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

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 ...

How do stars form? Scientists know that stars are born when huge clouds of cold gas in space collapse under their own gravity ...

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 ...

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 ...

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 ...

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 ...

Magnetars are the strongest magnets in the universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they form.
