First ALMA Animation of Circling Twin Young Stars

Researchers analyzed the accumulated data from ALMA and depicted the motion of a young twin star system XZ Tauri over three years. This first-ever “ALMA Animation” of twin stars sheds new light on the origins of the binary stars and the planets to be formed around them.

Unveiling Galaxies at Cosmic Dawn That Were Hiding Behind the Dust

While investigating the data of young, distant galaxies observed with the Atacama Large Millimeter/submillimeter Array, unexpected emissions coming from seemingly empty regions in space were detected. A global research team confirmed that they came actually from two hitherto undiscovered galaxies heavily obscured by cosmic dust.

Untangling the Formation of Planetary Systems with Deuterium

An international research team using ALMA revealed the distribution of heavy hydrogen, or deuterium, in planet formation sites with the highest resolution ever achieved. This provides clues to understand the physical and chemical conditions during the formation of exoplanets and Solar System objects.

Small Amount of Lithium Production in Classical Nova

A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova explosions alone cannot explain the amount of lithium seen in the current Universe. This is an important result for understanding both the explosion mechanism of classical novae and the overall chemical evolution of the Universe.

Observation, Simulation, and AI Join Forces to Reveal a Clear Universe

Japanese astronomers have developed a new artificial intelligence (AI) technique to remove noise in astronomical data due to random variations in galaxy shapes. This is a powerful new tool for analyzing big data from current and planned astronomy surveys.
