Little Bang Most Likely Triggered Solar System Formation

For several decades, scientists have thought that the Solar System formed as a result of a shock wave from an exploding star — a supernova — that triggered the collapse of a dense, dusty gas cloud that contracted to form the Sun and the planets. But detailed models of this formation process have only worked under the simplifying assumption that the temperatures during the violent events remained constant. Now, astrophysicists at the Carnegie Institution's Department of Terrestrial Magnetism (DTM) have shown for the first time that a supernova could indeed have triggered the Solar System's formation under the more likely conditions of rapid heating and cooling. The results, published in the October 20, 2008, issue of the Astrophysical Journal, have resolved this long-standing debate.

New Eye on the Outer Solar System Launches Successfully

There's a new spacecraft in Earth orbit, with a really "far out" mission: to map the outer solar system. NASA's Interstellar Boundary Explorer mission, or IBEX launched successfully from the Kwajalein Atoll in the Pacific Ocean at 1:47 p.m. EDT, Sunday, from an Orbital Sciences Pegasus XL launch vehicle. IBEX will be the first spacecraft to image and map dynamic interactions taking place in the outer solar system. The two Voyager probes sent back a limited amount of information about the region of space where our solar system ends and interstellar space begins. But beyond that, not much is known about this area. The region is about three times further from the sun than the orbit of planet Pluto. "No one has seen an image of the interaction at the edge of our solar system where the solar wind collides with interstellar space," said IBEX Pr

Our Solar System Born in 'Little Bang'

First there was the theoretical Big Bang that got the universe going. Several billion years passed. Then a Little Bang birthed our solar system.

7th-Grader Designs Three Dimensional Solar Cell

Hugh Pickens writes "12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. 'Current solar cells are flat and can only absorb visible light'" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency.' Solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells.

Portable Solar Power For Portable Hardware?

Tjeerd writes "Because the 'green revolution' is accelerating, I felt it was time to get involved. Last week I started with buying a portable solar energy charger for my mobile phone. But soon I was thinking of also recharging my Asus Eee netbook with a portable solar energy recharger. I found things like the Portable Power Pack, Foldable Solar Chargers, and the Solar Gorilla. The Solar Gorilla looks quite interesting and might be able to recharge my netbook and fits nicely in a rucksack. But I would like some real-life feedback. If you have experience with these or other portable solar devices, what has worked for you?"

West Basin's Solar Powered System Produces More Power, Performs Beyond Expectation in First Year

West Basin Municipal Water District's 60,000 square feet of fixed-tilt photovoltaic panels at the Edward C. Little Water Recycling Facility is performing beyond expectations. In the first year of operation, the system produced 11% more electricity than expected. Based on capacity output and solar power area in place, the system was estimated to produce 814,199 kW of electricity and actually provided 903,800 kW for its first year of operation (January to December 2007). This power generation represented an annual power cost savings of $90,000.00.

First fuzzy photos of planets outside solar system

Earth seems to have its first fuzzy photos of alien planets outside our solar system, images captured by two teams of astronomers. The pictures show four likely planets that appear as specks of white, nearly indecipherable except to the most eagle-eyed experts. All are trillions of miles away — three of them orbiting the same star, and the fourth circling a different star.

New Solar Cell Sets World Efficiency Record

asoduk writes to tell us that a new world record has been set for the most efficient photovoltaic device. Topping the scale at 40.8% efficiency, the new solar cell differs significantly from the previous record holder. "Instead of using a germanium wafer as the bottom junction of the device, the new design uses compositions of gallium indium phosphide and gallium indium arsenide to split the solar spectrum into three equal parts that are absorbed by each of the cell's three junctions for higher potential efficiencies. This is accomplished by growing the solar cell on a gallium arsenide wafer, flipping it over, then removing the wafer. The resulting device is extremely thin and light and represents a new class of solar cells with advantages in performance, design, operation and cost.

Earth's 10 Most Impressive Impact Craters

Ever since our recent encounter with asteroid 2008 TC3 — the first asteroid that was correctly predicted to hit our planet — I've had impact craters on the brain. Earth has about 175 known impact craters, but surely our planet has endured more bashing than that in its history. All the other terrestrial planets and moons in our solar system are covered by impact craters. Just look at our Moon through a telescope or binoculars, or check out the recent images of Mercury sent back by the MESSENGER spacecraft, or pictures of Mars from the armada of spacecraft orbiting the Red Planet, and you'll see that impact craters are the most common landforms in our solar system. But since two-thirds of Earth is covered by water, any asteroid impacts occurring in the oceans are difficult to find.

Solar system's young twin has two asteroid belts

Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three rings of material implies that unseen planets confine and shape them.
