Highly charged ions are a common form of matter in the cosmos, where they are found, for example, in the sun or other stars. They are so called because they have lost many electrons and therefore have a high positive charge. This is why the outermost electrons are more strongly bound to the atomic nucleus than in neutral or weakly charged atoms. For this reason, highly charged ions react less st

From the window of a NASA Gulfstream III research aircraft, Alaska looks like a pristine wilderness untouched by humans. The land is covered in lush, green vegetation and dotted with bright blue lakes. Snow-capped mountains reach toward the sky, and chocolate milk-colored rivers snake across the landscape. The obvious signs of human activity - cities, roads, infrastructure - are hard to spot.

Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way. Their findings are published in the Monthly Notices of the Royal Astronomical Society, which conclude that a faint white dwarf located 90 light years from Earth, as

Iran announced Saturday the successful test flight of a rocket capable of propelling satellites into space, three months after launching a satellite with the help of Russia.
The United States has repeatedly voiced concern that such launches could boost Iran's ballistic missile technology, extending to the potential delivery of nuclear warheads.
