All of the Apocolypse 2012 fanatics are having a blast with this topic! The thought of it does present some levels of frustration to anyone whom is paying attention. Yet, there does seem to be a strong level of evidence that provides relief to the idea of anything relating to this particular issue happening next year.
The class III red supergiant star, Alpha Orionis, familiarly known as Betelgeuse, is about to blow! It is in the last stages of it’s life, and it is quickly depleting it’s inner helium fuel source. At that point, the already enormous star will expand even further, as it’s core falls inward. When all of the helium has depleted, and it’s expansion has reached the limit, Betelgeuse will go bang!
Some astronomical reviewers are saying that this could happen any day now! Once it explodes, the greatest threat to anything in the way will be the shock waves from the blast. All things within the immediate vicinity will be pulverized. Yet, Betelgeuse is roughly between 430 and 520 light years away from us, which is supposed to be enough distance to where it’s explosive end will not affect our world.
The age of Betelgeuse has it labeled as a first generation star. It was supposed to have been formed shortly after The Big Bang. It is located within The Orion-Cygnus Arm, a spur of The Milky Way, just as we are situated. Some astronomers are proposing that the star was “a runaway”, having moved from it’s initial location. Betelgeuse supposedly was located within the Orion OB1 Association, at first, and it has shifted from it’s primary position.
This star is the nearest red giant star to us, at a distance of 160 light years, or 520 parsecs. Our Sun, along with Betelgeuse, are close to stars that include Alnilam, Alnitak, and Mintaka, the stars of Orion’s Belt, along with Bellatrix and Rigel. Betelgeuse is within the constellation of Orion The Hunter. It’s classification is M, which is said to be the most common type of star.
As a claification, there is no need to fear the explosion of Betelgeuse to be a part of the alleged 2012 end of all things! Astronomy experts, those whom actually know what they are talking about, are saying that it will explode soon, which could be at any time between this hour and the next 100,000 years. Yet, it usually does take some time for the stars to degrade into levels that take them to the points of supernova, and Betelgeuse is not displaying that absolute end-stage setting. Not yet…

NOT AGAIN!!! A 1.7 ton German satellite that has broken into over thirty pieces will crash somewhere on the planet Sunday morning, and no one knows where!
A supernova has to be such a spectacular sight! Stars are blowing up regularly, at different areas of the galaxy, and indeed throughout the universe. They do serve as robust reminders of how life does come to and end. Yet, if you are going to go out with a bang, then what better way to do it?
An astronomy class at The University of Delaware had the fortune to get an image of an exploding star within M101, The Pinwheel Galaxy. While on a study trip to their campus’ affiliated Mount Cuba Astronomical Observatory, the class took advantage of the time alloted to use the telescope. It was during this time that they observed an occurring supernova!
This supernova is the end-stage of the star PTF 11kly. It is classified as a Type 1a supernova, meaning that it is a part of a binary star system. Of the two stars within this system, one is a g-class / main sequence star, and the other is a white dwarf star. This kind of supernova goes so that the white dwarf pulls energy from it’s larger partner, reaching a point when it is at a critical mass. This leads to the star collapsing, then producing the explosion of a supernova.
The excessive levels of fusion within the core of this type of star creates the energy for the stellar blast. As intense amounts of carbon and oxygen combine, the excessive energy becomes too great to be maintained by the star. Thus, an explosion, a supernova, occurs!
PTF 11kly was discovered in 1781. The French astronomer Pierre Mechain was the initial reporter of it’s existence. It is located within our constellation-classification of Ursa Major, which contains The Big Dipper, This stellar conglomeration is some twenty-one million light years away from us. The Type 1a supernova was first photographed August 23, 2011, at The Palomar Transient Factory (PTF), and it is getting brighter!

This one particular theory surrounding the creation of our solar system is interesting. It poses some theories that may seem far out, yet logic could allow them to be plausible. Particularly, I am not surprised about suggestions of Jupiter’s culpability in the matter!
Yes; a big ol’ bully! We will return to that issue. Some theories are emerging, which suggest that our solar system once was the home to an extra planet. Actually, the ideas about the structure of the early solar system say that many additional worlds were here, in addition to the eight (nine…) that we claim today. One particular theory proposes the idea of a fifth gas giant having been located within The Sun’s gravitational realm.
The generally accepted ideas surrounding the formation of the early solar system state that the planets were packed within a seemingly constricted bond. As the forces of gravity eventually dominated, each of the planets moved toward their currently recognized locations. However, some current research suggests that there were more bodies within the solar system than could be sustained by the gravitational powers of The Sun and the major planets.
One particular theory is suggesting that our planets formed in areas that all were closer to The Sun. The inner planets were able to remain, more or less, within stable positions that were practically near to our star. Yet, the gas giants, being composed of lighter elements, were able to escape the inner regions of the solar system, floating out toward their current locations. This theory is saying that more gas giants were present, at first, and that the forces of gravity eventually won, with any lesser planets being dismissed from the bunch.
This idea is stating that our solar system’s gas giant worlds, Jupiter, Saturn, Uranus, and Neptune, likely formed in locations that were much closer to our Sun. Scientists are saying that all of the matter needed to form planets, especially those of immense sizes, would not have existed at locations distant from the central solar system. This matter would have been necessary to create the large worlds, and it would have been located nearer to the central formation region of the solar system. Thus, all of the matter needed to create Jupiter, Saturn, Uranus, and Neptune, should have been nearer to The Sun, as should have been these worlds.
A proposed theory states that, as the planets were settling into their current locations, an alleged fifth gas giant existed within the solar system. Yet, it could not reach a stable orbital position, and it was accosted by the gravitational forces of the other gas giants. It seems that Jupiter in particular was the lead bully, exerting it’s excessive force within the general solar system, and forcing all that could not hang to be ejected!
So went gas giant five! Jupiter, Saturn, Uranus, and Neptune were able to shift into their current positions, gravitationally bound to The Sun and the solar system’s other worlds. This alleged fifth giant was pushed out, something akin to a rubber ball stuck between a series of bricks. The gravity being exerted by all of the other planets was too much for this fifth gas giant to handle, and it was forced out!
If this is/was the case, then it is possible that this rejected world could still be out there. Perhaps it is floating alone in space, a wondering world, a rogue planet, as some have suggested. This idea is possible for several planets that may be amok throughout the galaxy, not gravitationally linked to any other planets, or to any host stars. It was this past May when Japanese astronomers announced that they had located a lone-wolf world that was floating in space, not linked to a star, or to any other planets!
Some of these suppositions suggest that several lone wanderers, homeless planets, are rampant throughout our galaxy. However, it is unlikely that any of them are terrestrial planets, similar to Earth. They likely are gas giants, light, and capable of floating without being immediately bound to a stronger gravitiational force. Amazingly, they even could have moons orbiting them! These moons could be able to sustain heat from the forces of gravity given off by their host worlds, which could allow these moons possibly to develop the conditions necessary for supporting life!
