Latest Protostar Stories
NASA astronomers have for the first time detected an outburst from a star believed to be in the earliest stages of its development – an eruption that they believe reveals a sudden accumulation of gas and dust by an exceptionally young star also known as a protostar.
Catching the formation of a single star is a tough thing to do, and yet a large team of international astronomers has announced the discovery of four stars all forming in the same system.
Something seems to be missing in a new image captured by the European Southern Observatory (ESO) this week – there’s a large patch of darkness where there should be stars.
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.
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...
