Watch as a vibrant aurora dances across the night sky
About 20 U.S. states caught a glimpse of the northern lights, according to NOAA.
Americans in some northern U.S. states may have another opportunity to catch a glimpse of the night sky's greatest spectacle.
The northern lights are slated to be visible in states from Idaho to New York on the night of Saturday, June 14 as a geomagnetic storm watch was issued, according to the National Oceanic and Atmospheric Administration. The agency's Space Weather Prediction Center classified the geomagnetic storm as a G2, the second lowest level on its G scale that sorts intensity from G1 (least) to G5 (most).
The stunning natural phenomenon, formally known as aurora borealis, is expected to be visible over some northern-tier and upper Midwest states, according to the NOAA.
Hopeful viewers may have a smaller window to see the lights because of longer daylight hours as the summer solstice arrives between June 20 and 21.
Earlier this month, people in around 16 different states were blessed with the opportunity to see the swirling green, red and purple lights.
What are the northern lights?
Aurora borealis, commonly known as the northern lights, are colorful ribbons of light that weave across Earth's northern or southern polar regions, according to NASA.
Geomagnetic storms are caused by solar activity like solar flares or coronal mass ejections. The solar wind moves energetic charged particles from these events away from the sun to produce the northern lights.
Can you see northern lights with the naked eye?
Northern lights can be safely viewed without a telescope or microscope. The visibility of the aurora depends on multiple factors, including location, weather, time of night and the level of geomagnetic activity present.

Experts issue warning on ocean phenomenon that could impact hurricane season: 'It's been notable over the month'
Despite rising sea surface temperatures across the globe, the emergence of an Atlantic Niña has brought cooler waters to portions of the Atlantic. However, experts believe that its potential effects may be short-lived. What's happening? An Atlantic Niña, characterized by persistent cool surface temperatures in the tropical Atlantic, typically lasts for at least two consecutive three-month periods. An Atlantic Niña can cool the eastern equatorial Atlantic Ocean by over one degree Fahrenheit below normal. In August 2024, a report from the National Oceanic and Atmospheric Administration first made note of the potential for the development of an Atlantic Niña. Unlike El Niño and La Niña, which are based in the Pacific Ocean, Atlantic Niñas are often considered to have less impact on overall weather patterns. However, the cooler surface temperatures in the Atlantic can play a large role in determining the viability of tropical waves coming off the coast of West Africa. Carl Schreck, a senior research scholar with the North Carolina Institute for Climate Studies at North Carolina State University, explained the inner workings of the weather phenomenon. "An Atlantic Niña is cooler than normal sea surface temperatures in the Gulf of Guinea, which tends to weaken the monsoon and easterly waves over West Africa," Schreck told the Cayman Compass. "The strength of that monsoon is a key predictor of hurricane activity, so an Atlantic Niña could reduce activity." Why is an Atlantic Niña important? Although an Atlantic Niña may seem to be good news for the 2025 Atlantic hurricane season, it appears that the effects will soon dissipate. "It's been notable over the month," said Ryan Truchelut, president of Weather Tiger. "But I don't think it will continue very long. It just doesn't have the kind of persistence that the Pacific events do." According to Truchelut, the writing is already on the wall. "We're already seeing weaker trade winds, and those waters are warming up very quickly. Also, if you go down 25 or 50 metres, it's still warmer than normal." "If the Atlantic Niña was going to persist longer, the cold water would likely go down a lot further. So, I think that this will turn around probably within the next month," Truchelut added. With the Atlantic Niña likely on its way out the door, the waters will eventually warm back up, providing fuel for tropical systems to develop. As warm ocean water evaporates, it creates moisture in the air. As this moist air rises and cools, water vapor condenses into clouds and potentially storms. What's being done about the upcoming hurricane season? Because of the potential for such warm ocean waters, many tropical waves that develop into storms have a higher probability of bringing stronger winds and heavier rainfall. This is why, despite the slow start to the 2025 Atlantic hurricane season, many experts are still forecasting a highly active summer. Do you think your city has good air quality? Definitely Somewhat Depends on the time of year Not at all Click your choice to see results and speak your mind. The NOAA is predicting that at least 17 named storms will develop throughout the hurricane season, with up to five of those storms becoming major hurricanes. It's not too late to help reverse the rising global temperatures and the wide array of climate issues that come with them. By reducing our reliance on fossil fuel consumption and turning to renewable energy sources, we may be able to lower our rate of carbon pollution and work toward a cooler and calmer future.

Scientist issue warning about concerning phenomenon ahead of upcoming winter season: 'Keeps the surface cooler'
Experts have projected record low levels of Arctic sea ice for the coming winter, which counterintuitively could mean frigid conditions for the United States, Canada, and Europe, Severe Weather Europe reported. What's happening? The Arctic ice melting season typically runs from March to September, and already scientists have observed record low levels of ice for the time of year, per Severe Weather Europe. Unlike the ice sheets of Antarctica and Greenland, Arctic sea ice does not sit atop a land mass. Instead, it floats in the ocean, meaning that when it melts, it does not contribute to sea-level rise in the same manner as melting land ice. However, Arctic sea ice, or a lack thereof, still has a dramatic impact on the world's oceans and climate. Why is Arctic sea ice important? Arctic sea ice is much more reflective than ocean water, which means that it absorbs much less heat from the sun, according to the National Snow and Ice Data Center. "The ocean reflects only 6% of the incoming solar radiation and absorbs the rest, while sea ice reflects 50 to 70% of the incoming energy," the NSIDC explained. "The sea ice absorbs less solar energy and keeps the surface cooler." Thus, less sea ice results in warmer oceans, and warmer oceans threaten vital ecosystems, alter currents, and change weather patterns. They also contribute to sea-level rise because water expands as it warms, according to NOAA. Less Arctic sea ice during the winter months also means higher temperatures in the atmosphere, which can weaken or even collapse the polar vortex, according to Severe Weather Europe. The condition of the polar vortex influences everyday weather around the globe. "A strong/stable polar vortex usually means strong polar circulation and jet stream," Severe Weather Europe explained. "This locks the colder air into the Arctic Circle, creating milder conditions for most of the United States and warmer-than-normal conditions over southern Canada." Do you think our power grid needs to be upgraded? Definitely Only in some states Not really I'm not sure Click your choice to see results and speak your mind. A weaker and more unstable polar vortex, on the other hand, weakens the jet stream, which allows cold air to escape from the Arctic region and descend upon the U.S. and Canada. What's being done about the loss of Arctic sea ice? The loss of Arctic ice is just one of the many ways in which rising global temperatures are transforming the world, with complicated and unpredictable results. In order to reduce the rate of Arctic sea ice loss and avoid the most severe impacts of rising global temperatures, it is necessary to significantly reduce the amount of heat-trapping pollution entering the atmosphere. While the problem may seem so huge as to be insurmountable, there are things large and small that everyone can do to help make a difference. From making your voice heard and pushing for political action to taking public transit, driving an electric vehicle, and installing solar panels on your home, there are plenty of ways for anyone to contribute. Pairing solar panels with a home battery system can drop your energy bills to practically nothing while also making your home more resilient in the event of power outages.

Magnitude 7.3 earthquake recorded off Alaska coast; tsunami warning issued
A 7.3 magnitude earthquake was recorded off the Alaska Peninsula on Wednesday afternoon, July 16. The U.S. Geological Survey recorded the earthquake off Sand Point, Popof Island, which is located in the center of the Alaska Peninsula, at just after 12:30 p.m. local time. The National Oceanic and Atmospheric Administration (NOAA) issued a tsunami warning for the majority of the Alaska Peninsula, spanning up into the southern-most part of Alaska's mainland toward Anchorage. A major earthquake, capable of causing "serious damage," is considered having a magnitude between 7.0-7.9, according to Michigan Technological University. Only about 10-15 earthquakes of this caliber are reported each year. This is a developing story. This article originally appeared on USA TODAY: Earthquake off Alaska coast triggers tsunami warning
