University of Missouri researchers have uncovered evidence that challenges one of astronomy’s most trusted assumptions, a breakthrough that could reshape how scientists measure galaxies and reconstruct the history of the universe.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is a partner, have captured the first direct, high-resolution images of a magnetic field wrapped tightly around the outflow of gas streaming away from a forming star—evidence that solves a decades-old puzzle about how young stars sculpt the powerful jets that form them.
When certain atoms are irradiated with laser light, they can produce a very different kind of laser light: laser pulses with extremely high frequencies in the X-ray range. These laser pulses, which helped achieve record-breaking results at TU Wien in the 1990s, were the subject of the 2023 Nobel Prize in Physics.
The scramble for protective glasses has reached fever pitch across Europe ahead of Wednesday’s rare total solar eclipse, as pharmacies, opticians and other shops struggled to keep them in stock.
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky Way galaxy. The observations reveal that the evolved star IRS 3 continues to enrich its surroundings with newly formed material despite the intense radiation environment around Sagittarius A*.
A Dallas Police officer fired four shots at an undercover officer who was approaching a vehicle theft suspect with their gun drawn
Despite the deputy’s efforts to put out a vehicle fire, the suspect fleeing the stop was killed in the crash
I’ll admit to using AI for things it was probably never designed for. When my van threw a fault I couldn’t immediately figure out—one that seems notorious for trips back and forth to a repair shop—I ended up in a long (but cheaper) back-and-forth with an AI system, working through the symptoms. The same happened with a run of gutters and with stud framing in my house. It isn’t magic, and perhaps more often than I’d like, it’s wrong, but as a way of thinking through a problem with something that’s read more manuals than I ever will, it has earned its place in the toolbox. So I read this next story with some sympathy and interest.
A grand jury charged Dequwan Houchins, 30, with five counts of misconduct in office and four counts of falsifying public records
Most current space activities operate close to Earth in what is called near–Earth orbit. However, as more satellites and other infrastructure begin to extend beyond that region, maintaining situational awareness of those objects will be crucial.
Researchers at the University of Basel and the Technical University of Munich have developed a new method to reveal the collective motion of electrons in one of the most elusive states of matter: the Wigner crystal. Using light, the physicists were able to uncover previously inaccessible properties of this fragile quantum state.
The suspect broke away from Sacramento County deputies and grabbed a gun resting on his right hip, prompting deputies to fire shots
In the early hours of Wednesday morning, Aug. 5, the upper stage of a Falcon 9 rocket crashed into the moon in an uncontrolled collision.
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked away underground or lost to space.
Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is actually produced locally, component by component, deep inside the circuitry.
