Rare high-resolution observations of a flare-prolific solar active region

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR solar telescope in Tenerife, researchers recorded the explosive activity of the sun’s most energetic sunspot group of 2025, revealing twisted magnetic structures and the early stages of flare […]

Astronomers unveil 400 sibling star clusters in the Milky Way

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide insight into how stars form within giant molecular clouds, making them important indicators of star formation and cluster evolution.

Meteorite samples are time capsules from the early solar system

When a meteor streaks across the sky, it’s not just beautiful. It’s nature’s way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed.

Astronomers capture an exceptional gamma-ray flare from a blazar

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection of an exceptional gamma-ray flare from this object.

Red spider nebula photo taken by Webb

Using its Near-InfraRed Camera (NIRCam), NASA’s James Webb Space Telescope captured never-before-seen details of the Red Spider Nebula, a planetary nebula, in this image released on Oct. 26, 2025. NIRCam is Webb’s primary near-infrared imager, providing high-resolution imaging and spectroscopy for a wide variety of investigations.

Astronomers investigate nearby pulsar with radio telescopes

Using the Large Phased Array (LPA) and the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from Russia and China have observed a nearby pulsar designated PSR J1951+2837. The new observations, presented Nov. 18 on the pre-print server arXiv, deliver important insights into the nature of this pulsar.

Starquakes reveal red giant’s turbulent history and rapid spin in black hole system

Astronomers from the University of Hawaiʻi Institute for Astronomy (IfA) have uncovered the turbulent past of a distant red giant by listening to its celestial “song.” Subtle variations in the star’s brightness suggest that it potentially once collided and merged with another star, an explosive event that left it spinning rapidly. It now orbits a […]

When darkness shines: How dark stars could illuminate the early universe

Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be examples of dark stars. The concept of dark stars has existed for some time and could alter scientists’ understanding of how ordinary stars form. However, their name is somewhat misleading.

The DEVILS in the details: How the cosmic landscape impacts the galaxy lifecycle

A team of astronomers from the International Center for Radio Astronomy Research (ICRAR) has released new data from an extensive galaxy evolution survey that found a galaxy’s “neighborhood” plays a major role in how it changes over time. The data were published in Monthly Notices of the Royal Astronomical Society.

After nearly 100 years, scientists may have detected dark matter

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. Nearly 100 years later, NASA’s Fermi Gamma-ray Space Telescope may have provided direct evidence of dark matter, allowing the invisible matter to […]
