Astronomers Discover Massive Molecular Cloud Hidden in Milky Way
In a new study published in the Astrophysical Journal, researchers using the U.S. National Science Foundation Green Bank Telescope (NSF GBT) have peered into a molecular cloud known as M4.7-0.8, nicknamed the Midpoint cloud. Their observations have revealed a dynamic region bustling with activity, including potential sites of new star formation.

A landmark event for astronomy took place on April 25, 2025, as mtex antenna technology GmbH officially handed over the prototype antenna for the proposed Next Generation Very Large Array (ngVLA) to the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) at a ceremony held at the NSF Very Large Array site on the Plains of San Agustin, New Mexico. View our released image gallery.
The handover ceremony brought together a diverse group of attendees, including colleagues from Mexico and Germany, New Mexico state representatives, contractors from mtex, NRAO and ngVLA project staff, and members of the ngVLA Science and Technical Council, . Notable speakers included NRAO Director Tony Beasley and mtex CEO Lutz Stenvers, who highlighted the partnership and the scientific vision that the ngVLA represents-from searching for Earth-like planets to exploring supermassive black holes.
During the event, guests witnessed a demonstration of the new 18-meter antenna, which features advanced technology such as precision machined and laser etched panels, and structural members constructed of carbon fiber composite materials.This innovative design is expected to set the standard for the approximately 244 18-meter antennas planned for the full ngVLA array.
The ceremony also served as a platform for NRAO leadership and staff to discuss the importance of the ngVLA project with New Mexico and the broader US and international communities. Representatives from local institutions, including the University of New Mexico, attended and emphasized the state’s growing role in global radio astronomy research.
This handover marks a significant step forward in the proposed ngVLA project, setting the stage for further testing and development as New Mexico continues to be a hub for astronomical discovery.
