Mother Earth, The Sun is Not Your Father…

After much number crunching and analysis NASA boffins have announced the Sun is not our Father.

Data returned by NASA’s Genesis space craft and analyzed around the world suggests that Sun and Earth were formed separately. Like a giant paternity test scientists studied matter collected from the oldest part of the Sun and compared it to samples from the Earth. Sorry Sun you ARE NOT the Father, time for some more tests.

“We found that Earth, the moon, as well as Martian and other meteorites which are samples of asteroids, have a lower concentration of the O-16 than does the sun,” said Kevin McKeegan, “The implication is that we did not form out of the same solar nebula materials that created the sun — just how and why remains to be discovered.”

The Artificial Leaf on Silicon Trees…

Scientists at MIT have demonstrated the first practical artificial leaf.

This doesn’t mean the oak tree out the front of your house should be worried, these leaves will never hang from a branch. Nor do they look like a leaf, with a silicon cell immersed in a cylinder of bubbling water they are more laboratory ready than they are garden ready.

Instead of simply using the solar cell to produce electricity the cells use a special coating on the silicon, along with the power from the cell to split the water into its hydrogen and oxygen components.

Being able to directly convert water and sunlight into storable gas provides solutions to the biggest problems with solar power, no light no power. At night the gas could be fed to a fuel cell to convert the gases back into electricity and water. The holy grail of renewable power just got one step closer.

Solar Flare Cycle MIA, Solar Slumber…

Ever since the first caveman was forced to get out of bed early the Sun’s cycles have been of studied with interest. From the timings of our daily lives to the coming of Santa each year the Sun’s timing permeates every part of our lives.

Scientists recently met to discuss the 11 year solar flare cycle. Meeting in New Mexico for the American Astronomical SocietyAAS – Solar Physics Conference, 320 scientists gathered to compare notes, share information and generally schmooze about the Sun.

Tuesday – 14.06.2011 – the scientist announced their findings and predictions for the next solar cycle. It looks like jumpers and scarfs are in and speedos are out, solar flare activity between 2013 and 2024 may be almost completely absent. The impact of this sustained level of low solar flare activity is still being debated with effects ranging from another mini ice-age, slight mitigation of global warming to some that expect zero impact on the Earths weather.

Quantum Vacuum Fluctuations, Zero Point Energy and the Mirror of Gothenburg…

In the depths of Deep Space, the vast emptiness may be more alive than we ever thought possible.

The vacuum of space isn’t as void as previously advertised. Zero-Point EnergyZPE – pervades every corner of the universe, populating space with it’s minimalism. This week a new experiment was conducted that went a long way to confirming the existence of Zero Point Energy.

Scientists at the Chalmers University of Technology in Gothenburg, Sweden constructed an electronic magnetic mirror and wiggled it 6 billion times a second. At this speed the mirror was able to produce a shower of photons from nothing, reflect light that wasn’t even there. In a completely dark and void vacuum, zero-point energy it seems exists.

Deep Space Voyager…

In the cold dark recesses of space a single mission carries the torch for humanity. Voyager 1 and 2 are soon to leave the solar system completely, entering deep space with its sensors being our eye’s and ears. Will they be required to stay left unless overtaking on some inter-galactic super highway ? That’s the adventure, we don’t know. The Voyager space craft have a history of surprising us, a tradition that will continue as long as the batteries hold up.

“They are about to break free of the solar system,” Ed Stone, Voyager project scientist at Caltech in Pasadena, Calif., said during a media teleconference (April 28). “We are trying to get outside of our bubble, into interstellar space, to directly measure what is there.”

The Voyager craft have reached the outer border of our solar system, the heliosphere. The heliosphere is the border-land between our solar system and deep space, like the shiny surface of a bubble. The heliosphere marks the end of the Sun’s sphere of influence, it is where the solar winds run out of steam and the furthest point of the magnetic field. Voyager 1 passed the first layer of the heliosphere, the termination shock and entered the heliosheath in the middle of December 2004.

Metalic Glass…

Metallic Glasses, the new wonder material for a world pushing the boundaries. When Titanium is no longer strong enough where do you turn, BMGBulk Metallic Glasses – 2.5 times stronger than titanium, but with the production costs of plastic. Cheap tough and very quick to form. Could metallic glass marbles be the toy of the future ?

First discovered by Klement, Willens and Duwez at CalTech – Californian Institute of Technology – in 1960’s . Production of Metal Glass wouldn’t occur until the early 90’s when William L. Johnson and his team were able to develop a commercially viable process. Liquidmetal Technologies was incorporated as a company in 2003 to manage the patents and products including Vitreloy, the first commercially available Metallic Glass.

The Loneliest Planets…

Scientists have recently confirmed the existence of large number of free-floating planets, planets not part of any particular solar system. These are the Loneliest Planets of all.

Destined to roam the universe bumping along with no particular destination in mind and no traveling companions. Traditionally scientific belief has held that most planets orbited the sun they were formed around. A study has recently revealed – published in the scientific journal Nature – the possibility of 400 billion free-floating planets in the Milky Way.

This raises many questions, how were these planets formed and can we explain all of these planets with current theory. What happens to planets in their life time ? This is one of those interesting new discoveries that makes us reconsider what we take for granted. “This is an amazing result, and if it’s right, the implications for planet formation are profound,” says astronomer Debra Fischer at Yale University in New Haven, Connecticut.
