‘How worlds are created’: University of Washington astronomers find evidence of planets clashing

Anastasios Tzanidakis, a UW doctoral student in astronomy, was looking through data from 2020 when he noticed an otherwise unremarkable star’s light dimming and then fluctuating wildly. What he found was evidence of planets colliding — which could shed light on how planets, like ours, form.

‘Aquila Booster’ challenges theoretical limits of particle acceleration in pulsar wind nebulae

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron and posing a challenge to the classical theory of particle acceleration in pulsar wind nebulae.

This discovery is important because the calculated particle acceleration efficiency of this celestial structure approaches or even exceeds the theoretical limits allowed under ideal magnetohydrodynamic conditions.

This study, published in Nature Astronomy, was conducted by Prof. Liu Ruoyu, Dr. Wang Kai, and doctoral student Tong Chaonan from Nanjing University, Prof. Chen Songzhan and Assoc. Prof. Wang Lingyu from the Institute of High Energy Physics of the Chinese Academy of Sciences, and their collaborators.

Newton’s 300-Year-Old Law Passes Its Biggest Cosmic Test Yet

Gravity may seem simple in everyday life. Drop an apple, and it falls. On cosmic scales, though, gravity becomes one of science’s biggest stress tests. It governs the rise of galaxies, the behavior of galaxy clusters, and the overall architecture of the universe, yet some of the universe’s motions still do not add up.

That long-running mismatch is what drove University of Pennsylvania cosmologist Patricio A. Gallardo and his collaborators to ask a basic but profound question: what if gravity itself behaves differently across the largest distances in the universe?

TESS discovers an Earth-sized planet orbiting nearby M-dwarf star

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation TOI-4616 b, is slightly larger than Earth. The finding was reported in a research paper published March 11 on the arXiv pre-print server.

Launched in 2018, TESS is in the process of scanning about 200,000 of the brightest stars near the sun, searching for potential transiting exoplanets. To date, it has identified more than 7,900 candidate exoplanets (TESS Objects of Interest, or TOI), of which 760 have been confirmed.

Nearby M dwarf draws attention of planet seekers One of the stars observed by TESS is TOI-4616—an M dwarf of spectral type M4 at a distance of some 91.8 light years away from Earth. TESS has identified a transit signal with a period of approximately 1.5 days in the light curve of this star. Now, follow-up observations of TOI-4616 conducted by a group of astronomers led by Francis Zong Lang of the University of Bern, Switzerland, have validated the planetary nature of this transit signal.

Chinese scientists discover rare-earth-rich new lunar minerals in Chang’e-5 mission samples

Chinese scientists have identified two previously unknown lunar minerals from the 1,731 grams of moon samples returned by Chang’e-5 mission, marking another major breakthrough in deep-space research. The findings were announced on Friday at the opening ceremony of the 11th China Space Day. The two newly discovered minerals have been officially approved and classified by the International Mineralogical Association. They are named magnesiochangesite-(Y) and changesite-(Ce).

Protostars ‘sneeze’ and produce rings of gas and magnetic flux as they grow

Researchers have uncovered new insights into the early development of baby stars. As published in The Astrophysical Journal Letters, a research team from Kyushu University and Kagawa University reports that during the early growth period of a baby star, the protostellar disk—the dense disk of gas and dust that surrounds the star—expels magnetic flux and forms a giant warm ring of gas about 1,000 au (astronomical units) in size. The research team explains that these “sneezes” of matter and magnetic energy help the baby star release excess energy, leading to proper star formation.

One of the many mysteries that the universe holds is how stars like our sun are born. Stars are born in areas of the cosmos called stellar nurseries, where gas and dust coalesce to form early stars called protostars. The best way to understand star formation is to observe these stellar nurseries. However, this can be difficult due to the aforementioned gas and dust obscuring the baby star.

“Thankfully, one of the most promising ways to get a clear view of protostars is to use the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile,” explains Professor Masahiro N. Machida of Kyushu University’s Faculty of Science, who led the study. “This radio telescope lets us see the different materials that make up stellar nurseries.”

Quantum chips could scale faster with new spin-qubit readout that reduces sensors and wiring

Quantum computers, devices that process information leveraging quantum mechanical effects, could tackle some tasks that are difficult or impossible to solve using classical computers. These systems represent data as qubits, units of information that can exist in multiple states at once, unlike the bits used by classical computers that represent data using binary values (“0” or “1”).

Some of the quantum computers developed in recent years store quantum information in the spin (i.e., intrinsic angular momentum) of electrons or nuclei that are trapped in small semiconductor-based structures, known as quantum dots. For these devices to operate reliably, however, engineers need to be able to precisely measure the quantum states of the spin qubits they rely on, a process that is known as qubit readout. It would also be advantageous for these states to be precisely measured in a way that is architecturally compact, or in other words, using space-efficient hardware as opposed to numerous bulkier components.

Researchers at Quantum Motion and University College London (UCL) recently introduced a new approach to clearly read out the states of spin qubits leveraging high-frequency electrical signals. This method, introduced in a paper published in Nature Electronics, was developed by Jacob F. Chittock-Wood and his colleagues while he was completing his Ph.D. at UCL.

Moon dust could stop being a nuisance and start reshaping how humans may build beyond Earth

As space agencies and private companies look toward a sustained human presence on the moon, a fundamental challenge centers on how to build strong, durable infrastructure without hauling every material from Earth. New research from Rice University points to an unexpected solution—transforming one of the moon’s most stubborn obstacles, its abrasive dust, into a valuable building resource. The study demonstrates that lunar regolith simulant, a terrestrial stand-in for the moon’s fine, abrasive dust, can be used to strengthen advanced composite materials. The work, published in Advanced Engineering Materials, was also selected for the cover of the journal’s latest issue.

The research was led by Denizhan Yavas, assistant teaching professor of mechanical engineering at Rice, in collaboration with Ashraf Bastawros of Iowa State University.

“This work started with a simple but powerful question,” Yavas said. “Lunar dust is typically viewed as a major obstacle to exploration because of how abrasive and pervasive it is. We asked whether that same material could instead be used as a resource—something that could actually improve the performance of structural materials.”
