Haunting Underwater Voice Remains Mystery 25 Years Later (Listen)
And one unknown occurrence has remained unanswered for 25 years.
Back in 1991, the National Oceanic and Atmospheric Administration captured an underwater sound off the Pacific Ocean, near the equator, eerily resembling that of a woman. As such, they named the phenomenon 'Julia.' And still, they've been scratching their heads as to what may have caused the anomalous noise. Hear it below.
Of course, online, conspiracy theorists have their ideas about what the sound may be. Like on Reddit, where some users commented and cautioned:
'So T-Rex didn't go extinct. He moved into the ocean to escape the heat from the apocalypse and is now a fish. Got it.'
'This is terrifying.... It's why you'll never find my ass out on a cruise ship. No thank you.'
'What could be causing that? Could it be something similar to the big blip, or like an under water eruption?'
'RELEASE THE KRAKEN!'In reality, the experts at NOAA do have a pretty distinct idea of what the mysterious sound may be. They believe it was the sound of an iceberg grounding on the seafloor. NOAA continued:
'This sound was recorded on March 1, 1999 on the eastern equatorial Pacific autonomous hydrophone array. The most likely source of the sound formerly known as 'Julia' is a large iceberg that has run aground off Antarctica. Due to the uncertainty of the arrival azimuth, the point of origin could be between Bransfield Straits and Cape Adare with an origin time of 1999 JD60 21:05GMT.'
Or, just maybe, there's more secrets in the ocean's depths that we've yet to discover.Haunting Underwater Voice Remains Mystery 25 Years Later (Listen) first appeared on Surfer on Aug 4, 2025

Geomagnetic storm may trigger northern lights this week. Will you be able to see them in Illinois?
A geomagnetic storm is expected to erupt on Earth this week, possibly triggering an appearance of the northern lights, also known as the aurora borealis, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. But will the lights be visible in Illinois? And when should you head outside to take a look? Here's what we know. What are the northern lights? The auroras are a natural light display in Earth's sky that are famously best seen in high-latitude regions of the Northern and Southern hemispheres. The phenomenon is caused when electrically charged particles from space enter Earth's atmosphere and collide with molecules and gases like oxygen and nitrogen, causing the atmospheric particles to gain energy. To return to their normal state, the particles release that energy in the form of light, according to the University of Alaska at Fairbanks Geophysical Institute website, which tracks the phenomenon. As auroras form, Earth's magnetic field redirects the particles toward the poles through a process that produces a stunning display of rays, spirals and flickers that have fascinated humans for millennia. Whether hues of green, red, blue and even pink dance about in the sky depends on the altitude where the collisions occur, as well as the composition and density of the atmosphere at the time. When will northern lights be visible? Even though conditions are prime for more impending aurora shows, experts have long struggled to accurately forecast exactly when and where the phenomenon will ever occur. Even the best predictions can accurately be made only a few days or even hours in advance. But the aurora is forecast to appear on Thursday, Aug. 7. As a rule of thumb, if the weather is clear, the best aurora is usually visible within an hour or two of midnight, according to NOAA. And if it looks as if the northern lights will flare up near you, you should get away from cities and travel to dark locations free from light pollution so you can best see them. The agency also maintains an aurora dashboard that should help skygazers track the phenomenon. NOAA's 30-minute aurora forecast may be particularly useful for regular updates on viewing opportunities. Where could auroras be visible? For most of the time, auroras are best seen around the magnetic poles of the Northern and Southern hemispheres in Europe, Asia and North America. In the U.S., Alaska is well known to have the best viewing opportunities for the northern lights. But a geomagnetic storm tracked by the NOAA is expected to make the auroras visible farther from the poles. The geomagnetic activity detected by NOAA's Space Weather Prediction Center has a Kp index of 6 on Thursday, Aug. 7, meaning the northern lights will be active and brighter further from the poles, according to the agency. "At this geomagnetic activity level, it might be possible to see the aurora from the northern edge of the United States," NOAA says on its website. More to see: Sturgeon Moon coming this week. Will skies be clear? When to view it in Illinois Will northern lights be visible in Illinois? Illinois is one of the southernmost locations where you may be able to see the aurora on the northern horizon. Aurora borealis may appear again on Friday The geomagentic storm will be less powerful Friday, Aug. 8, but is forecast to still be strong enough to trigger the northern lights once again across the northern U.S. By then, though, NOAA predicts the KP index will be downgraded to a 5, which still means the auroras are still bright further than usual from the poles. "If you are in the right place, these aurora can be quite pleasing to look at," according to NOAA's description of of 5-rating on the KP scale. Will skies be clear in Illinois during northern lights? Central Illinois will see scattered showers and thunderstorms on Thursday evening, mainly before 8 p.m., before skies turn cloudy, with a low around 72 degrees, according to the National Weather Service. Skies are forecast to be mostly clear on Friday night with a low around 73 degrees. Chicago will be similar, with a 50 percent chance of showers and thunderstorms on Thursday evening, mainly after 8pm, and a low around 73 degrees with clouds. Friday night will be mostly clear in the city, with a low around 76. This article originally appeared on Journal Star: Will aurora borealis be visible in Illinois?

Will we see the northern lights in Oklahoma tonight? See aurora forecast
When experienced stargazers in the continental United States hear the words, "geomagnetic storm," likely one question comes to mind: Are we getting some northern lights? In this case, the answer is yes, but it may depend on where you live. An explosion on the sun's outermost atmosphere of charged particles, known as a coronal mass ejection, has been hurtling toward Earth since Tuesday, Aug. 5, according to the National Oceanic and Atmospheric Administration. The agency's Space Weather Prediction Center has since been tracking the ejection, which it said has the potential to soon trigger a geomagnetic storm on Earth. What does that mean for skywatchers? Well, the particles flowing from the sun could interact with our planet's magnetosphere in ways that trigger the northern lights, also known as the aurora borealis. For the next two nights, the luminous green and red glow of the auroras may be more widely visible than is typical in up to 18 states in the U.S. Here's everything to know about the solar storm, as well as where and when to see the northern lights it could produce in the U.S. Northern Lights: The sun is spewing massive solar flares toward Earth Could geomagnetic storm disrupt communications on Earth? Weaker solar activity won't be noticeable here on Earth. But a geomagnetic storm with enough energy output has the potential to disrupt satellites, communications systems, and even ground-based technologies like power grids if directed at our planet. In extreme cases, powerful solar events even pose risks to spacecraft and astronauts, NASA says. About a year ago, in May 2024, a historically powerful geomagnetic storm was responsible for some reports of power grid irregularities and interference with GPS signals – even farming equipment. On the bright side, it also unleashed spectacular views of the northern lights in parts of the country where auroras are not often visible. In this case, a rapid, intense flash of electromagnetic energy ranks as a G1-G2 on NOAA's scale, indicating a minor-moderate geomagnetic storm that could cause "manageable effects to some technological infrastructure," the agency stated. A moderate geomagnetic storm is also strong enough to unleash views of the northern lights, also known as auroras, in some northern and upper midwest states. What are the northern lights?

In the U.S., the auroras will be visible Thursday to at least the northern parts of the following states: Washington Idaho Montana North Dakota South Dakota Minnesota Wisconisn Michigan A thin red "viewline" representing the southern-most locations from which you may see the aurora on the northern horizon extends to: Oregon Wyoming Nebraska Iowa Illinois Indiana New York Vermont New Hampshire Maine Will we see the northern lights in Oklahoma? It's possible, though unlikely this time. The best chance of seeing auroras late at night is to look north between 9 p.m. and 6 a.m. local time, and away from city lights. This far south, the lights are best seen with a camera, even the one that comes equipped with your smartphone. Although some maps and forecasts have predicted low visibility in southern states, some Oklahomans have still documented nights throughout the summer when they saw the lights in the late-night hours.

Scientists Think They Have Found a Brand-New Mineral on Mars
Scientists have a fairly good idea of what Mars' surface looks like. But exactly what that surface is made up of is more of a mystery. Now, scientists believe they have discovered an entirely new mineral on Mars from an unusual layer of iron sulfate with a distinct spectral signature. In a Nature Communications paper published on August 5, astrobiologists led by Janice Bishop at the SETI Institute describe the discovery of an unusual ferric hydroxysulfate compound around Valles Marineris, a vast chasm that sits along Mars' equator. It's an area that researchers suspect once flowed with water, and the new mineral's discovery could offer tantalizing clues as to how and what natural forces sculpted the planet's surface—and whether life once thrived on Mars. Sulfur, an element common to both Mars and Earth, often combines with other elements to form minerals in the form of sulfates. These minerals dissolve easily in water, but unlike Earth, Mars has persistently dry weather, meaning that sulfates may have remained on the surface since the planet lost its water. Studying these minerals, therefore, would uncover important information about Mars' early history. The researchers investigated sulfate-rich areas near Valles Marineris, paying special attention to regions that 'included mysterious spectral bands seen from orbital data, as well as layered sulfates and intriguing geology,' explained Bishop in a statement. In one area, they found layered deposits of polyhydrated sulfates, with monohydrated and ferric hydroxysulfates underneath. They tried to recreate these in the lab, finding that the ferric hydroxysulfate seen on Mars could only have formed in the presence of oxygen and that the reaction needed to produce the compound produces water. Further, this could only have happened at high temperatures, the researchers said, suggesting the sulfates formed from volcanic activity. What's more, its structure and thermal properties suggest it is a totally new mineral. 'The material formed in these lab experiments is likely a new mineral due to its unique crystal structure and thermal stability,' Bishop said. 'However, scientists must also find it on Earth to officially recognize it as a new mineral.'
