This blog post celebrates highlights from the brilliant career of astronomer Paul Vanden Bout, who recently received the Karl G. Jansky Lectureship from NRAO. Vanden Bout's vision for millimeter-wavelength astronomy led to the creation of several major radio telescopes around the world.
Gravity can focus light like a lens, allowing astronomers to see distant galaxies and explore dark matter. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how astronomers use gravitational lensing to study the universe..
Many objects in the Universe have magnetic fields. Planets such as Earth and Jupiter, the Sun and other stars, even galaxies billions of light years away.
On August 20, 2023, the National Radio Astronomy Observatory (NRAO) marked 30 years since the National Science Foundation’s Very Long Baseline Array (VLBA) had its inauguration ceremony in the high desert of New Mexico. In the three decades since, the VLBA has become not only one of the world’s most famous radio telescopes, but has also played a key role in radio astronomy across the country and the world.
A study of rare megastorms on Saturn using data from the National Science Foundation’s Karl G. Jansky Very Large Array has revealed disruptions in the distribution of ammonia gas in the planet’s deep atmosphere. The findings raise questions about just how different gas giants can be from each other, and challenge scientists’ understanding of how megastorms may form on planets other than Earth. The results of the study appear in Science Advances.
Although 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.
Fast radio bursts are powerful flashes of light that shine for only milliseconds. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how astronomers study these mysterious bursts, and what might be causing them.
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.
While studying classical novae using the National Radio Astronomy Observatory’s Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations, which detected non-thermal emission from a classical nova with a dwarf companion, were presented today at a press conference during the 242nd proceedings of the American Astronomical Society in Albuquerque, New Mexico.
Tras estudiar estrellas novas clásicas con el Long Baseline Array (VLBA) del Observatorio Radioastronómico Nacional de Estados Unidos, una estudiante de posgrado descubrió pistas de que estos objetos no son tan simples como se creía. Las nuevas observaciones, en las que se detectaron emisiones no térmicas de una nova clásica con un objeto compañero enano, se presentaron hoy durante la 242 asamblea de la Sociedad Astronómica de Estados Unidos, celebrada en Albuquerque (Nuevo México).
New scientific results from the Very Long Baseline Array (VLBA), the Very Large Array (VLA), and the Green Bank Observatory (GBO) will be revealed at multiple press conferences during the 242nd meeting of the American Astronomical Society (AAS) from June 5-7, in Albuquerque, New Mexico.The AAS meeting includes a series of press conferences based on a range of themes.
Two student researchers from the National Radio Astronomy Observatory’s National Astronomy Consortium (NAC) program were each awarded the prestigious Chambliss Astronomy Achievement Student Awards medal during the 241st proceedings of the American Astronomical Society (AAS).
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.
Un equipo científico que estudió el agujero negro supermasivo presente en el corazón de la galaxia M87 reveló los orígenes de su poderoso chorro y logró obtener las primeras imágenes del chorro y su fuente juntos. Las observaciones también revelaron que el anillo del agujero negro es mucho más grande de lo que la comunidad científica creía.
As a part of its central mission to nurture and inspire the next generation of radio astronomers, the National Science Foundation’s National Radio Astronomy Observatory (NRAO) has selected four outstanding early career professionals for its 2023 Jansky Fellowship.
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.
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.
Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest that the water in our Solar System formed billions of years before the Sun.
Un equipo científico detectó agua en el disco circumestelar de una protoestrella cercana gracias al Atacama Large Millimeter/submillimeter Array (ALMA). Es la primera vez que se observa agua depositándose en un disco protoplanetario sin que se produzcan cambios significativos en su composición. Este hallazgo permite suponer que el agua presente en nuestro Sistema Solar se formó miles de millones de años antes que el Sol.
While studying galaxies in the early Universe with the Atacama Large Millimeter/submillimeter Array (ALMA), scientists discovered one of the most extreme galaxies ever recorded in the early Universe. What’s more, it was hiding a unique supermassive black hole (SMBH). The observations could unlock clues about the early formation of these violent giants and how to find them.
