Previously unknown isotope of uranium discovered

A team of nuclear physicists affiliated with multiple institutions in Japan, working with a colleague from Korea, has discovered a previously unknown uranium isotope with atomic number 92 and mass 241. In their study, reported ...

Uranium reveals its true nature

Most people are familiar with uranium as a fuel for nuclear power plants. And while that's the most common application, this element is also used in many other fields, such as dyes, medical devices, and weapons. Scientists ...

Riding a laser to Mars

Could a laser send a spacecraft to Mars? That's a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber ...

NASA's Webb captures an ethereal view of NGC 346

Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth—NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely ...

Researchers discover a new type of matter inside neutron stars

A Finnish research group has found strong evidence for the presence of exotic quark matter inside the cores of the largest neutron stars in existence. They reached this conclusion by combining recent results from theoretical ...

Giant laser from 'Star Trek' to be tested in fusion breakthrough

The breakthrough came in an impossibly small slice of time, less than it takes a beam of light to move an inch. In that tiny moment, nuclear fusion as an energy source went from far-away dream to reality. The world is now ...
