Artist's illustration of white dwarf pulsar. Astronomers have discovered what is only the second example of a white dwarf pulsar. The rare stellar remnant is spinning rapidly, and as it does so, it ...

Eventually, the pulsar slows down because the radiation it emits removes the energy from the system. In some cases, the ...

The James Webb Space Telescope has turned up a world that looks more like a squeezed citrus fruit than a planet, a distorted ...

Astronomers have discovered a unique double-star system that represents a “missing link” stage in what they believe is the birth process of the most rapidly-spinning stars in the Universe — ...

NASA's Imaging X-ray Polarimetry Explorer (IXPE) has produced the first-ever X-ray polarization data of the Vela pulsar wind nebula, which lies about 1,000 light-years from Earth in the constellation ...

Einstein’s theory of relativity has many strange consequences. Time moves slower for those traveling at high speeds, and massive objects like the Sun deform the space-time in which they sit, causing ...

Using a set of ground-based radio telescopes, an international team of astronomers has observed a slowly-spinning pulsar known as PSR J0901−4046. Results of the observational campaign, published on ...

An international team of astronomers have discovered the slowest-spinning radio pulsar yet known. The neutron star spins around only once every 23.5 seconds and is a challenge for theory to explain.

Turkish astronomers have inspected GLEAM-XJ162759.5–523504.3—a recently discovered pulsar with a relatively long spin period. Results of the study, published February 14 on the arXiv pre-print ...

A perplexing fast-spinning star just might be the "missing link" in a long-standing pulsar mystery, scientists say. The so-called neutron star — a city-sized stellar remnant born from the explosive ...

A pulsar that is rotating just once every 76 seconds raises questions about how long these star remnants can remain active. When a giant star explodes as a supernova, it can leave behind a dense core ...
