What will happen when the fragments hit Jupiter? ... All the fragments will enter Jupiter's atmosphere at an angle of 42 degrees from the vertical and impact near a latitude of 44 degrees south, but on the back side of the planet as seen from Earth (about 10 degrees in longitude behind the edge of Jupiter, as seen from Earth). ... Any body moving through an atmosphere is slowed by atmospheric drag, by having to push the molecules of that atmosphere out of the way. ...

... Confirmation that a mysterious cloud of hydrogen in the Virgo Cluster is a dark galaxy has been published by a team of astronomers .

... LWN.net FAQ . ... This article is part of the LWN Porting Drivers to 2.6 series . The first big, disruptive changes to the 2.6 kernel came from the reworking of the block I/O layer. ... Buffer heads are no longer used in the block layer; they have been replaced with the new " bio " structure. ... The most significant change for block driver authors, though, may be the fact that partition handling has been moved up into the block layer, and drivers no longer need know anything about partitions. ...

... Like a last gasp of breath, Sun-like stars puff away their outer layers of gas at the end of their lives. This gas floats away into space and forms beautiful and striking clouds, which are called planetary nebulae (although they have nothing to do with planets). ... Yet, astronomers looking at 100 planetary nebulae in the bulging centre of our Galaxy, the Milky Way have found that most of the bipolar planetary nebulae in this region are acting in the same, strange, way. ...

1 kpc) sight lines were selected to investigate the distribution and physical conditions of gas located in low-density regions of the Galactic disk and halo. ... We find that a subsample of these sight lines has extinction curves with weak bumps and very steep far-UV extinction reminiscent of the Magellanic Clouds. ... The gas along these sight lines shows forbidden velocities, which may indicate that the dust has been subject to shocks. ...

... Because of the Sun 's UV radiation, Earth 's upper atmosphere is partly (0.1% or less) ionized plasma at altitudes of 70-1500 km. ... Around the plasma density maximum (F-layer, see below) a so-called ionospheric waveguide is formed for magnetosonic waves . ... It is interesting to note that this works also the other way round and, for example, the auroral kilometric radiation created by the precipitating particles high above the ionosphere does not reach the ground because of the ionospheric E...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
