Russell Alan Hulse (born November 28, 1950) is an American physicist and winner of the Nobel Prize in Physics, shared with his thesis advisor Joseph Hooton Taylor Jr., "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation". He was a specialist in the pulsar studies and gravitational waves.

Early years
Hulse was born in New York City and attended Bronx High School of Science and the Cooper Union before moving to University of Massachusetts Amherst (Ph.D. Physics 1975).
Middle years
There he worked with Taylor on a large-scale survey for pulsars using the Arecibo Observatory in Puerto Rico. It was this work that led to the discovery of the first binary pulsar.
In 1974, Hulse and Taylor discover binary pulsar PSR 1913+16 which is made up of a pulsar and black companion star. Neutron star rotation emits impulses extremely regular and stable in the radio waves and is nearby condensed material body gravitation (non-detectable in the visible field).Hulse, Taylor, and other colleagues have used this first binary pulsar to make high-precision tests of general relativity, demonstrating the existence of gravitational radiation in the amount. An approximation of this radiant energy is described by the "formula of the quadrupolar radiation" of Albert Einstein (1918).
In 1979, an announcement was made of measurements of small acceleration effect of the orbital movement of pulsar. This was initial proof that the system of these two masses moving emit gravitational waves.
Later years
After receiving his Ph.D., Hulse did postdoctoral work at the National Radio Astronomy Observatory in Green Bank, West Virginia. He returned to Princeton, where he has worked for many years at the Princeton Plasma Physics Laboratory. He has also worked on science education, and in 2003 joined the University of Texas at Dallas as a visiting professor of physics and of mathematics and science education.
In 1993, was coawarded the Nobel Prize in Physics. The Prize given to Taylor and Hulse was the first ever given for work in General Relativity (Gravity waves).
