Zombie worlds: Five spooky planets orbiting dead stars

All stars, including the sun, have a finite lifetime. Stars shine by the process of nuclear fusion in which lighter atoms, such as hydrogen, fuse together to create heavier ones. This process releases vast quantities of energy ...

Neutron star HESS J1731-347 may be a 'strange' star

Researchers at the Institut für Astronomie und Astrophysik in Germany have found evidence that suggests the extremely tiny neutron star, HESS J1731-347, may in fact be a "strange" star. In their paper published in the journal ...

X-ray pulsar 1E 1145.1-6141 examined with NuSTAR

Indian astronomers have employed NASA's NuSTAR spacecraft to inspect an X-ray pulsar known as 1E 1145.1-6141. Results of the observations deliver important insights into the properties and nature of this pulsar. The study ...

New tool allows scientists to peer inside neutron stars

Imagine taking a star twice the mass of the sun and crushing it to the size of Manhattan. The result would be a neutron star—one of the densest objects found anywhere in the universe, exceeding the density of any material ...

Machine learning takes hold in nuclear physics

Scientists have begun turning to new tools offered by machine learning to help save time and money. In the past several years, nuclear physics has seen a flurry of machine learning projects come online, with many papers published ...

Hubble spots ultra-speedy jet blasting from star crash

Astronomers using NASA's Hubble Space Telescope have made a unique measurement that indicates a jet, plowing through space at speeds greater than 99.97% the speed of light, was propelled by the titanic collision between two ...
