Latest Comet tail Stories
The classic image of black hole systems is the in-flowing gas being consumed by the singularity. However, black holes are far from simply being cosmic vacuum cleaners, and occasionally even exhibit some strange behavior.
In March 2015, NASA will launch four identical spacecraft to study how magnetic fields around Earth connect and disconnect, explosively releasing energy – a process known as magnetic reconnection.
Using observations from two different NASA spacecraft, scientists have shed new light on the process behind solar flares and eruptions: magnetic reconnection.
Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...
