Astronomers have identified a possible new member of one of astronomy’s strangest classes of objects: Odd radio circles (ORCs), enormous ring-like structures visible only at radio wavelengths. The newly discovered source, J1248+4826, appears to be the most compact ORC candidate identified so far, with a ring only about 30,000 parsecs across. The paper was posted to the arXiv preprint server on May 6.
Elon Musk founded SpaceX in 2002 with the lofty goal of ferrying humans to Mars and colonizing Earth’s neighboring planet.
Elon Musk announced plans Wednesday for one of the biggest stock sales ever by taking public a space company that is currently losing billions of dollars a year.
Hundreds of companies raised a combined $70 billion by selling shares to the public in the United States last year.
Elon Musk’s SpaceX is set for the debut launch of its latest Starship iteration on Thursday, testing the most powerful version yet of the megarocket as the company targets a blockbuster initial public offering.
Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small that ordinary background noise can drown them out. Some sensors are already in daily use, while others are moving from research labs into flight tests, hospitals and field instruments.
Standardizing calculations of the helium byproducts generated in advanced fission and fusion energy system materials can increase reactor safety and longevity, according to a study led by University of Michigan Engineering with collaborators at Oak Ridge National Laboratory and its management contractor UT-Battelle.
Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the brain working together to resolve images with less energy use than anything people have invented.
A Chesapeake Bay Bridge-Tunnel Police cruiser flipped and landed on the bridge-tunnel’s guardrail in a single-vehicle wreck
Neptune’s far-flung moon Nereid may be the last of the planet’s original companions that managed to survive a cosmic crash, scientists reported Wednesday.
How come our universe is full of disorder, when all elementary particles appear to follow strictly ordered laws of physics? And are there organizing principles behind disorder and apparent chaos?
Researchers from the Institut des NanoSciences de Paris, the Kastler Brossel Laboratory and the University of Glasgow have developed an innovative method that renders a scattering medium transparent solely for information carried by entangled photon pairs, while the same medium remains completely opaque to classical light.
A team of scientists has recorded one of the most detailed views ever of a failed solar eruption, a powerful blast from the sun that never broke free. Their work is published in the journal Nature Astronomy.
LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data from NASA’s Fermi Gamma-ray Space Telescope—a breakthrough that offers new insight into the powerful magnetars believed to drive some of the universe’s brightest stellar explosions.
