Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic ...

HD 45166 is believed to have the strongest magnetic field ever found in a massive star. Credit: ESO / L. Calçada illustration Astronomers have been studying a weird old star in deep space that is ...

At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.

When the roiling nuclear fusion inside of a star begins to die — gravity crushing into the star’s waning fuel-store of hydrogen atoms, fusing them into heavier helium nuclei — the universe usually ...

In the vastness of the known universe, few things are more wondrous than a magnetar. These stars are deceptively pint-sized; they squeeze multiple suns’ worth of mass into an orb no bigger than a city ...

Magnetars are some of the most extreme objects we know about, with magnetic fields so strong that chemistry becomes impossible in their vicinity. They’re neutron stars with a superfluid interior that ...

Astronomers have mapped themagnetic field inside DR21, one of the most active star-forming regions near the Sun, and found ...

After a decade of silence, one of the most powerful magnets in the universe suddenly burst back to life in late 2018. The reawakening of this “magnetar”, a city-sized star named XTE J1810-197 born ...
