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.

Searching for tiny, ancient black holes proposed by Stephen Hawking to see if they might be dark matter.

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.

Chair Professor Il Soon Hwang, who joined the School of Mechanical Aerospace and Nuclear Engineering at South Korea's Ulsan National Institute of Science and Technology (UNIST), has been selected to lead the 'Nuclear Convergence Technology Development' project by the Ministry of Science and ICT (MSIT) and National Research Foundation (NRF).

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled the dynamics of the bloch point in an asymmetric permalloy disk.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has shed new light on the mysterious origin of such ultra-high-energy cosmic rays (UHECRs) that has puzzled astrophysicists for decades.

An international team of researchers has discovered a novel method that might verify the existence of a new hypothetical type of particle, namely ultralight bosons, by using observation of the gravitational waves emitted by a smaller black hole orbiting a larger black hole.

Japanese researchers contribute to paradigm-shifting observations of the gargantuan black hole at the heart of distant galaxy Messier 87.

An international team has found evidence dark matter may not be made of tiny black holes.

Astronomers have found a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system. This observations show that binary stars form together.

Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can’t explain this much dust in a galaxy this young, forcing us to rethink the history of star formation.

Researchers spotted the formation sites of planets around a young star resembling our Sun. Two rings of dust around the star, at distances comparable to the asteroid belt and the orbit of Neptune in our Solar System, suggest that we are witnessing the formation of a planetary system similar to ours.

A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the early Universe. This increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common SMBHs were early in the Universe's history.

A team of experts in nuclear fusion and astronomy has computed high-accuracy atomic data for analyzing light from a kilonova, a birth place of heavy elements. They found that their new data set could predict kilonovae brightness with much better accuracy than before. This aids our understanding of the cosmic origins of heavy elements.

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 quiet black holes expected to be lurking in our Galaxy. These results provide a new method to search for other hidden black holes and help us understand the growth and evolution of black holes.

New study finds dark matter may scatter against each other only when they hit the right energy, which could explain why galaxies from the smallest to the biggest have the shapes they do.

Images of more than ten million galaxies are helping physicists map dark matter, revealing clues about how the universe behaves.

Astronomers using ALMA have detected various complex organic molecules around the young star V883 Ori. A sudden outburst from this star is releasing molecules from the icy compounds in the planet forming disk.

“It’s not that Newton’s theory was wrong,” says Professor Barry Barish, an experimental physicist from the California Institute of Technology and University of California, Riverside. “It was just incomplete and didn’t describe all of nature,” he says.

For the first time ever, astronomers have detected a 1.3 km radius body at the edge of the Solar System. Kilometer sized bodies like the one discovered have been predicted to exist for more than 70 years. These objects acted as an important step in the planet formation process between small initial amalgamations of dust and ice and the planets.
