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…
GBT-VLBA radar image of the region where Apollo 15 landed in 1971. The snake-like feature is Hadley Rille, a remnant of ancient volcanic activity, probably…
A Blazar in the Early Universe: Details Revealed in Galaxy’s Jet 12.8 Billion Light-Years From Earth
The VLBA image of the blazar PSO J0309+27 is composed of data from three observations made at different radio frequencies. Red is from an observation…

Artist’s illustration of a galaxy in the early universe that is very dusty and shows the first signs of a rotationally supported disk. In this…
Composite image showing Jupiter’s moon Io in radio (ALMA), and optical light (Voyager 1 and Galileo). The ALMA images of Io show for the first…
Artist’s conception of a magnetar — a superdense neutron star with an extremely strong magnetic field. In this illustration, the magnetar is emitting a burst…
Artist’s impression of the explosion and burst of gravitational waves emitted when a pair of superdense neutron stars collide. New observations with radio telescopes show…
Multi-frequency composite VLBA image of the galaxy TXS 0128+554, 500 million light-years from Earth. The image shows young radio jets originating near a supermassive black…
TXS 0128+554, outlined in red here, is an elliptical galaxy located 500 million light-years away in the constellation Cassiopeia. Credit: Sloan Digital Sky Survey Not…
Illustration shows how the star’s motion around the center of mass between it and the planet causes a “wobble” in its motion through space. The…
ALMA image of the planet-forming disk around the young star RU Lup. The inset image (lower left, red disk) shows a previous (DSHARP) observation of…
This artist’s illustration of Supernova 1987A shows the dusty inner regions of the exploded star’s remnants (red), in which a neutron star might be hiding.…
