Multiple coronal mass ejections head for Earth, promising moderate geomagnetic storms that could push the aurora borealis unusually far south this weekend. A powerful X1.1 solar flare erupted on June 30, setting off a rapid series of M‑class eruptions...

China’s massive high-altitude solar farms have triggered an unexpected ecological transformation beneath the panels, according to new research findings. Large-scale solar installations are often criticized for their potential impact on local...

A moderate geomagnetic storm may bring visible northern lights to parts of the northern US and Canada this weekend. A new NOAA outlook points to a rare summer opportunity for millions of people across northern U.S. states and Canada to glimpse the...

that formed a tail oriented away from the Sun. This process is completely governed by solar radiation pressure and the solar wind. Both the shape and intensity of the tail match theoretical models describing the behavior of cometary nuclei. If the...

the material reaches the dayside magnetopause, sunlight would ionize it, forming a plasma cloud that interacts with the solar wind and dissipates a portion of its energy. Computer simulations indicate that such a system could cut the intensity of the...

a glowing coma (a cloud of gas and dust) and a tail that always points away from the Sun due to solar radiation and solar wind. What is a comet’s structure? A comet consists of three main parts: Nucleus: The solid, icy core. Coma: A nebulous cloud...

A fast-moving solar wind stream could bring a vibrant display of the northern lights to parts of the United States this week. Find out if you can see them. Skywatchers across the northern United States are on alert as a high-speed stream of solar wind...

A soft X-ray flare in the galaxy NGC 3783 produced a rare, ultrafast outflow traveling at nearly one-fifth the speed of light, providing an unprecedented look at how supermassive black holes release energy into space. At the heart of the distant galaxy...

the boundary of our magnetosphere—is heavily dictated by seasonal shifts and the fluctuating magnetic orientation of the solar wind. Led by Lauri Holappa of the University of Oulu in Finland, the research team utilized advanced computer simulations to...

magnetic shield. The findings, reported in Nature Communications, show that crustal magnetic fields can interact with the solar wind in a way that mirrors Earth’s well‑known Dungey cycle. Magnetic reconnection on a planet without a global field For...

CME’s speed, magnetic orientation, or arrival time can shift the eventual intensity. Scientists will keep monitoring the solar wind throughout the weekend, and any unexpected strengthening could push the aurora farther south than initially forecast....

Blue Origin has unveiled a 20-meter lunar solar tower designed to provide over 10 kilowatts of power for future operations near the Moon’s south pole. Blue Origin has unveiled plans for a towering lunar solar array, a 20-meter structure designed to...

New JWST observations reveal how shifting winds in young solar systems may strip away the essential gas required to build planets. New data from the James Webb Space Telescope (JWST) is reshaping our understanding of how infant planetary systems shed...

scientific mission. A key target is Mercury’s exosphere, an incredibly thin layer of gas that is constantly bombarded by solar wind and influenced by surface geology. Scientists intend to “taste” these gases to determine their origins and how they...

New calculations show Earth could avoid being swallowed by the Sun’s red‑giant phase, possibly moving to a wider orbit around the resulting white dwarf. In roughly five billion years the Sun will deplete the hydrogen at its core, swell into a red giant...

of the asteroid’s crust. Such findings could illuminate how the object arrived at its current orbit and whether the solar wind has altered its surface over time. Zhang’s earlier analysis underscored the significance of Kamoʻoalewa’s atypical trajectory,...

September 8, 2026 Decoding the Chemistry of Cosmic Light Auroral displays are the visual manifestation of solar wind—streams of charged particles ejected by the Sun—interacting with Earth’s magnetosphere. As these particles are funneled toward the polar...
