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.

A New Type of Supernova Illuminates an Old One
A worldwide team of astronomers has discovered evidence for a new type of stellar explosion -- an electron-capture supernova. While this type has been theorized for over 40 years, this is the first observed example. These findings provide clues to the precursor of the Crab Nebula, a supernova observed by cultures all over the world in 1054.

ALMA Discovers Earliest Gigantic Black Hole Storm
Researchers using the ALMA discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe.
