MARS glows like a light bulb at Chrismas eve :Except for a fat full moon


Chismas the spritual facts and the Most happiest event of World,,,We see again of the creation of GOD.
Nature will unwrap a heavenly present Christmas Eve: A rare celestial event that for once can be easily seen despite the glare of South Florida's unblinking lights.

Except for a fat full moon, Mars will be the biggest and brightest object in the sky Monday night. It won't be so large or luminous again until 2016, and it won't take as high a path across the sky until 2040.




The red planet outsines the red-nosed reindeer this holiday. Although Rudolph may have a very shiny nose that glows like a light bulb, it's Mars that will glow in the sky on Christmas Eve.

"It's only 55 million miles away, which makes it brighter than the brightest star in the sky on Christmas Eve," said Jack Horkheimer, a Miami Museum of Science and Planetarium astronomer.

The planet Mars will be "at opposition" on Christmas Eve, meaning it will sit directly opposite the sun. It will be about as close and as bright to Earth as it ever gets.

"Plus it will be followed by a spectacular full moon," Horkheimer said. "They will track across the sky together all night long until sunrise Christmas morning."

The two celestial bodies will be highest in the sky at about midnight, which is primetime for Santa Claus. Horkheimer said they'll be so bright that Rudolph won't even be needed to guide St. Nick's sleigh tonight.

"Rudolph can just stay home and chill out at the North Pole this Christmas Eve," Horkheimer said.

So eager viewers who aren't experiencing a foggy Christmas Eve where they live can take a look outside tonight and see the red nose outshined by the red planet.

Israeli scientists inscribe a tiny Jewish Bible



JERUSALEM -- Israeli scientists have inscribed the entire Hebrew text of the Jewish Bible onto a space less than half the size of grain of sugar.

The nanotechnology experts at the Technion institute in Haifa say the text measures less than 0.5 square millimetre surface. They chose the Jewish Bible to highlight how vast quantities of information can be stored in minimum amounts of space.

"It took us about an hour to etch the 300,000 words of the Bible onto a tiny silicon surface,'' Ohad Zohar, the university's scientific adviser for educational programs, told the Associated Press.

The Technion's microscopic Bible was created by blasting tiny particles called gallium ions at an object that then rebounded, causing an etching affect.

"When a particle beam is directed toward a point on the surface, the gold atoms bounce off and expose the silicon layer underneath just like a hammer and chisel,'' Zohar said.

Zohar said the technology will in the future be used as a way to store vast amounts of data on bio-molecules and DNA.

The tiny Bible appears to be the world's smallest.

The previous smallest known copy of the Bible measured 2.8 x 3.4 x 1 centimetres, weighing 11.75 grams and containing 1,514 pages, according to Guinness World Records spokeswoman Amarilis Espinoza. The tiny text, obtained by an Indian professor in November 2001, is believed to have originated in Australia.

Researchers in Israel say they have succeeded in putting a version of the Bible on a chip smaller than a pinhead.
Its 300,000 words in Hebrew were inscribed on a silicon surface at the Haifa Institute of Technology.

Scientists say the aim of the project is to increase young people's interest in nanoscience and nanotechnology.

The record for the smallest copy is held by a Bible measuring 2.8x3.4x1cm (1.1x1.3x0.4in), weighing 11.75g (0.4 ounces) and containing 1,514 pages.

The 0.5sq-mm (0.01sq-in) nano-Bible was written on a silicon surface covered with a thin layer of gold (20nanometres thick - 0.0002mm).

It was written using a device called Focused Ion Beam (Fib).

"When we send the particle beam toward a point on the surface, the gold atoms bounce off of this point, thus exposing the silicon layer underneath," Ohad Zohar, one of the project's managers at Technion, said.

"By sending a particle beam towards various points on the substrate, we can etch any pattern of points, especially one that represents text."

The next step for Technion researchers is photographing the Bible and displaying it on a giant wall within the Faculty of Physics.

"In this picture, which will be 7m by 7m (23ft by 23ft), it will be possible to read the entire Bible with the naked eye (the height of each letter will be some 3mm - 0.1in)," Mr Zohar said.

"Near this picture, the original - the nano-Bible itself, which is the size a grain of sugar - will be displayed."
