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 ...

The Wolfe Disk, a massive rotating disk galaxy in the early universe, was discovered in 2017 when a stargazing project in the Chilean desert examined light from a distant quasar (top left) absorbed in ...

Figure 1: Jet, disk, and outflow in the HH 211 protostellar system. (Top) A composite image showing the jet system. (Bottom) A zoom-in to the innermost region around the central protostar, showing the ...

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 ...

(Nanowerk News) In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large ...

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 ...

New ALMA observations of protoplanetary disks allow us to probe planet formation in other systems, giving us new constraints on planet formation processes. Meanwhile, studies of our own Solar System ...

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 ...
