Scorched And Blistered – The World of Planet Kelper-10B 

Planet Kepler-10b is a scorched blistering world, orbiting at a distance that’s more than 20 times closer to its star than Mercury is to our own Sun and takes less than one Earth day to orbit its star. The daytime temperature’s expected to be more than 2,500 degrees Fahrenheit, hotter than lava flows here on Earth, hot enough to melt iron! Intense radiation from the star has kept the planet from holding onto an atmosphere. Flecks of silicates and iron may be boiled off a molten surface and swept away by the stellar radiation, much like a comet’s tail when its orbit brings it close to the Sun.

 

The Kepler team has determined that Kepler-10b who’s discovery was announced in Jan. 2011 is a rocky planet, with a surface you could stand on, a mass 4.6 times that of Earth, and a diameter 1.4 times that of Earth and an average density of 8.8 grams per cubic centimetre – similar to that of an iron dumbbell. It is the smallest exoplanet – a planet located outside our solar system (dark spot against yellow sun) and the first concrete evidence of a solid rocky planet orbiting a star other than our Sun discovered to date.

The Kepler-10 star system is located about 560 light-years from our solar system. Planet Kepler-10b orbits one of the 150,000 stars that the Kelper spacecraft is monitoring with a 42 strong array of detectors aimed between the constellations of Cygnus and Lyra and just above the plane of the Milky Way Galaxy.

The star itself (Kelper 9)is very similar to our own sun in temperature, mass and size, but older with an age of over 8 billion years, compared to the 4-and-1/2 billion years of our own sun. . It’s one of the brighter stars that Kepler is monitoring and is a quiet star, slowly spinning with a weak magnetic field and few of the sun spots that characterize our own sun. It was the first star identified as potentially harbouring a very small transiting planet. The transits of the planet were first seen in July of 2009.

In May 2011, the Kepler team is announced another member of the Kepler-10 family, called Kepler-10c. It’s bigger than Kepler-10b with a radius of 2.2 times that of Earth’s, and it orbits the star every 45 days. Both planets would be blistering hot worlds. The Kepler-10 star system is the first star system found to have multiple transiting planets.

Sirius the Dog Star   31 comments

 

GalacticWolves3126Sirius the Dog Star

Alpha Canis Majoris

Sirius (Alpha Canis Majoris) the brightest star in the sky is located in the constellation of Canis Major -The Great Dog, named after the Dog Star. It can be seen from almost every inhabited region on Earth’s surface. And in the right conditions can be seen in day light.

It appears to be a single bright star but is actually a large binary star system. The main sequence star; Sirius A, is 22 times brighter than the Sun and 6th closest system to our own. Its faint companion star, Sirius B (the pup) was the first recognized white dwarf.


Electromagnetic fields

They orbit each other, every 49.98 years and Sirius B has a tremendous effect on the electromagnetic fields of our galaxy, the solar system, planets, and Earth itself. When at its closest to Sirius A the magnetic properties of Sirius B and it’s remarkable density, create massive magnetic storms resulting in the stars exchanging copious amounts of highly charged particles. These are injected into the galactic magnetic field of the Milky Way. Sirius’s magnetic storms are particularly intense around five years before their closest approach, and for up to five years following.

1944 occurrence, was during our history’s greatest conflict, World War II. And most recently almost 50 years later, in June, 1993 when, Sirius was hidden from Earth’s view by our Sun, the largest flood of the past century occurred. Mississippi, (Nile River), overflowed its banks and that flood continued through till mid-August. When Sirius re-appeared from behind the sun, the flood waters receded and the immediate life-threatening crisis subsided. A reflection of the great rivers of energies streaming out from Sirius?

Liberation

Sirius is associated with liberation. Ancient teachings say the very concept of freedom exists in human consciousness because of the Sirius system’s influence. And every year, on July 4, Sirius is hidden from view by our Sun -America’s Independence Day! And Bastille Day, the French Independence Day, is July 14.

As the most recent "great conjunction" of Sirius A and B occurred around 1993, a wave of freedom was sweeping our world that climaxed in the breakdown of the communist rule in Europe and the liberation of the Russian people from the hard-line Communist party. As the cold war finally concluded so the Berlin Wall fell … events that occurred simultaneously with the highest intensity of Sirius’s magnetic forces.


SiriusCelestial_Sirius Associations

Sirius has consistently been associated with a celestial dog throughout the classical world; China, identified the star as a Heavenly wolf.” Ancient Chaldea  (present day Iraq), knew it as the "Dog Star that Leads," / "Star of the Dog." Assyria, named it "Dog of the Sun" and ancient Akkadia, "Dog Star of the Sun."

Greece associated it with the heat of summer calling it “Seiros” the scorcher or the glowing. Hindu writings referred to it as “Sukra” the Rain God” or “Rain Star.”

The Dog is also described as "He who awakens the gods of the air, and summons them to their office of bringing the rain." The Wolf (Skidi) tribe of Nebraska knew it as the “Wolf Star.” Further north, the Alaskans called it “Moon Dog.”

 


Mythology

The Cherokee paired Sirius with Antares as a dog-star guardian of either end of the "Path of Souls; a watchman of the heavens. The ancient Egyptians believed Sirius was the doorway to the afterlife and for 70 days following July 4, when the star Sirius is hidden from view by the sun’s glare they refused to bury their dead because during this period the doorway was thought to be closed. 

In Greek times Aratus referred to Canis Major as Orion’s guard-dog, following its master’s heels, and standing on its hind legs carrying Sirius in its jaws. Manilius called it the "dog with the blazing face." Canis Major (large dog) seems to pursue the hare across the sky, the hare being represented by the constellation Lepus under Orion’s feet.

                                                          Mythol_Path of Souls Canis Major-Laelaps                                                          

In mythology it was said the constellation represented Laelaps, a dog so swift that no prey could outwit or escape it. Laelaps was given by Zeus to Europa, whose son Minos, King of Crete passed it on to Procris, daughter of Cephalus. The dog was given to Procris along with a javelin that could never miss. In a strange twist of fate Cephalus accidentally killed her in a hunting accident.

Inheriting the dog, Cephalus took it with him to Thebes, north of Athens, where a vicious but swift and uncatchable fox was terrorising the countryside. However no prey could ever escape the pursuit of Laelaps. Zeus’s answer to the unsolvable paradox of the inescapable dog in pursuit of the uncatchable fox, was to turn them both to stone placing the dog but not the offending fox, in the sky.


Ice wolves of Europa

Sirius is bluish white the dominant colour of the star and of the wolves and at rising and setting it flashes with the colours of the rainbow and the moon wolves.

The Ice Wolves of Europa are the “celestial wolves, the star chasers, the moon dogs of the night.” Known as the Moon Dog” and the Wolf Star” in mythology Sirius was one of the dogs given to Europa as a gift and a guardian. Today’s Ice wolves are – the most direct descendants of the original Pathfinder – the one known as “Star of the Celestial Wolf.”

Fire wolves of Io

All ancient sources described Sirius as a “red”, “fiery” and “copper” star. To Romans this meant “angry god” and they are known to have sacrificed red dogs to it and the hottest part of summer is still known as “Dog Days.”

Today Sirius is bright white, tinged with blue. The mystery remains.
