Image: Hubble captures star-studded cluster

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way’s most massive globular clusters, or spherical collections of gravitationally bound stars.

Astronomers build a one-stop universe data hub

Astronomers spend much of their time mapping the universe, but until now their results have been collected and archived in so many different ways that the data can’t talk to each other.

Unraveling a long-standing solar mystery: The extreme thinness of the sun’s tachocline layer

Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun’s tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions of high-energy particles and radiation from the sun known as “space weather.”

Hidden jet from a ‘missing-link’ black hole lights up the radio sky

Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermediate-mass black hole tears apart a star, revealing what appears to be the off-axis afterglow of a powerful jet. The research is published in The Astrophysical Journal […]

Wavelength-multiplexed diffractive optical storage enables massively parallel image retrieval

The explosive growth of data generated by artificial intelligence, cloud computing and modern digital infrastructure is placing increasing pressure on existing information storage technologies. Although magnetic storage systems such as hard disk drives remain the dominant platform for digital storage, they face challenges including rising costs, limited lifespan and relatively slow information retrieval.

Space sensor could spot hidden nuclear weapons in orbit with 99% accuracy

In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit in 2022, just a few weeks before the country’s full-scale invasion of Ukraine.

Long-theorized electron-on-helium qubit achieves strong coupling to a single microwave photon

Quantum computers, devices that store and process information leveraging the principles of quantum mechanics, have been found to be promising for tackling some problems that cannot be solved by classical computers. Quantum computers store data in the form of qubits (i.e., quantum bits), units of information that can exist in combinations of different states, instead […]

Waymo calls cops on passengers, delivers them to Calif. police

Black hole collisions may follow entropy law, offering simpler remnant predictions

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—that are strong enough to be detected with precision instruments on […]

Another success for Hayabusa 2 as it completes a flyby of asteroid Torifune

Hayabusa 2’s primary mission is now well in the past. JAXA’s asteroid-sampling spacecraft rendezvoused with asteroid Ryugu in June 2018. It studied the asteroid for 1.5 years and gathered a sample that was returned to Earth in December 2020.

JWST’s ‘overmassive’ early black holes may not be so massive after all

Astronomers studying a population of unusually X-ray-silent and overmassive black holes discovered by the James Webb Space Telescope have found that they may not be as massive as they appear. The new paper, outlining a plausible scenario that would produce such black holes, was published in Astronomy & Astrophysics on June 19.
