will fly in space. It is not necessary to protect the cables other than fixing them in a wavy line to withstand physical stress during launch and deployment.
As machines take on more jobs, many find themselves out of work or with raises indefinitely postponed. Is this the end of growth? No, says Erik Brynjolfsson — it’s simply the growing pains of a radically reorganized economy. A riveting case for why big innovations are ahead of us … if we think of computers as our teammates. Be sure to watch the opposing viewpoint from Robert Gordon.
Tech columnist David Pogue shares 10 simple, clever tips for computer, web, smartphone and camera users. And yes, you may know a few of these already — but there’s probably at least one you don’t.
International Space Station Commander Chris Hadfield “lifts the lid” on the Water Recovery System, the first liquid recycling system to be flown in space that cleans almost all the “water” (greywater, urine, sweat) produced by crew members so that it can be used again. As previous space station resident Don Pettit has said, “Yesterday’s coffee becomes today’s coffee.”
What causes a Tornado to form? How can we foresee them? New technologies are giving people more and more time to prepare and seek shelter in a time of crisis, whether it be from information gathered on the ground or spectacular visual mapping from new satellites in space. Engineer and storm chaser Tim Samaras gives his unique perspective and insight on the situation.
Your breath says a lot about you. Recent research has found that the chemicals present in each person’s breath can provide a unique “breathprint” that differs from person to person, while other scientists have worked on breathalyzer-like tests that can indicate the presence of a bacterial infection inside someone’s body.
When you sit back and think about how far away exoplanets are — and how faint — it’s a scientific feat that we can find these distant worlds outside our Solar System at all. It’s even harder to learn about the world if the exoplanet is orbiting a dim star — say, about two-thirds the size of the Sun — that is faint through even the largest telescope.
Oops! Nobody wants to see the 404: Page Not Found. But as Renny Gleeson shows us, while he runs through a slideshow of creative and funny 404 pages, every error is really a chance to build a better relationship.
