The UK is not well prepared for a severe space weather event, despite some investment in developing forecasting capabilities. The government does not yet understand the full range of possible impacts and cascading effects well.
Stellar activity such as solar storms and plasma turbulence from a star near a transmitting planet can broaden otherwise ultra-narrow signals. That spreads the power of any such transmission across more frequencies, the institute's scientists say, which makes it more difficult to detect using traditional narrowband searches.
Recently, Anchorage, Alaska's largest city with nearly 400,000 residents, has just recorded its snowiest January on record. Tucked in between the mighty Cook Inlet and pushed right up against the Chugach Mountains, Anchorage sits in prime location for some serious snow totals. Moisture from pacific storms builds up over the inlet, and thanks to orographic lift caused by the mountains, forces that moisture to drop over Anchorage. Thanks to Alaska's northernly location, that moisture often falls in the form of snow.
He had flown in from Mar-a-Lago and, he told me, was there to observe. The next day, he watched as Åsa Rennermalm, a Rutgers University professor who studies polar regions, sat onstage with European foreign ministers and spoke out against cuts to U.S. science funding. "A leading US Arctic scientist is on stage absolutely ripping her country to the delight of the audience," Dans wrote on X. "Embarassing." He punctuated his post with an American-flag emoji.
Auroras are nature's most special light show: when charged particles from the sun hit our atmosphere, they can generate bright colors that dance across the night sky near the Earth's poles. Auroras can come in various forms, including bands, rays, patches and more. But why auroras form these patterns is less clear. Now, researchers say they've identified the battery that powers at least one kind of auroraaurora arcs.
Climate change which U.S. President Donald Trump calls the greatest con job ever perpetrated in the world is precisely what is driving the push to gain control of Greenland, an ambition openly declared by Trump. Human-caused global warming is reaching record levels in the Arctic region. This triggers ice melt, opening new shipping routes that major powers want to control, as well as theoretically easier access to the island's resources minerals and fossil fuels.
Gale-force winds and storms barrelled through northern Europe, claiming more lives, causing travel mayhem, shutting schools, and cutting power to hundreds of thousands in freezing temperatures. Some 50 flights were cancelled at London's Heathrow airport, affecting thousands of passengers. Air travel was disrupted across Europe from the Czech Republic to Moscow, where over 300 flights were cancelled at four airports serving the Russian capital.
Earlier this week, the Sun unleashed a powerful X-class solar flare, a major burst of electromagnetically charged particles that lit up the Earth's night sky as they entered our planet's atmosphere. The effect was stunning: a dazzling display of auroras reaching as far as southern California. Forecasters that it was one of the largest solar storms in decades, making for a particularly unique opportunity to watch the show unfold.
The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we sometimes picture, the sun's surface is made up of roiling plasma thrown about by twisting magnetic fields. When these fields snap, they can throw out huge bursts of energy and charged particles into spacea solar flare.
That seemingly paradoxical dynamic results from several factors. Foremost among them is the rebound of land beneath the Greenland Ice Sheet, a mile-thick body of glacial ice that covers 80 percent of the island and is being lost to melting at a rate of roughly 200 billion tons each year. As the ice sheet loses mass, the land beneath rises.
