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.

A team of astrophysicists and computational astronomers have discovered why sibling stars look alike – those formed from a single cloud share the same chemical fingerprint due to early, fast and turbulent mixing of gas in the giant molecular clouds where star formation occurs.

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 Search For Cause Of Massive Star Formation
2013-12-21 04:25:12

In an attempt to determine why massive stars – those with at least eight times the mass of our Sun – grow so much larger than most other stars in our galaxy, astronomers used the ALMA telescope to examine the cores of Infrared Dark Clouds roughly 10,000 light-years away.

Molecular Cloud Explains Star Formation

The molecular clouds that float about the universe hold the ingredients for star formation, say researchers at University of California, San Diego.

Astronomers Find Huge 'Hot Core' Enveloping Infant Star
2013-10-04 13:31:43

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.

Mapping Location Of Galactic Clouds

Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.

ALMA Scan Reveals Embryonic Star Formation
2013-07-10 05:07:12

Astronomers used ESO's Atacama Large Millimeter/submillimeter array to gain one of the best views yet of a star in the process of forming.

Astronomers Capture Rare Glimpse Of Star-Forming Region In Visible Light
2013-01-16 07:00:46

The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery.

Star Formation In Barnard 68
2012-10-30 11:40:17

A team from Max Planck Institute for Astronomy has observed the earliest stages of star formation using the European Space Agency's Herschel Space Observatory.

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...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

Interstellar Cloud -- Interstellar cloud is the generic name given to accumulations of gas and dust in our galaxy. Depending on the density, size and temperature of a given cloud, the hydrogen in it can be neutral (HI clouds) or molecular (molecular clouds). Chemical compositions Analysing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them. Large radio telescopes scan the intensity in the sky of particular frequencies of...
