This study underscores the importance of precise temperature measurements in extreme states, a challenge that has historically hindered progress in high-energy physics and material science.

The innovative technique for measuring temperature at extreme conditions opens new avenues for manipulating material properties at high temperatures, potentially leading to technological advancements.

The research team developed a method to directly measure ion velocities and temperatures in warm dense matter, marking a significant step forward in understanding extreme physical states.

One of the researchers expressed surprise at the results, highlighting the unexpected nature of surpassing previous temperature limits for superheating.

Scientists have achieved a groundbreaking feat by using lasers to heat solid gold to over 14 times its melting temperature while preserving its crystalline structure, surpassing previous theoretical limits for superheating.

This research has significant implications across fields like spaceflight, astrophysics, and nuclear chemistry, by enhancing our understanding of hot, dense matter in extreme environments such as stars and fusion reactors.

The X-ray method used could also help simulate the effects of extreme heat and pressure on materials relevant to planetary science.

The study, published in Nature, reflects over a decade of work in high energy density physics, with implications for planetary physics and fusion energy, involving collaboration from several top institutions.

This experiment, published in Nature, directly measured the temperature of matter in extreme states, challenging the long-held belief that gold would reach an 'entropy catastrophe' and explode beyond 1,948°F (1,064°C).

The findings suggest that there may be no upper limit to superheating if materials are heated rapidly enough, raising questions about the true stability limits of superheated solids.

The research was led by scientists from SLAC and the University of Nevada, Reno, with collaboration from multiple prestigious institutions, supported by the National Nuclear Security Administration.

The new temperature measurement method, which uses ultrabright X-rays, could accelerate progress in nuclear fusion research by accurately determining melting points of materials used in extreme conditions.

The team, including students from various institutions, is continuing their work by measuring temperatures in hot compressed iron to better understand planetary interiors and high-energy-density environments.
