To boldly farm fish where no one has farmed fish before. The seabass eggs, all 200 of them, were settled in their module and ready to go. The ground crew had counted the eggs carefully, checked each for an embryo, and sealed them tightly within a curved dish filled precisely to the brim with seawater. The countdown, and then—ignition! For two full minutes, the precious eggs suffered a riotous shaking as the rocket’s engines exploded to life, followed by another eight minutes of heightened juddering as they ascended to the heavens. These embryonic fish were on their way to low...

Enlarge ImageSurprise! The IBEX spacecraft, preparing to explore deep space (inset), accidentally made an important discovery about the moon.Credit: Southwest Research Institute Scientists probing the outer reaches of our solar system have hit upon an unusual phenomenon much closer to home. Instruments aboard a NASA spacecraft have detected fast-moving hydrogen atoms emanating from the moon. The atoms, which originated as protons from the sun, may help scientists study the lunar surface and other solar system objects in greater detail than believed possible. The moon is continuously being pelted by hazardous radiation. Most of it comes from the solar wind,...

Explanation: If you went outside at the same time every day and took a picture that included the Sun, how would the Sun's position change? A visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at noon near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if...

President Trump announced he was creating a new “AI Force” and designating a new AI “czar” Saturday to keep the industry from engaging in bad practices – after doubling down that fears of AI superintelligence are just another “hoax.” Trump compared a brewing panic over AI to a series of other events he has branded hoaxes. “Over the years, there have been many Hoaxes, all generated by the Radical Left Dumocrats, for purposes of destroying our Country,” he posted on Truth Social. “RUSSIA, RUSSIA, RUSSIA, UKRAINE, UKRAINE, UKRAINE, Global Warming, Impeachment Hoax #1, Impeachment Hoax #2, Men in Women’s Sports,...

[snip] Uranus has 29 confirmed moons. Only one spacecraft has ever visited the planet -- and that was in 1986 for just a few hours. Yet in the last two years alone we have discovered a brand new moon, found hidden oceans beneath multiple moons, and revealed that the dark sides of its largest moons are on completely the wrong hemisphere. In this video we break down every weird moon of Uranus -- from a world with the tallest cliff in the entire solar system, to a moon with a single mysterious bright ring sitting alone on an otherwise pitch...

The United States has publicly confirmed for the first time that it has weapons deployed in orbit. The revelation could accelerate spending on missile defense, military satellites and space security, creating opportunities for defense stocks and space ETFs while raising the risk of a costly new arms race. Air Force Secretary Troy Meink delivered the news almost casually during the Air, Space & Cyber Conference in Maryland. “We are increasing readiness against existing threats, and the United States has on-orbit space control weapons capable of defending the Joint Force against hostile adversary action,” Meink said. Then the details stopped. Meink...

Secretary of the Air Force Troy Meink made a bombshell admission this morning, disclosing that there are on-orbit weapons deployed right now to protect America’s interests in space. Those weapons support a Space Control mission set, and the U.S. Space Force has now also shared additional details about that directly with TWZ. Meink first made mention of what he described as “on-orbit space control weapons” during his keynote speech earlier today at the Air & Space Forces Association’s (AFA) 2026 Air, Space & Cyber Conference, at which TWZ is in attendance. As head of the Department of the Air Force,...

Since I am, by nature, a compassionate individual, I had been thinking of how we might Sokal the Proceedings of the National Academy of Science (PNAS). It is for their own good. Alan Sokal: remember him? He’s the physicist who submitted the scam article “Transgressing the Boundaries: Toward a Transformative Hermeneutics of Quantum Gravity” to the oh-so-prestigious postmodern journal Social Text. Postmodernists are intellectuals who are so jealous of the success of real scientists, that they pretend that scientists’ accomplishments are nothing special. They are the sort of people who authoritatively state, “There is no truth,” or “‘Truth’ is a...

Explanation: Nā ʻUhane Māhoe Huki Pū i ke Ola, is the Hawaiian name given to this image of a pair of spiral galaxies locked in a mutual gravitational embrace. Some 200 million light-years distant toward the high flying constellation Pegasus their spectacular, galactic scale merger is captured in sharp detail in the image from the 8.1 meter Gemini North telescope on Maunakea, Hawai‘i. The galaxy pair, known as NGC 7253 and Arp 278, was chosen as a target, researched, and given a Hawaiian name by high school students in the joint Gemini Observatory and University of Hawaiʻi Project Hōkūlani internship...

The Hollow Earth Perhaps some of the most bizarre scientific theories ever considered were those concerning the possibility that the Earth was hollow. One of the earliest of these was proposed in 1692 by Edmund Halley. Edmund Halley was a brilliant English astronomer whose mathematical calculations pinpointed the return of the comet that bears his name. Halley was fascinated by the earth's magnetic field. He noticed the direction of the field varied slightly over time and the only way he could account for this was there existed not one, but several, magnetic fields. Halley came to believe that the Earth...

SpaceX is targeting Sunday, August 30 for Falcon Heavy’s launch of NASA’s Roman Space Telescope mission from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Liftoff is targeted for 7:26 a.m. ET, with a backup opportunity available on Monday, August 31 at 7:22 a.m. ET. A live webcast of this mission will begin about one hour prior to liftoff, which you can watch here and on X @SpaceX. This is the first and third flight for the two first stage side boosters supporting this mission, which previously launched the GOES-U and Viasat-3 F3 missions. Following stage separation,...

In August of 2006, astronomers at the International Astronomical Union (IAU) democratically voted to reclassify Pluto as a dwarf planet — but 20 years later, with our greater knowledge and understanding of planetary systems, is it time to revisit the controversial decision? Should Pluto be called a planet again? For several years before the IAU vote, there had been agitators among the astronomical community lobbying for our solar system's nine worlds to become eight, and for Pluto's planetary status to be revoked. In 2000, Neil DeGrasse Tyson even went as far as to remove Pluto from the planets display at...

Anew report published by U.S. Sen. Rand Paul, R-KY, highlights more than $1 trillion worth of taxpayer money spent on projects that he argues wastes and abuses taxpayer money. Tucked in the report are three programs funded by federal agencies using millions of taxpayer dollars to experiment on cats. The details are explicit and gruesome.

At Kimmeridge Bay [Dorset, UK] on the Jurassic Coast, the rocks have a bit of a pattern to them. And there's a good reason for that! It's a record of changes in Earth’s climate that were driven by something happening far beyond Dorset: the changing geometry of Earth’s orbit around the Sun... Because Earth's orbit changes over time in cycles! Welcome to Milancovich cycles! This is far from the only rock unit that shows this, and in fact the Blue Lias around Lyme Regis is also pretty famous for this, but I found this cool paper that really investigated it...

A clever swap has extended the historic Voyager 2’s mission in interstellar space. Engineers are hoping to do the same for Voyager 1. An ambitious effort to boost an aging probe on its journey through the uncharted territory of interstellar space seems to have found success. Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have spent the last few months implementing what they nicknamed the “Big Bang” fix to buy the historic Voyager 2 spacecraft more time to continue its science mission. Voyager 2 is roughly 21.35 billion kilometers (13 billion miles) away from Earth, while its twin, Voyager...

This artist’s concept shows the red supergiant star Betelgeuse and a companion star orbiting within the supergiant’s tenuous outer atmosphere. Artwork: NASA, ESA, Elizabeth Wheatley (STScI); Science: Andrea Dupree (CfA) Betelgeuse has always been something of a mystery. And by “mystery,” I mean a source of endless fun, fascination and frustration for astronomers. Betelgeuse is one of the brightest stars in the sky, marking the right shoulder of the constellation Orion. It’s a red supergiant, a massive star with more than a dozen times the sun’s heft, that’s blasting out many tens of thousands as much light as our own...

At the quantum scale, tiny particles behave in bizarre ways. One reason for this is the uncertainty principle, which says that the more you know about where a quantum particle is, the less you can know about how fast it’s moving, and vice versa. The new uncertainty principle relates to fractals, shapes that remain equally complex no matter how much you zoom in on them. Around a decade ago, Semyon Dyatlov was studying whether quantum particles behave differently than ordinary particles when put into the same chaotic situations. Sometimes, an object moving chaotically can become trapped into following a fractal-like...

Researchers are shell-shocked at the latest marine discovery. Dolphins have been filmed using shells to ensnare their prey off the coast of Australia, marking the first time this clever tactic has been caught on camera, per a bombshell paper in Marine Mammal Science. “The second I saw that shell in the air, I immediately knew what was happening,” the study’s head author, Alexis Levengood, a marine mammal biologist at the University of the Sunshine Coast in Queensland, told ScienceAlert. Levengood said she and her team were on a research vessel off Hervey Bay when they spotted a female Pacific bottlenose...

Popocatepetl volcano is just east of Mexico city and is the 5th highest peak in North America ( 17,694 feet (5,393 meters) tall.) It is erupting steam right now. You can slide the time backward to see the last 12 hours. This mountain is where I did my first technical climb following the "Ventorillo Route" up the inactive vent on the right hand skyline, across the saddle and up the glacier to the summit.

Jacob Tsimerman won the biggest prize in math. Now he’s working on the most important problem of his career.When he won the Fields Medal last week, Jacob Tsimerman accepted the most prestigious honor in math wearing a powder-blue tuxedo with satin lapels.Then he made an announcement as striking as his tux. After the ceremony, the four winning mathematicians were asked what they planned to do next. One said he would keep working on partial differential equations, one said he wanted to experiment with artificial intelligence and one said she had absolutely no idea. That left Tsimerman.“I’ll be starting a position...
