When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. By the time they pass through Earth, such cosmic ripples are barely discernible.
On April 8, 2024, people across the world witnessed a solar eclipse, a relatively rare event in which the moon occults (blocks out) light from the sun. To capture this event, volunteers at 143 observatories across the U.S. trained their equipment on it as part of NASA’s Eclipse Megamovie citizen science project. The images they took were groundbreaking and provided some of the most detailed images to date of the sun’s corona. After nearly two years of production and editing, the Eclipse Megamovie team has released the dataset from this project.
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures linked to chiral phonons in a ferrimagnetic material, revealing a previously elusive relationship between lattice vibrations and magnetic excitations. Reported in Physical Review Letters, the results could help researchers better understand how heat, sound and spin interact in quantum materials.
As the U.S. plans to return to the moon with the upcoming Artemis II mission, a question endures: What will future lunar explorers eat? According to new research from The University of Texas at Austin, the answer might be chickpeas.
Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing estimates of the universe’s age rather than its expansion rate. Using precise stellar data, they determined ages for carefully selected very old Milky Way stars and found a most likely age of about 13.6 billion years.
Healable spacecraft structures could soon be possible thanks to cutting-edge composite technology. Swiss companies CompPair and CSEM with Belgian company Com&Sens have partnered with the European Space Agency (ESA) to modify their self-healing carbon fiber product for use in space transportation.
When most people think of a supernova, they’re thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They’ve used up their supply of hydrogen and continue fusing heavier elements until the star can’t support its own mass. The core collapses and they explode, outshining their entire host galaxy for months.
What happens when a solar superstorm hits Mars? Thanks to the European Space Agency’s Mars orbiters, we now know: glitching spacecraft and a supercharged upper atmosphere.
A Japanese startup’s third attempt to put a satellite in orbit failed on Thursday after its rocket spiraled back to Earth shortly after takeoff.
Electrons can be “kicked across” solar materials at almost the fastest speed nature allows, scientists have discovered, challenging long-held theories about how solar energy systems work. The finding could help researchers design more efficient ways of harvesting sunlight and converting it into electricity. The research is published in Nature Communications.
For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar wind nebula (PWN). This observation extends to the highest energies, above 100 tera-electron volts (TeV), providing new insights into the behavior of cosmic rays and magnetic fields within the Milky Way.
NASA announced it had found the source of a helium flow blockage that forced it to roll the Artemis II rocket back from the launch pad at Kennedy Space Center and delay its lunar fly-by mission until at least April.
Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic spectrum, the ultrathin device requires no external power, operates at room temperature and can be readily integrated into on-chip applications.
Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum computers can solve complex equations at staggeringly fast speeds that vastly outpace regular computers. In real hardware, the operations of quantum computers often deviate from the ideal behavior because of device imperfections and unwanted noise from the environment. To build reliable quantum machines, researchers need a way to accurately determine what a quantum device is actually doing.
Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits visible during logical calculation and evaluates them. The new method was demonstrated on an ion trap quantum processor in Innsbruck. It can be used to identify critical error sources—a key to developing more robust, fault-tolerant quantum processors.
