False color image of protoplanetary disks side by side. Left is a ring disk showing blue scattered outer ring, green inner rings with gaps, and a yellow core. Center is a transition disk with a thin outer blue ring and thin green and yellow rings, and a large empty cavity in the center. Right is a compact small disk with thin blue and green rings, and a large inner yellow core with no gaps.
Mind the Gap: Scientists Use Stellar Mass to Link Exoplanets to Planet-Forming Disks
June 23, 2021 at 4:00 am | News Release

Using data for more than 500 young stars observed with the Atacama Large Millimeter/Submillimeter Array (ALMA), scientists have uncovered a direct link between protoplanetary disk structures—the planet-forming disks that surround stars—and planet demographics. The survey proves that higher mass stars are more likely to be surrounded by disks with “gaps” in them and that these gaps directly correlate to the high occurrence of observed giant exoplanets around such stars. These results provide scientists with a window back through time, allowing them to predict what exoplanetary systems looked like through each stage of their formation.

A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation.

Cosmic Cartographers Map Nearby Universe Revealing the Diversity of Star-Forming Galaxies
June 8, 2021 at 8:15 am | News Release

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has completed the first census of molecular clouds in the nearby Universe. The study produced the first images of nearby galaxies with the same sharpness and quality as optical imaging and revealed that stellar nurseries do not all look and act the same. In fact, they’re as diverse as the people, homes, neighborhoods, and regions that make up our own world.

NRAO, Green Bank Telescope, and Raytheon Intelligence & Space (RI&S) are working in collaboration to improve planetary radar capabilities. With the addition of Qorvo’s Spatium power amplifier technology, the project now has the power to identify and characterize even small NEOs earlier with more precision.

A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars.
