Potentially distinct structure in Kuiper belt discovered with help of clustering algorithm

A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the […]

Q&A: Euclid mission’s quest to reveal hidden patterns of cosmic evolution

The European Space Agency’s Euclid mission—designed to map the geometry of the dark universe with unprecedented precision—continues to deliver its first scientific insights. The Euclid Consortium has published a fresh set of seven scientific papers […]

NASA’s Roman could bring new waves of information on galaxy’s stars

A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope.This post was originally […]

Astronomers spot ‘first stars’ billions of years after they were supposed to die

Over the course of billions of years, the universe has steadily been evolving. Thanks to the expansion of the universe, we are able to “see” back in time to watch that evolution, almost from the […]

Chinese telescope captures 155 high-frequency bursts from fast radio burst 20240114A

Using the Tianma Radio Telescope (TMRT), researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences conducted 66 simultaneous dual‑frequency (2.25 GHz/8.60 GHz) observations of the fast radio burst FRB 20240114A over […]

Scientists get a first look at the innermost region of a white dwarf system

Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star is a type of white dwarf that exerts a powerful […]

LHAASO conducts all-sky search for exploding primordial black holes

Primordial black holes (PBHs) are black holes theorized to have formed shortly after the Big Bang. Compared to black holes emerging from collapsing stars, PBHs could have very different masses, ranging from very small to […]

Dusty star-forming galaxy at high redshift discovered

An international team of astronomers reports the discovery of a new dusty star-forming galaxy at high redshift. The newfound galaxy, designated AC-2168, was detected using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Northern Extended […]

Physicists and philosophers have long struggled to understand the nature of time: Here’s why

The nature of time has plagued thinkers for as long as we’ve tried to understand the world we live in. Intuitively, we know what time is, but try to explain it, and we end up […]

Webb reveals Apep’s four ‘spiraling’ dust shells shaped by Wolf-Rayet stars

NASA’s James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. […]
