Astronomers spotted a red supergiant just before it exploded in a massive supernova
It was discovered just 130 days before exploding using two telescopes in Hawaii, allowing a team of experts to investigate it before it exploded in a massive supernova.
“This is a breakthrough in our understanding of what massive stars do moments before they die,” said Dr. Wynn Jacobson-Galán, the study’s lead author.
Light-Induced Superconductivity: A New Frontier in Quantum Physics
Researchers have developed methods to explore and utilize superconductivity in non-equilibrium states, such as those induced by laser pulses, at temperatures much higher than traditional superconductors operate.
This light-induced superconductivity has been shown to replicate crucial features like zero electrical resistance and expulsion of magnetic fields, suggesting potential applications in high-speed devices and extending superconductivity to ambient temperatures.
Superconductivity is a remarkable phenomenon that enables a material to carry an electrical current with zero loss. This collective quantum behavior is unique to certain conductors and only occurs at temperatures significantly below room level.
Ed Dwight: A space pioneer who finally became an astronaut
Ed Dwight could have been the only black astronaut in the 1960s – but politics got in the way. In 2024, at the age of 90, he finally got his chance to go into orbit.
Humanity has entered a new age of space tourism. For a minimum of $450,000 (£360,000), people with deep pockets can claim the title “astronaut” after a short sub-orbital flight to the edge of space and back and up to 10 minutes experiencing weightlessness above the Earth.
On these near-spaceflights, currently offered by Blue Origin and Virgin Galactic, there is usually one member of the crew whose name and story captures the headlines – and often a free ride.
