New insight into Earth’s magnetic field

New insight into Earth’s magnetic field

NASA's new observations of the Earth's magnetic field indicate that its foreshock region is capable of accelerating electrons to almost the speed of light. Earth's magnetic field deflects the incoming charged particles from the Sun. In regions outside…

How solar flares accelerate charged particles into super high speeds

How solar flares accelerate charged particles into super high speeds

Scientists have made another step toward determining how solar flares accelerate charged particles like electrons and protons to speeds of almost the order of light. The new capabilities of the National Science Foundation's Karl G. Jansky Very Large Array (VLA)…

Antiproton ring found around Earth

Antiproton ring found around Earth

Antiprotons appear to ring the Earth, confined by the planet's magnetic field lines. The antimatter, which may persist for minutes or hours before annihilating with normal matter, could in theory be used to fuel ultra-efficient rockets of the future.Charged particle

Gigantic jets of lightning in Earth’s upper atmosphere puzzle scientists

Gigantic jets of lightning in Earth’s upper atmosphere puzzle scientists

Mysterious and gigantic jets of lightning that shoot up to near the edge of space have now been observed in unprecedented detail, revealing just how much charge they pack and how they form. More than 50 miles (80 kilometers) above Earth's surface, extreme…
