A rare cosmic phenomenon - a double pulsar - has enabled the Albert Einstein's theory of general relativity to be tested under extreme conditions, the British Association was told by Dr Michael Kramer of the Jodrell Bank Observatory.
The two exotic stars orbit each other at speeds of 621,000 mph,...
There are three subtypes of U Geminorum star (UG):SS Cygni stars (UGSS), which increase in brightness by 2-6 mag in V in 1-2 days, and return to their original brightnesses in several subsequent days.SU Ursae Majoris stars (UGSU), which have brighter and longer "supermaxima" outburst...
Kepler discovery of a unique triply eclipsing triple star While the quest for Earth-like planets around other stars using the NASA's Kepler space telescope has recently produced many exciting discoveries, other branches of stellar astrophysics also benefit from the ultraprecise space...

The Brief but Violent Life of Monogenetic Volcanoes A new study in the journal Geology is shedding light on the brief but violent lives of maar-diatreme volcanoes, which erupt when magma and water meet in an explosive marriage below the surface of the earth. Maar-diatremes belong to a family of volc...
