Observations of the interstellar medium, together with calculations of stellar models have led astrophysicists to assemble a theory of how stars are born and why they shine. The theory of stellar genesis has been successful in explaining how stars are formed in vast clouds of interstellar gas and dust.

The visible light image does not show many features because optical telescopes cannot see past the thick areas of dust and gas in which new stars are formed. By contrast, in the infrared we can "see" past the dust.

Pressure from fast moving electrons keeps these stars from collapsing. The more massive the core, the denser the white dwarf that is formed. ... Nova is Latin for "new" - novae were once thought to be new stars. Today, we understand that they are in fact, very old stars - white dwarfs. If a white dwarf is close enough to...

In the enormous space between the stars large dust nebulae exist, that consist of gas molecules and dustparticles. These clouds are very thin but still stars are formed of them. The birth of a star. ; A star is formed when matter in ... This causes a rise in temperature inside the star and a new nuclear reaction starts.

New stars come in a variety of sizes and colors. They range from blue to red, from less than half the size of our Sun to over 20 times the Sun’s size. It all depends on how much gas and dust is collected during the star's formation.

Listening in, they have learned that these hidden pockets of space are the places where most of the new stars that populate a galaxy are born. ... Of special interest to astronomers is the potential for protostars to form planetary systems. The stars are formed from large disks of cool dust and gas, known as accretion...

New three-dimensional simulations published in Science show the series of steps by which the uneven fog of hydrogen atoms present before stars took shape would have clumped into protostars—dense balls of hydrogen just 1 percent the mass of the sun. ... Stars and galaxies formed in areas where gas was concentrated.
