Saturn's New Ring

January 31st 2010 05:24
An artist's impression on Satrun's new ring


Saturn was thought to have only seven rings named A through to E and few faint unnamed rings.
NASAS’s new telescope called the Spitzer Space Telescope was able discover a new undiscovered ring by picking up tiny particles of dust and ice using an infrared instrument.
The ring is about 1.5 million miles thick and at a much greater distance than Saturn's other famous rings, making it bigger than any other ring previously studied in the Solar system.

The largest known rings in the solar system was Saturn's E ring.
NASA's Jet Propulsion Laboratory, published the discovery, said the ring was probably made up of left over particles kicked off Saturn's moon Phoebe by small impacts from passing asteroids.

The telescope was able to pick up very small particles of ring dust, that shine with thermal radiation from the Sun, by using an infrared wavelength.

The ring's orbit is inclined at 27 degrees from the planet's main ring system. The bulk of it starts about 3.7 million miles (6 million km) away from the planet and extends another 7.4 million miles (12 million km).



The question is why did it take scientists so long to discover something so massive?

The ring is made up of ice and dust particles that are spread so far apart that if you happened to flying within this ring, you would be totally unaware you were actually in it.

Myths and Legends

January 29th 2010 03:49




Well it was bound to happen the urban myths and legends are on the rise despite any evidence to support them.

The newest myth gaining popularity on the internet is the notion that the world will experience a catastrophe on the winter solstice of 2012, either from collision with a (mythical) object called Nibiru sometimes referred to as planet X.

Some believe that planet X or Nibiru orbits beyond the asteroid belt so far there is no evidence that this object exists.

Nibiru a Babylonian term (also transliterated Neberu, Nebiru) is a term in the Akkadian language, translating to "crossing" or "point of transition" this term is referring to rivers or crossing of rivers.

The world is no stranger to these myths there have been many over the centuries.
In 1910 there was world wide concern that the comet Halley would poison the earth.
The comet’s tail did pass the orbit of the earth resulting in multiple meteor showers the earth’s atmosphere was not poised, humans are currently doing a good job of that.

The world will go through lets call it a catastrophe incident in the future after all it is a numbers game. Whether is a natural occurrence or fragment from space the evidence so far presented does not support the 2012 doomsday prediction.

The ancient Sumerians believed Neberu would caused chaos some 4000 years ago. I suspect that’s where the 2010 prediction comes from.

Although no one predicted the near miss in 2009 of asteroid 2009 DD45 this 200 feet wide piece of real estate came visiting at a distance of only 40000miles.

Forty thousand miles may sound like a heck of a lot, the reality is it's only about one-seventh of the way to the moon, and less than twice as far out as many telecommunications satellites.

This rock was a total surprise. These events are not time specific, this type of event could happen at any time anywhere with little warning.

Comet or Asteroid ?

January 23rd 2010 09:26



A mysterious comet-like object recently found in images obtained from a ground-based
telescopes might be fine particle debris from a high-speed asteroid collision, according to reports printed in some scientific journals.

The comet like object may contain rock and ice fragments that have sublimated forming a tail like appearance much like any ordinary comet.

P/2010 A2 is the 5th object classed as Main Belt Comet (MBC)
Main Belt Comets do not behave as normal comets, MBC objects orbit within the warmer, inner regions of the asteroid belt.

If this theory is confirmed, the object would represent the first time
astronomers have witnessed the debris of a high speed collision with another object in space.





Dubbed P/2010 A2 (LINEAR), the fuzzy, tailed mystery object is about 130,000
miles (210,000 kilometers) to 190,000 miles (305,000 kilometers) long. The debris looks like a fuzzy comet’s tail, stretching partway across the Solar system in the asteroid belt between Mars and Jupiter.

The asteroid belt contains thousands of asteroids of all shapes and sizes. The asteroid belt is about 250 million miles (402 million kilometers) from Earth.

Asteroids and Proto-planets

December 23rd 2009 03:46
Asteroids and proto-planet's the difference may seem a little confusing since the reclassification of Pluto’s status as a planet has been demoted to dwarf planet. There are a few significant large asteroids orbiting between the orbit of Jupiter and Mars.

Hi S.L.,
yes a bit like that. how a large ring be so delicate just goes to show how little we know about our planets. we are geting there slowly.

Hi S.L Happy New year to you

The companion star Sirius B may have or indeed had a planetary system at some point in time.

However it seems unlikely that any of the planets close to a dying Sun survived they would have been consumed as fuel. After Sirius B core collapsed it formed a much smaller version of itself.

It is possible to assume that if Sirius B had planets orbiting at a much greater distance they may have survived.

Since the light from any remaining planets is too dim for us to see from earth.

By watching the dwarf Star we could measure its “wobble” if any planet or planets big enough survived in the outer orbit they would cause a slight wobble in Sirius B.

Hi S.L

Yes would make plenty of ice cubes for Christmas drinks!!

This Ice burg is not the product of global warming but a natural shedding of ice.

Hello S.L.

Yes there is plenty of helium3 on the moon.
Would go a long way in renewing our energy sources where they are most needed.

Taxes well someone has to pay for the "good times" had by most company C.E.Os our reliance on oil has cost us plenty.

Thanks for the good thoughts S.L..It`s good to be back not quite at 100% yet.

Keep in touch.

Hi S.L and Fremen,
thank you for the comments. I agree with you S.L

The Nazca lines are indeed amazing. Another reason why the images so large is perhaps the wanted "gods above" to see there handiwork or as a means of communication with heavens above.

The crop circle form Fremen idea is interesting obviously the images were created for a reason. Whether it was religious or just paying homage for their existence is still an amazing sight to see in a time.

Yet despite the enormity of space we are still vulnerable to cosmic visitors.

Yes there are plans to expore Helium3 on the Moon.
This non-radioactive isotope is rare on earth.
The abundance of helium-3 is thought to be greater on the Moon.
Helium3 and 4 isotopes are to be used in clean fusion research.
