Puzzling image from the James Webb Space Telescope explained in two new studies

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.

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.
