and the stellar core—now a neutron star—lies in the center of the nebula. In the 1920s, astronomers like Edwin Hubble noticed that the Crab Nebula was getting bigger in photos of the night sky.

A supernova is one of the most powerful and mysterious phenomena in the universe. It’s an event that occurs when a star reaches the end of its life, triggering an explosion that releases immense ...

The Crab Nebula is an example of a supernova remnant. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The rapidly spinning neutron star embedded in the center ...

The mission, later renamed Fermi, was launched in 2008 and continues to produce significant insights in topics ranging from neutron stars and black holes ... rapid particle acceleration phenomena in ...

Recent research has uncovered what appears to be the grizzly death of an exoplanet in the nearby Helix Nebula, which seems to have been devoured by a dying star. Researchers have been detecting X ...

Get Instant Summarized Text (Gist) Simulations indicate that the low-mass star in the J0453+1559 binary system could be a neutron star rather than a white dwarf. The star's mass, 1.174 M ⊙, is ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of ...

Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods.

Neutron stars are exotic and extremely compact stellar remnants. Only black holes have a higher mass density. While black holes colliding with each other can only be detected by the emitted ...
