High-resolution images show swirling magnetic structures covering much of the Sun’s surface, suggesting pervasive solar magnetism. A team of solar researchers has identified a previously unseen layer of activity on the Sun, documenting extensive...

a combined arrival window projected for July 5‑6. The Sun has really woken up over the past 48 hours, producing multiple solar flares (including an “X-class” event), across 4 different regions. Further large flares are likely in the coming days!...

Brief flashes of millimeter-wave light seen by the South Pole Telescope reveal magnetic activity in compact white dwarf systems close to the Galactic center, showing that these small stars can release energy in unexpected ways. The center of the Milky...

has survived massive solar events before, the direct correlation between these high-energy particle bursts and specific solar flares remains a subject of intense investigation. “According to the current state of research, extreme particle eruptions and...

A new burst of solar activity has researchers on alert. Experts explain what to expect when the solar storm arrives and why its exact impact remains unclear. Solar activity spiked on October 6, 2026, when an M1.4-class solar flare erupted from a...

snap and reconnect, releasing intense bursts of energy. This process, called magnetic reconnection, is known from: Solar flares in our own Sun. Magnetic storms in Earth’s magnetosphere. In NGC 3783, something similar appears to be happening much closer...

to locate the origins of energetic radio bursts associated with events such as coronal mass ejections and intense solar flares. These radio signatures are linked to streams of charged particles that can traverse the Solar System and interact with...

only flagged after they have begun. Importantly, the ability to forecast region emergence does not equate to predicting solar flares or coronal mass ejections, many of which never erupt despite the presence of an active region. Nonetheless, extending...

magnetic instabilities on the Sun, specifically originating from the complex region designated as sunspot 4524. While solar flares release electromagnetic radiation that reaches our planet in minutes, CMEs consist of massive clouds of plasma that travel...

a clear view of the structural integrity and intensity of incoming solar storms. These storms, which originate from solar flares, coronal mass ejections, and bursts of high-energy particles, have the potential to trigger geomagnetic activity that can...

Astronomers have uncovered a rare, decades-long flare from the Perseus Cluster’s central black hole, finally solving a mystery hidden in years of data. Astronomers tracking the behavior of a supermassive black hole at the heart of the Perseus Cluster...

NOAA-tracked solar flare may light up the U.S. with auroras, offering a rare chance to see the northern lights across several states. A pair of solar eruptions launched on July 26 and 27 could trigger a modest aurora that may be visible in the northern...

NASA’s Roman Space Telescope may spot distant black holes The Nancy Grace Roman Space Telescope is poised to revolutionize the hunt for distant black holes by capturing thousands of transient stellar disruptions across the cosmos. A study released...

A record-breaking gamma-ray burst from 2 billion light-years away has left a rare, measurable electrical signature in Earth’s upper atmosphere. A staggering burst of radiation from an exploding star, located nearly 2 billion light-years away, has...

A star shredded far from its galaxy’s center has revealed a massive black hole, challenging our understanding of how these giants roam through space. Astronomers have uncovered a massive black hole lurking 3,500 light-years away from the center of its...
