First sky maps from IBEX

IBEX, the Interstellar Boundary Explorer, studies the boundary between the heliosphere and the interstellar medium by observing energetic neutral atoms created as the solar wind hits interstellar gas. They have just released the first scientific results and associated sky maps from the data collected by IBEX. There's a surprise within the results: IBEX observed a ribbon around the heliosphere that is a dense source of energetic neutral atoms, something that was completely unpredicted by any of the theoretical models. There also seems to be fine structure within the ribbon, something else completely unpredicted and suggesting something weird is going on in the boundary between the heliosphere and the interstellar medium.

It is still unknown what the ribbon is, but the fact that it is suspiciously aligned with the local galactic magnetic field might be a hint. And it does not seem to be a screwup with IBEX or due to a local source of energetic neutral atoms: the data from IBEX roughly agrees with observations made by Cassini's Ion and Neutral Camera, which was primarily used to study Saturn's magnetosphere but also captured data about the heliosphere.

    The wonders of our world will be augmented with a brand new concept of multiple dimensional worlds that are of concern to all men.
    With the existence of 'Techie Worlds' (available at amazon.com) believers in Christianity can hold their views utilizing sound logic, clear thinking and a mechanistic view of worlds. Applying Flatland's concept of contiguous dimensional worlds, Trinity, Resurrection, Judgment and soul are sensible and mechanically viable beliefs. 'Techie Worlds' follows that rule of science by which individual details are tested for their conformity to the overarching hypothesis. Admittedly, agnostics may choose not to follow such obvious and sensible logic, but no longer can they denigrate believers for fuzzy thinking. Moslems and pagans who read and understand the sound logic of the Flatland concept must adopt the reasonable Trinitarian view. 'Techie Worlds' will make them abandon the ways of terror an adopt the way of love. Techie Worlds is not standard preacher-prattle. Only by reading it can you open your mind to its valid way of understanding Christianity.
