A picture snapped from the International Space Station (ISS) by NASA astronaut Nichole Ayers has captured a lesser-seen view of an extraordinary atmospheric phenomenon known as a red sprite.
The photo, taken from orbit during the night, shows a glowing bluish-purple halo with a vivid red column shooting upward into space.
"Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite," Ayers shared on X, formerly Twitter, on the evening of July 3, 2025. The image has gained over 2.7 million views on the social-media platform, amazing viewers from the ground.
A U.S. Air Force lieutenant colonel and combat-experienced fighter pilot, Ayers was selected as part of NASA's Artemis generation of astronauts.
Currently onboard the ISS as part of Expedition 73, Ayers and her fellow crew members are tasked with a number of scientific experiments, from environmental monitoring to observing human physiology.

What Are Red Sprites?
Red sprites, like the one in the picture above, are a form of upper-atmospheric lightning, occurring between 30 and 60 miles above Earth's surface.
Unlike the familiar bolts that crack down from clouds to the ground, sprites shoot upward into the mesosphere, often appearing red or pink, due to the interaction of nitrogen molecules with high-energy electrons.
These phenomena are part of a broader category called Transient Luminous Events.
Alongside red sprites, there are other examples of TLEs, including:
Blue Jets: Discharges that travel upward from thunderclouds to the stratosphere.
Elves: Expanding disk-shaped glowing lights triggered by lightening-generated electromagnetic pulses.
Gigantic Jets: Large electric discharges that span from the thunderstorm up to the ionosphere.
Although first captured in photos in the late 20th century, sprites were reported by pilots as early as the 1950s and are now frequently studied, thanks to advanced space-based cameras like those on the ISS.
In its own post on X, NASA added: "A view of lightning that's nothing like what we see on the ground: crew observations and instruments on the space station can help us better understand the behaviors of storms."
Newsweek reached out to NASA via email for comment.
Why These Photos Matter
Images like the one shared by Ayers are not just breathtaking, they are also scientifically valuable. Studying sprites helps scientists understand the electrical balance of the atmosphere, and even the potential impacts on communication technology and aviation.
Space-based observations are essential in documenting TLEs. Earth-based detection is limited by weather and geography, while views from the ISS offer a unique vantage point unobstructed by clouds or light pollution.

New Study Says Skip the Hot Dogs This Fourth of July
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. As Americans fire up their grills for the Fourth of July, a new study published in Nature Medicine says that there is no safe amount of hot dogs—or any processed meat—to consume. The study, led by Dr. Demewoz Haile of the University of Washington's Institute for Health Metrics and Evaluation, found that even small daily servings of processed meat significantly increase the risk of type 2 diabetes, colorectal cancer, and heart disease. The findings arrive just as Americans are expected to consume over 150 million hot dogs during the holiday weekend. Health experts are urging moderation, if not outright avoidance, of processed meats, sugary drinks, and trans fats. The study analyzed data from over 60 prior studies and employed a burden-of-proof methodology to evaluate the strength of the evidence. Hot dogs are ready for the 2025 Nathan's Famous Fourth of July hot dog eating competition at Coney Island in the Brooklyn borough of New York on July 4, 2025. Hot dogs are ready for the 2025 Nathan's Famous Fourth of July hot dog eating competition at Coney Island in the Brooklyn borough of New York on July 4, It Matters Hot dogs are a staple of July 4 celebrations, but this research contributes to a growing body of evidence linking processed meats to an increased risk of chronic disease. With diet-related illnesses already among the leading causes of death in the U.S., the study speaks to the need for more transparent communication about the risks of everyday foods that are deeply embedded in American culture. What To Know Eating just 50 grams of processed meat daily—the weight of a typical hot dog—is associated with an 11 percent higher risk of type 2 diabetes and a 7 percent higher risk of colorectal cancer. The study also found links between sugary drinks and ischemic heart disease and between trans fats and elevated cholesterol. Researchers concluded that there is no safe level of habitual consumption of processed meats, sugary drinks, or trans fats. The strongest associations were observed even at low levels of intake, suggesting that regular consumption—regardless of the amount—poses measurable health risks. The research pooled data from over 60 studies and applied a burden-of-proof risk function to assess the strength and consistency of the evidence. While observational, the study's scale and statistical rigor make its findings difficult to ignore. Dr. Nita Forouhi of the University of Cambridge, who was not involved in the study, said the findings support existing dietary guidelines to limit processed meat, per CNN. Other experts emphasized that occasional indulgence is unlikely to cause harm, but regular consumption should be avoided. The study's release coincides with the annual Nathan's Hot Dog Eating Contest and a weekend when Americans traditionally consume millions of hot dogs. Health officials are using the moment to encourage healthier grilling choices and raise awareness about long-term dietary risks. What People Are Saying Authors of Health effects associated with consumption of processed meat, sugar-sweetened beverages and transfatty acids: a Burden of Proof study: "We observed a statistically in type 2 diabetes risk associated with higher processed meat consumption; that is, disease risk increased with increased intake." Dr. Demewoz Haile, the study's lead author, told CNN.: "Habitual consumption of even small amounts of processed meat, sugary drinks and trans fatty acids is linked to increased risk of developing type 2 diabetes, ischemic heart disease and colorectal cancer. What Happens Next While the study is unlikely to stop Americans from enjoying hot dogs this weekend, it may influence future dietary guidelines and public health campaigns.

America Is Killing Its Chance to Find Alien Life
The Atlantic Daily, a newsletter that guides you through the biggest stories of the day, helps you discover new ideas, and recommends the best in culture. Sign up for it here. In April, scientists announced that they had used NASA's James Webb Space Telescope to find a potential signature of alien life in the glow of a distant planet. Other scientists were quick to challenge the details of the claim and offered more mundane explanations; most likely, these data do not reveal a new and distant biology. But the affair was still a watershed moment. It demonstrated that humans have finally built tools powerful enough to see across interstellar space and detect evidence of biospheres on distant worlds—in other words, tools truly capable of discovering alien life. Given the telescope technologies we astronomers have now and the ones we'll build soon, within a few decades, humans might finally gather some hard data that can answer its most profound, existential question: Is there life beyond Earth? What's arguably even more remarkable is that unless something changes very soon, the humans making that epochal discovery might not be NASA and the American space scientists who power it. The U.S. space agency is facing a funding and personnel crisis that the Planetary Society has called 'an extinction-level event.' The Trump administration's proposed 2026 budget—a version of which passed Congress and now awaits the president's signature—slashes NASA's funding by almost a quarter. That means, adjusted for inflation, NASA would get the same level of funding it had in 1961, before John F. Kennedy called for the United States to put a man on the moon. The modern version of NASA has far more on its plate: maintaining the International Space Station, hunting for Earth-killing asteroids, and using its Earth-observing satellites to help farmers monitor soil conditions. The president's budget also calls for an aggressive push to land humans on both the moon and Mars. It's hard to see how the agency can safely and accurately fulfill its current responsibilities—let alone develop advanced (and expensive) scientific equipment that would advance the search for alien life—with such reduced funding. ('President Trump's FY26 NASA Budget commits to strengthening America's leadership in space exploration while exercising fiscal responsibility,' a NASA spokesperson wrote in an email to The Atlantic. 'We remain fully committed to our long-term goals and continue to make progress toward the next frontier in space exploration, even as funding priorities are adjusted.' The White House did not respond to a request for comment.) Almost all of NASA's divisions face dramatic cuts, but the proposed nearly 50 percent slash to its Science Mission Directorate poses the greatest threat to hopes of future grand discoveries, including finding life on other worlds. SMD's engineers and scientists built the rovers that helped scientists show that Mars, now a freezing desert, was once warm and covered in rushing water. The researchers it funds developed probes that revealed vast subsurface oceans on some of Jupiter's moons. SMD is also where you'll find the folks who built the Hubble Space Telescope, the James Webb Space Telescope, and a flotilla of other instruments. These extraordinary machines have provided views of colliding galaxies 300 million light-years away, captured the death throes of stars like the Sun, and recorded portraits of interstellar clouds that birth new generations of stars and planets. In 2023, the scientists and engineers of the SMD were tasked with building the all-important Habitable Worlds Observatory, designed specifically to find alien life on planets light-years away. Slated to launch sometime in the 2040s, the HWO is planned to be about the same size as the JWST, with a similar orbit beyond the moon. Unlike the JWST, the HWO's sophisticated detectors must be able to tease out the light of an exoplanet against the billions-of-times-brighter glare of its host star, a signal as faint as the dim glow of a firefly flitting around a powerful field light at the San Francisco Giants' Oracle Park, but detected from all the way across the country in New York City. But now, many astronomers fear, NASA might never get the chance to build HWO—or carry out a slew of other missions that maintain the U.S.'s strong advantage in space science, as well as keep it ahead in the hunt for alien life. Under Donald Trump's plan, NASA would be forced to abandon 19 'active' missions. These include Juno—which is revolutionizing astronomers' understanding of Jupiter and could help them understand similarly monstrous worlds in other solar systems with other Earth-like planets—and New Horizons, a mission that took nearly 10 years to reach Pluto and is now flying into uncharted space at the edge of the solar system. The budget also decimates the future of space-science exploration. Scientists have been desperate to get back to Venus, for example, after a chemical compound associated with life was potentially detected high in its atmosphere in 2020; the two missions that would get us there are axed out of the administration's budget. The plan for the Nancy Roman Telescope, which would test key technologies necessary for the HWO, is so withered that many astronomers worry the telescope might never leave Earth. Worst, the development for the HWO takes an 80 percent cut in the president's proposed budget, going from $17 million in 2024 to just $3 million in 2026, before rebounding in 2028. The HWO represents one the most ambitious projects ever attempted, and the technological innovation needed to build it, or probes that might land on Jupiter's ocean moons, get measured across decades. In order for such missions to succeed, investments have to remain steady and focused—the opposite of what the Trump administration has proposed. Amid all the difficulties the country faces, the losses in space science might seem trivial. But American science, including space science, has paid enormous dividends in keeping the nation strong, prosperous, and worthy of the world's respect. If the original budget passes, one in every three of NASA's highly skilled workers will lose their job. The agency, in turn, will lose decades of hard-core technical experience: Not many people know how to blast a robot science rover from Earth, have it cross hundreds of millions of miles of deep space, and then land it—intact—on the surface of another planet. As the cuts take hold, plenty of NASA scientists might be forced to take jobs in other countries or early retirements they didn't want, or simply be let go. And the agency will be set back decades more into the future by choking off funding to young researchers at every level. Just as the U.S. is stumbling and falling back in its efforts to find alien life, astronomers around the world are preparing for the steep climb. The European Space Agency has a list of missions aimed at studying exoplanets. China has announced a 2028 launch date for Earth 2.0, a space telescope designed to find Earth-size exoplanets in the habitable zones of their stars. If it succeeds, that mission would put China on a path to building its own version of the Habitable Worlds Observatory. In my work as an astrophysicist, studying the possibilities of life on exoplanets, I travel around the world representing American science. In those travels, I consistently find people in other countries wearing two icons of American culture: the Yankee cap and the NASA logo. That a kid in Florence or a middle-aged guy in Bangkok would wear a NASA T-shirt is testimony to the power of its legacy. NASA—with its can-do spirit and its willingness to dream like no other organization in the history of the world—is America. If protected and nurtured, it would almost certainly lead the charge to answer that most existential question of life beyond Earth. But if this administration's shortsighted budget passes, it might be some other nation that discovers we are not alone in the universe. Article originally published at The Atlantic

'We are proud to serve our country, both on Earth and in space': NASA astronauts beam home July 4 message from ISS (video)
When you buy through links on our articles, Future and its syndication partners may earn a commission. Three NASA astronauts living aboard the International Space Station (ISS) marked Independence Day with a few heartfelt words for their compatriots here on Earth. It was written by the American members of the station's current Expedition 73 mission, Nichole Ayers, Jonny Kim and Anne McClain. All three are members of the U.S military — Ayers is a lieutenant colonel in the Air Force, McClain is an Army colonel and Kim is a lieutenant commander in the Navy, as well as a former SEAL — so Independence Day has a special meaning for them. "This is a special holiday for me. It just reminds us of the freedom that we get to enjoy and that we have enjoyed for so many years," Ayers said in a 160-second video, which was recorded on June 16 but posted by NASA on Thursday (July 3). "Protecting that freedom is important to all of us here as military officers, but also NASA astronauts," she added. "And we are proud to serve our country, both on Earth and in space." "For me, the Fourth of July represents the responsibilities that we each have — to whom much is given, much is expected," McClain said. "Our forefathers gave us the rights of life, liberty and the pursuit of happiness, and every generation must protect that for future generations." Kim said the Fourth of July is a "deep day of reflection" for him, an occasion to remember American ideals and honor the sacrifices of those who have helped uphold them. "And to those following our mission, the spirit of exploration, just like the spirit of freedom and democracy, is what has made our country so great," he added. The trio spoke in front of a large American flag, which they had affixed to an ISS module wall. They also provided more patriotic flair toward the end of the video: All three did a celebratory backflip, revealing socks with a stars-and-stripes theme.

It also houses record-setting former NASA astronaut Peggy Whitson, who's now the director of human spaceflight for the Houston-based company Axiom Space. Whitson is commanding Axiom's four-person Ax-4 mission, which arrived at the ISS on June 26 for a roughly two-week stay. Her three crewmates are pilot Shubhanshu Shukla of India; mission specialist Sławosz Uznański-Wiśniewski, a European Space Agency astronaut from Poland; and mission specialist Tibor Kapu, who hails from Hungary. There are four other people on station at the moment as well, all of them members of Expedition 73: cosmonauts Kirill Peskov, Sergey Ryzhikov and Alexey Zubritsky, as well as Takuya Onishi of JAXA (the Japan Aerospace Exploration Agency).
