A trio of researchers with the European Southern Observatory and Université Côte d'Azur has found evidence showing that the gas and dust disks that form around early stars systems do not contain enough material to form ...
Measuring the vast quantities of cosmic dust in interstellar space may be a key to unlocking various mysteries of the cosmos, including how the grains form and whether new types of galaxy are obscured by the particle clouds.

An international team of researchers has discovered what they describe as an inside-out planetary nebula—a planetary nebula with surroundings that are the opposite of what normally occurs. In their paper published in the ...
A European team of astronomers has discovered that dust particles around a star already coagulate before the star is fully grown. Dust particle growth is the first step in the formation of planets. The researchers from the ...
