4.6 Billion-Year-Old Stardust May Clues to the Life Cycle of Stars

Research into ancient grains of dust from space, known as presolar grains, are providing valuable insights into the life cycle of stars. These microscopic grains, which predate our solar system, have been found in primitive meteorites on Earth. Sachiko Amari, research Professor of Physics, Arts & Sciences at Washington University in St. Louis, US, writes for The Conversation, that researchers have identified these grains as remnants from stars that existed over 4.6 billion years ago.

In the study, scientists have identified an anomalous energy gap in electron-doped cuprates, which smoothly connects to the superconducting gap at optimal doping levels. This normal-state gap raises the prospect of engineering higher transition temperatures in n-type cuprates, comparable to those of p-type cuprates. These insights could pave the way for developing superconductors that function at more practical temperatures, significantly impacting various technologies, from quantum computing to energy transmission.

Understanding this phenomenon could be crucial for achieving room-temperature superconductivity. Most superconductors currently operate at very low temperatures. Type I superconductors have critical temperatures between 0.000325 K and 7.8 K, while high-temperature superconductors like cuprates function up to around 150 K (-123 degrees Celsius). The highest temperature superconductor discovered so far is lanthanum decahydride, which works up to 250 K (-23 degrees Celsius) under high pressure.

These advancements highlight the potential for higher temperature superconductors, which could transform industries by enabling more efficient energy transmission, advanced computing, and innovative transportation solutions.

South Africa's MeerKAT Telescope Reveals an Odd Radio Ring Near the Galactic Center

Astronomers have made a “serendipitous” discovery of a new radio-continuum ring-like object, nicknamed Kýklos, using the South African Radio Astronomy Observatory’s (SARAO) MeerKAT radio telescope in Northern Cape, South Africa. This object, resembling the recently discovered odd radio circles (ORCs), is located just six degrees from the Galactic plane and close to the Galactic center. Kýklos exhibits an atypical thermal radio-continuum spectrum, leading researchers to explore various formation scenarios. The most plausible explanation is that Kýklos is a circumstellar shell around an evolved massive star, possibly a Wolf-Rayet star - a type of star known for its unusual spectra, strong stellar winds and high luminosity.
