Is the world's largest super-volcano set to erupt for the first time in 600,000 years?

Thursday, January 27, 2011

Yellowstone National Park, set aside as a national park on March 1, 1872, is located mostly in the U.S. state of Wyoming, though it also extends into Montana and Idaho.

July 22, 1980: Mount St Helens in Washington erupts. A Yellowstone caldera eruption would explode with a force a thousand times more powerful

The super-volcano beneath Yellowstone National Park in Wyoming has been rising at a record rate since 2004

It would explode with a force a thousand times more powerful than the Mount St Helens eruption in 1980.
Spewing lava far into the sky, a cloud of plant-killing ash would fan out and dump a layer 10ft deep up to 1,000 miles away.
Two-thirds of the U.S. could become uninhabitable as toxic air sweeps through it, grounding thousands of flights and forcing millions to leave their homes.


Twin suns - coming to a planet near you

* Betelgeuse losing mass
* Explosion will create "new sun"
* May be set for 2012 appearance

The second biggest star in the Orion constellation is losing mass, a typical indication that a gravitation collapse is occurring.
When that happens, we'll get our second sun, according to Dr Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland.
When this happens a giant explosion will occur, tens of millions of times brighter than the sun.

Some experts have speculated Betelgeuse’s explosion may cause a neutron star or result in the formation of a black hole approximately 1300 light years from Earth, but Dr Carter says it could go either way.


Dark-Matter Galaxy X

Sunday, January 16, 2011


An invisible Dark-Matter "Galaxy X" just outside our own. The invisibility of "Galaxy X"—as the purported body has been dubbed—may be due less to its apparent status as a dwarf galaxy than to its murky location and its overwhelming amount of dark matter, astronomer Sukanya Chakrabarti speculates.
Detectable only by the effects of its gravitational pull, dark matter is an invisible material that scientists think makes up more than 80 percent of the mass in the universe.

Chakrabarti, of the University of California, Berkeley, devised a technique similar to that used 160 years ago to predict the existence of Neptune, which was given away by the wobbles its gravity induced in Uranus's orbit.
Based on gravitational perturbations of gases on the fringes of our Milky Way galaxy, Chakrabarti came to her conclusion that there's a heretofore unknown dwarf galaxy about 260,000 light-years away.


Magnetic North Pole Shift Affects Tampa Airport

Sunday, January 9, 2011

The Earth's magnetic north pole is slowly heading toward Russia, according to scientists, but one of the places being affected by this is Tampa International Airport.
Airport officials closed its main runway this week until Jan. 13 to adjust the taxiway signs accounting for the magnetic pole shift

Magnetic changes in Earth's core are causing this, possibly due to "a region of rapidly changing magnetism on the core's surface," according to National Geographic.
