Artist’s conception of a neutron star with an ultra-strong magnetic field, called a magnetar, emitting radio waves (red). Magnetars are a leading candidate for what…
Scientists have observed, for the first time, the mysterious death throes of a carbon-rich asymptotic branch star (AGB). V Hydrae’s final act is characterized by…
Artist impression of the 14 galaxies detected by ALMA as they appear in the very early, very distant universe. These galaxies are in the process…
Scientists have made the first comprehensive multi-wavelength observational study of an intruder object disturbing the protoplanetary disk—or birthplace of planets—surrounding the Z Canis Majoris star…
The VERTICO—Virgo Environment Traced in Carbon Monoxide—Survey observed the gas reservoirs in 51 galaxies in the nearby Virgo Cluster and found that the extreme environment…
Artist’s conception of the central portion of the Next Generation Very Large Array. Credit: Sophia Dagnello, NRAO/AUI/NSF NRAO project ranked as important new initiative. The…
This artist’s conception shows the dust continuum and molecular lines of carbon monoxide and water seen in the pair of galaxies known as SPT0311-58. ALMA…
This composite image of galaxy cluster MACSJ 0138 shows data from the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Hubble Space Telescope. The magnified section…
This composite image shows three radio-telescope views of the central region of the galaxy Messier 87 (M87), where a jet of fast-moving particles is ejected…
Partially processed view of the Tycho Crater at a resolution of nearly five meters by five meters and containing approximately 1.4 billion pixels, taken during…
This composite image of ALMA data from the young star HD 163296 shows hydrogen cyanide emission laid over an artist’s impression of a starfield. The…
Artist’s conception of the explosion resulting from the collision of two neutron stars. Credit: D. Berry, O. Gottlieb, K. Mooley, G. Hallinan, NRAO/AUI/NSF The National…
Fast-moving debris from a supernova explosion triggered by a stellar collision crashes into gas thrown out earlier, and the shocks cause bright radio emission seen…
Shown here in composite view, ALMA data (red/orange) reveals filament structures left behind by ram pressure stripping in a Hubble Space Telescope optical view of…
Using the Atacama Large Millimeter/submillimeter Array (ALMA), scientists completed a census of nearly 100 galaxies in the nearby universe, showcasing their behaviors and appearances. The…
Protoplanetary disks are classified into three main categories: transition, ring, or extended. These false-color images from the Atacama Large Millimeter/submillimeter Array (ALMA) show these classifications…
Using gas velocity data, scientists observing Elias 2-27 were able to directly measure the mass of the young star’s protoplanetary disk and also trace dynamical…
Artist’s conception of the young star Cep A HW2, showing a wide-angle wind originating close to the star and a disk of material orbiting the…
Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists conducted a census of nearly 100 galaxies in the nearby Universe. This census helped them to characterize…
