The Parallax Technique
The parallax technique determines distance by measuring the angle of apparent shift in an object's position, as seen from opposite sides of Earth's orbit around the Sun. Using this method, astronomers were able to directly measure the distance to a region on the far side of our Milky Way Galaxy, past the Galaxy's center.NRAO Making Waves

A Decade of Unveiling the Hidden Universe: ALMA at 10
On March 13th, 2023, astronomers around the world will mark the 10th anniversary of the inauguration of the Atacama Large Millimeter/submillimeter Array (ALMA), the world’s largest radio telescope. Over the past decade, the international ALMA collaboration— led by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO), the European Southern Observatory (ESO), and the National Astronomical Observatory of Japan (NAOJ)— has revolutionized our understanding of the Universe and unveiled its secrets, from the formation of planets, stars, and galaxies to deciphering the chemistry of the cosmos, and even taking part in capturing the first images of black holes.

NSF and SpaceX Finalize Radio Spectrum Coordination Agreement
The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a .statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO). The agreement will also positively impact collaborations and cooperation between SpaceX and NSF’s NOIRLab.
