Our Solar System

**Chris Hamilton** · 10-01-2010, 07:25 AM

i decided to place this in solar system thread because i think this news is more of a discussion of our sun and planets being affected by outside energy. ibex is just simply amazing and the information derived from studying its data is so important in david's research of our planetary and solar dynamics!

ibex site. the main author of the original 9/27 article published in the journal of geophysical research (space physics) is david mccomas, whose bio is in current missions/ibex at this site

exciting stuff! chris

mysterious ribbon at edge of solar system is changing

a year ago, researchers from the ibex mission – nasa’s interstellar boundary explorer – announced the discovery of an unexpected bright band or ribbon of surprisingly high energy emissions at the boundary between our solar system and interstellar space. now, after a year of observations, scientists have seen vast changes, including an unusual knot in the ribbon which appears to have ‘untied.’ changes in the ribbon — a ‘disturbance in the force,’ so to speak, along with a shrunken heliosphere, may be allowing galactic cosmic rays to leak into our solar system.

“we didn’t understand where the ribbon came from in the first place,” said david mccomas, ibex principal investigator, during a press briefing. “it’s even more confounding now, to know the structure can change on incredibly short timescales.”

our "new, improved" solar system
fasten your seatbelts, folks — i'm about to take you on a wild ride!

nasa's solar system
as portrayed on the home page for the nasa/jpl photojournal, our solar system is an orderly arrangement of planets orbiting the sun.
nasa / jpl
compared with the systems of planets being found around other stars, our solar system is an orderly place, with each planet tracking around the sun in a stable, roughly circular orbit. for centuries, the planets' long-term stability has been taken as evidence that they formed where they are now, sucking up gas, dust, and larger building blocks from the protoplanetary disk around them until reaching their final sizes.

but dig a little deeper, and you find serious problems with that simplistic view. for example, uranus and neptune should have ended up much smaller and less massive, because billions of miles from the infant sun the protoplanetary pickings were slim and the assembly process too slow. conversely, mars formed in the fat of the disk and should have ended up at least 10 times more massive than it is today. and no one really understands the asteroid belt's existence — particularly why it's crudely divided into rocky bodies (called s types) nearer the sun and dark, carbon-dominated hunks (c types) farther out.

dynamicists solved the uranus-neptune dilemma several years ago by positing that the four giant planets were initially a much closer-knit family, coming together in a cozy zone 5 to 12 astronomical units from the sun.

nasa's fermi telescope finds giant structure in our galaxy

washington -- nasa's fermi gamma-ray space telescope has unveiled a previously unseen structure centered in the milky way. the feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy.

"what we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center," said doug finkbeiner, an astronomer at the harvard-smithsonian center for astrophysics in cambridge, mass., who first recognized the feature. "we don't fully understand their nature or origin."

the structure spans more than half of the visible sky, from the constellation virgo to the constellation grus, and it may be millions of years old. a paper about the findings has been accepted for publication in the astrophysical journal.

finkbeiner and his team discovered the bubbles by processing publicly available data from fermi's large area telescope (lat). the lat is the most sensitive and highest-resolution gamma-ray detector ever launched. gamma rays are the highest-energy form of light.

i wondered whether that was the 'dark rift' they mayans talked of??

the mercury mt-based exponential planetary framework and the phi-series
although the exponential function p(x) = mt phix (x = -2 to 16, base mt = 0.240842658 years ) generates successive mean sidereal and mean synodic periods, it is nevertheless the mean sidereal period of mercury mk 0 = mt that provides the initial starting point for mercury-based exponential period functions...

the magnetic field pattern of the milky way

new all-sky map shows complex structure of magnetic fields in unprecedented detail
december 06, 2011

like all galaxies, our milky way is awash with magnetic fields. for the first time, scientists have now measured the complex structure of such fields in detail. using a novel image reconstruction technique, they combined data from more than 41,000 individual measurements. the work was a collaboration between scientists at the max planck institute for astrophysics who are specialists in the new discipline of information field theory, and an international team of radio astronomers. the new map not only reveals the structure of the galactic magnetic field on large scales, but also small-scale features that provide information about turbulence in the galactic gas.

despite intensive research, the origin of galactic magnetic fields is still unknown. one assumes, however, that they are built up by dynamo processes in which mechanical energy is converted into magnetic energy. similar processes occur in the interior of the earth, the sun and in the broadest sense, in the gadgets that power bicycle lights through peddling. by revealing the magnetic field structure throughout the milky way, the new map provides important insights into the machinery of galactic dynamos.
one way to measure cosmic magnetic fields, which has been known for over 150 years, makes use of an effect known as faraday rotation. when polarized light passes through a magnetized medium, the plane of polarization rotates. the amount of rotation depends, among other things, on the strength and direction of the magnetic field. therefore, observing such rotation allows one to investigate the properties of the intervening magnetic fields.

Hey guys. I just wanted to share some pics of the Transition of Venus that occured today. Took them with my iPhone and my telescope. You'll never see it again in this lifetime (unless the average life expectancy goes up dramatically lol!) This will not happen again for another 105 years and will happen in pairs... 2117 and 2125. A cyclical event that has been documented and followed by ancient civilizations for thousands of years...
