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 […]

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), […]

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.

Spectral biosignatures of airborne microbes in planetary atmospheres

Could scientists find life in the clouds of exoplanet atmospheres? This is what a manuscripton the arXiv preprint server hopes to address as a team of researchers investigate how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds.

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, […]

Here Are Five Of The Oldest Cities On Earth

Some of these cities existed before written history, and before mankind existed on Earth, at least according to the Bible. But before religion, and before written history, ancient cultures around the world built massive cities, extremely old cities.

And when we talk about the oldest cities on Earth, we mean the oldest continuously inhabited […]

JWST observations discover large debris disk around nearby M dwarf

An international team of astronomers have employed the James Webb Space Telescope (JWST) to observe a nearby M-dwarf star known as TWA 20. As a result, they detected a large debris disk around this star. The finding was reported in a paper published October 23 on the arXiv pre-print server.
