Watching Our Central Black Hole!

July 25, 2011 at 9:43 PM (curious research, late night studies)


The fascination with black holes continues to capture the imagination of humanity.  As many people remain curious about the nature of these fantastic celestial objects, scientists have been working to identify the actual truth on the existence of them.  Studies have included topics from the locations of the nearest black holes, to their actual sizes, to how they truly function.

We understand that black holes are the last levels of the lives of certain stars.  The stars that are more than three times as massive as our Sun collapse when they reach the ends of their lives.  This death phase reduces the star to a singular point of possibly infinite gravitational capacity, forming a black hole.

The gravitational pull within this area becomes so intense that nothing can escape it.  The region surrounding this point is called the event horizon, which is the border where nothing at or within it can get away from the black hole.  Aspects of spacetime that approach the event horizon become warped, and seem to enter the region at an incalculably slow pace.  Yet, upon finally entering the black hole, nothing can escape, and nothing can be seen again.

At the core region of the black hole is the singularity.  This is where gravity is so powerful that space-time itself begins to curve.  All of the mass within the black hole is at this area, yet it has no volume.  However, it is basically understood that the central region, the singularity, has an infinite level of density.

A supermassive black hole is believed to exist at the center of our Milky Way.  This is estimated to be 2.6 million times as massive as The Sun, and it is 27,000 light years of distance from Earth.  Scientists have identified the region to contain Sagittarius A*, a star with such luminous intensity that it must be powered by the strength of a black hole.

Chandra X-Ray Observatory has identified Sagittarius A*, seeing that it emits x-rays.  One such energetic burst was observed during 2001, when a three-hour long flare was ejected, recognized to be fifty times brighter than our Sun.  The flare was recorded as being one-hundred-million miles long, or twenty times as large as what scientists had predicted!

It is likely that a similar flare will occur at some point within the near future.  Research with Chandra X-Ray Observatory is being studied, with scientists working to locate this flare.  2012 conspiracy theorists try to pass the idea of a flare being emitted by The Sun next year, yet Earth will NOT be destroyed in the event of such an action!
