Over time, radiation pressure from the cluster will disperse the molecular cloud.
Young open clusters may be contained within the molecular cloud from which they formed, illuminating it to create an H II region.
What would The StarryNight look like with a background formed from a“real” molecular cloud?
In a follow-up they studied 110 molecular clouds, at distances between 300 and 1300 light-years, and which had been part of previous Spitzer surveys.
Though the effect is not fully understood,the strength of a magnetic field may affect molecular clouds.
The stars in the bright starcluster at the centre of this photo all formed from the same molecular cloud, and the Bok globule next to it is the little material that was left over.
One of the most identifiable nebulae in the sky, the Horsehead Nebulain Orion, is part of a large, dark, molecular cloud.
In the southeast the blast wave is interacting with a very dense(~10,000 cm- 3)and clumpy molecular cloud, such that the emitting shocked gas has a ring-like shape.
Researchers found that star formation in Cepheus B is mainly triggered by radiation from one bright,massive star(HD 217086) outside the molecular cloud.
The entire cosmic vista spans over 30 light-years,near the edge of the Orion Molecular Cloud Complex some 1,500 light-years distant.
The Serpens Molecular Cloud containing star-forming regions W40 and Serpens south is often included in Gould Belt surveys, but is not formally part of the Gould Belt due to its greater distance.
Since then, stars have formed by the collapse of small, dense core regions in large,cold molecular clouds of hydrogen gas.
It is similar in nature to the Bubble Nebula,but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
Also known as Messier 42(M42), the Orion Nebula spans about 24 light-years across andis part of the much larger Orion Molecular Cloud Complex.
The Spitzer data, in red, green and blue shows the molecular cloud(in the bottom part of the image) plus young stars in and around Cepheus B, and the Chandra data in violet shows the young stars in the field.
It was only by luck that thisatom we're following wound up in a dense molecular cloud, shielded from this radiation.
Not far on the sky from the famous Double Star Cluster in Perseus, IC 1795 is itself located next to IC 1805, the Heart Nebula, as part of a complex of starforming regions that lie at the edge of a large molecular cloud.
Eventually, after about 800 million years, the gravitational disruption caused by galactic tides,passing stars and giant molecular clouds began to deplete the cloud, sending comets into the inner Solar System.
A molecular cloud, sometimes called a stellar nursery if star formation is occurring within, is a type of interstellar cloud whose density and size permits the formation of molecules, most commonly(H2).
It sits just to the south of star Alnitak, the easternmost of Orion's famous three-star belt,and is part of the vast Orion Molecular Cloud complex.
Star-forming regions and OB associations that make up this region include the Orion Nebula andthe Orion molecular clouds, the Scorpius-Centaurus OB Association, Cepheus OB2, Perseus OB2, and the Taurus-Auriga Molecular Clouds.
Researchers Laurent Pagani(CNRS, Paris Observatory), Jürgen Steinacker(Max Planck Institute for Astronomy) and colleagues from the California Institute of Technology and Laboratoire d'Astrophysique de l'Observatoire de Grenoble,discovered surprisingly bright mid-infrared radiation from the core of the molecular cloud L183 in the constellation Serpens Cauda 360 light-years away.
The formation of a star begins with a gravitational instability inside a molecular cloud, which is often triggered by shockwaves from supernovae(massive stellar explosions) or the collision of two galaxies(as in a starburst galaxy).
Spiral arms arehome not only to larger numbers of molecular clouds, whose gravity may distort the Oort cloud, but also to higher concentrations of bright blue giants, which live for relatively short periods and then explode violently as supernovae.[124].
