Latest Protostar Stories
New modeling studies from Carnegie’s Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up.
Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. However, astronomers have recently discovered that filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found that some protostars in the Orion Nebula are doomed from the beginning.
A team of scientists led by the University of Tokyo say that the chemical compositions of an interstellar cloud and the disk are not identical.
Astronomers using the Very Large Array (VLA) have made a discovery that helps explain how double-star systems form.
Using the Atacama Large Millimeter Array telescope in northern Chile, scientists have identified a very young star in our galaxy which had such an explosive birth, it used to be about 100 times brighter than it is now.
Astronomers have discovered an infant star while looking at an infrared dark cloud that is about ten times larger than those found around typical solar-mass baby stars.
This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast.
Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...
Star Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...
