A team of astronomers has used archived ALMA observations to identify for the first time the characteristic radio recombination lines associated with shells of ionized gas surrounding Solar System-sized proplyd disks in the Orion Nebula Cluster, at a distance of 1000 light-years from Earth.

Astronomers Discover ‘Space Tornadoes’ Around the Milky Way’s Core
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have sharpened our view of the turbulent region surrounding the supermassive black hole at the core of our galaxy by a factor of 100, discovering a surprising new filamentary structure in this mysterious region of space.
NRAO and SpaceX Coordinate to Protect Radio Astronomy
NRAO and SpaceX have engaged in coordinated experiments involving NRAO telescopes and the Starlink satellite constellation for over two years. Early experiments began in late 2021 with the deployment of working Starlink user terminals near the Jansky Very Large Array (VLA) in New Mexico and have continued to the present day. These experiments highlight the ways in which satellite constellations and radio telescopes might be able to coexist, provided there is mutual awareness of what the other is doing.
Supported by the National Science Foundation, NRAO and SpaceX are developing a system called Operational Data Sharing (ODS) that provides the current status (position in the sky and observing frequency) of two of its telescopes: the VLA in New Mexico and the Green Bank Telescope (GBT) in West Virginia. SpaceX is able to incorporate these data into its operational algorithm so that its Starlink satellites can steer their downlink beams away the NRAO telescope “boresight” (where the telescopes are pointed in the sky) at the moment an observation is taking place. This adaptation helps to ensure critical internet connectivity for users of the Starlink system while protecting and potentially expanding the frequency bands that radio astronomers can use for their research.
For more details on this developing system, see a recent video produced for NRAO by One World Media above.
