Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Very Long Baseline Array
The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It’s the world’s sharpest, dedicated telescope array.
When a star begins to form, the heat and pressure generated during the initial collapse of a protostar can…
Astrophysical masers are microwave lasers that occur naturally in space. They are found in regions of gas that have…

Galaxies are often surrounded by a halo of hydrogen gas. Over time a galaxy can lose this halo, which…
North Pole of the MoonRadar maps can look like optical images, but they represent the amount of energy reflected back toward the transmitter by any given part of the Moon's surface. The Arecibo Telescope's radar wavelength of 70 cm penetrates 10 meters or more into the very dry lunar surface. When it bounced back to the Green Bank Telescope, (GBT), it reveals variations in the abundance of rocks larger than about 10 cm in diameter and differences in the chemistry of rocks that form the Moon's crust.

Book Release: “Joe Pawsey and the Founding of Australian Radio Astronomy”
This book was more than 15 years in the making, and it is a collaboration of three authors across two continents who worked together to bring to light the story of Joe Pawsey, a key figure in Australian science and, especially, radio astronomy.
$21 Million NSF Award Will Bring ngVLA Design to Life
The largest astronomical array in North America is one step closer to becoming a reality. The National Radio Astronomy Observatory (NRAO) is pleased to announce that the National Science Foundation (NSF) has awarded a 3-year, $21 million grant to Associated Universities, Inc.(AUI) to further the design of the next generation Very Large Array (ngVLA).
NRAO First Wave Completed 20 Weeks of Amateur Radio Learning Program for BIPOC and LGBTQIA+ Learners
Following a grant from Amateur Radio Digital Communications (ARDC), the National Science Foundation‘s (NSF’s) National Radio Astronomy Observatory (NRAO) launched a two-year project to engage BIPOC and LGBTQIA+ learners in learning about the electromagnetic spectrum and discovering the excitement of ham radio. The project, Exploring the Electromagnetic Spectrum (EMS) with Amateur Radio, offered its first learner-facing training in January 2023.
NRAO Honors Pride Month: Seeing the Whole Picture
The NRAO has made a visible change to our logo for Pride month, because we want to send the clear message that NRAO values our current and future LGBTQIA+ colleagues, friends, and family members. We send this same message internally by taking seriously our obligation to create and maintain an environment that is safe, secure, and welcoming.
What is Radio Astronomy? Astronomers around the world use radio telescopes to observe the naturally occurring radiowaves that come…
Different star types “live” and “die” in different ways based on how much matter they started with and if they were born with siblings nearby.
