A massive hole some 62 times wider than the Earth has opened up in the Sun's atmosphere—and it could lead to aurora over the U.S. NASA captured ... when magnetic field lines instead grow strong ...

When the solar energetic particles (SEPs) from these eruptions reach Earth, they pose a significant radiation hazard to satellites, aircraft, and humans. The powerful solar storms observed this year, ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

Farther out in the tail, the lines of Earth's magnetic field have been stretched and warped into something much messier. Physicists didn't think chorus waves could form amid the stretched-out mess ...

interacting with Earth’s magnetic field – they’re not sure what causes their unique movements. Specifically, researchers at NASA want to understand why some auroras flicker, others pulsate ...

Today, those NASA missions would be a centennial extension to continue building, exploring the science behind the northern lights and more generally to get at Earth's magnetic field and the ...

Scientists attribute auroras to solar flares interacting with Earth’s magnetic field. However, the cause of their different movements remains unclear. NASA has identified two types of auroras ...

A recently released animation shows a new look at a large asteroid that has a small, but significant, chance of impacting planet Earth in seven years. The animation, provided by the NASA-funded ...

What is the 'alien' that has been found near the South Pole? NASA is keeping a close watch on three asteroids making near-Earth approaches today. One of them, named 2025 CF, will pass within just ...

Currently, no other known large asteroids have an impact probability above 1%,” said NASA in a release. While there’s still a nearly 99 percent chance that 2024 YR4 won’t impact Earth ...
