Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas. The star, called 49 Ceti, is 40 million years old and ...

Leonardo Testi and team investigate the initial conditions for planet formation in this special astronomy focus ...

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...

Astronomers have unveiled the largest planet-forming disk ever observed around a young star, a sprawling structure where gas ...

A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO 2) in ...

Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists ...

We were astonished to see just how asymmetric this disk is,” says Joshua Bennett Lovell of the Center for Astrophysics. That understatement frames one of the most remarkable protoplanetary systems ...

Space experts believe that the 'Dracula' disc could offer new insights into planetary formation, especially in massive ...
