A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than Earth that are the most abundant type of planet in the galaxy.

Iron meteorites of the solar system are composed of parent cores belonging to the earliest credited bodies of the environment. The cores are formed in two isotopically distinct reservoirs including non-carbonaceous and carbonaceous ...
Astronomers from the Queen's University in Kingston, Canada and elsewhere, have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a mysterious source known as VLA 1623 West. Results of the study, published ...
Astronomers agree that planets are born in protoplanetary disks—rings of dust and gas that surround young, newborn stars. While hundreds of these disks have been spotted throughout the universe, observations of actual planetary ...
