please put a cool message in here about world peace
it is an archealogical record... and your name
just in case
say who you are
I signed my name.

Given Saturn’s diameter of about 120,000 km (72,000 miles) and the latitude of the storm (call it 45°), this monster system must be well over 300,000 km (180,000 miles) in length! That’s three-quarters of the way from the Earth to the Moon. ... Note that just the north/south extent of the storm is roughly the size of Earth.

this is cool
Diamond star thrills astronomers
A diamond that is almost forever Twinkling in the sky is a diamond star of 10 billion trillion trillion carats, astronomers have discovered. The cosmic diamond is a chunk of crystallised carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus.
It's the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk.
Astronomers have decided to call the star "Lucy" after the Beatles song, Lucy in the Sky with Diamonds.
Twinkle twinkle
"You would need a jeweller's loupe the size of the Sun to grade this diamond," says astronomer Travis Metcalfe, of the Harvard-Smithsonian Center for Astrophysics, who led the team of researchers that discovered it.
The diamond star completely outclasses the largest diamond on Earth, the 546-carat Golden Jubilee which was cut from a stone brought out of the Premier mine in South Africa.
The huge cosmic diamond - technically known as BPM 37093 - is actually a crystallised white dwarf. A white dwarf is the hot core of a star, left over after the star uses up its nuclear fuel and dies. It is made mostly of carbon.
For more than four decades, astronomers have thought that the interiors of white dwarfs crystallised, but obtaining direct evidence became possible only recently.
The white dwarf is not only radiant but also rings like a gigantic gong, undergoing constant pulsations.
"By measuring those pulsations, we were able to study the hidden interior of the white dwarf, just like seismograph measurements of earthquakes allow geologists to study the interior of the Earth.
"We figured out that the carbon interior of this white dwarf has solidified to form the galaxy's largest diamond," says Metcalfe.
Astronomers expect our Sun will become a white dwarf when it dies 5 billion years from now. Some two billion years after that, the Sun's ember core will crystallise as well, leaving a giant diamond in the centre of the solar system.
"Our Sun will become a diamond that truly is forever," says Metcalfe.
GENEVA (AP) -- Scientists at the world's largest physics lab say they have clocked subatomic particles traveling faster than light, a feat that - if true - would break a fundamental pillar of science.
The readings have so astounded researchers that they are asking others to independently verify the measurements before claiming an actual discovery.

I picture one science guy handing a piece of paper with a number on it to another science making dude and going "Does that say a bazillion miles per hour or is it just me?"
