Summary of white-noise components for 12 pulsars. The main panel shows the three contributions: radiometer noise as black squares, jitter noise as blue circles, and scintillation noise as red ...
A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...
A little bit of “scruff” in scientific data 50 years ago led to the discovery of pulsars — rapidly spinning dense stellar corpses that appear to pulse at Earth. Astronomer Jocelyn Bell made the chance ...
On February 24, 1968, an astronomy grad student Jocelyn Bell announced that she had discovered the first pulsar. A few months earlier, she noticed what she called a "bit of scruff" in the data from ...
In the Crab Nebula, a rapidly rotating neutron star, or pulsar (white dot near the center), powers the dramatic activity seen by Chandra. The inner X-ray ring is thought to be a shock wave that marks ...
Even Superman would have trouble picking up a chunk of a neutron star. Just a sugar cube-sized piece of this extremely dense material — the remnants of a collapsed star — weighs 1 billion tons. That's ...
Scientists from IIT Kanpur and NCRA Pune have developed a groundbreaking method to measure distances between Earth and ...
