Unique no longer, as other planets found orbiting distant pulsar...
PHYSICS Russell Hulse, 42, and Joseph Taylor, 52, both of Princeton, provided the first support for a crucial prediction made by Albert Einstein in his general theory of relativity. The breakthrough came in the early 1970s as they searched the sky for pulsars, the superdense cinders left over when stars explode. Hulse and Taylor were first to find a double pulsar, a pair of objects whirling around each other in tight formation. Einstein's theory decreed that two such heavy bodies orbiting each other should give off gravity waves, which would drain off energy and cause the objects to come...
Princeton professors Russell A. Hulse, 42, and Joseph H. Taylor Jr., 52, won the prize in physics for their discovery of the first binary pulsar...
...Pulsars are dying stars that emit regular bursts of light that can be detected with radio telescopes. The Taylor-Hulse pulsar system consists of two pulsars orbiting each other, and provides a highly accurate way to test Einstein's general theory of relativity...
...also emits radiation that plows through the sparse gases of interstellar space. The radiation, says Cornell astronomer James Cordes, who co-authored a report on the pulsar in this week's Nature, "creates a wake, like a boat going across a choppy lake." Seeing how the wake, which appears to be shaped roughly like a guitar, interacts with other matter will help scientists understand what lies in the spaces between the stars. The very existence of one high-velocity pulsar implies that there must be others, some of which have undoubtedly escaped into deep space. Scientists hope...
