An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match…
Astronomers found a number of stellar eggs containing baby stars around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous…
Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster,…
At around 1 a.m. local standard time on April 29, 2017, a fireball flew over Kyoto, Japan. Compared to other fireballs spotted from Earth, it…
Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined…
The first dataset from the Hyper Suprime-Cam Subaru Strategic Plan (HSC-SSP) can be seen easily with the “HSC Viewer” on your PC or tablet. The…
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets…
Using the Subaru Telescope, astronomers create the most-extensive map of neutral hydrogen gas in the early universe. Scientists have used the Suprime-Cam on the Subaru…
Using the Nobeyama Radio Telescope, a team of astronomers has detected signs of an invisible black hole with a mass of 100 thousand times the…
Astronomers used the Subaru Telescope to study active supermassive black holes in merging galaxies, revealing that local physical conditions near SMBHs rather than general properties…
An international team of astronomers has observed an infrared dark cloud surrounding a baby star that is about ten times larger than those found around…
New Subaru Telescope observations of super-Earth GJ 1214 b show that the exoplanet is likely to have a water-rich atmosphere. A Japanese research team of…
Astronomers used the Subaru Telescope to observe a disk around the young star RY Tau, finding that a “fluffy” layer above the disk appears to…
Using the 45m Telescope at Nobeyama Radio Observatory and the 10m ASTE telescope, scientists were able to make high-sensitivity video imaging observations of the full…
Using two telescopes at Okayama Astrophysical Observatory, scientists have observed the atmosphere of super-Earth exoplanet GJ3470b for the time, measuring the planetary mass, radius, and…
Astronomers continue to research the HAT-P-7 planetary system, looking for new insights into how retrograde planets may form and endure. Astronomers have used the Subaru…
By masking the bright light from a central star, HiCIAO can detect the detailed features of a star’s disk and the objects that it contains,…
Using data from the Subaru Telescope and optical spectroscopy from the W. M. Keck Observatory, astronomers concluded that the ultraluminous infrared galaxy Arp 220 developed…
