UrduAlthough the location of St. Croix is perfect for a VLBA antenna, the island poses significant challenges for using and maintaining a radio antenna. The St. Croix dish is located on the eastern side of the island, almost at sea level. So it is constantly bombarded by salt air, ocean rains, and even the occasional tropical storm.

A Surprise Chemical Find by ALMA May Help Detect and Confirm Protoplanets
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets.
NSF Telescopes Image M87’s Supermassive Black Hole and Massive Jet Together for the First Time
Scientists studying the supermassive black hole at the heart of the M87 galaxy have revealed the origins of the monster’s powerful jet and imaged the jet and its source together for the first time. What’s more, the observations have revealed that the black hole’s ring is much larger than scientists previously believed.
Baseline 15: Space Lasers! How Astronomers Use Astrophysical Masers
Artificial lasers on Earth are used for everything from scanning grocery items to delicate surgery. But there are also naturally occurring lasers known as astrophysical masers. Join National Radio Astronomy Observatory as we explore what these “space lasers” tell astronomers about the Universe.
A Decade of Unveiling the Hidden Universe: ALMA at 10
n 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.
Science Highlights 2022: Black Holes, Pulsars and Turbulence
The Universe is a dynamic and exciting place, with stars, planets, and galaxies being born, dying, and undergoing dramatic changes. In 2022, the telescopes of the National Science Foundation’s National Radio Astronomy Observatory (NRAO) revealed fascinating new details about several of these processes, and we’re giving you a taste of the greatest radio astronomy moments of the year.
Baseline 14— Central Development Laboratory: The Magic Behind the Wonder
Radio telescopes are powerful tools that allow astronomers to study the Universe. We often read about the discoveries they make, but we rarely get a glimpse of the engineers and technicians that design and build these telescopes. Join our host Summer Ash as she talks about NRAO’s Central Development Laboratory (CDL) and how CDL helps make modern radio astronomy a reality.
Protected: Science Results From NRAO Facilities to Be Presented at Multiple AAS 241 Press Conferences
Five new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Green Bank Observatory (GBO) will be revealed at multiple press conferences during the 241st meeting of the American Astronomical Society (AAS) from January 8 to 12, 2023, in Seattle, Wash.
NRAO’s Marian Pospieszalski Receives EuMA Pioneer Award
The European Microwave Association (EuMA) has announced Marian Pospieszalski— a senior research engineer at the National Science Foundation’s National Radio Astronomy Observatory (NRAO)— as the recipient of its 2022 Pioneer Award. The EuMA Pioneer Award recognizes individuals responsible for noteworthy advances in the field of microwaves that have had a lasting and significant impact on the microwave community.
NRAO’s Central Development Laboratory to Launch New Women in Engineering Program With Support from the Heising-Simons Foundation
Following a generous grant from the Heising-Simons Foundation, the Central Development Laboratory (CDL) at NSF’s National Radio Astronomy Observatory (NRAO) will soon launch an ambitious Women in Engineering program that will increase opportunities for women to enter the field of radio astronomy through engineering pathways. The program will include a postdoctoral fellowship and a co-op program for undergraduate and graduate students.
ALMA Makes First-Ever Detection of Gas in a Circumplanetary Disk
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— in which the National Radio Astronomy Observatory (NRAO) is a partner— to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What’s more, the detection also suggests the presence of a very young exoplanet.
Out With a Bang: Explosive Neutron Star Merger Captured for the First Time in Millimeter Light
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star.
AUI and NRAO Announce 2022 NAC Bridge Scholarship Recipients
Six NAC alums have accepted offers from outstanding graduate programs around the country. Each will receive a $5,000 AUI Board of Trustees NAC Bridge Scholarship Award, with AUI and NRAO’s congratulations and best wishes for a smooth start to an exciting new chapter of their lives.
Astronomers Reveal First Image of the Black Hole at the Heart of Our Galaxy
At simultaneous press conferences around the world, including at a National Science Foundation-sponsored press conference at the US National Press Club in Washington, D.C., astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.
