Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical counterpart, the nonlinear version can arise even without breaking time-reversal symmetry, and its magnitude is tied to deep geometric properties of electron wave functions. So far, however, the behavior of the effect when a magnetic field is applied has remained poorly understood.

One well-done gas giant, coming right up! That’s the latest from researchers analyzing NASA’s James Webb Space Telescope observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its sun-like star. The research team is presenting its study and preliminary findings Tuesday at the 248th meeting of the American Astronomical Society (AAS248) in Pasadena, California.

A team of scientists has used NASA’s Goldstone Solar System Radar and the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to carry out the most extensive radar study to date of Europa, the ocean world orbiting Jupiter. By repeatedly “pinging” Europa with 3.5-centimeter (1.4-inch) radio waves between 2011 and 2024, the team measured how the moon reflects radar signals and confirmed that its icy surface scatters radio energy in an unusually strong and complex way not seen on rocky worlds.

New research led by a scientist at IPAC—a science and data center for astrophysics and planetary science at Caltech—studying the hot Jupiter CoRoT-2 b has settled on one of the three leading hypotheses explaining why its atmosphere has a hot spot in the opposite direction from that seen on all other exoplanets of this type.

Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter. They are also the most abundant particles with mass in the universe and can be created through a variety of processes, such as the decay of heavy particles, nuclear reactions in the sun and the explosions of stars.

SpaceX shares surged again Tuesday, lifting Elon Musk’s rocket company into the world’s top five in market value for most of the session as a record-breaking IPO gave way to a torrid buying frenzy.

Even at this early stage in our spacefaring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers—Pioneer 10 and 11, Voyager 1 and 2, and New Horizons—are all on escape trajectories out of the solar system and might someday enter another one. They will no longer be operational at that point, but they serve as proof of concept that spacefaring civilizations do indeed build interstellar probes.

NASA’s “rapid-response” space telescope is slowly falling out of orbit, but a daring mission this summer could allow the Neil Gehrels Swift Observatory to continue scanning the sky for many more years to come. In the first mission of its kind, a spacecraft will launch from Earth and rendezvous with Swift to boost it to a higher altitude and extend its life.

Researchers using two of humanity’s most powerful observatories—NASA’s James Webb and Hubble Space Telescopes—have definitively shown that Terzan 5 is not a globular star cluster, as it was once classified, offering new insight into how galaxies like our own form and evolve over time.

Astronauts aboard the International Space Station have switched on NASA’s newly upgraded Cold Atom Lab, a one-of-a-kind facility designed to improve how scientists explore the fundamental workings of matter and develop new quantum technologies. By leveraging the unique environment of microgravity in space, the lab can accomplish cutting-edge science impossible to do anywhere else.

Cleveland Clinic researchers are unlocking quantum computing’s full potential through the creation of a new computing paradigm inspired by the human brain. Fabio Cumbo, Ph.D., research associate in the lab of Daniel Blankenberg, Ph.D., associate staff, Computational Life Sciences, is developing the model, called quantum hyperdimensional computing (QHDC).

Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can “remember” past mechanical experiences; that is, the way they respond to a force can depend on how they have responded to external forces before.

Have you ever been out at night and seen a streak of light blast across the sky and disappear? Ever wonder where that shooting star came from, or how it got to be in your sky?

A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third galaxy that has no dark matter.
