Physicists have measured the temperature of quark-gluon plasma, a state of matter from moments after the Big Bang, reaching trillions of Kelvin, providing new insights into the early universe's conditions and advancing understanding of matter under extreme temperatures.
Researchers have directly measured the temperature of superheated gold at around 19,000 kelvins using ultrafast X-ray scattering, challenging the long-held belief that the entropy catastrophe limits the superheating of solids, and opening new avenues for studying extreme states of matter.
Physicists have successfully superheated solid gold to over 33,740°F without melting it by using ultra-fast laser heating and real-time X-ray probes, challenging previous assumptions about the maximum temperature solids can withstand before melting, and providing new insights into high-energy states relevant to planetary interiors and fusion research.
Scientists used ultrafast high-intensity lasers and X-ray pulses to superheat gold to 14 times its melting point without melting, challenging previous theories about solid stability and demonstrating a new method for measuring extreme temperatures in hot systems, reaching up to 19,000 Kelvin.
Scientists at SLAC used giant lasers and X-ray techniques to heat gold to unprecedented temperatures, surpassing the traditional superheating limit and challenging established physics models, with potential applications in spaceflight, astrophysics, and nuclear chemistry.
Researchers at the National Institute of Standards and Technology (NIST) have developed a new method to interrogate photonic thermometers using dual frequency comb technology, allowing for faster and more accurate temperature measurements. By combining two optical frequency combs, the researchers were able to compress the optical information into the radio frequency regime, making it easier to read out temperature data. This approach has the potential to revolutionize temperature measurement and enable the integration of photonic sensors into various structures for real-time monitoring. The researchers are now working towards commercializing this technology.
India's Chandrayaan-3 mission has successfully landed near the lunar south pole, becoming the fourth nation to land on the Moon. The Vikram lander has taken the first measurements of the lunar soil's temperature at various depths, while the Pragyan rover explores the surface. The mission aims to remain operational for 14 Earth days and conduct detailed observations of the lunar south pole.
The upcoming Google Pixel 8 Pro is rumored to feature a dedicated IR thermometer sensor located on the rear camera housing, which can measure the temperature of external objects and a person's skin. The sensor requires access to bare skin and will not work correctly with any obstructions. While this feature is not new, it could find some niche uses as an external IR thermometer or be repurposed for other applications.
The James Webb Space Telescope has measured the temperature of the rocky exoplanet TRAPPIST-1 b, indicating that its dayside has a temperature of about 500 kelvins (roughly 230°C) and suggesting that it has no significant atmosphere. This is the first detection of any form of light emitted by an exoplanet as small and as cool as the rocky planets in our own solar system. The result marks an important step in determining whether planets orbiting small active stars like TRAPPIST-1 can sustain atmospheres needed to support life.
