What are star clouds?
Definition of star cloud 1 : a large luminous patch of the Milky Way that can be resolved with optical aid into great numbers of stars appearing to be more densely concentrated than in adjoining areas. 2 : an enormous aggregation of stars forming one of the units comprising the nucleus or a spiral arm of a spiral …
Do stars have clouds?
Stars are born in clouds of gas and dust. Turbulence from deep within these clouds creates high density regions called knots. These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction.
What are star clouds made of?
The space between the stars in a galaxy is called the interstellar medium, because it is the medium, or substance, that makes up the space between stellar objects. The regions of gas and dust are called molecular clouds, because of their content. Molecular clouds are made of a mix of atoms, molecules, and dust.
Are stars clouds of dust?
Star Formation Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
Are stars still being born?
The central core of our galaxy is not a friendly place for star formation, and yet new observations have revealed almost four dozen newly-forming systems. However, our observations prove that even in the strongly disturbed areas around the Galactic Center, baby stars still form.”
How old are the stars we see today?
For the most part, the stars you see with the naked eye (that is, without a telescope) are still alive. These stars are usually no more than about 10,000 light years away, so the light we see left them about 10,000 years ago.
What is T Tauri stage?
It begins life as a protostar still enshrouded in its natal molecular cloud, accreting new material and developing a proto-planetary disc. Slowly, stellar winds and radiation blow away the surrounding shell of gas and dust, and the third stage, when the surrounding envelope has cleared, is called the T-Tauri phase.
