The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...

... 2004 March 29 . NASA's X-43A Scramjet Sets Air Speed Record . ... At Mach 7, seven times the speed of sound , the X-43A separated and the novel scramjet kicked in. Atmospheric oxygen was then scooped up, combined with onboard hydrogen , and combusted in flight to propel the X-43A to record air speeds during maneuvers over the next 10 seconds. ... The previously acknowledged air-speed record for jet-powered flight was Mach 3.3 for the decommissioned SR-71 . ... About APOD | ...

... Over the last decade the uninterrupted, high-resolution coverage of the Sun both from the excellent range of telescopes aboard many spacecraft and from ground-based instruments has led to a wealth of observations of small-scale dynamic events observed from the chromosphere to the transition region and corona. ... SoHO observations have further characterized many transient features, such as bi-directional jets, blinkers, coronal jets, and bright points. ...

. While looking at the galaxy cluster Abell 2667, astronomers found an odd-looking spiral galaxy (shown here in the upper left hand corner of the image) that ploughs through the cluster after being accelerated to at least 3.5 million km/h by the enormous combined gravity of the clusterтАЩs dark matter, hot gas and hundreds of galaxies.

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

... The picture shows a 2-dimensional sketch of the outflowing wind of a quasar (Elvis 2000, Astrophysical Journal , vol.545, p.63-76). In the funnel-shaped disk wind Elvis (2000) model a wind arises from a restricted range of radii on the accretion disk around the central black hole. Initially the wind makes a large angle to the disk plane (and so is roughly cylindrical). ... Looking through the quasi-cylindrical part of the wind we see UV and X-ray warm absorbers. ...
