Using the Subaru Telescope, astronomers have identified two new dust-reddened (red) quasars at high redshifts. The finding, detailed in a paper published July 16 on the arXiv pre-print server, could improve the understanding of these rare but interesting objects.

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 for the observations to search for target candidates for New Horizons’ next observations. Astronomers from Japan are participating in the observation team together with ones from…
TRAPPIST-1 planetary orbits not misaligned
Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the evolution of planetary systems around very low-mass stars in general, and in particular the history of the TRAPPIST-1 planets including the ones near the habitable zone.

Astronomers observe high-redshift quasar PSO J006.1240+39.2219 with Subaru telescope
Using the Subaru telescope, astronomers from Taiwan have conducted spectroscopic observations of a high-redshift quasar designated PSO J006.1240+39.2219. Results of these observations, presented in a paper published March 19 on the arXiv pre-print server, provide more insights into the nature of this object.

Will we soon see potentially habitable exoplanets more clearly?
Because stars are so much brighter than their planets, we’ve barely begun to glimpse distant exoplanets, or planets orbiting distant stars. Now a new technology promises to provide better imaging of these potentially habitable exoworlds. Source: https://earthsky.org/space/exoplanets-direct-imaging-potential-habitability…
Astronomers conduct one of the most detailed studies of a stellar halo
An international team of astronomers has used the Subaru Telescope to probe the stellar halo of the nearby Messier 81 (M81) galaxy. The observations resulted in one of the most detailed studies of a stellar halo conducted to date. The study is detailed in a paper published October 31 on arXiv.org.

Worldwide observations confirm nearby ‘lensing’ exoplanet
Researchers using telescopes around the world confirmed and characterized an exoplanet orbiting a nearby star through a rare phenomenon known as gravitational microlensing. The exoplanet has a mass similar to Neptune, but it orbits a star lighter (cooler) than the Sun at an orbital radius similar to Earth’s orbital radius. Around cool stars, this orbital region is thought to be the…
The whole picture of a distant supercluster in three dimensions
Using the Subaru Telescope and Gemini-North Telescope, a team of astronomers has revealed that the supercluster CL1604, a distant supercluster located about 7.3 billion light-years away, is a large-scale 3-D structure extending over about 160 million light-years in the north-south direction. This is more than two times more extended than previously known. Until now, astronomers saw merely the “tip of the…
Saturn is our solar system’s new moon king
Astronomers have found 20 new moons orbiting Saturn, bringing the planet’s total number of moons to 82. That surpasses Jupiter, which has 79. Source: https://earthsky.org/space/saturn-20-new-moons-discovered…
Saturn Overtakes Jupiter As Host To Most Moons In Solar System
Astronomers have spotted 20 more moons orbiting Saturn, bringing the total number of Saturnian moons to 82, surpassing the 79 that are known to orbit Jupiter. The Guardian reports: The scientists discovered the moons when they set algorithms to work on decade-old images captured from the powerful Subaru telescope on Mauna Kea in Hawaii. By comparing images taken over hours and…
