Astronomers reveal a new phenomenon dubbed the 'rocking shadow' effect that describes how discs in forming planetary systems are oriented, and how they move around their host star. The effect also ...

Astronomers using ALMA have discovered complex organic molecules, including potential precursors to life's building blocks, in the protoplanetary disc of a young star, V883 Orionis. This finding ...

Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their rotational ...

Astronomers have long struggled to find young planets hidden inside the thick clouds of gas and dust that swirl around new stars. These swirling clouds—called protoplanetary discs—are the birthplaces ...

When astronomers first observed it with the Atacama Large Millimeter/submillimeter Array (ALMA), they saw a smooth, planet-free disc, shown here in the right image. The team, led by Álvaro Ribas, an ...

Stars and their planets form when large molecular clouds collapse in on themselves. Gravity pulls the dust and gas into a violent spiral, which flattens out into a structure known as a protoplanetary ...
