Astronomers have captured the clearest picture yet of how massive stars are born, revealing a dramatic interplay between ...

M87* is a supermassive black hole in a galaxy 55 million light-years away with a mass around 6.5 billion times the mass of ...

Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

NOAA's GOES-16 satellite captured the sun blast a "huge rush of mass" that warped the magnetic field, according to the ...

Spirals of solar wind can spin off larger solar eruptions and disrupt Earth's magnetic field, yet they are too difficult to ...

The Sun’s poles may hold answers to long-standing mysteries about magnetic cycles, solar wind, and space weather. The polar regions of the Sun remain one of the least explored areas in solar science.

Space weather forecasting is decades behind Earth’s meteorology. Learn what makes auroras so unpredictable—and the real-time ...

When the sun reaches its period of peak activity, known as solar maximum, our star's magentic field will suddenly reverse. But why does it happen, and will it impact Earth? When you purchase through ...

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...
