One astronomer never thought of leaving Japan, but then he did and became a world best.

Osaka Metropolitan University scientists identified about 140,000 molecular clouds in the Milky Way Galaxy from large-scale data of carbon monoxide molecules, observed in detail by the Nobeyama 45-m radio telescope. Using artificial intelligence, the researchers estimated the distance of each of these molecular clouds to determine their size and mass, successfully mapping the distribution of the molecular clouds in the Galaxy in the most detailed manner to date.

Researchers used the James Webb Space Telescope to identify the precise location of a powerful energy source hidden by cosmic dust in the luminous merging galaxy IIZw096.

Supermassive black holes can launch fast-moving plasma, which emit strong radio signals known as radio jets. Despite being discovered over 40 years ago, much remains unknown about how radio jets are produced. Now, a research team, led by Tohoku University astrophysicists, has attempted to clarify how plasma gets loaded into radio jets.

Far from the white sandy beaches and palm trees of Honolulu, Hawaii, astronomers from around the world travel to the top of a volcano that looks like a plateau on Mars. Naoyuki Tamura, a project associate professor at the Kavli Institute for the Physics and Mathematics of the Universe, has been making that same journey to the top of Maunakea to supervise the construction of a new instrument for the Subaru Telescope.

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules in space at once. This is expected to enable significant progresses in the study of the evolution of the Universe and the mechanisms of star and planet formation.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using ALMA.

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation.

Researchers found that dust encircling a young gas giant can create a “safety zone,” which keeps a large moon from falling into the planet as the system evolves.

An international team of astronomers using ALMA has captured the very moment when an old star first starts to alter its environment.

Planetary scientists using ALMA revealed the secrets of the atmosphere of Titan, the largest moon of Saturn.

Astronomers at the National Astronomical Observatory of Japan have analyzed the paths of two objects heading out of the Solar System and determined that they likely originated from outside of the Solar System.

Astronomers uncovered the true identity of the fireball spotted on April 29, 2017.

Astronomers have cataloged signs of 9 heavy metals in the infrared light from supergiant and giant stars.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas.

A distant galaxy more massive than our Milky Way has revealed that the 'cores' of massive galaxies in the Universe had formed already 1.5 billion years after the Big Bang.

Researchers have discovered gigantic clouds of gaseous carbon more than a radius of 30,000 light-years around young galaxies using ALMA.

Theoreticians in two different fields defied the common knowledge that planets orbit stars like the Sun. They proposed the possibility of thousands of planets around a supermassive black hole.

Using the Cooled Mid-Infrared Camera and Spectrometer on the Subaru Telescope, astronomers have detected an unidentified infrared emission band from comet 21P/Giacobini-Zinner in addition to the thermal emissions from silicate and carbon grains.

Two peacock-shaped gaseous clouds were revealed in the Large Magellanic Cloud by observations with Atacama Large Millimeter/submillimeter Array.

Researchers using telescopes around the world confirmed and characterized an exoplanet orbiting a nearby star through gravitational microlensing.
