While you may never have pondered the similarity between a common bar magnet and a    star,&nbsp;astronomers do, and they believe they have figure out why the two disparate bodies are    sometimes strikingly similar.

Magnetospheres, the giant magnetic fields around planets, are extraordinarily good at trapping plasma. To study them, and gain insights into how to produce fusion power, a group of scientists builds a mini magnetosphere at MIT. By Rachel Metz.

Astronomers have found what they say is the best evidence yet for water, or at least steam, in the atmosphere of a planet around another star.

Recent observations have uncovered evidence that helps to confirm the identification of the remains of one of the earliest stellar explosions recorded by humans. The new study shows that the supernova remnant RCW 86 is much younger than previously thought.

Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge.

European Space Agency -- ESAÃ¢ÂÂs quartet of space-weather watchers, Cluster, has discovered vortices of ejected solar material high above the Earth.     The superheated gases trapped in these structures are probably tunnelling their way into the EarthÃ¢ÂÂs magnetic Ã¢ÂÂbubbleÃ¢ÂÂ, the magnetosphere...

A supernova spotted by the Danish astronomer Tycho Brahe more than four centuries ago - which changed the course of human knowledge - has just yielded a further discovery: the companion star that triggered the great event.

Astronomers have found a new class of objects in space: a neutron star orbiting inside a cocoon of cold gas and/or dust that hides a bloated supergiant star.
