Interplay Between Magnetic Force and Gravity in Massive Star Formation
The magnetic field is part of one of the four fundamental forces in nature. It plays a vital role in everyday life, from producing electricity…
Untangling the Formation of Planetary Systems With Heavy Hydrogen
An international research team using the Atacama Large Millimeter/submillimeter Array (ALMA) revealed the distribution of heavy hydrogen, or deuterium, in planet formation sites with the…
Studying the Sun From Far Away Like a Star to Understand Stellar Flares and Exoplanets
New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to…
Earth 16,000 MPH Faster, 2000 Light-Years Closer to Supermassive Black Hole in the Center of the Milky Way
Earth just got 7 km/s (~16,000 mph) faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way…
Artificial Intelligence Identifies 80,000 Spiral Galaxies – Promises More Astronomical Discoveries in the Future
Astronomers have applied artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have achieved a very high…
Astronomers Detect Hidden Black Hole Lurking at Galactic Center
Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud. This intermediate-mass black hole is one of over 100 million…
New Study Completely Changes Our Understanding of Stellar Evolution
At the end of its life, a red supergiant star explodes in a hydrogen-rich supernova. By comparing observation results to simulation models, an international research…
Astronomers Raise Doubts About the Relation Between Protoclusters and Quasars
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 “protoclusters,” the progenitors of galaxy clusters, in the early Universe, about…
Astronomers Use New Data to Create Extraordinary Dark Matter Map
A research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter…
HINODE Satellite Views Record Breaking Solar Magnetic Field
Magnetism plays a critical role in various solar phenomena such as flares, mass ejections, flux ropes, and coronal heating. Sunspots are areas of concentrated magnetic…
Subaru Telescope Helps Create the Most-Extensive Map of Neutral Hydrogen Gas in the Early Universe
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…
Astronomers Detect Signs of an Invisible Black Hole at the Center of the Milky Way
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…
Titania May Provide False Signs of Life on Habitable Exoplanets
New research from the National Institutes of Natural Sciences shows that a previously unconsidered photochemical mechanism by titanium (IV) oxide (titania) can produce abiotic oxygen…
Astronomers Observe a Long-Hypothesized Mechanism for Coronal Heating
A team of astronomers has observed a long-hypothesized mechanism for coronal heating in which magnetic waves are converted into heat energy. Modern telescopes and satellites…
Astronomers Uncover the Ghostly Remnants of Galaxy Interactions
Using the Subaru Telescope, a team of astronomers reveal the ghostly remnants of galaxy interactions in a nearby galaxy group. Astronomers using the Subaru Telescope’s…
Astronomers Reveal Nine Large Concentrations of Dark Matter
Using weak gravitational lensing the newly developed Hyper Suprime-Cam on the Subaru telescope has revealed nine large concentrations of dark matter, each the mass of…
Nova Delphini 2013 Produces a Large Amount of Lithium
Using the 8.2-meter Subaru Telescope High Dispersion Spectrograph (HDS), a team of astronomers observed Nova Delphini 2013 and discovered that the outburst is producing a…
