nasa voyager finds magnetic bubbles at solar system039s edge
Bookmarked 771 weeks ago
the sun039s magnetic field spins opposite directions on the north and south poles these oppositely pointing magnetic fields are separated by a layer of current called the heliospheric current sheet due to the tilt of the magnetic axis in relation to the axis of rotation of the sun the heliospheric current sheet flaps like a flag in the wind the flapping current sheet separates regions of oppositely pointing magnetic field called sectors as the solar wind speed decreases past the termination shock the sectors squeeze together bringing regions of opposite magnetic field closer to each other the voyager spacecraft have now found that when the separation of sectors becomes very small the sectored magnetic field breaks up into a sea of nested quotmagnetic bubblesquot in a phenomenon called magnetic reconnection the region of nested bubbles is carried by the solar wind to the north and south filling out the entire front region of the heliopause and the sector region in the heliosheaththis discovery has prompted a complete revision of what the heliosheath region looks like the smooth streamlined look is gone replaced with a bubbly frothy outer layerthis video is public domain and can be downloaded at: http:svsgsfcnasagovgoto10790like our videos subscribe to nasa039s goddard shorts hd podcast:http:svsgsfcnasagovvisitunesf0004_indexhtmlor find nasa goddard space flight center on facebook:http:wwwfacebookcomnasagsfcor find us on twitter:http:twittercomnasagoddard

subscribe to the deepastronomy itunes podcast: http:feedsfeedburnercomblipnxliand add to ituneson january 10th 2011 after gathering and analyzing over 8 months of data transmitted from the spacecraft the kepler science team announced the discovery of the first rocky earth-sized world: kepler 10bthe good news is that this world is roughly the size of the earth it is 14 times that of our home the bad news is kepler 10b does not lie within the coveted habitable zone the orbit of this planet around its star is 20 times closer than mercury is to the sun it would be extremely unlikely to find life here
