Playing Hide and Seek with Planets
An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star’s motion on the sky. This new method promises to improve the efficiency of exoplanet searches, paving the way for the discovery of an Earth twin.

AI Finds that First Stars were Clustered Together
An international team has used artificial intelligence to analyze the chemical abundances of old stars and found indications that the very first stars in the Universe were born in groups rather than as isolated single stars. Now the team hopes to apply this method to new data from on-going and planned observation surveys to better understand the early days of the Universe.

Small But Mighty: New Superconducting Amplifiers Deliver High Performance at Lower Power Consumption
Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.

Spiral Pattern Gives Clue to how High-Mass Stars Form
New observations have revealed a spiral pattern in a disk of material around a still forming, but already high-mass, baby star. This indicates that there is gravitational instability in the disk, which has important implications for how high-mass stars form.

Tadpole Playing Around Black Hole
A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.

Outflows from Baby Star Affect Nearby Star Formation
New observations show an outflow of high-speed gas from one baby star colliding with a nearby dense cloud of gas where other stars are in the process of being born. These observations clearly show the outflow from a baby star affecting a neighboring star forming cloud.

Starry Tail Tells the Tale of Dwarf Galaxy Evolution
A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called “ultra-diffuse” galaxies are formed.

Model-Independent Method to Weigh Protoplanetary Disks
Astronomers have found a way to directly measure the amount of gas in protoplanetary disks without needing to make assumptions about the relative amounts of different types of gas, making this method more accurate and robust than previous methods.

Machine Learning Reveals How Black Holes Grow
Machine learning has deduced the rules governing the relationship between the growth of a galaxy and the growth of the supermassive black hole at its center. The tight correlation between the two growth rates found in this research confirms a decades-old theory.
