Comet defies death, brushes up to sun and lives




WASHINGTON (AP) — A small comet survived what astronomers figured would be a sure death when it danced uncomfortably close to the broiling sun.
Comet Lovejoy, which was only discovered a couple of weeks ago, was supposed to melt Thursday night when it came close to where temperatures hit several million degrees. Astronomers had tracked 2,000 other sun-grazing comets make the same suicidal trip. None had ever survived.
But astronomers watching live with NASA telescopes first saw the sun's corona wiggle as Lovejoy went close to the sun. They were then shocked when a bright spot emerged on the sun's other side. Lovejoy lived.
"I was delighted when I saw it go into the sun and I was astounded when I saw something re-emerge," said U.S. Navy solar researcher Karl Battams.
Lovejoy didn't exactly come out of its hellish adventure unscathed. Only 10 percent of the comet — which was probably millions of tons — survived the encounter, said W. Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory, which tracked Lovejoy's death-defying plunge.
And the comet lost something pretty important: its tail.
"It looks like the tail broke off and is stuck" in the sun's magnetic field, Pesnell said.
Comets circle the sun and sometimes get too close. Lovejoy came within 75,000 miles (121,000 kilometers) of the sun's surface, Battams said. For a small object often described as a dirty snowball comprised of ice and dust, that brush with the sun should have been fatal.
Astronomers say it probably didn't melt completely because the comet was larger than they thought.
The frozen comet was evaporating as it made the trip toward the sun, "just like you're sweating on a hot day," Pesnell said.
"It's like an ice cube going by a barbecue grill," he said.
Pesnell said the comet, although only discovered at the end of November by an Australian observer, probably is related to a comet that came by Earth on the way to the sun in 1106.
As Comet Lovejoy makes its big circle through the solar system, it will be another 800 or 900 years before it nears the sun again, astronomers say.

Experts stumped by ancient Jerusalem markings

JERUSALEM (AP) — Mysterious stone carvings made thousands of years ago and recently uncovered in an excavation underneath Jerusalem have archaeologists stumped.
Israeli diggers who uncovered a complex of rooms carved into the bedrock in the oldest section of the city recently found the markings: Three "V'' shapes cut next to each other into the limestone floor of one of the rooms, about 2 inches (5 centimeters) deep and 20 inches (50 centimeters) long. There were no finds to offer any clues pointing to the identity of who made them or what purpose they served.
The archaeologists in charge of the dig know so little that they have been unable even to posit a theory about their nature, said Eli Shukron, one of the two directors of the dig.
"The markings are very strange, and very intriguing. I've never seen anything like them," Shukron said.
The shapes were found in a dig known as the City of David, a politically sensitive excavation conducted by Israeli government archaeologists and funded by a nationalist Jewish group under the Palestinian neighborhood of Silwan in east Jerusalem. The rooms were unearthed as part of the excavation of fortifications around the ancient city's only natural water source, the Gihon spring.
It is possible, the dig's archaeologists say, that when the markings were made at least 2,800 years ago the shapes might have accommodated some kind of wooden structure that stood inside them, or they might have served some other purpose on their own. They might have had a ritual function or one that was entirely mundane. Archaeologists faced by a curious artifact can usually at least venture a guess about its nature, but in this case no one, including outside experts consulted by Shukron and the dig's co-director, archaeologists with decades of experience between them, has any idea.
There appears to be at least one other ancient marking of the same type at the site. A century-old map of an expedition led by the British explorer Montague Parker, who searched for the lost treasures of the Jewish Temple in Jerusalem between 1909 and 1911, includes the shape of a "V'' drawn in an underground channel not far away. Modern archaeologists haven't excavated that area yet.
Ceramic shards found in the rooms indicate they were last used around 800 B.C., with Jerusalem under the rule of Judean kings, the dig's archaeologists say. At around that time, the rooms appear to have been filled with rubble to support the construction of a defensive wall.
It is unclear, however, whether they were built in the time of those kings or centuries earlier by the Canaanite residents who predated them.
The purpose of the complex is part of the riddle. The straight lines of its walls and level floors are evidence of careful engineering, and it was located close to the most important site in the city, the spring, suggesting it might have had an important function.
A unique find in a room beside the one with the markings — a stone like a modern grave marker, which was left upright when the room was filled in — might offer a clue. Such stones were used in the ancient Middle East as a focal point for ritual or a memorial for dead ancestors, the archaeologists say, and it is likely a remnant of the pagan religions which the city's Israelite prophets tried to eradicate. It is the first such stone to be found intact in Jerusalem excavations.
But the ritual stone does not necessarily mean the whole complex was a temple. It might simply have marked a corner devoted to religious practice in a building whose purpose was commonplace.
With the experts unable to come up with a theory about the markings, the City of David dig posted a photo on its Facebook page and solicited suggestions. The results ranged from the thought-provoking — "a system for wood panels that held some other item," or molds into which molten metal would could have been poured — to the fanciful: ancient Hebrew or Egyptian characters, or a "symbol for water, particularly as it was near a spring."
The City of David dig, where the carvings were found, is the most high-profile and politically contentious excavation in the Holy Land. Named for the biblical monarch thought to have ruled from the spot 3,000 years ago, the dig is located in what today is east Jerusalem, which was captured by Israel in 1967. Palestinians claim that part of the city as the capital of a future state.
The dig is funded by Elad, an organization affiliated with the Israeli settlement movement. The group also moves Jewish families into the neighborhood and elsewhere in east Jerusalem in an attempt to render impossible any division of the city in a future peace deal.
Palestinians and some Israeli archaeologists have criticized the dig for what they say is an excessive focus on Jewish remains. The dig's archaeologists, who work under the auspices of the government's Israel Antiquities Authority, deny that charge.

Supermoon will occur for the first time since 1993

EUGENE (KMTR) – A moon perigee will occur for the first time since 1993.

This year the “supermoon” will coincidentally happen in conjunction with a full moon phase. Scientists say a perigee is when the moon’s oval orbit will be closest to Earth. It will appear nearly 14% bigger and 30% brighter than usual.

The moon’s distance typically varies around 410,000 kilometers, but tonight it will be about 356,575 kilometers.

Ocean tide has proven greatest when the moon is full. During the perigee, tidal force has in the past been stronger with more dramatic highs and lows.

Scientists speculate that there could be a link between supermoons and natural disasters. Disasters occurring in the same year of supermoons, they say, were influenced by the increased gravitational strength. However those who contend this idea say unless a disaster happens on the actual date of the supermoon, monthly alternation between the Earth and moon’s points of furthest proximity and closest proximity are not supportive.

Astrologers have most recently argued that the Japanese earthquake and tsunami was brought on by tonight’s anticipated perigee. It is the closest the moon has been since 1993. Earlier in the month, however, the moon was about 400,000 kilometers from Earth – close to a distance defining apogee (the furthest point from the world).

The next expected supermoon, although not a complete perigee, is expected November 14th, 2016.

Are You Sad Today??

Here are verses from the Kahlil Gibran's poem, The Prophet...

Your joy is your sorrow unmasked.

...The deeper that sorrow carves into your being, the more joy you can contain.

...When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight.

Friday, August 20, 2010

As an introduction.. I would like to embrace a poetic writings of Kahlil Gibran from his book The PROPHET.. a friend of mine suggest this to me a while ago and i find this very interesting .. so journey with me into the verses On Love...

Then said Almitra, "Speak to us of Love."
And he raised his head and looked upon the people, and there fell a stillness upon them. And with a great voice he said:
When love beckons to you follow him,
Though his ways are hard and steep.
And when his wings enfold you yield to him,
Though the sword hidden among his pinions may wound you. And when he speaks to you believe in him,
Though his voice may shatter your dreams as the north wind lays waste the garden.
For even as love crowns you so shall he crucify you. Even as he is for your growth so is he for your pruning.
Even as he ascends to your height and caresses your tenderest branches that quiver in the sun,
So shall he descend to your roots and shake them in their clinging to the earth. Like sheaves of corn he gathers you unto himself.
He threshes you to make you naked.
He sifts you to free you from your husks.
He grinds you to whiteness.
He kneads you until you are pliant;
And then he assigns you to his sacred fire, that you may become sacred bread for God's sacred feast.
All these things shall love do unto you that you may know the secrets of your heart, and in that knowledge become a fragment of Life's heart.
But if in your fear you would seek only love's peace and love's pleasure,
Then it is better for you that you cover your nakedness and pass out of love's threshing-floor,
Into the seasonless world where you shall laugh, but not all of your laughter, and weep, but not all of your tears.
Love gives naught but itself and takes naught but from itself.
Love possesses not nor would it be possessed; For love is sufficient unto love. When you love you should not say, "God is in my heart," but rather, I am in the heart of God."
And think not you can direct the course of love, if it finds you worthy, directs your course.
Love has no other desire but to fulfil itself.
But if you love and must needs have desires, let these be your desires:
To melt and be like a running brook that sings its melody to the night.
To know the pain of too much tenderness.
To be wounded by your own understanding of love;
And to bleed willingly and joyfully.
To wake at dawn with a winged heart and give thanks for another day of loving;
To rest at the noon hour and meditate love's ecstasy;
To return home at eventide with gratitude;
And then to sleep with a prayer for the beloved in your heart and a song of praise upon your lips.
