A bright, icy-looking object floats in deep space at the center of the image, surrounded by a large, glowing blue and pale orange cloud that fades softly into the dark background. The blue part of the cloud is largest and mostly on the left-hand side. The orange part is smaller and on the right-hand side. Small stars are scattered throughout the black sky.

The images here show five planets as observed by VLASS during its all-sky survey. The high resolution of VLASS allows details to be seen in the planetary disks of Mars, Jupiter and Saturn. The "ears" either side of Jupiter are emission from areas of strong magnetic field.

VLASS Sees Planets

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 time plumes of sulfur dioxide (in yellow) rise up from its volcanoes. Jupiter is visible in the background (Cassini image).

Artist illustration of the Dark Ages Polarimetry Pathfinder (DAPPER), which will look for faint radio signals from the early universe while operating in a low lunar orbit. Its specialized radio receiver and high-frequency antenna are currently being developed by NRAO.

Interstellar comet 2I/Borisov, a mysterious visitor from the depths of space, is the first conclusively identified comet from another star. The comet consists of a loose agglomeration of ices and dust particles, and is likely no more than 3,200 feet across, about the length of nine football fields. ALMA observed hydrogen cyanide gas (HCN) and carbon monoxide gas (CO) ejected out of the comet as it approached the Sun and heated up. The ALMA images show that the comet contains an unusually large amount of CO gas. ALMA is the first telescope to measure the gases originating directly from the nucleus of an object that travelled to us from another planetary system.
