Rewriting the Past and Future of the Universe
New research has improved the accuracy of the parameters governing the expansion of the Universe. More accurate parameters will help astronomers determine how the Universe grew to its current state, and how it will evolve in the future.

Accurate Measurement of Permittivity Advances Radio Telescope Receivers and Next Generation Telecommunication Networks
Researchers invented a novel method to measure the permittivity of insulators 100 times more accurately than before. This technology is expected to contribute to the efficient development of sensitive radio receivers for radio telescopes as well as to the development of devices for the next generation communication networks, “Beyond 5G/6G.”

VERA Unveils Surroundings of Rapidly Growing Black Holes
An international team of astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes operated by NAOJ, to uncover valuable clues about how rapidly growing “young” supermassive black holes form, grow, and possibly evolve into more powerful quasars.

Stellar Cradles and Graves Seen in Farthest Galaxy Ever
New observations using the ALMA have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years away. This is the farthest that such structures have been observed.

ALMA Digs Deeper into the Mystery of Planet Formation
An international research team used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe disks around 19 protostars with a very high resolution to search for the earliest signs of planet formation. This survey was motivated by the recent findings that planet formation may be well-underway in the more-evolved proto-planetary disks, but until now there had been no systematic study to search for signs of planet formation in younger protostellar systems.

Molecular Filament Shielded Young Solar System from Supernova
A team led by Doris Arzoumanian at the National Astronomical Observatory of Japan proposed a new explanation of how the Solar System acquired the amount of isotopes measured in meteorites while surviving the supernova shock.

Observations of High-Mass Star Seeds Defy Models
Astronomers have mapped 39 interstellar clouds where high-mass stars are expected to form. This large data set shows that the accepted model of low-mass star formation needs to be expanded to explain the formation of high-mass stars. This suggests the formation of high-mass stars is fundamentally different from the formation of low-mass stars, not just a matter of scale.

Unburying CIZA Galaxy Cluster
Now astronomers have used a newly upgraded world-leading radio telescope to unbury the radio emissions from a galaxy cluster known as CIZA1359. The signal has until now been buried in noise from a nearby foreground object.
