A trio of triangle teasers

The first 'negative triangularity' nuclear reactor has achieved first plasma. What else will it achieve?

Scientific American columnist Martin Gardner started a long mathematical conversation that continues today

The millimeter-long machine moves autonomously when exposed to light or heat.

Built by MIT researchers, the Plasma Science Experiment aboard the Voyager 2 spacecraft took measurements for the last 47 years and 15 billion miles, before shutting down on Sept. 26.

In a dazzling fusion milestone, a magnetic mirror achieved first plasma. A major new player has entered the race toward endless energy.

China's HL-3 tokamak generated a magnetic field, marking a major milestone in fusion research. It places China among the leaders in nuclear fusion technology.

NASA's Chandra X-ray Observatory has thoroughly explored the 3C 58 supernova remnant. NASA's Chandra X-ray Observatory has thoroughly explored the 3C 58 supernova remnant, focusing mainly on its neutron star, PSR J0205+6449.

The experimental fusion reactor sustained temperatures of 212 million degrees Fahrenheit for a record-breaking 48 seconds.

A British startup has set a new pressure record using the world's strongest pulsed power machine, as it looks to forge a cheaper, faster path to fusion energy. First Light Fusion ...

Rotating detonation engines developed by NASA and others could spark a rocketry revolution

A comprehensive study of high-temperature superconducting magnets built by MIT and Commonwealth Fusion Systems confirms they meet requirements for an economic, compact fusion power plant.

When it comes to fusion, hot plasma is only half the battle — tokamaks need to also contain that plasma for long stretches.

China has built the most powerful thermoacoustic Stirling generator. The prototype delivered a groundbreaking 102 kilowatts of power from a heat source of 530

Since the 1960s there has been plenty of evidence to support the existence of dark matter through astrophysical and cosmological observations, and at this point we're very confident that it exists. The question remains, though: what is dark matter actually made of?

The telescopes will team up to assist NASA's Juno spacecraft the next time it flies by Io, our solar system's most volcanic body.

For a half century, mathematicians have tried to define the exact circumstances under which a black hole is destined to exist. A new proof shows how a cube can help answer the question.

Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to…

As NASA's desire for planned crewed missions to Mars becomes reality, establishing safe human settlements for life off-Earth is one of the agency's most urgent tasks.
