A new, expansive view of the Milky Way reveals our galaxy in unprecedented radio color

Astronomers from the International Centre of Radio Astronomy Research (ICRAR) have created the largest low-frequency radio color image of the Milky Way ever assembled. This spectacular new image captures the Southern Hemisphere view of our Milky Way galaxy, revealing it across a wide range of radio wavelengths, the colors of radio light.

Machine learning enables real-time analysis of iron oxide thin film growth in reactive magnetron sputtering

Researchers at University of Tsukuba have developed a technology for real-time estimation of the valence state and growth rate of iron oxide thin films during their formation. This novel technology was realized by analyzing the full-wavelength data of plasma emission spectra generated during reactive sputtering using machine learning. It is expected to enable high-precision control of the film deposition process.

The Red Spider Nebula, caught by Webb

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a cosmic creepy-crawly called NGC 6537—the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), Webb has revealed never-before-seen details in this picturesque planetary nebula with a rich backdrop of thousands of stars.

Young sun-like star’s dual-temperature plasma ejections offer clues to early planetary environments

Astronomers have used simultaneous ground-based and space-based observations to measure the temperature and velocity of gas ejected from a young sun-like star. The result showed a two-component ejection consisting of a hot fast component followed by a slower, cooler component. This result is important for understanding how young stars affect their surrounding environment where planets and life may first be forming, and by extension provides insights into the early days of the solar system, Earth, and life on Earth.

Gravitational wave events hint at ‘second-generation’ black holes

In a paper published in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of 2024 with unusual black hole spins. This observation adds an important new piece to our understanding of the most elusive phenomena in the universe.

Astronomers discover end-dominated collapse and hub-filament system in G53 star-forming region

Meng Dezhao, a Ph.D. student from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, together with his collaborators, has conducted a systematic study of the filamentary structure within the G53 molecular cloud. By combining multi-wavelength observations and simulations, they revealed for the first time that the filament is undergoing an “end-dominated collapse” (EDC), a process that is driving star formation. The paper is published in Astronomy & Astrophysics.

The cosmic microwave background is a wall of light—here’s how we might see beyond it

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of galaxies and supermassive black holes. But all of it is invisible to us.

Mirrorless laser: Physicists propose a new light source

A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical Review Letters, shows that quantum emitters spaced at subwavelength distances can constructively synchronize their photon emission to produce a bright, very narrow-band light beam, even in the absence of any optical cavity.
