Subaru Telescope and New Horizons explore the outer solar system

Collaborative observations with NASA's New Horizons mission have been ongoing at the Subaru Telescope since May 2020. Hyper Suprime-Cam (HSC), the wide field camera mounted on the prime focus of the Subaru Telescope, is used ...

New method to study barred spiral galaxies

Analysis of gas motion in 20 nearby spiral galaxies has revealed a clear difference between those with bars and those without bars. This suggests that already available data on gas motion can be used to study bars in spiral ...

International team observes innermost structure of quasar jet

An international team of scientists has observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of ...

Subaru telescope captures comet Lovejoy's tail

A team of astronomers from Stony Brook University (the State University of New York at Stony Brook), the National Astronomical Observatory of Japan (NAOJ), and others used Suprime-Cam, Subaru Telescope's wide-field, prime-focus ...

ALMA demonstrates highest resolution yet

ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like structure of gas and that ...

Deep neural network to find hidden turbulent motion on the sun

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the sun. Tests on three different sets of simulation data showed that it is possible to infer ...
