Pulsars
A Pulsar is Blasting out Jets of Matter and Antimatter
Why is there so much antimatter in the Universe? Ordinary matter is far more plentiful than antimatter, but scientists keep…
Astronomers Scan 800 Pulsars to See If Any of Them Have Planets
Astronomers discovered the first exoplanets in 1992. They found a pair of them orbiting the pulsar PSR B1257+12 about 2300…
Twin Stars Prove Einstein at Least 99.99% Right
A 16-year study by an international team of astronomers has confirmed Einstein's Theory of General Relativity and witnessed some predicted…
Astronomers can use Pulsars to Measure Tiny Changes of Acceleration Within the Milky Way, Scanning Internally for Dark Matter and Dark Energy
Dark matter within our galaxy is difficult to map, but a team of astronomers has used pulsars to measure its…
Astronomers Measure a 1-billion Tesla Magnetic Field on the Surface of a Neutron Star
We recently observed the strongest magnetic field ever recorded in the Universe. The record-breaking field was discovered at the surface…
Why Pulsars Are So Bright
When pulsars were first discovered in 1967, their rhythmic radio-wave pulsations were a mystery. Some thought their radio beams must…
A Star Has Been Found That Pulsates, But Only on One Side
An international team of astronomers have found the first-ever example of a pulsating star that emits energy from only one…
Halo Around a Pulsar could Explain Why We See Antimatter Coming from Space
Astronomers have been watching a nearby pulsar with a strange halo around it. That pulsar might answer a question that's…
Astronomers Map the Surface of a Pulsar
Using NICER data, two teams of researchers were able to map the surface of a pulsar for the first time…
This is the Milky Way’s Magnetic Field
The Milky Way galaxy has its own magnetic field. It's extremely weak compared to Earth's; thousands of times weaker, in…
