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.

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 ...

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 ...

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

Scientists found that carbon enabled Earth’s core to solidify. Without it, the inner core may not exist. A team of scientists ...

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

An illustration of the sun's magnetic fields overlaid on an image of the sun captured by NASA's Solar Dynamics Observatory in 2016. NASA / SDO / AIA / LMSAL The sun’s magnetic field could form much ...

However, our understanding of planetary magnetic fields is limited to the eight planets in our solar system, as we haven't yet accrued much data on the magnetic fields of exoplanets. That could be ...

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 ...
