Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago.

Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the Universe, according to a decades-long study of a distant pulsar.

A fast-moving pulsar appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at a speed of about 4 million miles per hour.

A team of highly determined high school students discovered a never-before-seen pulsar by painstakingly analyzing data from the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT).

A team of astronomers, including Danai Antonopoulou and Anna Watts from the University of Amsterdam, has discovered that sudden speed jumps in the rotational velocity of pulsars have a minimum size, and that they are caused not by the unpinning and displacement of just one sub-surface superfluid vortex, but by billions.

A newly discovered system of two white dwarf stars and a superdense pulsar-all packed within a space smaller than the Earth's orbit around the sun-is enabling astronomers to probe a range of cosmic mysteries, including the very nature of gravity itself.

Astronomers have discovered a magnetar at the centre of our Milky Way. A magnetar is a type of neutron star with an extremely powerful magnetic field.

Astronomers have used ESO's Very Large Telescope, along with radio telescopes around the world, to find and study a bizarre stellar pair consisting of the most massive neutron star confirmed so far, orbited by a white dwarf star.

High School students have discovered a new star that spins as fast as a Formula 1 race car's engine. This discovery may someday help astronomers detect ripples in spacetime known as gravitational waves.
