An international team of astronomers used ALMA to capture high-resolution images of eight protoplanetary disks in the Sigma Orionis cluster, which is irradiated by intense ultraviolet light from a massive nearby star. To their surprise, they found evidence of gaps and rings in most of the disks—structures commonly associated with the formation of giant planets, like Jupiter.

Astronomers Discover New Building Blocks for Complex Organic Matter
There should be a lot of carbon in space, but surprisingly, it’s not always easy to find. While it can be observed in many places, it doesn’t add up to the volume astronomers would expect to see. The discovery of a new, complex molecule (1-cyanopyrene), challenges these expectations, about where the building blocks for carbon are found, and how they evolve.
Massive Stars Born from Violent Cosmic Collapse
An international team of astronomers has observed evidence that massive stars can be born from rapidly collapsing clouds of gas and dust, challenging long-held assumptions about star formation.

The Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia, US is the world’s largest fully steerable radio telescope. It is situated in the National Radio Quiet Zone, a unique area where authorities limit all radio transmissions to avoid emissions toward the GBT. The location of the telescope within the Radio Quiet Zone allows for the detection of faint radio-frequency signals from the universe, which man-made signals might otherwise mask. The observatory borders National Forest land, and the Allegheny Mountains shield it from some radio interference. The telescope’s location has been the site of important radio astronomy telescopes since 1957. It currently houses seven additional telescopes, and in spite of its somewhat remote location, receives about 40,000 visitors each year, from high school students to PhD candidates to visiting researchers. Since October 1, 2016, the telescope has been operated by the newly separated Green Bank Observatory to deal with pending budget cuts. The telescope honors the name of the late Senator Robert C. Byrd who represented West Virginia and who pushed the funding of the telescope through Congress.
