Astronomers using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments are unveiling new scientific research that probes some of the most extreme environments in the universe. This news will be shared in press conferences at the 248th American Astronomical Society (AAS) meeting in Pasadena, June 14th-18th.

Milky Way’s Black Hole Finally Caught ‘Breathing’
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have finally found clear evidence that the supermassive black hole at the center of the Milky Way, Sagittarius A*(Sgr A*), is blowing a hot cosmic wind – something scientists have been hunting for over 50 years.

Bavarian state government and regional universities fund construction of antenna on Germany’s highest peak
The U.S. National Science Foundation National Radio Astronomy Observatory has announced a significant collaboration with the Bavarian State Government to construct a cutting-edge radio telescope atop Germany’s highest mountain. This radio telescope will use the design of the proposed NSF NRAO’s Next Generation Very Large Array (ngVLA).
Known as the Wetterstein Millimeter Telescope (WMT), this antenna could interface with the NSF NRAO’s proposed ngVLA, while also having the capability to function independently. The WMT will be strategically positioned at the summit of the Zugspitze, offering exceptional observing conditions due to its high altitude and clear skies. This location can significantly improve the antenna’s sensitivity and resolution across the millimeter wavelength range, allowing for groundbreaking astronomical observations.
The project is funded by the Bavarian State Government, as announced in their recent press release. “The Wetterstein Millimeter Telescope will be an exciting research facility and further opens up the possibility of one day establishing a global ngVLA network,” said ngVLA Project Scientist Eric Murphy of the NSF NRAO. “Its placement on the Zugspitze provides unparalleled observing conditions, which can enhance the overall sensitivity and resolution of the ngVLA. This may enable astronomers to conduct unprecedented research across a wide range of astrophysical topics.”
The WMT is not only a significant scientific achievement in its own right, but also has the potential to act as a catalyst for the development of a larger, dedicated interferometric array. Such an array, which could potentially include up to 16 antennas, would leverage the considerable astronomical expertise and infrastructure already present in Germany, and could expand the NSF NRAO’s proposed ngVLA reach and scientific impact.
