Unprecedented Discovery: Planet-Forming Disk Found Beyond Our Galaxy

Astronomers have discovered the first extragalactic accretion disk, a swirling disk of material feeding a young star, located in the Large Magellanic Cloud, a neighboring galaxy to the Milky Way. The disk is similar to those found in the Milky Way and provides direct evidence that stars and planets form in other galaxies. The discovery was made using the Atacama Large Millimeter/submillimeter Array (ALMA), and the researchers believe that this finding could help shed light on the early stages of planet formation.

Supermassive Black Holes Shape Galaxy Chemistry

New research using the Atacama Large Millimeter/submillimeter Array (ALMA) provides strong evidence that supermassive black holes (SMBHs) alter the chemistry of their host galaxies. The study focused on the barred spiral galaxy NGC 1068 and mapped the distribution of 23 different molecules using ALMA. The researchers found different chemical distributions in the circumnuclear disk (CND) and the starburst ring (SBR) of NGC 1068, indicating the influence of SMBHs on the presence and abundance of chemicals. The study also detected unexpected concentrations of hydrogen cyanide (HCN) in the CND, possibly due to strong shocks, and observed the first detection of silicon monoxide (SiO) in NGC 1068. These findings shed light on the complex interactions between SMBHs and their host galaxies.

Ancient Magnetic Galaxy Sheds Light on Milky Way's History

Astronomers have detected a magnetic field spanning 16,000 light years in an ancient galaxy, known as 9io9, which existed over 11 billion years ago. This is the earliest detection of galactic magnetism in the universe. The discovery was made using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. The weak magnetic field suggests that intense star formation in the early stages of the galaxy's life helped propagate the magnetic field across the galaxy. This finding provides new insights into the formation of galactic magnetic fields and their role in galactic evolution.
